E)All of these choices are correct.

Question

Quizplus · Accepted Answer

All of these choices are correct. Differentiation in complex multicellular organisms involves a combination of genetic, environmental, and cellular factors that ultimately result in cells acquiring different functions and fates. Different combinations of genes are activated and repressed in different cells, which leads to the expression of different proteins in different cells. These processes are influenced by signals from the environment, which can vary depending on the location of the cell within the organism. Additionally, cells in different tissues and organs acquire different fates during development, which further contributes to cellular diversity in complex organisms.
