Answer: c.Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Natural selection is the differential survival and reproduction of individuals because of differences in the phenotype. Phenotypic characteristics favors the survival of some organisms in the population better than others. Example given by Darwin population of colored beetles green and red belonging to same species. Green ones mimic the color of grass not noticed by birds but red ones were noticed and eaten by birds. This is the selection by nature for better suited individuals. Green color gave the survival advantage to these beetles which is a phenotypic characteristic therefore, they will produce more offsprings than the red ones and also pass on the phenotypic trait to their offsprings.
<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
