biology help urgent

Is the answer C? because that is what i got.

how did u do it

Basically, the x-axis shows the change in length after being in the solution. If there is no change in length, the ratio of initial length to final length will be 1.00 (If something starts at 1cm and ends at 1cm, the ratio is 1:1)

If something has the some water potential as the plant, there will be no net movement of water in or out so the length with remain the same as nothing is moving in or out to stretch or shrivel it. Because of this, you read across from the x axis where it says 1.00 and then read down to find the concentration where there is no change in size and therefore no difference in water potential.

I'm doing A2 biology at the moment so if you need anything explaining I'll do my best.

Surly it would have to be sample 3 because uracil is (U) found in RNA and bonded to A (adenine) in DNA. As in DNA thymine (T) is replaced by Uracil in RNA, therefore sample 3 is Adenine as it matches 25 each i.e base 3 as it has 25 matching uracil as well.
