Answer:
The carriers that move energy from the light-dependent reactions to the Calvin cycle reactions can be thought of as “full” because they bring energy. After the energy is released, the “empty” energy carriers return to the light-dependent reactions to obtain more energy. You should be familiar with the energy carrier molecules used during cellular respiration: NADH and FADH2. Photosynthesis uses a different energy carrier, NADPH, but it functions in a comparable way. The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH. When NADPH gives up its electron, it is converted back to NADP+.

The__________is a range of wavelengths and frequencies of electromagnetic radiation.
A ______________ is the distance between the crest of successive waves.
What is frequency?
What is the relationship between wavelength and frequency of radiation on the electromagnetic spectrum.
______________ at astronomical observations capture this light even better, providing a clearer picture of out galaxy.
Answer: Electromagnetic spectrum.
Explanation: It is composed of Gamma rays with the highest energy to radio waves with the lowest energy. It between in descending order (with regard to energy) is; X-rays, Ultraviolet, Visible Light, Infrared, Microwave. The higher the energy level the lower the wavelength and the higher the frequency.
Answer: Wavelength
Explanation: Ideally, the wavelength is the distance between two consecutive identical phases of a wave. It could be a peak to another peak or a trough to another trough. Usually, the lower the energy level of the wave, the bigger the wavelength and vice versa. It is measured in meters, millimeters or even picometers depending on the size of the wavelengths.
Explanation: Frequency is the amount of time that it takes for a wave to complete once a cycle, that is, to repeat a phase. Gamma rays have the highest frequency in the electromagnetic spectrum while radio waves have the lowest.
Explanation: Frequency is indirectly proportional to wavelength. This means that the higher the frequency the smaller the wavelength and vice versa. In addition, therefore, converse to wavelength, the higher the energy of a wave, the higher the frequency and vice versa. It is calculated by dividing one (1) with the wavelength of the wave. It is measured in Hertz
Answer: Telescopes
Explanation: Their basic principle of telescopes is that they collect as much light as possible from the aperture (this is why the front end is usually large diameter), and then converges this light using lenses and prisms onto a film. This gives a clear picture from which astronomical features can be clearly discerned,
The electromagnetic spectrum is a range of wavelengths and frequencies of electromagnetic radiation. Frequency refers to the number of oscillations or cycles that occur per unit of time. Telescopes used in astronomical observations capture this light even better, providing a clearer picture of our galaxy.
Explanation:The electromagnetic spectrum is a range of wavelengths and frequencies of electromagnetic radiation. The wavelength is the distance between the crest of successive waves. Frequency refers to the number of oscillations or cycles that occur per unit of time.
The relationship between wavelength and frequency on the electromagnetic spectrum can be described by the wave equation: wavelength = speed of light / frequency. As wavelength decreases, frequency increases, and vice versa.

Which nucleotide in Figure 13-1 indicates the nucleic acid is RNA?
Guanine
uracil
cytosine
adenine
NEED HELP ASAP!!!!!!!!
Answer:
Uracil
I hope that helps with everyone
Final answer:
Uracil is the nucleotide that indicates the nucleic acid is RNA, as it replaces thymine which is found in DNA.
Explanation:
The nucleotide that indicates the nucleic acid is RNA is uracil. Both DNA and RNA contain the nitrogenous bases adenine, guanine, and cytosine. However, only RNA contains uracil, which replaces thymine that is found exclusively in DNA. In RNA, uracil pairs with adenine, and this pairing is a defining characteristic distinct from the adenine-thymine pairing seen in DNA. Therefore, seeing uracil in a nucleic acid structure is indicative that the molecule is RNA, distinguishing it from DNA.
Steve and Barry are racing each other, and Barry is winning.
If Barry is moving faster than Steve, from which reference point is Barry's position increasing through time?
A. an observer in front of Steve and Barry
B. Barry's reference point
C. Steve's reference point
D. he finish line
Answer:-
The correct option can be option C.
Answer:
C. Steve's reference point
Explanation:
Reference point is a body that we adopt as a reference to analyze a given phenomenon. The reference we adopt most often is the earth. Rest happens whenever a body does not change its position relative to a given reference.
In this case, if Barry is moving faster than Steve, we can conclude that the point of reference for Barry's speed is Steve's reference point, since we are comparing Barry's speed to where Steve is. So it would be correct to say "Barry is moving faster than Steve."

