a. all of his daughters.
b. half of his daughters.
c. all of his sons.
d. all of his children.
Only his daughters would inherit an X-linked allele from a male who bears it. This implies that he would also exhibit the attribute that this allele influences.
Men only have one X chromosome, thus if an X-linked condition is found on the male X chromosome, it will almost always manifest. Through mutations (changes) in a gene on the X chromosome, a genetic characteristic or condition can be handed on from parent to kid in a process known as X-linked recessive inheritance.
A mutation in the gene copy on the one X chromosome in males (who only have one X chromosome) causes the disorder. The disorder can only affect females (who have two X chromosomes) if there is a mutation on both X chromosomes.

Summarize the stages of cellular respiration and explain its relationship to body temperature.
Cellular respiration happens in one of two ways depending on whether oxygen is present or not.
Both of them start with glycolysis, which takes place in the cytosol and doesn't require oxygen. Glycolysis: Two pyruvate molecules are produced when two glucose molecules are broken in half.
The next stage is when the pyruvate reaches the mitochondria, where it is bound to Acetyl CoA and undergoes pyruvate oxidation. Carbon dioxide is a waste product that enters the circulation fast before being released by the lungs. It also produces NADH.
Acetyl CoA bonds to a four-carbon molecule and begins the citric acid cycle, often known as the Krebs cycle. The cycle's initial four-carbon molecules, NADH, FADH2, ATP, and carbon dioxide are its end products. Here, carbon dioxide also constitutes a waste product.
Oxidative phosphorylation: NADH and FADH2 revert to NAD+ and FAD by donating their electrons to the electron transport chain (commonly abbreviated as ETC). Energy is produced by oxygen pulling electrons through the ETC.
Up to a point, temperature accelerates cellular respiration. On a graph, the relationship between temperature and cellular respiration appears as something resembling a bell curve. Cellular respiration speeds up when the temperature rises.
