You tested that a pineapple pie has 4 million of bacteria V in it. The baker did not wash his hands and has probably contaminated the cream initially with 800 cells of bacteria V. He also forgot to refrigerate the pie after baking. A. if the pie was made 5 hours ago, how many generations have occurred (round off final answer to nearest whole number)? B. how long is each generation (use final answer of A for number of generations)? C. using the computed generation time, how many cells of bacteria V would be present 10 hours after the baker has contaminated the pie if it remains unrefrigerated?

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
