Sickle cell anemia is caused by a recessive allele. A person must have a recessive allele from each parent to have the disease. A person who is heterozygous for sickle cell anemia does not have the disease. In
addition, this person is protected against malaria. Malaria is a disease that is common in countries in
Africa where people are more likely to have sickle cell anemia. A person who is heterozygous for sickle
cell anemia is somehow protected from malaria.
Assume that S represents the normal allele and that s represents the allele 2 points
for sickle cell anemia. What is the genotype for a person who is
heterozygous for sickle cell anemia?

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.

bradycardia ( blood presssure below 120/80mmhg )

it is contraindicated to give nitroglycerin to patients with blood pressure that is lower than normal range because the drug can cause blood pressure to drop further. it can lead to paradoxical bradycardia and less commonly, threatening hypotension.
