B

Gene flow is the transfer of genes/alleles from one population to another.

Explanation:

Gene flow adds to genetic diversity of the population into which the gene transfer occurred. In this case the pollen carries different forms of genes and alleles from the population it came from and when it cross-fertilizes with the new population, it adds to the genetic pool of the new population.

Another example of gene flow is through migration - the individuals of  from one population join another population and continue to mate randomly in the new population. The immigrants come with new alleles of genes that become amalgamated into the new population by cross-breeding.

The correct answers are:

Trematodes are acoelomates that have effective defenses against attack by their hosts' immune system.

Trematodes are flatworms, internal parasites known as flukes. Their life cycle is complex: they sexually reproduce in vertebrates and asexual reproduce in mollusks (mostly snail). The body of flukes is covered with tough tegument that defends them form digestive enzymes of host’s intestine.

Cnidarians are diploblasts that produce complex, capsule-like organelles.

Cnidaria are water organisms with simple structure: two layers of epithelium and a jelly substance between them. The cells of Cnidaria-cnidocytes contain capsule with venom substance in it with protective role.
