Explanation:
The inbreeding process, are blood crossings between relatives who have a common ancestor. Inbreeding leads to an increase in the frequency of homozygous genotypes and a decrease in the frequency of heterozygotes. We may also note that although changes in genotypic frequencies occur, no changes in allelic frequencies are observed over successive generations of self-fertilization. The main consequence of 2 individuals sharing one or more common ancestors is that they may carry replicas (identical copies) of one or more genes present in these ancestors. And if these individuals mate, they can pass on such replicas to their offspring, generating self-sibling offspring, that is, with two identical copies of the same gene that was present in these common ancestors.
Answer: 3(three)
Explanation:
In the biosynthesis of phosphatidylethanolamine from ethanolamine and triglyceride, 3 high energy molecules are used in the first and second step.
The first steps occur in the cytosol, where ethanolamine is phosphorlated with ATP to give phosphoethanolamine and ADP by the enzyme ethanolamine kinases, and in the next reaction which is the rate-limiting step, phosphoethanolamine react with cytidine triphosphate (CTP) to form cytidine diphosphoethanolamine. In this reaction two molecules of phosphate group is given off.
The third step occurs in the endoplasmic reticulum CDP-ethanolamine react with diacylglycerol to form phosphatidylethanolamine.
The answer is Three high energy molecules. One molecule of ATP to form phosphorylethanolamine and two molecules of ATP to regenerate CTP from CMP.

The correct answer is C. Estivation
Explanation:
In biology, estivation refers to a lethargic state that is mainly prompted by high temperatures, different from hibernation that occurs in the winter or at low temperatures. However, as hibernation estivation implies the organism of animals lowers the metabolic rate with the purpose of avoiding to die due to the high temperatures and the lack of resources including water. This can occur in both vertebrate and intervertebral animals including small animals. This implies, the mouse described which is a small animal probably is going through estivation as due to hot temperatures the organism lowers the metabolic rate, which is exactly what occurs in this process.
