Why do some organisms reproduce asexually
Answer:
Some organism reproduce by asexual reproduction because it does not requires much energy and is very convenient.
This type of reproduction does not requires two parent. They do not involve the fusion of male and female gamete.
The offspring produced by this process are same and it does not requires much time to produce offspring.
There is no variation in the offspring and the stability of organism produced by asexual reproduction is less as compared to that of sexual.
Final answer:
Organisms reproduce asexually to rapidly produce offspring without needing a mate, resulting in a quickly growing population of genetically identical individuals, which can be beneficial in stable environments but a disadvantage in changing ones.
Explanation:
Some organisms reproduce asexually because this method of reproduction can be very quick and does not require the meeting of male and female organisms. Asexual reproduction allows for the rapid growth of a population since every individual is capable of reproduction, leading to advantages in certain environmental conditions. Asexual reproduction often results in offspring that are exact genetic clones of the parent, which can be beneficial if the parent's traits are well suited to the environment.
However, it also means that all offspring carry the same genetic vulnerabilities, which can be a disadvantage in changing or unpredictable environments. Sexual reproduction introduces genetic variation which can be advantageous for populations in variable environments, as it enhances adaptability and increases the chance of survival against diseases and environmental changes.

in which position are the earth, moon, and sun during a new moon?
A. Moon is between the sun and earth
B. Earth is between the sun and moon
C. Sun is between Earth and the moon
D. Moon is to the side of earth and the sun
Please help!
Answer:
A. Moon is between the Sun and Earth
Explanation:
The new moon stage is the faze in which we can not see the Moon from Earth. In this stage, the Moon is lacking from the sky, or rather we can not see it because it is totally dark from the side that is facing the Earth. The reason for this is that the Moon is located between the Sun and the Earth. The Sun is making half of the Moon bright as it always does, but in this stage it is the half of the Moon that is facing the Sun, while the other half that is facing the Earth is totally dark as it doesn't receive any sunlight at that time.

In fruit flies the allele for long wings (L) is dominant and the allele for short wings (l) is recessive. What is the likely genotype of a fruit fly with short wings?
Either LL or Ll
Either Ll or ll
Only LL
Only ll
Answer:
The likely genotype of a fruit fly with short wings is Only ll.
Explanation:
There are two types of traits, Dominant and recessive. For a dominant trait only single copy of gene is sufficient for a phenotype to appear. So LL and Ll both will result in long wings. While in a recessive trait both copies should be identical for the phenotype to appear. only ll genotype will result in short wing fruit fly.
Answer:
Only ll
Explanation: Only ll is the answer to this test.
why should the number of each kind of atom be equal on both side of a chemical reaction
Answer:
Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical equation.
The number of each kind of atom must be equal on both sides of a chemical reaction to obey the law of conservation of mass, ensuring the mass of reactants equals the mass of products. This is represented in a balanced chemical equation.
In a closed system, no atoms are lost or gained during a chemical reaction, meaning the mass of the reactants must equal the mass of the products. This law is reflected in a balanced chemical equation, which is a statement of a chemical reaction with the number of each type of atom equalized for both the products and reactants. To achieve this balance, coefficients may be added in front of compounds to ensure the same number of atoms for each element on both sides of the equation. When correctly balanced, an equation shows that while the distribution of atoms may change, forming new compounds with new bonds, the absolute count of each type of atom remains constant before and after the reaction.

what are 5 major results of global climate change
Answer:
Change Will Continue Through This Century and Beyond
Global climate is projected to continue to change over this century and beyond. The magnitude of climate change beyond the next few decades depends primarily on the amount of heat-trapping gases emitted globally, and how sensitive the Earth’s climate is to those emissions.
Temperatures Will Continue to Rise
Because human-induced warming is superimposed on a naturally varying climate, the temperature rise has not been, and will not be, uniform or smooth across the country or over time.
Frost-free Season (and Growing Season) will Lengthen
The length of the frost-free season (and the corresponding growing season) has been increasing nationally since the 1980s, with the largest increases occurring in the western United States, affecting ecosystems and agriculture. Across the United States, the growing season is projected to continue to lengthen.
In a future in which heat-trapping gas emissions continue to grow, increases of a month or more in the lengths of the frost-free and growing seasons are projected across most of the U.S. by the end of the century, with slightly smaller increases in the northern Great Plains. The largest increases in the frost-free season (more than eight weeks) are projected for the western U.S., particularly in high elevation and coastal areas. The increases will be considerably smaller if heat-trapping gas emissions are reduced.
Changes in Precipitation Patterns
Average U.S. precipitation has increased since 1900, but some areas have had increases greater than the national average, and some areas have had decreases. More winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century.
Projections of future climate over the U.S. suggest that the recent trend towards increased heavy precipitation events will continue. This trend is projected to occur even in regions where total precipitation is expected to decrease, such as the Southwest.
More Droughts and Heat Waves
Droughts in the Southwest and heat waves (periods of abnormally hot weather lasting days to weeks) everywhere are projected to become more intense, and cold waves less intense everywhere.
Summer temperatures are projected to continue rising, and a reduction of soil moisture, which exacerbates heat waves, is projected for much of the western and central U.S. in summer. By the end of this century, what have been once-in-20-year extreme heat days (one-day events) are projected to occur every two or three years over most of the nation.
Hurricanes Will Become Stronger and More Intense
The intensity, frequency and duration of North Atlantic hurricanes, as well as the frequency of the strongest (Category 4 and 5) hurricanes, have all increased since the early 1980s. The relative contributions of human and natural causes to these increases are still uncertain. Hurricane-associated storm intensity and rainfall rates are projected to increase as the climate continues to warm.
Answer:
1. North and south poles are Melting (Slowly)
2. There is less rainfall in the Sahara Dessert
3. Sea levels rising
4. More floods due to risen sea levels
5. Hotter climates

