Questions1. Given there are 7 animal pairs of each kind loaded on to Noah’s Ark (A0 = 7), how many animal pairs of each kind could we expect in year 20 and in year 40?2. Suppose Noah loaded 500 kinds of animals on the Ark, for a total of 3500 animal pairs (A0 = 3500). In what year does the model predict that we reach 10,000,000 animal pairs total?
