Choices are:
A. eliminating unnecessary genes
B. healing wounds effectively
C. replacing lost cells, such as shed skin cells
D. preventing communication among cells
Answer:
The answers are letters B and C.
Explanation:
"Multicellular organisms" are those organisms with many cells. Examples of these are kelp and Volvox.
In order for multicellular organisms to grow, they have to undergo a process called "mitosis." This is a type of cell division which allows the number of chromosomes to be maintained (such as the parent nucleus) in the resultant cells (identical cells).
The division aids in the organism's growth and repair, thus wounds are healed effectively. It also allows the replacement of lost cells, such as shed skin cells because the organism can regenerate cells when the need arises.
In contrast to unicellular organisms which uss cell division for reproduction, multicellular organism use cell division for "healing and repair" as well as "regeneration."
