Answer:
percentage of the group heterozygous for the sickle hemoglobin allele = 32%
Explanation:
If
p = frequency of dominant allele
q = frequency of recessive allele
According to Hardy-Weinberg equilibrium: p² + 2pq + q² = 1 and p + q =1
where p² = frequency of homozygous dominant population
q² = frequency of homozygous recessive population
2pq = frequency of heterozygous population
Here, frequency of sickle cell disease (homozygous recessive) = 0.04
q² = 0.04
q = 0.2
p + q =1
So p = 1 - 0.2 = 0.8
Frequency of heterozygous population = 2pq
2 * 0.8 * 0.2 = 0.32
Hence percentage of people heterozygous for sickle hemoglobin allele = 32%
Answer:
Overcooked food (is not a common cause of foodborne illness.)
Explanation:
The correct answer is C. An insufficient amount of circulating cortisol
Explanation:
The main cause of adrenocortical insufficiency is the lack of production and circulation of hormones, especially of cortisol (steroid hormone). Moreover, the lack of cortisol is caused by damages in the adrenal glands. Besides this, this insufficiency leads to conditions such as Addison disease, which is associated with symptoms such as nausea, fatigue, dizziness, and can be life-threatening. According to this, the correct answer is option C considering insufficiency cortisol plays a major role in this condition.
