These diagrams show a variety of cells from the same organism. How can cells from the same organism have such different shapes and functions?

• As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity.

• Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.

• During differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.

• During differentiation, different types of cells produce proteins which destroy the nonactive DNA, leading to cell specialization.

Which statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration?

• The products of photosynthesis serve as the reactants in cellular respiration to provide chemical energy.

• The products of photosynthesis combine with the reactants in cellular respiration to remove ATP from cells.

• The products of photosynthesis inhibit the reactants in cellular respiration in the presence of light.

• The products of photosynthesis change the structure of the reactants in cellular respiration in the presence of light.