The backbones of DNA and RNA are
A. identical.
B. very different, made of nucleotides in DNA and amino acids in RNA.
C. made of alternating sugars and phosphate groups.
D. made of a chain of base pairs.
Answer:
The answer is very likely C.
Explanation:
This becomes easy once we remember that DNA and RNA are not identical - which is why they have different names, RNA = 'ribo', DNA = 'deoxy.' This eliminates choice (A). While they are different, they are not incredibly different - DNA and RNA are both made up of nucleotides - they are not however, made up of Amino acids. Amino acids are what they can code for, and subsequently create proteins during protein synthesis. This helps us eliminate (B). Finally, we know that in order for something to have base pairs it needs to be double stranded - which RNA is not. Which means that because RNA is not double stranded (its singly stranded) that the answer cannot be (D). Leaving us with the only plausible option; (C).
The backbones of both DNA and RNA consist of nucleotides made of sugars, phosphate groups, and bases, with DNA using deoxyribose and thymine, whereas RNA uses ribose and uracil, making option C the correct answer.
The backbones of DNA and RNA are composed of a chain of nucleotides, which include a sugar, a phosphate group, and a base. However, the sugar in the DNA backbone is deoxyribose, while in RNA, it is ribose. Moreover, DNA contains the base thymine, unlike RNA, which contains uracil instead of thymine. Therefore, while they have a similar structure regarding their backbone, composed of a sugar-phosphate chain, the precise components and bases do differ between the two.
In conclusion, the backbones of DNA and RNA are made of alternating sugars and phosphate groups, but are not identical due to the differences in the sugar component and the bases they contain. The correct answer to the provided question is C: made of alternating sugars and phosphate groups.
list two ways in which water reaches the ocean
Answer:
Precipitation and runoff
Explanation:
The oceans get water in several different manners, with some of them being through precipitation, and through runoff. Whenever there is precipitation on the ocean waters, the water from it of course ends up in it, thus it accumulates it. Also, when there's precipitation on the land, a runoff appears. The runoff is simply the water from the precipitation that moves on the surface, downhill, and usually ends up in some water body. Part of the runoff ends up in the oceans, and that is the runoff that appears on the slopes that are near the ocean and are sloping toward the ocean waters.
Final answer:
Water reaches the ocean through surface runoff and groundwater discharge that feeds into streams and rivers, and via ocean currents and upwelling, which recycle water through the ocean's depths and surface.
Explanation:
Ways Water Reaches the Ocean
Water reaches the ocean through various complex processes. Here are two primary ways:
Surface Runoff and Groundwater Discharge: Water that falls as precipitation on land can travel as overland flow or through groundwater systems to eventually reach streams and rivers, which carry it to the ocean. This process involves surface runoff from rain and melting snow, which collects in rivers and lakes, and groundwater discharge where water infiltrates into the soil and joins aquifers that feed into larger bodies of water.
Ocean Currents and Upwelling: Ocean water is constantly on the move, affected by surface currents driven by global wind patterns, and the mixing of different water densities. Dense water sinking in certain areas, like off Antarctica, causes deeper water to move along the ocean bottom, eventually rising elsewhere in a process known as upwelling, which also contributes to water reaching the ocean.
Both of these processes are integral to the global water cycle where water from the oceans evaporates, condenses into clouds, and falls back to Earth as precipitation, completing the cycle when it returns to the ocean.
The chemicals used on farms, golf courses, and domestic gardens are often to blame when groundwater becomes contaminated with A. Acid B. Nitrates C. Fuel D. Sewage
Answer:
Nitrates
Explanation:
A. Acid-- acid is right, but not the best answer.
B. Nitrates are fertilizers, which are things that would be used in all of these situations
C. Fuel-- no one is pouring gasoline on their grass to make it grow.
D. Sewage-- same as gas, but this time it is sewage.
Answer:
The correct answer is option B i.e. Nitrates.
Explanation:
1. The golf courses, or cricket and football grounds need a thick sheet of grass growing on them for their perfect performance. Farms do need grasses for animals.
2. Acid is not poured on the grasses to grow. Some nitrates poured on grass may convert into nitric acid, but its not significant.
3. Fuel and sewage are also not poured on golf courses or farms to grow grasses.
4. But nitrates are good fertilizers which leads to growth of grasses and plants, needed for farms and golf courses.
The MOST accurate way to determine the evolutionary relationship between two animals is through the examination of
A) common behaviors.
B) similar physical features.
C) DNA or protein sequences of shared genes.
D) fossilized ancestors that they may have in common
Answer:
DNA or protein sequences of shared genes.
Explanation:
i hope this help
The correct answer is C. DNA or protein sequences of shared genes.
Explanation:
Evolution is a major theory in biology that purposes over time organisms change and they even led to new species due to changes or mutation in genes and observable traits. According to evolution, related organisms evolved from a common ancestor and therefore they have similar DNA or proteins sequences that lead to common features.
According to this, the most accurate way to know whether two or more organisms are related or not or their evolutionary relationship is through DNA or protein sequences of shared genes because only organisms that evolved from a common ancestor would share part of their DNA or protein sequences. Also, common behaviors or physical features do not necessarily show an evolutionary relationship.

