Why are small populations more prone to genetic disease

Answers

Answer:

Inbreeding and greater chance of passing deletereous mutations through generations

Explanation:

There are several reasons why small populations are more prone to genetic diseases. One of them is that in small populations there tends to be more inbreeding , that is breeding between individuals are closely related. Inbreeding increase the chances of offspring being affected by deletereus homozygous genotypes.

On the other hand, the acquisition of a deleterious mutation in a small population is more likely to be spread in that small population than in a large population.

The small population is prone to the disease more than the large population as the former have less diversity of organism and therefore there are fewer chances of occurrence of an organism that have resistance to the disease.

Further Explanation:

Genetic drift refers to the change in the allele frequency observed in the population due to random sampling. This may occur due to a bottleneck effect or Founder’s effect.

The allele frequency remains constant if the population follows the Hardy-Weinberg equilibrium.

There is more probability of occurrence of diversity in a population of large size that is the large population has an organism that has homozygous dominant allele, heterozygous allele, and homozygous recessive allele. So there is more probability that this population may have an organism having disease-resistant allele than the population of small size.

Describe how feedback inhibition works

Answers

Say you have a pathway
A-->B-->C-->D

So your A leads to production of B which leads to production of C which leads to production of D
In feedback inhibition (or a negative feedback loop), the final product of a pathway (in this case, D) will usually inhibit or stop the first step in that pathway. So in this instance, D would do something to stop A-->B from occurring. It could bind A or the enzyme that makes that step occur.
Basically, the end product somehow stops one of the earliest steps in the pathway

What is the main function of digestion?

Answers

Your "Digestive System" breaks down food into molecules that are then absorbed into your body.

The main function of the digestive system is to convert food to energy and eliminate waste. The human digestive system is made up of several parts like the mouth, esophagus, stomach, small and large intestines, pancreas, liver, gallbladder, rectum and anus.

Biomolecules can be classified as lipids on the basis of

Answers

The question is incomplete as it does not have the options which are:

A) the presence of many hydroxyl groups and at least one carbonyl group.

B) the presence of at least one amine group and one carboxylic acid group on each molecule.

C) the physical properties of odor, color, and melting point within certain guidelines.

D) a common structure consisting of long hydrocarbon chains.

E) the physical property of solubility in nonpolar organic solvents.

Answer:

E) the physical property of solubility in nonpolar organic solvents.

Explanation:

Lipids are one of the biomolecules which are involved in the formation of various other complex molecules in the body. The structure of lipids contains a very long hydrocarbon chain which provides hydrophobic to the compound.

Since they are hydrophobic therefore cannot form bonds with the water and thus repel water. This molecule is therefore considered a non-polar molecule. These non-polar molecules are soluble in the non-polar organic solvents only.

Thus, Option-E is the correct answer.
