Answer:

B) 4 ATP

Explanation:

The most favoured substrate of the cellular respiration is called glucose which on complete oxidation yields ATP.

The substrate level of phosphorylation is the formation of the ATP molecules from a phosphorylated intermediate and the ADP.

During glycolysis, the substrate-level phosphorylation produces 4 ATP molecules out of which 2 molecules are utilized during the process itself thus there is a net gain of glycolysis produces 2 ATP molecules.

Thus,  4 ATP is the correct answer.

balu736 [363]

Answer:

indeterminate

Explanation:

The answer would be <u>an indeterminate number of generations.</u>

The blue trait is a heterozygous trait. In other words, the blue allele does not really exist. Two different alleles team up to produce the trait, whereas, only two the same allelic conditions can produce a true-breeding flock.

<em>Hence, it will take an indeterminate number of generations to produce a true-breeding flock of the Blue Andalusions.</em>

kondor19780726 [428]

The coronary arteries supply blood to cardiac tissue. The left ventricle chamber of the heart requires the greatest amount of blood supply to keep it working.

Coronary arteries

The heart muscle receives blood from the coronary arteries. The heart muscle needs oxygen-rich blood in order to operate, just like all other bodily components do. Blood that lacks oxygen must also be transported away. Outside of the heart, the coronary arteries encircle the organ.

The coronary artery that is blocked the most frequently is the LAD artery. The interventricular septum, and therefore bundle branches of the conducting system, receive their primary blood supply from it.
