Dahasolnce [82]2 years ago

Answer:

Some body parts, for example, such as muscles, red blood cells, nails, skin, and hair, wear out and/or they die, and therefore they are constantly replaced. To replace the worn out parts and dead parts, there is need for cell division.  Other body parts last longer. For example, the liver will last as long as a person lives, and in fact liver failure is one way a person will die. Liver cells are normally not replaced, and therefore there is normally no cell division in the liver. Cell division in these body parts would simply make them bigger and bigger and that may result in illness or even death. In fact, cancer cells are cells that should not be dividing but they continue to divide non-stop because something went wrong.

marshall27 [118]

Answer:

The options

a. sympatric speciation; vicariance

b. allopatric speciation; vicariance

c. sympatric speciation; dispersal

d. allopatric speciation; dispersal

The CORRECT ANSWER IS d.

d. allopatric speciation; dispersal

Explanation:

Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).

Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.

In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
