I believe in the presence of oxygen, an increase in the amount of ATP in a cell would be expected to inhibit the enzyme and therefore, slow the rates of glycolysis and the citric acid cycle. Phosphofructokinase is and enzyme that phosphorylates fructose 6 phosphate in glycolysis. It is an important control enzyme in the regulation of cellular respiration. It is inhibited by ATP and is an allosteric enzyme.
Answer:
Sister chromatids.
Explanation:
Sister chromatids are the two identical halves of a chromosome that are held together at centromere with help of cohesin. DNA replication in the S phase of the cell cycle doubles the amount of DNA. The copies of the DNA formed during DNA replication are accommodated in sister chromatids. Hence, two sister chromatids of a chromosome carry the identical DNA helices and associated proteins.
Answer:
The correct answer is "yes, yes, no" or "B, B, A".
Explanation:
In the hypothetical situation stated in the question, an inhibitor blocks the function of the motor proteins in the kinetochore, but allows the kinetochore to remain attached to the spindle. The animal cells treated with this inhibitor would be able to elongate during mitosis, their sister chromatids would separate from each other but the chromosomes would not move to the poles of the cell. The inhibitor only action is to block the function of the motor proteins, and since the motor protein function is to move the chromosomes to the poles of the cells, this will be the only activity that will be affected during cell's mitosis.

Answer:
A) cells of the tail dying and the nutrients being absorbed and reused by the body
Explanation:
The tails of the tadpole die when metamorphosing into an adult frog through a process Called Apoptosis. Apoptosis happens when it’s necessary for the body to kill some cells for development or other factors.
The cells which are killed produces nutrients which are then used and reabsorbed back into the body system of the frog.
