I suggest that if you don't know this then you should not be studying biology and our help with your homework will only temporarily disguise your lack of interest.

You will have to define what you mean by a unit. Otherwise, the answer must be ''an atom''

...or a quark!

I'm glad you two got there first. What I had in mind is bigger, (well at least in my case), than a quark . . . or an atom for that matter!

This is one of the first things one learns in science. I’m surprised you don't know the answer.

Bragging, Mibn? Obviously the weather's warmer in your neck of the woods than it is round my way!! ;-)

I think vascop's given the best clue to the answer I think your teacher may be looking for
