4 0

The main difference between parasites and predators is that the former are organisms that live at the expense of another organism, called the host, while the latter capture and feed on another organism, called the prey. Parasites are generally smaller than their host, whereas predators are typically larger than their prey. Moreover, parasites do not kill their host, but predators often kill their prey.

The relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.

<h3>What is sequence homo-logy?</h3>

In molecular biology, sequence homo-logy means the degree of similarity between sequences due to a common ancestor.

A sequence is a given fragment of a single DNA strand where nucleotides are arranged in a specific linear order.

Divergence or separation between lineages is directly proportional to the level of sequence homo-logy.

In conclusion, the relative time of divergence from a common ancestor can be estimated by comparing the nucleotide/protein sequence.

A group of scientists designed a clinical study to investigate the effects of cholesterol deficiency in humans. For the duration

viva [34]

Answer:

c. none of the subjects to show signs and symptoms of a cholesterol deficiency during the entire study.

Explanation:

this is because the blood cholesterol is from two sources. Nearly 80% of the cholesterol the body needs are made by the liver and intestine.certain small amounts are also produced in the adrenal glands and the reproductive organs.The remaining fragment amounts comes from the diets.

Therefore even if these subjects were fed with diet without cholesterol, it will not have any significant effects on the body cholesterol composition. Therefore no symptoms of its deficiency will be observed.

Generally it biosynthesis is regulated by the amount of cholesterol present in the blood.
