Answer:
1/16
Explanation:
Sickle-cell disease is caused by a homozygous recessive genotype <em>dd</em>.
A man and a woman both heterozygous Dd will have the following offspring:
The probability of having a <em>dd</em> child with Sickle-cell disease is 1/4. Each time they have children the gamete combination is random, so the genotype of the second child is independent from the genotype of the first child.
According to rules of probability, if two events are independent from each other, the probability of both happening is calculated by multiplying the individual probabilities of each.
Therefore the probability of having the first two children with the disease is 1/4 x 1/4 = 1/16.

Explanation:
Answer:
The correct answer is glycolysis.
Explanation:
Glycolysis must happen before acetyl CoA can be formed during respiration.During glycolysis the precursor molecule glucose is converted to pyruvate by a series of enzyme catalyzed biochemical reactions.
Pyruvate in aerobic condition is then converted into acetyl CoA by the help of pyruvate dehydrogenase enzyme
