During the Carboniferous period, plants and animals grew very large due to high concentration of A. oxygen in the atmosphere. B. nitrogen in the atmosphere. C. carbon dioxide in the oceans. D. argon in the oceans .
Answer:
Option A, oxygen in the atmosphere
Explanation:
The highest level of oxygen reached during this phase of the geological cycle of earth. The oxygen level in Carboniferous period accounted for 35% as compared to 21% of oxygen in the atmosphere in present time.
Due to high oxygen content, the giant and wide varieties of terrestrial animal and plant species evolved. For example – size of insects and carwlies increased, plant became extremely giant, increase in number of tree ferns etc.
During the Carboniferous period, plants and animals grew very large due to high concentration of oxygen in the atmosphere and the correct option is option A.
The Carboniferous period is a geologic period and system that spans from 358.9 to 298.9 million years ago in the Paleozoic Era. It is named after the Latin word "carbo", meaning coal, as this period saw the formation of large coal deposits. The Carboniferous period is also known as the "Age of Amphibians" due to the dominance of these animals on land.
During the Carboniferous period, the Earth's continents were slowly coming together to form the supercontinent Pangea. This led to a warm and humid climate, which was ideal for the growth of swamp forests. These forests were home to a wide variety of plants and animals, including amphibians, reptiles, and insects.
Thus, the ideal selection is option A.

A.
0.3 m/s
B.
3.0 m/s
C.
9.0 m/s
D.
30.0 m/s
The formula for speed is: v=x/t, where v is speed, x is distance, and t is time.
v=27/9
v=3
B) 3 m/s
Hope this helps!!
Final answer:
The dog's speed is calculated using the formula speed = distance/time, which gives us a speed of 3.0 m/s for the interval mentioned.
Explanation:
Speed is calculated as distance divided by time. In this case, the dog ran 27 meters in 9 seconds. Therefore, the speed is 27m / 9s = 3m/s.
To calculate the dog's speed for the interval during which it ran 27 meters in 9 seconds, we use the formula for speed which is speed = distance/time. In this case, the distance is 27 meters and the time is 9 seconds.
Speed = 27 meters / 9 seconds = 3 meters/second
Therefore, the dog’s speed for this interval of the game of fetch is 3.0 m/s, which corresponds to option B.
Describe how the functions of proteins differ from the functions of carbohydrates ( 150 words)
Component molecules assemble in different ways to form the basic units of carbs and protein. In carbs, that basic unit is a saccharide, another word for sugar. Monosaccharides are single-unit sugars, the simplest carbs. These can link up with each other to form two-unit sugars -- also known as disaccharides -- or polysaccharides, which can be hundreds of units in length. In contrast, amino acids are the basic units of proteins. Approximately 20 types of amino acids act as your body's primary protein building blocks. They can assemble in very complex ways to form helices, pleated sheets, globules or even multi-unit protein structures.
While protein's primary role is structural, carbohydrates primarily serve as an energy source. In fact, glucose -- one of the simplest carbohydrates -- is your body's preferred energy currency. Whenever your body derives energy from protein because of a low supply in carbs, protein components must undergo a number of biochemical changes to be useful in energy production. Proteins serve above all as your body's building blocks. Every cell needs them for structure, but they also play important roles as molecule transporters, hormones, disease-fighting agents and enzymes Some carbs -- namely fiber -- are important for bowel health and waste elimination
Carbohydrates are the major source of energy to our body while proteins are the building blocks of our body.
How the functions of proteins differ from the functions of carbohydrates?The main source of energy of our body are carbohydrates on the other hand, proteins act as the building blocks of our body. Carbohydrates and proteins are important macromolecules. Carbohydrates are composed of simple sugars and proteins are composed of amino acids.
Carbon, hydrogen and oxygen are the main elements of carbohydrates and proteins contain Carbon, hydrogen and oxygen, Sulphur or Nitrogen. Carbohydrates are broken down to make glucose to fuel the body and all enzymes, many hormones and many neurotransmitters are proteins.
As a result, this is how functions of proteins differ from the functions of carbohydrates.

The Cretaceous-Paleogene was a mass extinction event in which nearly every single large, land-dwelling dinosaur went extinct. Which of the following did not result from this extinction event?
A.
Diverse species of animals began to evolve.
B.
Meteorites struck the region that Mexico now occupies.
C.
Clouds of dust and gas billowed into Earth's atmosphere.
D.
Ecological niches were left empty but with the potential to be filled.
Answer:
B. Meteorites struck the region that Mexico now occupies
Explanation:
The meteorite or comet that struck in the area where Mexico is located in the present is not part of the consequences of the extinctions event. The reason why it is not part of the consequences is that it is the factor that caused the consequences, so it can not be both the thing that caused something and also the consequence of it. This meteorite or comet managed to create such a huge explosion, that it managed to wipe out pretty much all large and medium sized land dwelling animals. And that was not caused only by the explosion itself, but also because it drastically changed the climate with the huge amounts of ashes and dust released into the atmosphere, as well as the triggering of the volcanoes around the world. This mass extinction though opened up the gates for the evolution of the mammals which soon became the dominant animals on the planet.
The Cretaceous-Paleogene mass extinction resulted in the extinction of large, land-dwelling dinosaurs. It led to the evolution of diverse species and left empty ecological niches to be filled in the future.
Explanation:The Cretaceous-Paleogene mass extinction was caused by a cataclysmic impact of a large meteorite, or asteroid, off the coast of what is now the Yucatán Peninsula. This impact led to the extinction of nearly every single large, land-dwelling dinosaur. The extinction event resulted in diverse species of animals evolving and ecological niches being left empty but with the potential to be filled. However, meteorites striking the region that Mexico now occupies and clouds of dust and gas billowing into Earth's atmosphere were not direct results of this extinction event.

