Answer: #4
Explanation: if they are different shapes and preform the same rate and job that wouldn't make sense and they cant work at different rates because they need to work together, therefor by process of elimination #4 is the answer
<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:
not 100% sure but
Explanation:
might be because each fruit fly has a different eye color because offspring from parents will have different eye color. or it might be from some sort of mutation that happened, that might be why they still have the gene to orange eyes. or red eyed fruit flys(or fly) migrated into a orange eyed populating and had offspring like that, that would also explain why red eyed fruit flys have the orange eyed gene.
again not 100% sure
but I hoped it helped a little
