When plasma is transfused into a person, why is blood type not a concern?
Dvinal [7]
Blood type is not a concern when transfusing plasma from person to person because the plasma does not contain red blood cells. when things such as organs or blood are given to people (contain red blood cells), they must match the blood type of the person receiving these things so that there is a smaller chance of the person rejecting the organs, blood, etc. due to plasma not having red blood cells, we do not need to worry about the body rejecting it.

Medicines are often administered in pill form. In many cases, the active ingredient of the pill (the drug) is joined to another
Natasha_Volkova [10]

Answer:

Option B, ionic bonds; salt

Explanation:

All medicines either in the form of pills or liquid interact with our body by forming a bond with target specific receptors. For instance if a pain killer is taken then it shall form bond with receptors produced by pain and inflammation

So medicines are basically chemical which interact with biomolecules such as enzymes, nucleic acid, hormones, ions etc. by forming ionic bond, hydrogen bond, van der wall force etc. in the active site of enzyme.    

These salt molecule remain stable in normal conditions but as they come in contact with digestive system of the body (with different pH) they release the drugs

Hence, option B is correct
