Mario requires a medication that will lower his blood pressure by relaxing the blood vessels and decreasing the blood volume. which class of medications would mario’s doctor prescribe?

Answers

The classification of dreugs that relax the blood vessels and decrease the blood volume are called: vasodilator medications. Examples of vasodilator medications are: nitroglycerin and minoxidil.

Answer: Vasodilator

Explanation:

If a person is suffering high blood pressure then the pressure inside the blood vessels increases because of vasoconstriction. Vasoconstriction is a condition in which the diameter of the blood vessels decreases and blood pressure increases.

In this case, vasodilators are given to the patients which helps in increasing the diameter of the blood vessels so that the pressure inside the blood vessels decreases.

What is the special function of the mucosa in the esophagus that explains why it is relatively thick and smooth while in most areas of the digestive tract the mucosa is relatively thin and folded?

Answers

Answer;

To protect the rest of the esophagus from sharp food particles and stomach acid.


Explanation;

The mucosa is the innermost layer, and functions in absorption and secretion. It is composed of epithelium cells and a thin connective tissue.

It contains specialized goblet cells that secrete sticky mucus throughout the GI tract, that prevents the corrosion of the stomach walls and esophagus from sharp food particles and the acids from the stomach.

Divergent volcanoes tend to have which of the following characteristics? A. Explosive, producing large amounts of thermal energy B. Explosive, producing large amounts of ash C. Nonexplosive, producing large amounts of lava D. Nonexplosive, moving along the sea floor with continental drif

Answers

A. Explosive, producing large amounts of thermal energy


Volcanoes form at different plate boundaries because of the plates divergent and convergent nature. the plates are always in motion, however minimal they may be. When the plates move apart from each other, the magma from below comes up to fill in the vacant space and thus a volcano is formed. It may be the other way round also and that is the magma forces the plates to move away and this results in the formation of a volcano. When one of plates dives under another plate, then the pressure creates melting of the mantle and thereby forms magma which in turn creates volcanoes.

Answer : Option C) Non explosive, producing large amounts of lava.

Explanation : The divergent volcanoes has the tendency of being non-explosive in nature. They help in producing large amounts of lava. The lava production is increased in these volcanoes.

Provide 3 points of interest about translation of the cell.

Answers

In Biology, the process of translation is where proteins are created from cellular ribosomes. The process of translation is composed of three phases: Initiation, Elongation, and Termination.

During the Initiation, ribosomes assemble around the target mRNA and tRNA is attached at the start codon. tRNA then transfers amino acid to the tRNA of the next codon during the Elongation. While the ribosome creates the amino acid chain while moving to the next mRNA codon. During the Termination, ribosome releases polypeptide in the stop codon.
