A geneticist isolates a gene for a specific trait under study She also isolates the corresponding mRNA Upon comparison, the mRNA

olga nikolaevna [1]

Answer:

C) no, the final mRNA contains only exons, the introns were removed

Explanation:

Exons are the coding areas while the introns are non-coding areas. Both of these are the sequences of nucleotide within a gene.

RNA splicing is a process which usually occurs as the RNA matures, causing the removal of introns ( non coding areas of the RNA ) i-e they will not be expressed in the final messenger RNA, while exons continue to form covalent bonds with one another to form a mature mRNA.

So in the given scenario, Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence because the introns were removed by RNA splicing.

Hence option C) no, the final mRNA contains only exons, the introns were removed is correct.

Hemophilia is a condition in which blood does not clot naturally, and a person with hemophilia could bleed to death if injured.

barxatty [35]

As we know our blood has four main components which are plasma, red blood cells, white blood cells and platelets. That is why a hemophiliac must receive regular injections of platelets to stay alive. This is done by injecting into their bloodstream human plasma which contains many proteins, glucose, clotting factors, electrolytes, hormones, and carbon dioxide.

I hope it helps, Regards.

When the vasomotor center of our brain wishes to increase blood pressure, it increases ____________ signals causing ______.

dlinn [17]

When the vasomotor center of our brain wishes to increase blood pressure, it increases the heart rate signals causing The greater contraction of the heart causes more blood vessels to constrict, increasing the blood vessels' resistance.

By speeding the heartbeat, making the heart beat harder, and constricting some blood vessels, the sympathetic nervous system increases blood pressure. This will enhance the vessels' resistance.

What controls blood pressure by the vasomotor center?

The vasomotor center modifies the tone of the vascular smooth muscle. Both the local and systemic blood pressure are impacted by this. The vasomotor center produces increased sympathetic tone when blood pressure lowers. This causes an increase in blood pressure.

How is blood pressure regulated?

The autonomic nervous system has short-term control over blood pressure (ANS). Baroreceptors are capable of detecting changes in blood pressure. These are situated in the carotid sinus and aortic arch. High arterial pressure causes the blood vessel wall to stretch, activating the baroreceptors.

What systems regulate peripheral resistance in the vasomotor center?

The vasomotor center in the tunica media regulates smooth muscle contraction or vessel tone. Circulating output is impacted by changes in peripheral resistance, pressure, and flow. The majority of these neurons are in charge of causing sympathetic neurons to release the neurotransmitter norepinephrine.

mina [271]

Answer:

Determine the proportion of offspring phenotypes that would result when two merle dogs mate, if one dog is true-breeding for the long-coat trait and the other dog is true-breeding for the short-coat trait.
