Hints for Problem #1

    A. How many bacteria will be present at the end of 5 hrs?

    B. How much N is left in the medium? Enough for the bacteria to keep doubling?

    C. What is the limiting factor? Time or raw materials?

Hints for Problem #2:

    (i) Where will the N atoms go? Will they replace old N atoms already in molecules? Be used to make new molecules?

    (ii) If you are not sure which of the complex molecules contain N, check out your text or handouts. (What is the "R" in phospholipids?)