The karyotype represents a meiotic accident called nondisjunction which, in this case, results in a condition called Turner's syndrome. This condition causes females to be short in stature, lack secondary sex characteristics, and to be sterile. Thus, option D is correct.
What is Nondisjunction ?Nondisjunction has the inability of the sister chromatids or the homologous chromosomes to correctly split during cell division (mitosis/meiosis). Nondisjunction will take one of three different forms:
failing to the separate a homologous pair of the chromosomes during meiosis I; failing to separate sister chromatids during meiosis II; failing to the separate sister chromatids during mitosis. Daughter cells with aberrant chromosomal numbers occur from nondisjunction (aneuploidy).Before the somatic cells has been divide by the mitosis, the genetic material has been replicated in the S phase. Each chromosome has been made up of two sister chromatids that has been joined at the centromere. The cell divides, the sibling chromatids that separate and move to opposing cell poles during the anaphase of mitosis.
Therefore, option D is correct.

Global warming is a gradual increase in the temperature of the earth surface and atmosphere all around the world. It is caused due to the greenhouse effect of increased level of green house gases such as carbon dioxide, CFCs, etc. There are various types of pollutants also which involved in increasing the atmospheric temperature of the earth. Increasing use of fossil fuels by the people and deforestation is increasing carbon dioxide emissions which trap heat and cause greenhouse effect. Water vapor is also a significant greenhouse gas which is not directly produced by humankind but involve in global warming hugely. A slight increase in the level of CO2 causes marked increase in earth temperature. Green house gases absorb and re-radiate infrared radiations which ultimately cause green house effect. Because of deforestation, CO2 is not absorbed well and remain in the atmosphere for long time and trap heat.
Global warming has hugely impacted the environment and human life to a great extent for many years. The level of sea water is increasing continuously every year and creating fear for the nearby cities, islands and seawater animals. Rainfall pattern has also disturbed which causes drought in some areas and flooding in other areas. Ice caps and glaciers are melting continuously and its level depends on the increased level of temperature. It is causing loss of habitat near to the poles and polar bears have greatly endangered. Wild animals living in the forest are endangered because of their habitat loss due to deforestation.
Bleaching of Coral Reefs and loss of Plankton are done due to warming seas and acidification (carbonic acid formation. Various types of diseases are also spreading especially malaria to the nearby regions. Now, it has become very necessary for the countries worldwide especially developed countries to reduce their carbon emission as quickly as possible. US need to reduce its carbon emission to a great extent in order to solve the problem of global warming. Limiting some of the promising sectors like coal-fired electricity and wind power can reduce in carbon emissions in nearby decades.
Global warming is the all over rise in temperature of the earth surface. It has affected the environment and whole atmosphere and has resulted into the huge level climate change. A huge change in the earth’s climate system because of the global warming is observed in the recent past years. The effects of increased global temperature are melting ice, warmed continents, increasing sea level, seasonal changes, climate changes, changing precipitation, expansion of deserts in the subtropics regions, etc. Intergovernmental Panel on Climate Change (IPCC) has reported in 2014 that according to scientists, global warming is mostly a human being created environmental issue. It is mainly caused by ever increasing level of greenhouse gases on the earth.
Impacts of global warming differ from region to region all over the world. Retreat of glaciers, sea ice, more frequent extreme weather events, heat waves, heavy rainfall and snowfall, droughts, floods, ocean acidification, species extinctions, etc are some huge impacts of shifting temperature regimes. In order to reduce the effect of global warming, effective societal responses are needed to be implemented and followed urgently.

