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:
all direction,
the cytoplasm of the cell has lower concentration than the surrounding solution
DNA and RNA (Deoxyribonucleic Acid Ribonucleic Acid)
Answer: Option C - Their paths would be identical to those of α-particles with lower energies.
Explanation:
Note that the PATHS TRAVELLED and deflection observed in the Rutherford gold foil experiment was based on ELECTRIC CHARGE carried by the individual particles NOT energy levels.
So, even after increasing the energy levels, their paths would be identical to those of α-particles with lower energies.
