best explanation as to why her lymphocyte levels were increasing?
O Kaya was given antibiotics to prevent infections.
Kaya's antigens were attacking the tissue.
Kaya was not tissue typed prior to her surgery, and her body is mounting an immune response.
O Kaya took her immunosuppressant drugs weekly, which increased her lymphocyte count.

The best explanation for the increased lymphocyte levels in Kaya is that she was not tissue typed prior to her surgery, and her body is mounting an immune response.

Explanation:

When performing an organ transplant, it must be verified whether the organ to be transplanted is compatible -by tissue typing- with the recipient, since it is recognized as a foreign body by the body and can be rejected.

One of the immunological responses to organ rejection is called cell rejection, involving T-helper and cytotoxic lymphocytes.

It is very likely that in Kaya's case the tests have not been performed correctly, and she is experiencing rejection of the organ she received. The progressive increase in lymphocytes may be an indication of this.

The other options are not possible because:

b. regulated is the actual answer to your question.

explanation:

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.
