Answer:

The genetic diversity of new population decreased and this is an example of genetic drift.  

Explanation:

Founders effect is the case of genetic diversity which occurs when a small number of individual from a larger population of species gets isolated from the larger population and occupy a different habitat. In the smaller population, the genetic diversity reduces because they lost many allele which was present in the larger population.

Here a small number of individuals from mainland species moved to the islands of Galapagos therefore these individuals would not be having the total gene pool that was present in the large population of mainland species.  

So the genetic diversity of the new population of finches on the Galapagos  must be decreased concerning the population on the mainland and this is an example of genetic drift(founder's effect).

when a person suffers a stroke, it is initially caused by damage to the___ a) circulatory system b) nervous system c)pulmonary s
Makovka662 [10]

Answer:

The correct answer would be a) circulatory system.

A stroke is primarily caused due to reduced or interrupted supply of blood to the brain.

The blood supply is usually reduced as a result of blockage or bursting of an artery carrying blood to the brain.

Consequently, the brain cells experience a lack of oxygen and nutrients due to which they begin to die.

Thus, stroke is initially caused by damage to the circulatory system.
