Answer:

B.their atoms are rearranged

Explanation:

All the chemical reactions follow the <u>rule of conservation of matter</u>. This rule states that matter can neither be created nor be destroyed during a chemical reaction. The number and type of atoms on the left hand side of a chemical reaction will be same on the right hand side of that chemical reaction. The atoms of chemical species/substances on the left hand side represent reactants while on the right hand side represent products. The only difference is that these atoms get rearranged when the products are formed.

Arturiano [62]

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>
