For the calculation I got 0.005 for the leaves wilting I put water can't be transported through the xylem so less photosynthesis and the leaf dries up.

for the sentences I said ABT how DNA isn't in the nucleus in bacteria that it floats in cytoplasm or in inside the plasmid. then I put that mutations just come naturally because it isn't the antibiotics that causes it. then that the mutation causes a change in the bacterias antigen. idk if I'm right tho
