So the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set
Answer:
a fuel for cellular respiration and a starting material for making other organic molecules.
Explanation:
Plants have the ability to produce sugars by the process of photosynthesis. Plants can convert the inorganic CO2 from the air into the organic nutrients such as sugars. Plants store sugars so that they can serve as a source of ATP for the cells as and when required. The sugars enter the process of cellular respiration and are oxidized into CO2 and H2O. In addition, the energy of chemical bonds of the sugars is used to form ATP molecules.
Plants also use sugars to synthesize other organic molecules. For example, several intermediates of Kreb's cycle can serve as precursors for the synthesis of amino acids. Amino acids are joined together to form different proteins.
Well, carbohydrates burn and release energy. Nucleic acids give identity (like DNA, RNA). Lipids also give energy, but it's more difficult (they must be first turned into carbohydrates first). Proteins are building blocks for the cells.
Now, knowing all of this should make it easy to choose the correct answer :)
B). A population changes in response to a change in the environment.
