Mutation is made once in every thousand nucleotides copied.

Mutation creates different versions which have the same genes which are known as alleles.
They create variation in protein-coding. We put sunscreen to protect us from a mutation in somatic cells.

Answer: The correct answer for the fill in the blank is 10 billion nucleotides.

Mutation can be defined as the permanent change in the nucleotide sequence of the genome. It can be caused due to error in the DNA replication or a DNA damage, which can be caused by several reasons like exposure to radiations.

A mutation is made once in every 10 billion nucleotides copied.

This is because the overall error rate of the enzyme DNA polymerase is 10⁻¹⁰ per base pairs. This means that there is a chance of one mutation in every 10 billion nucleotides that are replicated.

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.
