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."
Human evolution and natural selection reduce susceptibility of disease. A simple explanation would be saying that the life forms that are not immune to the disease pass away, then the ones that are immune or survive genetically give this trait to their offsprings, leaving only life forms that are immune. This does not occur so easily and is a long process, but it is a simple explanation.
