Answer:
d. Lysine is replaced by tryptophan (nonpolar)
Explanation:
Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.
If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.
Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.
Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.

<h2>
PNS and SNS</h2>
Explanation:
Parasympathetic nervous system (PNS)
-
In the event that the blood pressure is increased because of any explanation, it is detected by the baroreceptor system
- The baroreceptor reflex invigorates is the part of the parasympathetic nervous system
- The PSNS causes reflation of veins, decreasing total peripheral resistance. It also decrease the heart rate
Sympathetic nervous system (SNS)
-
Heart rate and blood volume are regulated by the interrelated activities of the sympathetic nervous system (SNS) and the renin-angiotensin-aldosterone system (RAAS)
- The SNS is improperly dynamic in obesity and <em>hypertension</em> and plays a causal or permissive role in all types of chronic hypertension
