<h3><u>Answer;</u></h3>
When an area is holoendemic, the HbS allele frequency is between 0.52 and 4.04.
<h3><u>Explanation;</u></h3>
- <em><u>HbS allele is the sickle cell hemoglobin allele that provides immunity to malaria. This is because people with the sickle cell allele have a selective advantage in areas where there is a high incidence of malaria.</u></em>
- Therefore, natural selection will favor the population with HbS allele in a Malaria holoendemic (most individuals are infected) region. The HbS allele frequency in this population is expected to be high.
- After malaria is cured, the frequency of the HbS allele should decrease in regions with a lot of mosquitoes because having one copy of the HbS allele will no longer be advantageous in these regions.

Answer: A) Increased GI mobility
Explanation: They sympathetic nervous system inhibits the activity if the stomach, therefore, GI mobility decreases and does not increase. The parasympathetic nervous system is the one that increases the GI mobility.
Answer:
