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:
Cb>Cy>Co>Cr
Explanation:
First of al we need to do the Punnett square. As a result we get the genotypes:
CyCb
CyCr
CoCb
CoCr
Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.
Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.
The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.
As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.
