Answer:
Living organisms often contain trace amounts of several elements, but the most abundant ones are oxygen, carbon, hydrogen, nitrogen, calcium and phosphorus.
Explanation:
The products of photosynthesis is to gain energy and build compounds, like glucose from carbon dioxide, making it anabolic
The reactants of cellular respiration are catabolic, and that refers to the breaking down of compounds, which releases energy.
The relationship is that they're complex compounds that consist of materials coming from essential processes in the cell.
Answer: more out of us
Explanation:well we breath 21 % of oxygen so that means their is more out of us
Evoultion is the change of the allele frequencies and the inherited traits of a population over time.
The idea of evolution is that the species change over time. The proposed mechanism of evolution is natural selection. Natural selection favors inheritable trait, suitable for survival and reproduction. Organisms with such traits will tend to leave more offspring than others, and thus will evolve over time.
