A multicellular organism typically begins as a single cell, and then many cell divisions occur to generate the cells of the adult organism. However, these cells are not identical to the original cell, and they are not identical to one another.

What is the most significant cause of cell differentiation in a multicellular organism?

A.
differences in the number of chromosomes per cell
B.
differences in the genetic code used by different cells
C.
differences in the DNA that is copied and distributed among the cells
D.
differences in gene regulation and gene expression among the cells

D

Explanation:

Difference in cell regulation and cell expression. This is embedded in chromosomes which is the blue print of the organism. The chromosomes is like the house plan when you building a house.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
