The right answer is 5.
To answer this question it is sufficient to take the same approach as the one that concluded that each amino acid is equivalent to 3 codons.
We have 17 amino acids, each of which must have at least one unique code (having two nucleotides A and T)
.
it is enough to apply this time to count the number of possible codons to be generated according to the number of nucleotides:
nucleotide set ^ number of nucleotides = number of codons
.
2 ^ 1 = 2 (<17)
2 ^ 2 = 4 (<17)
2 ^ 3 = 8 (<17)
2 ^ 4 = 16 (<17)
2 ^ 5 = 32 (> 17)
So, each amino acid has a codon of 5 nucleotides.
The answer is C. A catalyst speeds up the rate of a chemical reaction. However, it is not consumed during the course of the day.

Acomodation is the process in which the lens adapt to the distance of the object you look at.
During acomodation The lens changes shape and during the pupil reflex the pupils changes size so the answer is <u><em>C</em></u>

The cerebelum is not attached to the spinal cord, but to the brainstem through cerebellar peduncles
medulla oblongata is part of the brainstem and it is attached to the spinal cord so the answer is <u><em>B</em></u>

Insulin is a hypoglicemiant hormone that stimulates glycogenesis which is the synthesis of glycogen from glucose, hence the answer is <u><em>C</em></u>
<u><em>10.</em></u>
You get a fight or flight response which is mediated by adrenaline.<u><em> B</em></u>
<u><em>11.</em></u>
Adrenaline increases sweat production and decreases digestive activity so the answer is <u><em>A.</em></u>
