Answer:
the secondary response of the adaptive immunity is faster and more efficient than the primary response
Explanation:
A vaccine works because antigens, molecules that are specific to certain pathogens, are introduced to the body producing antibodies when the immune system recognizes them as external bodies, <em>this generates memory in the immune cells so the second time the body encounters this pathogen again, it will recognize the antigens and generate a faster immune response</em>.

Explanation:
<span>Pangaea was the last of the great continents. Wegener hypothesized that all of the continents were one continent based on physical evidence that he collected. The shapes of the shores, matching mountain ranges and fossils/plants found on different continents. What Wegener did not have was the mechanism. Hess in 1963 discovered what is now called Mid-Ocean ridges. What accurs here is faults in the crust allow magma to move to the surface. The build up of magma, rift valeys leads to divergence of the plates moving apart. The continents began to pull apart and move away from each other. But as contnients move away from each other essentially they are also moving towards each other from another reference point. Now new have oceanic crust/plates moving towards continental plates leading to convergence. Look up the Wilson Cycle. It is like talking about what comes first, the chicken or the egg and if you do not look at the very beginning of earth it does not fully make sense.</span>
Answer:
Incest
Explanation:
This is illegal because it is bad for genetics
Answer: Option a) the frequency of the homozygous dominants will go down, the frequency of the heterozygous genotype will go down, and the frequency of the homozygous recessives will go up
Explanation: Another name for gene frequency is the allele frequency. It is the percentage of any chromosomes in the population that contains that particular gene or allele. It also shows the genetic diversity that can present in a species.
