Both the Amy and Rosalie are correct.

What is Circulatory system?</h3>
The heart, blood vessels, and blood itself circulate throughout the entire body of a human or other vertebrate through the blood circulatory system.
The blood contains of the red and white blood cells along with plasma and other substitutes of blood.
Also the blood has the function to supply the nutrients to the cells of the body along with transporting carbon dioxide to the alveoli of the lungs.
The circulatory system is a closed pack system with the involvement of various organs like the heart the lungs and plays a crucial role in maintaining the homeostasis of the body.

Answer:
The fact that the amino acid chain is consistently having more amino acids than what is actually present can be attested to the fact of how gene expressions can be observed in the prokaryotic cell compared to the eukaryotic one.
Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.
Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.
In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.
Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.

Answer:
Produce Energy
Explanation:
Pyruvate, a product from glycolysis, is converted into acetyl CoA in the mitochondria .
The 3-carbon pyruvate molecule loses a carbon to produce a new, 2-carbon molecule called acetyl CoA. The carbon that is removed takes two oxygens from pyruvate with it, and exits the body as carbon dioxide. The pyruvate dehydrogenase complex catalyzes this reaction
The conversion of pyruvate to acetyl-CoA produces NADH.
The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors.
Answer:
OJ. They stimulate maximum root and stem growth at different concentrations.
Explanation:
Looking at the graph found in the attachment below, conclusions can be drawn about the effect ofnthe difference in concentration of plant hormones in the two different parts of the plants under consideration, the roots and the stem.p
Considering the roots;
maximum growth of the roots of plants as seen by the upward curve ofbthe arrow, is obtained when plant hormones are at low concentrations. However, with increase in the concentration of plant hormones, the growth of root diminishes as seen bynthe downward slope of the curve.
Considering the stems:
At low concentration of hoeprmones, the growth of stem is very minimal. However, with increase in concentration of plants hormones, a rapid upward shoot is seen in curve indicating a rapid increase in growth. Maximum growth occurs at high concentration of plant hormones.
Therefore, the proper conclusion is that, plant hormones stimulate maximum root and stem growth at different concentrations.
