I do believe that it is C. crossing over :) I hope that is correct, it seems like the only plausible answer.
Answer:
The time required for the colony to grow two million bacteria is 29.22.
Explanation:
Time required for the colony to grow can be calculated by the following equation:

Here t is time, N = 2 million (require bacteria population).

t ≈ 29.22
Time taken by bacteria to grow is 29.22.
Biological diversity is the variety of species in a given area. If a new species is added there are more species and therefor greater biological diversity and if one goes extinct there are less species and therefore less biological diversity.
