Answer:

Statements thar are true:

Some organisms have phenotypes that make them better increase chances of reproduction.

Natural selection continues to occur even today

Phenotypes found In the most successful members of a species become the most prevalent after several generations.

Explanation:

It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.

Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.

Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.

A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.

Answer:

For natural selection to occur, it is true that there must be genetic variation in the population.

Explanation:

According to evolution, natural selection implies the changes that occur in the genotype of a species, due to the effect of environmental factors, and which guarantee its survival through adaptive evolution.

For natural selection to occur, three fundamental conditions must exist:

A trait that can be inherited from one generation to another.

The trait is subject to variability between subjects of the same species.

Genetic variability can determine the possibility of reproductive success and survival.

Therefore, a necessary factor for natural selection to occur is that genetic variability exists in the population.

A researcher is comparing the species diversity of two islands. Both islands are roughly equal in size. However, one island is m

Nastasia [14]

Answer:

higher than; the same as.

Explanation:

The Mac Arthur and Wilson theory of island bio geography states that island species is determined by the size and distance of island from the mainland. The island of large size and less distance accumulate more species.

The researcher compare the species of two island. According to the Wilson, she can determines that the S value is higher for the island located closer to mainland than from the island located far away. The extinction rate of both the islands are same.

Thus, the correct answer is option (e).
