Chlorine is added in the water treatment process because it kills off all of the bacteria and bad things inside of the water that may not be seen. It doesn’t necessarily “filter” it out, it’s just because the organisms living inside of it die because of the chemical element.

How does the body responds to transplants and how doctors are able to successfully perform transplants
riadik2000 [5.3K]

Answer:

The body naturally responds by rejecting the new organ because it is identified as a foreign object. Doctors use tissue typing to measure the compatibility of the antigens in the organ to that of the recipient. Another way doctors make sure the organs are accepted is through immunosuppressants that make the immune system does not attack the organ.

Explanation:

must include:

body rejects transplants because it recognizes them as foreign

lymphocytes attack the new organ

tissue typing measures antigens on tissue donor organ for compatibility

immunosuppressants disrupt the replication process of lymphocytes that produce antibodies and makes the immune system less effective

Dr. Brantz wants to use neuroimaging to detect which part of the brain is active when a person is lying. He asks half his partic
Katyanochek1 [597]

Dr. Brantz wants to test the part of the brain which is active while lying. For this purpose, he will need to make use of the fMRI (functional magnetic resonance imaging) technique. This technique is used for measuring the brain activity by the means of the detecting changes in the blood flow. The neural activation affects the cerebral blood flow, and this change can be noticed using fMRI.

Hence, the answer is 'fMRI'.
