Answer:

Rh+ blood can be given only once to a non-sensitized person who is Rh- because it develops antibodies and after one exposure blood will be rejected.

Salsk061 [2.6K]

Answer:

The regulation of the cell cycle helps in wound healing as well as replacing the lost cells by division. Thus, options B and C are correct.
