Answer:

Sympathetic Nervous System.

Explanation:

Sympathetic nervous system is one of the parts of Autonomic nervous system and the other part is Parasympathetic nervous system.

As a whole the autonomic nervous system controls the unconscious responses of our body.

The main function of the Sympathetic nervous system is to stimulate the 3F response of the body. Here 3F refers to Fight, Flight and Freeze. Adrenal gland is stimulated by this system which secretes adrenaline. Due to the effect of adrenaline heart neat increases, blood pressure increases, pupils dilate, sweat glands are activated, peristalsis in the gut is inhibited, and kidney secretion increases.

Answer:

Option A, shared their data with colleagues to obtain feedback on the work.

Explanation:

All researchers prefer to share their findings with their peers or other researchers working in the same field to get their reviews. This step is very essential as it makes the research authentic and removes the flaws that would have otherwise missed by the researcher.  

Peer reviewers also give useful suggestion to further modify one’s research study based on their experiences.  

Hence, option A is correct

<h2>A) option is correct </h2>

Explanation:

  • RNA is a linear polymer of ribonucleotides
  • Sugar in RNA is ribose instead of deoxyribose which is present in DNA
  • The four nitrogenous bases present in RNA are adenine, cytosine, guanine and uracil whereas that in DNA are adenine, cytosine, guanine and thymine
  • RNA molecules carry genetic information from DNA to proteins, cannot transmit from one generation to next generation as a genetic material
  • Due to steric hindrance by the 2'-OH group of ribose sugar, RNA unable to form double helix

Umnica [9.8K]

Answer:

Genetic mapping for unequivocal identification of the potentially causative mutation  

Explanation:

Galactosemia is a genetic disorder caused by mutations in the Galactose-1-phosphate uridylyltransferase (GALT) gene, which encodes an enzyme involved in the metabolism of galactose. Gene mapping is a technique widely used in genetics to identify the position of one locus a chromosome by using molecular markers to estimate genetic distances. Genetic mapping provides useful evidence in order to identify when a disease that is transmitted from parent to offspring can be associated with one or more genes and then determine which gene/s is/are responsible for this condition.
