Answer:
To regulate water balance in the body
Explanation:
The kidneys are two bean shaped renal organs which perform a host of functions for the body such as regulating fluid balance, filtering minerals from the blood etc. Among their functions is the regulation of water balance in the body through the antidiuretic hormone.
When an athlete completes a physical activity and sweats a lot, the kidney reacts to the loss of water by sweat by adjusting urine output causing the body to produce lower and more concentrated urine.
I believe the correct answer to the question is D. This answer choice makes the most sense given the context. Also, since RNA is less stable than DNA, it mutates more often.

17. The SI unit for force is N.
18. When an Unbalanced force acts upon and object, the object will change speed and/or direction of motion.
19. Average speed is the speed averaged over a span of time. Instantaneous speed would be the speed at any given instance during that span of time.
20. Acceleration= (final velocity - initial velocity) / time
Final velocity= 0 m/s
Initial velocity= 25 m/s
Time = 40 sec.
So, acceleration (0 - 25) m/s / 40 sec.
Acceleration = -0.625 m/s^2
Answer:
When blood glucose level rises beyond the threshold levels, the pancreas secrets hormones insulin. The latter ensures entry of glucose into the cells through Glut transporters for cellular utilization, therefore reducing the blood levels., and promotes storage as glycogen in the liver and muscles.
How ever if the glucose levels drops below the set point, an hormone glucagon is also produce by the pancreas to cause the liver o withdrawal and breakdown glucose storage as glycogen back to glucose thus raising the blood glucose level back to the normal levels.
This is an example of negative feedback mechanism, because the increase in the input levels (blood glucose levels) brings about a counter mechanisms (insulin secretions)as output , to reduce the elevated levels by promoting entry into the cells,, thus bringing the levels to threshold levels.
Thus insulin is acting in a negative feedback mechanism to control blood glucose levels
