Answer:
Option-E
Explanation:
Meta arteriole is a type of vessel present in the micro-circulatory pathway of the human body, which possesses characteristics of both the arteriole and the capillaries.
The structure of metarteriole usually connects the arteriole to the venules and they possess smooth muscle rings at the entrance of the vessel in the capillary and thus acts as a sphincter. This sphincter controls the flow of blood into the venules and capillaries.
The precapillary sphincters are usually closed but when the tissue needs the oxygen the sphincter opens and supplies the blood.
Thus, Option-E is correct.

<span>RNA's nucleotides are made of a ribose sugar while DNA's are made from a deoxyribose sugar. The difference is that deoxyribose sugar has one less oxygen than a normal ribose sugar.RNA's nucleotides are composed of Uracil an alternate nitrogenous base to Thymine. So the sequence of nitrogenous bases is composed of Adenine, Uracil, Cytosine, and Guanine opposed to Adenine, Thymine, Cytosine, and Guanine.<span>RNA is mainly found in a single stranded form where it loops around itself. DNA on the other hand is a double stranded helix.

the shrimp), but also fungi and insects, and also has a structural function in
the scales of fish. The most similar commonly-known substance in terms of
function is keratin, which makes up our hair and nails.
