Answer:
Selectivity in choosing a mates
Geographic barriers separating subpopulations.
Explanation:
Selectivity in choosing a mates is a factor in which individuals can mate with each other. Some individuals tend to choose a sexual mates that posses some traits or characteristics that attract them to each other and because of the observable character, similar individuals attracted to each other mates.
Geographic barriers separating subpopulations is another factor that make similar organism or individuals to mates.
When there is geographic separations or demarcation between individuals in a species and they are separated from other subpopulations .. They tend to mate with each other in the same geographic location and cannot mate with other subpopulations that is outside their own geographic location. These is common in animals.

Answer:
True.
Explanation:
Rotenone is a broad spectrum pesticide and insecticide and is also considered as a non-selective piscicide.
The action mechanism of the rotenone has been described below -
It interferes with the electron transport chain which occurs in mitochondria of the cells. Here the transfer of electrons from complex I to the ubiquinone is inhibited by the rotenone. As a result, ATP formation with the help of NADH is also inhibited. When electron transport fails, oxygen in the cell is reduced to oxygen radical which further damages DNA and other components present in the mitochondria.
