Which of these statements accurately describes the energy conversion that occurs in cellular respiration?
A) ATP is converted into thermal energy.
B) Chemical energy is converted into ATP.
C) Heat energy is converted into chemical energy.
D) Light energy is converted into kinetic energy into the products.
Chemical energy is converted into ATP in cellular respiration. Therefore, option B is correct.
What is cellular respiration?The process of cellular respiration involves the oxidation of biological fuels in the presence of an inorganic electron acceptor, like oxygen, to generate significant amounts of energy that are used to power the major creation of ATP.
Both the cytosol and mitochondria of cells participate in cellular respiration. While pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation take place in the mitochondrion, glycolysis happens in the cytosol.
The primary goal of cellular respiration is the production of energy, even though it can also result in the production of other substances like lactic acid or carbon dioxide. Every biological process requires energy. Therefore, option B is correct.

Some factories have started using large tanks of bacteria to remove carbon dioxide from the atmosphere. As more factories start to do this, the amount of carbon dioxide in the atmosphere could decrease over time. If this happens, and if energy coming from the sun and the amount of carbon dioxide being put into the atmosphere otherwise stay the same, what would happen to the total amount of energy in the Earth system and to global average temperature? If there is a change, explain how that change would happen.
Answer:
There would be less carbon dioxide in the atmosphere if more factories started using bacteria to capture carbon dioxide.
Explanation:
More energy reaches the Earth system than exited as combustion introduced carbon dioxide to the atmosphere, so the total amount of energy in the system increased.
Fewer CO₂ in the atmosphere will come from fewer factories using microbes to absorb CO₂. Greater energy in Earth's system as CO₂is released into the atmosphere.
Earth system:When combustion releases CO₂ into the atmosphere, greater energy enters the Earth system than exits, leading to an increase in the overall amount of energy in the system.
There'd be fewer CO₂ in the atmosphere if more firms began to use microbes to trap CO₂. When the amount of carbon dioxide in the atmosphere declines, the Earth's system receives less energy than it expels.Outgoing energy is sent back to the surface to be absorbed by CO₂. As a result, when less energy is redirected, greater energy leaves the system, resulting in less energy in the Earth's system. Since the surface absorbs less energy, global average temperatures would drop.Find out more about the Earth system here:

difference between parallel venation and reticulate venation
this is where you can get
The difference between parallel venation and reticulate venation is in parallel venation, the vein of the leaf blade is in a parallel pattern, and in reticulate the vein of the leaf blade is a net or web-like structure.
What is venation?Venation is the pattern of veins present in the leaves. There are different patterns of veins present in the leaves, parallel venation, for example, banana leaf, and reticulate venation, for example, papaya leaf.
Thus, In contrast to reticulate venation, where the vein of the leaf blade is arranged in a net-like pattern, parallel venation has the vein of the leaf blade arranged in a parallel pattern.

Plants that reproduce sexually generate seeds. These seeds are often dispersed away from the parent, either through wind , animals , or water. Look at the seed shown in this image of bullrush plants. What form of dispersal do you think it uses, and why ?
Can anyone help me in this question
Help!!!
Answer:
wind/water either one.
Explanation:
It can reproduce from rhizomes or seed and uses the wind and water to disperse its seeds.
Based on the appearance of the seed shown in the image of bullrush plants, it appears that these seeds are dispersed by wind.
What are different form of seed dispersal?Seed dispersal is the movement of seeds away from the parent plant, allowing them to establish in new locations and increase the chances of survival and reproduction. There are several forms of seed dispersal, including:
Wind dispersal: Seeds with feathery structures or plumes, such as dandelions, are carried by the wind.Animal dispersal: Animals can carry seeds away from the parent plant in their fur or digestive systems, such as berries eaten by birds.Explosive dispersal: Some seeds are expelled from their pods with great force, such as in the case of squirting cucumbers.Water dispersal: Seeds with waterproof coats can float on water and be carried long distances, as seen in coconut palms.Biotic dispersal: Seeds can also be dispersed by other living organisms, such as ants that carry seeds to their nests and bury them there.Learn more about seed dispersal, here:

What is the importance of neutral variation in evolution?
A trait that is neutral in one environment may be advantageous in another.
It is usually removed from the population by natural selection due to its deleterious phenotypes in the environment.
A trait that is neutral will most likely be removed from the gene pool.
It will cause for a population to risk decline and extinction.
Answer:
A trait that is neutral in one environment may be advantageous in another.
Explanation:
Neutral variation refers to the variation (either genetic or phenotypic variation) which is unaffected by natural selection. Neutral variation is known to increase genetic variation, which is a prerequisite to evolutionary change. An allele may be neutral in one environment and beneficial (or deleterious) in another. In consequence, neutral variation in one environment may increase the response to selection in different environmental conditions.
