It is important to know a person's blood type before transfusing blood into the body to whether the blood which is going to be transfused into the person is compatible or incompatible. Only the compatible blood can be transfused. If incompatible blood is transfused to the person, it may cause death due to the clumping of blood.

Because if you give them the wrong kind of blood, then their body will react to the different blood cells like they were bacteria or a virus.

1. Why does the moon appear to change throughout each month? *
andrey2020 [161]

Answer:

C

Explanation:

As the Earth moves in relative to the moon the Earth blocks part of the sun from the moon causing only parts of the moon to light up. This BEST answers the question because B is not accurate because it doesn't describe why we actually SEE it. A might be true but it is not the BEST explained.

Hope this helps! (^-^)

Large changes in temperature and acidity interfere with enzyme activity by _
ankoles [38]

Answer: Denaturing

Explanation: Enzymes are made of amino acids that are linked by bonds, amongst those bonds are hydrogen bonds that are very weak. High temperatures and low pH(acidity) breaks those bonds changing the molecular conformation of the enzymes. That way they denature and loss the ability to perform their functions. High temperatures and acidity alter the structure of their active site preventing the substrate from binding to them. While high temperatures denatures enzymes, low temperature renders them inactive.
