The True statements are.

Organisms in a population must compete for the resources as the resources are limited and the organism that compete and survives wins.

The best equipped organism survive which is known as the survival of the fittest.

Over the time due to challenges in the environment the beneficial variation takes place in the organisms and it spreads through the generations and then it gradually changes the whole population.

The false statement is Organism of the same species are equipped with the same survival skills.

The organism of the same species have some variation and because of this variation they compete and win against the other member of the same species.

finlep [7]

Answer:

The correct answer is e. Postzygotic barrier.

Explanation:

Different species can not mate and produce viable, healthy and fertile descendence, due to certain mechanisms of reproductive isolation.

These mechanisms involve different kinds of barriers that make it difficult for two different species to produce viable and fertile progeny.

One of these is the postzygotic barrier, which avoids the hybrid zygote to develope to adultness. In these situations, there is a mix of chromosomes that can not happen to meet or that they lack information.

There are cases in which the embryo dies, but some times the individual can reach some more advanced develope stages. If this is the case, in general, they can not survive because the organism is unhealthy. And if they reach adultness in good sate they can not leave descendence, as they are sterile.
