Q1
Discuss one example, based on your day-to-day observations, showing how loss of one species may lead to the extinction of another.
Q2
A species area curve is drawn by plotting the number of species against the area. How is it that when a very large area is considered the slope is steeper than that for smaller areas ?
Q3
Is it possible that productivity and diversity of a natural community remain constant over a time period of, say one hundred years?

In very large areas, the number of species is much more that is why the curve is much steeper. This is because the larger area has more, food availability and other resources, so obviously more species may thrive.

  1. {"H) oi","cary) MYOGENIC MECHANISM","his An increase in blood pressure will tend to stretch the afferent arteriole, which would be expected to increase the blood flow to the glomerulus. The wall of the afferent arteriole, however, responds to stretch by contraction, this reduces the diameter of the arteriole, and therefore causes increase in the resistance to flow. This myogenic mechanism, thus, reduces variations in flow to the glomerulus in case of fluctuations in blood pressure.","05. MICTURITION"}

Like all viral pathogens, severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2 (I know, how topical), requires a cell surface receptor in order to invade a given host cell. For SARS-CoV-2, this receptor is actually the enzyme Angiotensin Converting Enzyme 2, or ACE2. ACE2 is responsible for downregulation of the Renin-Angiotensin-Aldosterone System by deactivation of Angiotensin II. Explain the RAAS in detail, including the roles played by kidneys and the lungs, and then explain what effects using recombinant human ACE2, or rhACE2, to treat acute respiratory distress syndrome could have on blood pressure.