Match each major blood vessel with the correct description
The aorta carries oxygen rich blood away from the heart.
The pulmonary artery transports deoxygenated blood from the heart to the lungs.
The inferior vena cava carries deoxygenated blood from the lower body to the heart.
The coronary artery branches from the aorta and provide oxygen to the heart muscles.
Answer & explanation:
Aorta - carries oxygen rich blood away from the heart.
The aorta contributes to the stability of blood flow by pumping oxygenated blood through the left ventricle.
Pulmonary artery - transports deoxygenated blood from the heart to the lungs.
The pulmonary artery originates from the right ventricle, it forks into the right and left pulmonary arteries.
Lower vena cava - carries deoxygenated blood from lower body to the heart.
This is the largest vein in the body, formed by the two iliac veins.
Coronary artery - branches from aorta and provide oxygen to heart muscles.
It also divides into left and right coronary arteries, where each carries oxygenated blood to different regions of the heart.
Where is frost wedging most likely to occur?
A. An arctic region where the ground is permanently frozen
B. A tropical region that experiences year-round warmth and heavy rain
C. A temperate region that experiences multiple freezes and thaws each year
D. A desert region that experiences high temperatures and dry conditions
Answer:
C. A temperate region that experiences multiple freezes and thaws each year
Explanation:
Frost wedging is a form of physical weathering which involves physical breaking of a rock.
Frost wedging occurs in areas where there is extreme cold and rainfall round the year.
The repeated freezing and thawing of water that is found in the cracks of rocks referred to as joints, pushes the rock to the breaking point.
Answer:
C
Explanation:
Water ‘expands’ when its temperatures go below 4 degrees centigrade. Therefore, ice is larger in volume compared to liquid water. Therefore, when water gets into the crevices and cracks of rock in the ground, the cyclic thawing and freezing of the water put stress on the rock/ground hence wearing it and forming and even bigger gorges.
Which process is BEST represented by the following chemical equation?
sugars + oxygen ----> carbon dioxide + water
Answer:
cellular respiration
Explanation:
This is when the body consumes and sugar and oxygen obtained from food and breathing to produce waste like water carbon dioxide when breathing out and sweat
Final answer:
The equation 'sugars + oxygen → carbon dioxide + water' represents cellular respiration, where glucose combines with oxygen to produce carbon dioxide, water, and energy. The reverse process, photosynthesis, is represented by 'carbon dioxide + water → glucose + oxygen', where plants convert CO₂ and H₂O into glucose and O₂ using sunlight.
Explanation:
The process best represented by the chemical equation 'sugars + oxygen → carbon dioxide + water' is cellular respiration. In this biological process, sugar such as glucose (C₆H₁₂O₆) reacts with oxygen (O₂) to produce carbon dioxide (CO₂), water (H₂O), and energy in the form of ATP. The balanced chemical equation for this reaction is C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O. Cellular respiration takes place in the mitochondria of cells and is essential for providing energy to maintain various cellular processes.
On the other hand, the chemical equation 'carbon dioxide + water → glucose + oxygen', which represents the process of photosynthesis, is the reverse of cellular respiration. During photosynthesis, green plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using energy from sunlight. The balanced equation for photosynthesis is written as 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O. Photosynthesis occurs in the chloroplasts of plant cells and contributes to the global oxygen supply while removing carbon dioxide from the atmosphere.
Which statements describe primary consumers? Check all that apply.
Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers. Level 3: Carnivores that eat herbivores are called secondary consumers. Level 4: Carnivores that eat other carnivores are called tertiary consumers.

What would happen if a plant could carry out photosynthesis, but not respiration?
Question 3 options:
It would have no food.
It could make food but not use it.
It would have too much water in its cells.
It would be unable to capture the energy in sunlight.
Answer:
answer is 1
it would have no food.
Explanation:
Photosynthesis also uses carbon dioxide faster than respiration produces it. Oxygen surplus is released into the air and unused glucose stored in the plant for later use. This is why plants are so important to human and other animals' survival. Without photosynthesis, we wouldn't have oxygen or food to stay alive.
Plant cells respire, just as animal cells do. If they stop respiring, they will die. Remember that respiration is not the same as breathing, so take care - plants do not breathe.
The study of plants is called botany. There are two types of plants and these are flowering plants and nonflowering plants.
The correct answer is A it would have no food.
What is respiration?The oxidation of the biomolecules to make the energy is called respiration.
Photosynthesis also uses carbon dioxide faster than respiration produces it. Oxygen surplus is released into the air and unused glucose is stored in the plant for later use.
This is why plants are so important to human and other animals' survival. Without photosynthesis, we wouldn't have oxygen or food to stay alive. Plant cells respire, just as animal cells do. If they stop respiring, they will die. Remember that respiration is not the same as breathing, so take care - plants do not breathe.
Hence, the correct answer is option A.

gardener purchased 20 full-grown pea plants. All 20 were the same genotype and had purple flowers. The gardener crossed two of these plants to get seeds for the next season. The seeds from the cross produced some plants with purple flowers and some with white flowers. The gardener learned that in pea plants the allele for purple flowers (P) is dominant of the allele for white flowers (p). What was the most likely genotype of the original 20 full-grown plants?
Answer:
maybe 75% of them were purple and 25% were white
Answer:
"Pp" is the most likely genotype of the original 20 full-grown plants
Explanation:
Given
All the 20 full-grown pea plants have purple flowers.
But when two plants out of these 20 are mated , then the seeds from the cross produced some plants with purple flowers and some with white flowers
This leads to a conclusion that though the 20 plants have purple color , they must be carrier of white color allele.
Thus, genotype of all the 20 pea plant species would be "Pp"
if two "Pp" genotype plants are crossed following offsprings are produced -
P p
P PP Pp
p Pp pp
Since "p" is a recessive allele , therefore when two recessive alleles are together they express their trait.
So, here in this case one out of four offspring is white in color.
Measures how much matter is present in a substance
Density. Density is the measurement of how much matter is in a substance
Mass is a measure of the amount of matter in a substance and is measured using a balance compared to a standard mass. In chemistry, the mole is used as the counting unit for particles in a substance, directly related to the mass via Avogadro's constant.
In chemistry, the mass of a substance can be measured using a balance, which is calibrated with a standard mass to ensure accurate measurements. For example, a kilogram of any substance, whether it is cotton balls or gold, has the same mass - the key is the comparison to the standard kilogram.
Matter is composed of atoms and molecules, and sometimes in chemistry, it is necessary to know the exact number of these particles in a sample. The counting unit for particles is the mole, defined as the amount of substance containing as many particles as there are atoms in exactly 12 grams of carbon-12 nuclide (¹2C). One mole of a substance corresponds to 6.02214 x 10^23 particles, known as Avogadro's constant.

Barnacles and whales have a commensalistic relationship in which barnacles benefit. What would most likely happen to the whale population if the barnacle population decreased?
Answer:
The whale population would grow at the same rate it used to. It would remain unaffected.
Explanation:
In the event of a decrease in the number of barnacles, the whale population shall remain unaffected.
This is because the relationship between the two is a commensalistic relationship, which means that the barnacle population that depends on the whale population does not in any way affect the whale population.
Thereby, the whales shall continue life as usual.

The scientists discover that all parts of plants are made of cell. Later, found that not only plants but all the living organism are made of cell. Cell perform all the basic necessities of life. The new cell arise from the pre existing cell.
Thus, the correct answer is option (D).
why is sexual reproduction important to the evolutionary proccess
Because of the genetic mutation, or the possibility of the offspring have a genetic disorder.
Answer:
These mutations are passed onto the next generation because the offspring are exact genetic clones of their parent. The genetic load of organisms and their populations will increase due to the addition of multiple deleterious mutations and decrease the overall reproductive success and fitness.
1. Nervous systems are required by animals to respond to stimuli and have complex senses such as taste, touch, sight, smell, or sound. These are carried by nerves to and from the brain and spinal cord. Of all major animal phyla, which does not have nerves?
A. Annelids
B. Porifera
C. Chordata
D. Cnidarians
B. Porifera. Porifera (sponges) is the only major phyla without nerves
Of all the major phyla the one that does not have a proper nervous system is the Porifera.
Answer: Option B
Explanation:
Any organism requires a nervous system to communicate between the activity center that is the brain. The nerves serve as communication vehicles between the brain and other parts of the body .
The phylum porifera majorly contains the sponges which do not have any nerve or brain cells . Their major communication between cell to cell is the circulation of water and the ejection of waste that occurs from the inside to the outside.
