1. Reply. UWorldScience. • 2 yr. ago. AP Bio is challenging in that it requires memorization of a significant amount of material, but more importantly, requires analysis and application of that information in a variety of contexts. For that reason, Unit 6 (gene expression and regulation) tends to be most difficult for many students.

Correct answer: r = k [A] [B]2. Explanation: When the concentration of A stays the same but the concentration of B doubles, the rate quadruples, showing a second order rate law based on B. When the concentration of A doubles and B stays the same, the rate also doubles, showing a first order rate law based on A.
