When a population is split into smaller groups, why do these groups develop different traits?

a. separating the two groups decreases the chance that the two groups will diverge

b. traits that form in one group from evolutionary forces quickly spread through both populations

c. forces like natural selection and genetic drift affect the genes of the two subgroups differently

d. gene flow is increased in the two subgroups that are formed

C. Forces like natural selection and genetic drift affect the genes of the two subgroups diffidently.

Explanation:

For example, a group of finches separate do to something out of the blue. Over time, one group may evolve and develop traits that make them different from the original group, like larger or smaller beaks. The genetic drift comes into play since the genes that affect the physical and mental behaviors are being created or switched around.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
