I really need help on this. If you help I will give brainliest.
And free points next.
Plz.
As the concentration of molecules outside of a cell increases, more molecules will enter the cell because —

A) the molecules are moving down their concentration gradient

B) the molecules are moving from an area of low concentration to an area of high concentration

C) energy is available to move them using active transport

D) they have reached dynamic equilibrium

I HAVE NO CLUE Plz help.

Dna has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. one aspect of dna that allows it to accurately store genetic information is the base pairing from chargaff\'s first rule of the four nucleotide bases. if the c content of a dna molecule is 22%, what are the percentages of the remaining bases?
