Opsins are proteins that are found in the light-sensing cells in the human eye. Different opsin proteins are sensitive to differ
Zepler [3.9K]

Answer:

Women who carry one copy of the mutated gene still have normal color vision because they have another copy, which is not mutated, in the other X chromosome that will be the dominant one. As a result, the women are carriers of the mutated gene but not color blind.

Explanation:

Colorblindness is a sex-linked mutation. A woman has two X chromosomes, while a man has one X chromosome and one Y chromosome. The mutated gene that causes color blindness is on the X chromosome, and it is OPN1LW. So if a woman has one mutated OPN1LW in one of her two X chromosomes, the OPN1LW gene in the other X chromosome will be the dominant one stopping the woman from being colorblind.

In the case of men, as they only have one X chromosome, if there is a mutation on the OPN1LW in the X chromosome, the men will be colorblind because there is no extra copy of the gene, as it is in women.

"In genetic modifications, DNA inserted can come from _____ ." any organism containing the DNA of interest only the same plasmid
liq [111]

Answer:

<h2> any organism containing the DNA of interest</h2>

Explanation:

  • Such type of process in which the modification of the genes of the organisms takes place is known as genetic modification and also called genetic manipulation or genetic engineering.
  • In such type of the process, the branch of biological science that is known as biotechnology is used.
  • In this mechanism, genes of interest are separated from the certain organism and then this gene of interest is inserted into the host organism and such type of DNA that is formed after the addition of foreign genes or DNA is called recombinant DNA.
  • Such type of DNA is used in the production of genetically modified organisms and some other fields for the benefit of human beings.

Compare parasympathetic nervous system vs sympathetic
Galina-37 [17]

Answer:

Parasympathetic nervous system effects are slow or inhibit function, where is sympathetic, is responsible for the intense physical activity.

Explanation:

The autonomic nervous system or ANS is divided into 2 distinct systems on the basis of their effects- the parasympathetic nervous system and the sympathetic nervous system.

Both of these have opposite actions on the functions that they maintain.

The sympathetic nervous system regulates the body for a high level of physical activity and also known as fight or flight. It fasts the functions of the body according to the situation.

The parasympathetic nervous system is having the opposite effect of the sympathetic nervous system slows high energy functions and relaxes the body.  

Thus, the comparison of these nervous systems is mention above.

Angiotensin-converting enzyme (ACE) inhibitors and other vasodilators are used in the early treatment of heart failure. They act
Iteru [2.4K]

Answer:

Option c. cause pooling of the blood and decreased venous return to the heart

Explanation:

The ACE inhibitors increases the diameter of the blood vessels (vasodilation) that improves the flow of blood. This reduces the work load on the heart. At the time of heart failure, a substance called angiotensin is released. This angiotensin formation is blocked by the ACE inhibitors. Angiotensin is involved in narrowing the blood vessels.

The ACE cause pooling of the blood and decreased venous return to the heart. The ACE inhibitors causes vasodilation that allows decrease in blood pressure. So, there is no increase in arterial pressure, aldosterone and loss of volume. Thus, option C is correct.
