Answer:

The answer is B.

Explanation:

Acetoacetate and Acetyl CoA share a precursor with cholesterol synthesis which begins with Acetyl Coa but not β‑hydroxybutyrate.

Modifying other enzymes can be said for β‑hydroxybutyrate but not Acetoacetate.

They are not both produces from Acetyl Coa of fats. β‑hydroxybutyrate is produces from the acids with fats in the liver but the same can not be said for Acetoacetate.

However they both can be said to provide energy for the brain because they are both released into the bloodstream in the event of hunger or when the body/brain needs energy in a state of fasting.

I hope this answer helps.

After the completion of meiosis II, how many copies of gene A does each of the daughter cells contain?
balu736 [363]

Answer:

1

Explanation:

During meiosis, a diploid cell ultimately forms four haploid gametes that go on to take part in fertilization. Because they are haploid. that means they have one copy of all of the chromosomes and the genes contained within them.

First, the DNA is replicated, and then two cell divisions take place form the haploid gametes. So at first, there are two copies of each gene, creating four after the DNA is replicated.

After the first cell division (meiosis I) there are two cells with 2 copies of every gene. Then to form the haploid gamete, there is another cell division (meiosis II) creating 4 cells each containing one copy of every gene
