A male bison charging another male bison is an illustration of which behavior?.
alukav5142 [94]

Two bison fighting each other shows the competitive relationship between both of them as they both belong to the same species and can fight for territory, food, resources, reproduction and many others factors.

Therefore, the Bison charging shows competitive relationships among the same species.

In-vitro fertilization: Pros: Allows people who couldn't have children to do so, increases knowledge and knowledge is good.Cons: Expensive (really expensive), can lead to overpopulation (minor), can be done irresponsibly (minor as everything can be).

It is mistakenly believed that the rapid evolutionary changes of punctuated equilibrium are the result of some mechanism of evol
netineya [11]

Answer: Natural selection can be defined as the differential survival and reproduction of members of the population of a species that have suitable traits to survive in a population of species.

Explanation:

The punctuated changes in the population of species have been found inordinately faster in the geological time scale, but changes per-generation have been relatively slow. Also, the rate of evolution in such a population is also slow. The punctuated changes in the population are because of evolution but the per-generation changes are the outcomes of the natural selection, in which only the beneficial traits are passed from one generation to another.