I just took this on my cumulative review test!
Good luck to the future people taking this:)
Answer:
Options (1) and (2)
Explanation:
The atmosphere is defined as the gaseous envelope that surrounds the earth. It is comprised of various gases which are found to be present at a certain amount, and this amount can also be increased or decreased depending on the processes and activities that take place on the earth's surface.
The atmosphere is helpful because it protects the lives present on earth from the harmful incoming UV radiations emitted from the sun. It also protects the water present on earth from getting evaporated into the atmosphere.
Thus, the correct answers are options (1) and (2).
Most aquatic organisms can survive only within a specific pH range. An increase in the number of hydrogen ions (H+) in a lake with many aquatic organisms would cause
A.
the acidity of the lake to decrease.
B.
no change in the pH of the lake.
C.
the water in the lake to evaporate.
D.
the acidity of the lake to increase.
Answer:
D. The acidity of the lake to increase
Explanation:
Fun fact: did you know tomatoes are acidic because they have a pH value lower than 7?
Answer:
Option D, the acidity of the lake to increase.
Explanation:
The increase of hydrogen ion in lake water increases the acidity of the lake. The acidity of lake is associated with pH of the water which depends on the hydrogen ions concentration as established by the equation given below –
pH[tex]= - log H^+\\[/tex]
The hydrogen ion concentration is directly proportional to the acidity of the lake water. Thus, higher the H+ ion concentration, the higher will be the acidity of water.
Why is the top layer of the ocean the warmest?
The top layer of the ocean is the warmest because it absorbs most of the sunlight, resulting in a less dense water that stays at the surface. This layer, mixed by winds and currents, is called the mixed layer. Below this, temperature decreases rapidly in the thermocline, and deep layers receive no sunlight, remaining cold and stable.
Explanation:The top layer of the ocean is the warmest because it is most directly affected by the sun's energy. The sunlight efficiently heats the ocean's surface, resulting in a warm, less dense layer of water. This layer is referred to as the mixed layer, which has a uniform temperature due to the mixing effects of surface winds, waves, and currents. Beneath this mixed layer is the thermocline, a zone where the temperature drops rapidly with increased depth. Deeper parts of the ocean are substantially cooler because sunlight cannot reach them, and water here has minimal interaction with atmospheric temperatures.
The density of seawater, which is determined by its temperature and salinity, contributes to the ocean's stratification, with denser (colder and saltier) water lying below lighter (warmer and less salty) water. Human activities have increased the temperature at the ocean's surface, and satellite observations have confirmed the expansion of low-productivity areas in the ocean due to reduced vertical mixing and nutrient supply caused by this increased stratification.
Furthermore, the ocean absorbs a significant amount of the Earth's heat, with most of it concentrated near the surface. This is due to the ocean's high specific heat capacity, which allows it to absorb a lot of energy with only a small increase in temperature. Overall, the ocean's top layer remains the warmest due to a combination of sunlight absorption, wind-induced mixing, and the high heat capacity of water.

what structures inside plant cells help with photosynthesis?
Answer:
Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
Final answer:
Chloroplasts, with their chlorophyll and other pigments arranged in an antenna complex, are the main structures that facilitate photosynthesis in plant cells. The process also involves the stomata for gas exchange and the mesophyll layer which houses the chloroplasts.
Explanation:
The structures inside plant cells that help with photosynthesis are called chloroplasts. These chloroplasts contain chlorophyll, the pigment responsible for the green color of plants, and are the sites where photosynthesis occurs. Chloroplasts consist of a double membrane enclosing an inner fluid called the stroma, which contains coin-like thylakoids stacked in grana. The thylakoids have a specialized membrane that embeds the chlorophyll and accessory pigments, organized in an antenna complex that captures solar energy and transfers it to a reaction center. Additionally, the process of photosynthesis in leaves involves cellular structures such as stomata regulated by guard cells for gas exchange, and the mesophyll layer where the chloroplasts are largely located.

why do some researchers prefer to use embryonic stem cells in medical research
Answer:
Cell therapies would use stem cells, or cells grown from stem cells, to replace or rejuvenate damaged tissue. Scientists also want to use stem cells to understand disease and find drugs that might treat it. Embryonic stem cells could be used to make more specialized tissues that have been lost to disease and injury.
Researcher's preference for embryonic stem cells is attributed to their totipotency and capacity to differentiate into any cell type, which is key in medical research and therapy development. Cloning techniques can create tissue matches to avoid transplant rejection. Nevertheless, ethical issues arise from the destruction of embryos in the process.
Researchers prefer to use embryonic stem cells in medical research due to their unique characteristics. These stem cells are totipotent, which means they have the potential to develop into any type of cell in the body, leading to significant medical applications such as the study of human embryonic development and the creation of therapies for replacing damaged tissue. Cloning techniques that employ embryonic stem cells may also enable the growth of tissue matching the donor DNA exactly, eliminating issues of tissue rejection in transplants.
Moreover, they can be grown in culture, allowing researchers to harvest and amplify these cells. Significant progress has been made in the field; for example, scientists like Freda Miller and Elaine Fuchs discovered stem cells in skin that assist in its repair, potentially aiding treatments for skin diseases and nerve damage. However, this field is accompanied by ethical concerns due to the destruction of embryos during cell harvesting, leading to moral, religious, and philosophical objections.
