A small group of squirrels gets separated from the rest of the population due to a large flood. These squirrels, now confined to this new island, begin to start a new population. This is an example of which of the following?

a. bottleneck
b. mutation
c. founder effect
d. None of these examples are correct.

c. founder effect

Explanation:

The founder effect occurs when there is a loss or reduction of genetic variation when a new population is produced or established by a few number of individuals from a large population. In other words, a new colony is formed from a large population. This could result to differences in phenotype ad genotype of the new population from the original population.

The gene pool of the new population is also affected. The small group of squirrels that separated from the the large population during the flood to form a new population, is an example of founder effect.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
