Mutations acquired by somatic cells are generally only retained by the individual they acquire in as there is no vector by which to transmit the mutation.
<span>Between generations, the only mutations that may be transmitted are those already acquired from a parent, and those that occur within the individuals own germ cells. If mutations in the germ cells result in sperm or eggs that contain that mutation, then they may be transmitted to their offspring. </span>
<span>Red blood cells in all humans and other mammals, though, don't contain nuclear DNA and as such cannot acquire mutations.</span>
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.
