Answer:

A) Remaining populations will have reduced genetic diversity

Explanation:

A random mating population allows for genetic diversity as each individual have equal chance of been mated to and it allows for perpetuation of frequently occurring genes.

For a small population the frequency of allele is mostly fix with virtually all loci having the same genotype because mating is within small individual and genes whose frequency is few will be drifted out of the population.

Hence, after the eruption due to a small random population diversity will be reduced as diversity occur more in a large random mating population.

Answer:

The correct answer is c) opsonins

Explanation:

Opsonization is a process in which proteins like antibodies and complement proteins called opsonins bind to the antigens and get it recognized by the phagocyted which destroys the antigen.

Especially when bacteria is having external capsule than it becomes difficult for phagocytes to attach to the capsular surface as the recognition molecule like membrane carbohydrate of antigen is concealed by capsule.

So to encounter this, antibodies like IgG and complement proteins like C3b attaches to the antigen and get it recognized and opsonized by the phagocytes like macrophages. This opsonization causes the destruction of antigen by enzymatic lysis.
