Answer:

1) Macrophages ingest antigen 2) Helper T cells are activated 3) B cells differentiate into plasma cells and memory cells.

Explanation:

Innate immunity and adaptive immunity provide protection against foreign invaders. Innate immunity is non specific and adaptive immunity is specific immune response; includes the production of antibody after a sequence of events.

  • When an antigen enters the body the phagocytic cells such as macrophages and dendritic cells ingest the antigen by a process called as phagocytosis. These cells act as antigen presenting cells and present it to T cells.
  • T cells are of two types T helper cells and T cytotoxic cell. T cytotoxic cells killed the affected cell such as affected by virus while T helper cells signal for the production antibodies.
  • Antibodies are produced from the plasma cells while memory cells act as record keeping. The plasma cells are stimulated by interleukins.

"if left untreated, hypertension can lead to ____."
katrin2010 [14]

If left untreated, the probable lead for hypertension to an individual is kidney failure. It is because the blood pressure is associated with the kidneys because the nephrons of the kidneys are being supplied with the blood vessels dense network and also because of the blood that flows through it, when there is a presence of hypertension and left untreated, it could cause the kidney to weaken or harden—causing kidney failure.

What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?
Zinaida [17]

Answer:

Base substitution mutation

Explanation:

Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:

ATCGGCTTAACG to ATCGGCTAAACG

This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.

Explain how seasonal changes in carrying capacity can account for the annual cycles in population size observed for this populat
murzikaleks [220]
<span>Carrying capacity is how many animals a given location can hold. This means that if the number of rabbits, n, exceeds the carrying capacity, C, then the difference between the number of rabbits minus the carrying capacity (n - C) will likely die to starvation. Seasons in Ohio can directly affect carrying capacity because colder weather usually means less food. Rabbits can eat plants as well, and in winter, plants do not do well to survive. Thus, the carrying capacity will decrease. In contrast, in summer, plants flourish so the carrying capacity will increase.</span>
