Where in the body would you find low oxygen levels causing vasoconstriction and high levels causing vasodilation?

The correct answer is the lungs. Usually, in the systemic organs such as the liver, kidneys, and the heart; hypoxia or low oxygen levels cause the blood vessels supplying them to vasodilate to increase flow of blood and prevent ischemia. Adequate oxygenation of systemic organs cause the blood supply to vasoconstrict to prevent pooling of oxygenated blood and shunt it to other organs that need the oxygen more.

However, in the lungs, the opposite is true because in the setting of hypoxia, the blood vessels of the lungs vasoconstrict as to shunt the blood to other parts of the lungs with adequate oxygenation for the blood to be adequately oxygenated. If there is adequate oxygen in the lungs, then blood vessels vasodilate to efficiently get the oxygen from the lungs.

<span>The answer for the question is the lungs.
Vasodilation means the smooth muscles in the blood vessel walls relax causing them to widen. The widening results in less vsacular resistance, thus the blood flow through the dilated vessel increases. Vasocontsriction on the other hand means the smooth muscles in the blood vessel walls contract causing them to narrow. The action results in blood flow through the vessels to be restricted. </span>

Put the following events in the correct order:
Wewaii [24]

Answer:

Explanation:

c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.

a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.

b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.

The process of deoxyribonucleic acod starts with replication to transcription and translation.

Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.

transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.

Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).

Hence the arrangement is from C ---- A-----B.

Cloned DNA can be store for use in vectors in a ________.
tankabanditka [31]
Plasmid. A plasmid is a small circular DNA presents in bacterial cells. It is used as a cloning vector for DNA. The cloned DNA and the plasmid are treated with a restrriction enzyme. The enzyme will make cleaveges in the same portions of the two DNA. The plasmid is then allowed to be replicated inside the bacterial cell.

Which of the following is not due to water’s surface tension?
jonny [76]

The correct answer is option D, that is, ice floating on the water surface.  

The cohesive forces among the molecules of a liquid are accountable for the process called surface tension. Surface tension refers to the tension of the surface film of a liquid resulting due to the attraction of the particles in the surface layer by the bulk of the liquid that seems to reduce the surface area.  

The examples of surface tension are walking of small insects on water, floating of a needle, the surface tension of water offers the essential wall tension for the creation of bubbles with water, and surface tension is accountable for the shape of liquid droplets.  

The low density of ice makes it float at the liquid water surface, like ice cubes in a glass of water, or an iceberg. The lower density of water in its solid form is because of the way hydrogen bonds are aligned as it freezes, the water molecules are pushed further far away in comparison to the liquid water.
