The drug Viagra promotes blood vessel dilation by prolonging signaling through nitric oxide (NO). How does Viagra boost NO?
a. It inhibits guanylyl cyclase in smooth muscle cells.
b. It prevents acetylcholine from binding to its receptors.
c. It stimulates guanylyl cyclase in smooth muscle cells.
d. It blocks the enzyme that degrades cyclic GMP.
e. It binds to acetylcholine receptors on endothelial cells.

Answers

Answer:

The correct answer is option d, that is, it prevents the enzyme, which degrades cyclic GMP.

Explanation:

Oral therapy for erectile dysfunction is Viagra, which is the citrate salt of sildenafil, it works by preventing a specific phosphodiesterase type 5 or PDE5, which is the inhibitor of cGMP. During sexual stimulation, nitrous oxide is released in the corpus cavernosum causing the erection of the penis in males. The nitrous oxide then stimulates the enzyme guanylate cyclase that further makes the concentration of cGMP to elevate, this generates smooth muscle relaxation in the corpus cavernosum and permitting blood the inward flow of blood.

Viagra works by increasing the influence of nitric acid by preventing PDE5, which is accountable for the deprivation of cGMP in the corpus cavernosum. At the time of sexual stimulation, the discharging of nitrous oxide takes place, the viagra inhibits PDE5 causing the levels of cGMP to elevate in the corpus cavernosum leading to smooth muscle relaxation and continuous flow of blood to the corpus cavernosum.

In science fiction stories, plants that live on planets far from the sun are often described as having black foliage, while those that live on planets close to the sun are described as having shiny reflective foliage. If the plants on these planets do photosynthesis similar to terrestrial plants, discuss why these colors would be good adaptive features.

Answers

Answer:

See the answer below

Explanation:

The black foliage of the plants that live on planets far from the sun is an adaptive feature to maximize the heat from the sun for their metabolic activities. A certain level of temperature is usually required for optimal metabolic activities and the distance away from the sun means that heat could be a limiting factor. A black color, however, is able to absorb all the available heat in the surrounding. Hence, the black leaf color serves to maximize the heat from the sun for the benefits of the plant.

The shiny reflective foliage of the plants that live on the planets close to the sun can also be viewed as an adaptive feature to minimize the effects of the proximity of the sun. Too much sunlight will cause the tissues of the leaf to heat up beyond the optimal temperature requirement for metabolic activities. A shiny reflective color will reflect more of the rays of light from the sun than it absorbs. Thus, the foliage is prevented from overheating.

Porotic hyperostosis and an iron deficiency anemia

Explanation:

Iron deficiency anemia is a popular type of anemia caused by the deficiency of the mineral iron in the blood. The body needs iron to produce hemoglobin which helps to distribute oxygen in the body. When there is no iron in the blood, the entire body would be deprived of oxygen.

Porotic hyperostosis is a condition whereby the bones in the skull or cranial vault becomes spongy and swells. The cause of the condition could be the hemolytic or megaloblastic anemia that occurs as a result of excessive production of hemoglobin.

How might a mutation in the DNA of the Piedmontese bull lead to muscle hypertrophy

Explanation:

Answer:

A cell can be defined as the smallest unit of life and an example include muscle cells. An aggregation of cells form tissues.

The major difference between a cell structure and cell function is in their functions and physical properties.

Cell structure: This talks about how the cells look like when viewed. A call contains components such as the nucleus, cytoplasm, cell membrane etc and each has their various functions to ensure the organisms/animals are able to perform various life activities.

Cell function: This on the other hand refers to the various functions which a cell is able to perform and this is dependent on the component in question such as the nucleus which controls cell activities and cytoplasm which provides support and helps to house other organelles.

Explanation:

A joint can be defined as the location where two or more bones make contact.

Also, a ligament refers to a short elastic band-like tough fibrous tissue that holds the bones of a joint together so as to keep them in place. This joints are able to move (lengthen and shorten) as a result of the presence of muscles.

Basically, this junction known as joints are typically found in vertebrates and it allows for movement and structural support.

Hence, the ability of the human body to make movements such as sitting down, kneeling, standing up, bending, walking, running etc., is solely dependent on the joints. Thus, without joints all vertebrates would be completely rigid and static.