The Circulatory Systems Job Is To Transport Materials Throughout The Body. It Consists Of The HEART, BLOOD And BLOOD VESSELS.
Final answer:
The circulatory system, also known as the cardiovascular system, is vital for transporting materials such as oxygen, nutrients, and hormones throughout the body and is composed of the heart, blood vessels, and blood. It has two main circulations: pulmonary and systemic.
Explanation:
The circulatory system is an essential component of the human body tasked with the transportation of materials like nutrients, oxygen, and hormones to cells, and the removal of waste products away from cells to maintain homeostasis. At the heart of the system, quite literally, is the heart, a muscular organ that pumps blood through a vast network of blood vessels, such as arteries, veins, and capillaries. This system can be broken down into two main circulations: the pulmonary circulation, moving blood between the heart and the lungs, and the systemic circulation, which delivers oxygenated blood to the rest of the body.
Main Components and Functions of the Circulatory System-
The cardiovascular system includes three primary components: the heart, blood vessels, and blood. Each performs a critical role: the heart as the pump, blood vessels as the conduits, and blood as the transport medium carrying vital elements such as oxygen, hormones, and nutrients.
The functions of the circulatory system encompass the delivery of essential substances to the body's cells and the transportation of waste products to organs that can expel them from the body. Together, these elements and their seamless coordination are vital to the survival of the individual.
What is the difference between covalent and ionic bonds?
A. Ionic bonds are stronger than covalent bonds.
B. Electrons are transferred to form covalent bonds.
C. Electrons are shared to form ionic bonds.
D. Covalent bonds are stronger than ionic bonds.
Answer:
Covalent bonds are stronger than ionic bonds
Explanation:
Ionic bonds are formed by the transfer of electrons from the electropositive element to the electronegative element. Covalent bonds are formed by the mutual sharing of electrons.
Covalent bonds have high bond dissociation energy as compared to the ionic bond. The overlapping of molecular orbital is bigger in case of covalent bond as compared with ionic bonds. Hence, covalents bonds are difficult to break and stronger than ionic bonds.
Thus, the correct answer is option (D).
Covalent and ionic bonds differ in how electrons are shared or transferred. In covalent bonds, electrons are shared between atoms, whereas in ionic bonds, electrons are transferred from one atom to another.
Explanation:The difference between covalent and ionic bonds lies in how electrons are shared or transferred. In a covalent bond, electrons are shared between atoms. This occurs when atoms have similar electronegativities and there is a mutual attraction for the shared electrons. On the other hand, an ionic bond forms when electrons are transferred from one atom to another, resulting in positively and negatively charged ions that attract each other.
For example, let's consider the formation of a covalent bond in a molecule of water (H2O). The oxygen atom has a stronger pull on electrons, so it attracts the shared electrons more than the hydrogen atoms. This leads to a slightly negative charge on the oxygen atom and slightly positive charges on the hydrogen atoms.
In contrast, imagine the formation of an ionic bond between sodium (Na) and chlorine (Cl) to form sodium chloride (NaCl). Sodium has a tendency to lose an electron, resulting in a positively charged sodium ion (Na+), while chlorine has a tendency to gain an electron, forming a negatively charged chloride ion (Cl-). These oppositely charged ions are then attracted to each other, forming an ionic bond.

