The ligand that activates the g-protein linked receptor is:
Answer:
When a ligand binds to the GPCR it causes a conformational change in the GPCR, which allows it to act as a guanine nucleotide exchange factor (GEF). The GPCR can then activate an associated G protein by exchanging the GDP bound to the G protein for a GTP.
Which of the following statements about the law of independent assortment is correct?
A. It is the reason that dominant alleles are visible in the organism's phenotype.
B. It is the consequence of having two copies of each chromosome in somatic cells and one copy in gametes.
C. It describes the inheritance of different genes relative to one another.
D. It describes the inheritance of different alleles relative to one another.
The statement about the law of independent assortment which is correct is: C. It describes the inheritance of different genes relative to one another.
Independent assortment can be defined as a biological process through which the inheritance pattern of a particular gene doesn't affect the inheritance pattern of another gene.
This ultimately implies that, the inheritance pattern of different genes with respect to another gene is given by the law of independent assortment.
In conclusion, the law of independent assortment describes how different genes separate with respect to another gene during the development of reproductive cells.

which antioxidant plays an important role in cell differentiation, the process by which stem cells mature into highly specialized cells?
Vitamin A is regarded as the antioxidant that plays an important role in cell
differentiation.
Cell differentiation is the process by which cells become specialized by
changing from one form to another to achieve a common structure and
function.
Vitamin A has a strong metabolite known as retinoic acid which is involved
in this process which supports it and also helps to eliminate the free radicals
which may be present.

What are the blood vessels that carry blood to and from the lungs?
Answer · 5 votes
To expand on Dr. Herman’s answer. The pulmonary artery, originating in the right ventricle, carries deoxygenated blood from the heart to the lungs (most other arteries, though, carry oxygenated blood), to be oxygenated in the lungs. The pulmonary veins, terminating in the left atrium, carries oxygenated blood (most other veins, though, carry deoxygenated blood) from the lungs to the heart, to be distributed to the rest of the body.

Which blood vessels carry blood away from the heart?
Answer · 0 votes
Arteries & Veins. Explanation: The ARTERIES are major blood vessels connected to your heart. 1. The pulmonary artery carries blood from the right side of the heart to the lungs to pick up a fresh supply of oxygen. 2. The aorta is the main artery that carries oxygen-rich blood from the left side of the heart to the body. 3. The coronary arteries are the other important arteries attached to the heart. They carry oxygen-rich blood from the aorta to the heart muscle, which must have its own blood supply to function. The VEINS also are major blood vessels connected to your heart. 1. The pulmonary veins carry oxygen-rich blood from the lungs to the left side of the heart so it can be pumped to the body. 2. The superior and inferior vena cavae are large veins that carry oxygen-poor blood from the body back to the heart.

B. Pulmonary ArteryAs a general rule, all Arteries in an adult human carry oxygenated blood. (Away from heart)Veins (think venir "to come" in Spanish) will carry deoxygenated blood back to the heart. The exception to this is the pulmonary vessels as the pulmonary veins bring back freshly oxygenated blood exchanged at the lungs. Hope it helps!

Answer · 3 votes
A blood vessel carrying blood from the lungs to the heart is pulmonary vein. There are four pulmonary veins, two from each lung that drains into the left atrium of the heart. Pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart. This differentiates the pulmonary veins from other veins in the body, which are used to carry deoxygenated blood from the rest of the body back to the heart.So, the correct answer is 'Pulmonary vein'.
