There are many factors that determine what a predator will prey on. For instance if the predator is starving or if they are hunting in a pack. Predators will usually prey on animals that are easiest to be captured without using too much energy. The sick, young, old, small and unaware animals will often times fall prey since they are easiest to be caught. Predators don't necessarily prey only on the ill/ injured. Sick prey may be overlooked because their bodies may not provide the necessary sustence for the predator and others it may be feeding. Healthy large slow moving animals may be difficult to kill but the payoff is greater, especially if a pack is involved.
Correct answer: D). DNA technology can increase genetic diversity by producing more variant alleles.
The genetic diversity can be increased by the mutation that creates new alleles in the population. The recombinant DNA technology enables the joining of DNA from the two or more than two sources that allow changing the genetic composition of the living organism. The genetic diversity helps the population to adapt to the changing environment.
Hence, the correct answer would be option D.

A low to moderate fever, when a low to moderate fever, when allowed to run its course, can be beneficial. fever can promote interferon activity.