Explanation:
Answer: D. Biological magnification
Explanation:
A food chain is a linear sequence of transfer of food and energy when one organism is consumed by another organism. The transmission of food and energy takes place from the lower trophic level to higher trophic levels when organisms of the lower trophic level are consumed by the organisms of higher trophic levels.
Biological magnification is a phenomena in which a toxic material or pollutant enters into the food chain. The material remains undigested in the body of the organisms and causes detrimental effects. The organisms at the highest trophic levels decline in number due to the increase in concentration of the toxic at the higher level as they consume organisms of the lower trophic levels.
According to the given situation, biological magnification is the correct option because here the amounts of pollution at the higher trophic levels is the greatest as compared to the lower trophic levels.
1. Which of the following supports the theory that all modern human populations are descended from a single ancestral population that emerged in Africa?a. Comparative molecular studies trace our earliest genetic material to Africa.b. Stone tools found in sediments coeval with the earliest H. ergaster (just under two million years ago) are essentially identical with those made by the first stone toolmakers many hundreds of thousands of years before.c. H. erectus evolved in eastern Asia at quite an early date and one branch of the species migrated back to Olduvai in Africa.No human fossils are associated with the first stone tools known, from sites in \Kenya and Ethiopia.
Answer:
a. Comparative molecular studies trace our earliest genetic material to Africa
Explanation:
With the development of the genetics we have been able to come to new findings or confirm some suspicions when it comes to the origin of the humans. The genetic analyses of the human DNA and the other hominids that have died out, as well as out closest ''cousins'' in the animal kingdom, have shown that the earliest human ancestors have evolved in Africa. Over time, as the conditions allowed it, the hominids started to migrate out of Africa and gradually started to settle all around the planet.
The theory that all modern human populations descended from a single ancestral population in Africa is best supported by comparative molecular studies that trace our earliest genetic material back to Africa. Stone tool findings and the migration of H. erectus do not provide direct evidence of this theory.
Explanation:The hypothesis that all modern humans share a common ancestry from Africa is most strongly supported by comparative molecular studies that trace our earliest genetic material back to Africa. Evolutionary biologists use molecular biology tools to compare DNA sequences between different populations and species, which has allowed them to trace back the origin of humans to a single ancestral population in Africa. This is known as the 'Out of Africa' theory. The other options like stone tools found or the evolution of H. erectus in Eastern Asia, while crucial pieces in human evolution history, doesn't directly support the fact that all modern humans share a common ancestor from Africa.

How many kilocalories of energy would you expect a person in contemporary England to consume daily (including food, transportation, household use, etc.)?
Answer:
Explanation:
The calories you eat are technically kilocalories, so typically you eat a couple thousand a day
Answer:
That person would need thousands of calories a day.
Explanation:
The ideal amount of daily calories is different for each individual. Factors such as height, age, gender, muscle mass, daily activities, etc. influence the basal caloric expenditure of the organism. However, the number of calories a person needs to consume per day is always measured over one thousand calories. That is, no matter if you live in England or Africa, that person will need to consume thousands of calories a day to stay healthy. Usually the ideal amount of calories a person in normal health should consume is around 2000 - 2200 calories per day.

A molecule of urea travels from the renal artery to the kidneys where it isn't reabsorbed during filtration and continues as part of the urine. The urine moves from the kidney to the bladder through the ureters and exits the body via the urethra during micturition.
Explanation:A molecule of urea in the body starts in the blood and reaches the kidneys via the renal artery. The urea is then filtered through the glomerulus to form a filtrate, which enters the renal tubules for reabsorption and secretion processes. Urea, a waste product, isn't reabsorbed but continues as part of the urine. The urine travels from the kidney to the urinary bladder via ureters. Upon micturition, urine holding urea is then transported through the urethra, which in a female is shorter compared to a male, and exits the body.

Why is nitrogen important to all living things?
Answer:
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
Hope This Helps ; )
Explanation:
Nitrogen is vital for forming proteins, nucleic acids, and chlorophyll, but must be fixed from atmospheric N2 into usable forms through nitrogen fixation, a key part of the nitrogen cycle.
Nitrogen is essential to all living things as it is a key component of amino acids, proteins, and nucleic acids like DNA and RNA. Although atmospheric nitrogen (N2) is abundant, making up about 78% of the Earth's atmosphere, it is in a form that is not directly usable by eukaryotic organisms. Through a process known as nitrogen fixation, certain microorganisms convert this inert nitrogen into ammonia (NH3), which can then be assimilated into organic molecules. Plants and other photoautotrophs require nitrogen to synthesize chlorophyll, which is crucial for photosynthesis. The nitrogen cycle is a complex series of processes that recycles nitrogen through various forms in the ecosystem, ensuring its availability for all forms of life.

