In human cells, the four nitrogen bases that make up the genetic code are shared witha)primates only. b)mammals only. c)all eukaryotes, but no prokaryotes.  d)all living organisms.

I believe the answer would be D.

The four bases, Adenine, Guanine, Cytosine, and Thymine, are found in all DNA. This means, that no matter what, everything will have these four bases.

A is incorrect because all cells will have the four bases because all cells have DNA.

B is incorrect because, as I stated before, all cells will have the four bases because all cells have DNA. (This also includes plants as well.)

C is incorrect, because prokaryotes have DNA as well, so they have the four bases.

Swating at a bee and it stings

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.

Sorry  i don't understand can you rephrase that
