Give the sequence of mRNA that would match the following DNA strand
sladkih [1.3K]

Answer:

Below

Explanation:

mRNA is a complimentary copy of a DNA segment (gene) and consequently can be used to deduce the gene sequence. For converting a sequence from mRNA to the original DNA code, apply the rules of complementary base pairing: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A).

The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain. The anticodon is the complementary three nucleotide sequence in the appropriate tRNA.

Angiotensin II and ADH (in high doses) ____________ peripheral resistance and blood pressure; and angiotensin II, aldosterone, a
Nuetrik [128]

Answer:

Angiotensin II and ADH (in high doses) ___Increases_________ peripheral resistance and blood pressure; and angiotensin II, aldosterone, and ADH ___Decreases_________ urine output to help maintain blood volume and blood pressure. ANP stimulates__volume receptors_____ , which decreases _peripheral resistance__________ and increases _in porasium serum_______ , which decreases blood ____volume________ . The net effect is a decrease in blood ____Pressure________

Explanation:

Angiotensin II is a powerful vasoconstrictor, greatly increasing blood pressure. It also stimulates the release of ADH and aldosterone, a hormone produced by the adrenal cortex. Aldosterone increases the reabsorption of sodium into the blood by the kidneys.

Atrial natriuretic peptide (ANP) is released in response to increased stretch in atria as a consequence of high blood volume and high blood pressure. The effect of ANP is to decrease both peripheral resistance and blood volume with a resultant decrease in blood pressure to within normal homeostatic limits.

The surface area to volume ratio defines what aspect of a cell
ratelena [41]
Answer - It defines how much a cell can do metabolic exchange and chemical substance exchange.

Reasoning - A Cell that is large has the ability of inadequate to provide the cell its nutrients and metabolic needs for the exchange in chemical substances.

Whereas  a small cell does not take up space and can exchange quicker with chemical substance and nutrients because of its size to the surface area.
