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.

What is the patellar tendon reflex?
- The patellar tendon reflex refers to a kicking-like motion produced by the extension of the knee joint upon the ipsilateral stimulation of the patellar tendon.
- The reflex is thought to play a role in maintaining balance
- Striking of the patellar tendon with a reflex hammer just below the patella stretches the muscle spindle in the quadriceps muscle.
What is pathology?
- Pathology is the medical discipline that provides diagnostic information to patients and clinicians.
- It impacts nearly all aspects of patient care, from diagnosing cancer to managing chronic diseases through accurate laboratory testing.
- The sharp tap on the tendon slightly stretches the quadriceps, the complex of muscles at the front of the upper leg
- In reaction these muscles contract, and the contraction tends to straighten the leg in a kicking motion.
- Exaggeration or absence of the reaction suggests that there may be damage to the central nervous system

The immigration rate and the emigration rate are equal in case of a stable population.
Option A
<h3><u>Explanation:</u></h3>
A stable population is defined as the number of individuals residing in an environment with a limited resources and the number of individuals residing more or less remains constant. In case of a population, there are different factors which tends to divert the population out of the stability, like immigration or emigration. Immigration is the addition of individuals to the population from outside which increases the population, and emigration is the loss of individuals which decrease the population. In case of a stable population, the number of immigrants and emigrants remain more or less same, which maintains a stable population.