-Photosynthesis makes the glucose that is used in cellular respiration to make ATP
-The glucose is then turned back into carbon dioxide, which is used in photosynthesis
-While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

Which of these describes the main influence of jet streams on weather patterns? A. Weather systems, such as storms, steer along jet streams. B. Jet streams cause hurricanes to form over warm tropical waters. C. Surface ocean water is pushed toward land by jet streams. D. Jet streams separate high pressure systems from low pressure systems.
Answer:
Actually the correct answer is Weather systems, such as storms, steer along jet streams. because...
Explanation: Jet streams push air masses and can influence and affect weather patterns.
Answer:
Weather systems, such as storms, steer along jet streams.
Explanation:
Jet streams are strong winds that occur in relatively narrow bands. They are found in the upper levels of the atmosphere, around 11,000 meters above the Earth's surface. They influence weather patterns because they steer weather systems such as storms.
Why Is It Important To Avoid Applying Too Much Nitrogen Fertilizer?
Answer:
Under the soil, root growth often suffers. Nitrogen fertilizers can increase the salt content of soil, which can cause plants to get dehydrated. ... You will be more likely to notice damage from excess nitrogen to your plants, if the weather is drier than normal.

Explanation:
Answer:
too much nitrogen in surface runoff can cause algae to overgrow
Explanation:
Nitrogen fertilizers used in large-scale agriculture could leave a legacy of pollution that would persist for decades in soil and groundwater, scientists in France and Canada warned, which published a study in the National Academy of Sciences magazine, " PNAS ". According to these scientists, the excess of these fertilizers in the environment has been linked to contaminated drinking water and can cause the rapid growth of algae that compromise aquatic ecosystems and coastal marine life.
What kind(s) of cells can develop from pluripotent stem cells?
A. Any cells of the human body, but not cells of the placenta
B. Any cells of the human body or the placenta
C. Only cells that are identical to the original stem cell
D. Only cells that are closely related to the original stem cell
ONLY ANSWER IF YOU KNOW ITS CORRECT!
Answer: B. Any cells of the human body or placenta.
Explanation:
All types of cells in the human body can develop from pluripotent stem cells. Embryonic stem cells are also considered pluripotent.
Any cells of the human body, but not cells of the placenta can develop from pluripotent stem cells. Therefore, option A is correct.
Pluripotent stem cells have the ability to differentiate into any cell type found in the human body. This includes cells of various tissue types such as nerve cells, muscle cells, blood cells, and more. However, pluripotent stem cells cannot give rise to cells of the placenta.
These cells are typically derived from embryos, and their potential to differentiate into a wide range of cell types makes them valuable in regenerative medicine and research.

Studies in which the suprachiasmatic nucleus (SCN) was surgically removed from laboratory mammals demonstrated that the SCN is required for circadian rhythms. But these studies did not reveal whether circadian rhythms originate in the SCN. To answer this question, researchers performed an SCN transplant experiment on wild-type and mutant hamsters (Mesocricetus auratus). For wild-type hamsters, the period between cyclic peaks in activity is 24 hours in the absence of external cues. Hamsters homozygous for the τ (tau) mutation have a period lasting only about 20 hours. In this exercise, you will evaluate the design of this experiment and propose additional experiments to gain further insight. The researchers surgically removed the SCN from wild-type and τ hamsters. Several weeks later, each of these hamsters received a transplant of an SCN from a hamster of the opposite genotype. These transplants restored rhythmic activity in 80% of the hamsters. For hamsters in which an SCN transplant restored a circadian rhythm, the researchers measured the circadian period. The results are shown in the graph. Each red line represents the change in the measured period for an individual hamster. Part A - Understanding the experimental design In a controlled experiment, researchers manipulate one variable at a time. What was the experimental variable in this study?
