Stem cells can form many kinds of cells. in contrast, most body cells cannot form different types of cells. for example, skin cells can only make skin cells and nerve cells can only make nerve cells. which statement best explains why skin cells will never become nerve cells?

a.) each type of cell receives a different message from the central dna, which is stored in dna cells.

b.) each type of cell has only the part of the dna necessary for making that type of cell.

c.) each cell type is determined by messages sent from the brain, which directs development.

d.) both types of cells have the same dna, bt the cells have different genes turned on resulting in a different type of cell.

What is the name of the type of cell division that occurs in the prokaryotic cell cycle

The equation shows cellular respiration. during cellular respiration, glucose combines with oxygen to form carbon dioxide, water, and atp. what happens to the energy in the bonds in glucose? the energy is transferred to oxygen. the energy is transferred to carbon dioxide. the energy is transferred to water. the energy is transferred to atp.
