Question

out the tally?
8. An engineering construction firm is currently working on
power plants at three different sites. Let A denote the event
that the plant at site i is completed by the contract date. Use
the operations of union, intersection, and complementation
to describe each of the following events in terms of A1, A2,
and Az, draw a Venn diagram, and shade the region corre-
sponding to each one.
a. At least one plant is completed by the contract date.
b. All plants are completed by the contract date.
c. Only the plant at site 1 is completed by the contract date.
d. Exactly one plant is completed by the contract date.
e. Either the plant at site 1 or both of the other two plants
are completed by the contract date.​

Answer 1

Answer:

The amount of the filtrate formed by the kidneys per minute is called the glomerular filtration rate (GFR). This in a healthy individual is approximately 125 ml/ minute, i.e., 180 litres per day. Three important intrinsic mechanisms provide autoregulation of GFR.

1. Myogenic mechanism.

2. Juxtaglomerular mechanism.

3. Neural control.

2. Juxtaglomerular mechanism: It is an efficient mechanism for regulation of GFR. It is formed by distal convoluted tubule and him afferent arteriole at the location of their contact. Its cells secrete enzymes like renin that modulate blood pressure and thus renal blood flow. This regulates GFR.

So, the correct answer is 'JGA, DCT, Afferent arteriole, Renin'.
