Which type of growth occurs when population growth slows or stops after a period of exponential growth?
a) decreasing
b) exponential
c) linear
d) logistic

The answer is D. A logistic curve is S-shaped. It begins with the lag phase, then log phase, then the stagnant phase. The lag phase is when the individuals are too small a population and are acclimatizing to the environment. The exponential phase is when they begin to divide and their population doubles in each generation. Then the stagnant phase is when the population is overcrowded and the resourc3s are limited when the carrying capacity is reached.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion
