Answer:
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.
<u>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</u>. The progressive increase in lymphocytes may be an indication of this.
The other options are not possible because:
- <em>Administering </em><u><em>antibiotics</em></u><em> should not raise lymphocyte levels.
</em>
- <em>There is no evidence of </em><u><em>antigen </em></u><em>attack.
</em>
- <u><em>Immunosuppressant drugs</em></u><em> do not increase lymphocyte count.</em>

Answer:
Human genetic code is the information present in genetic material that is changed into proteins by the combination of amino acids. With the help of this, we can check whether an organism is suffering from some disease or not . As it explains the order of amino acids to synthesize protein .

I believe it is actually commensalism as only one of the organisms is actually deriving a benefit, for example Remora fish live on sharks and whales in order to clean them by eating particles attached to them
