How do cells know how to develop within a multicellular organism?
a. they all develop in exactly the same way.
b. they receive instructions in their dna.
c. they follow a pattern that comes from outside the cell.
d. they learn as they go along.

The correct answer is option b. They receive instructions in their DNA.

The DNA (deoxyribonucleic acid) or the genes present in the cell guides the fate of the cells during the process of cellular differentiation in the embryonic life of the multicellular organism. The signaling molecule change the genetic expression changes, by which the cells are differentiated.

the answer is tropical areas. the tropical areas obtain more

radiant energy from the sun than they lose to space through terrestrial

radiation, and vice versa for polar areas. earth has an energy remaining in the

tropics and an energy scarcity for the polar areas.
