Explanation:
A urine concentration test measures the ability of the kidneys to conserve or excrete water.
A urine specific gravity test compares the density of urine to the density of water. This quick test can help determine how well your kidneys are diluting your urine. Urine that's too concentrated could mean that your kidneys aren't functioning properly or that you aren't drinking enough water.
Urine is concentrated in the final stages of its production: water is absorbed, in excess of solute, from the collecting ducts and into the vasculature of the medulla, thus increasing the osmolality of the collecting duct fluid and thus the osmolality of the urine that emerges from the collecting ducts.

Answer:
The correct answer is a. True
Explanation:
The resting heart rate for a normal adult is between 50 to 90 beats per minute. Resting heartbeat below 50 is possible in persons who are very good athletes. A more cardiovascular fitness is seen in good athlete and they can have a resting heart rate near to 40.
If a normal resting heart rate falls from 60 that condition is known as bradycardia. Mostly old people are more prone to it. Tachycardia is a medical condition in which a person's resting heartbeat reaches above 100.
Both the condition bradycardia and tachycardia shows the problem related to heart and require medical attention.
Organ rejection takes place when your body is subjected to a new organ which is a foreign object and attacks it.
<h3>What do you mean by Graft rejection?</h3>
Graft rejection may be defined as a process in which a transplant recipient's immune system attacks the transplanted organ or tissue.
Xenograft shows high rejection. This is because it involves the transplantation between genetically distinct members of different species.
The process of organ rejection is initiated by T cells which perform the role of the recognization of a transplanted organ.
If these T cells are activated, it may lead to organ rejection by undergoing clonal expansion, and differentiation of the effector cells, which together lead to the obliteration of the tissues.
Therefore, organ rejection takes place when your body is subjected to a new organ which is a foreign object, and attacks it.
