Choose examples to support your reasoning. Select all that apply. An increase in temperature may select against cold-adapted genotypes. A predator not eating a bright colored prey again because the previous time the taste was unpleasant. An increase in a population of one species may case the extension of another species with the same food ration. An introduction of a new food resource into the environment may cause a new species to appear. An introduction of a new species of predator may cause the evolution of new defenses in some prey species.

An increase in a population of one species may case the extension of another species with the same food ration.

An introduction of a new food resource into the environment may cause a new species to appear.

An introduction of a new species of predator may cause the evolution of new defenses in some prey species.

Explanation:

An increase in a population of one species causes the extension of another species with the same food preference because the high population specie eat all the food and no food source is available to the other  organism.  An introduction of a new food resource into the environment may cause a new species to appear due to availability of the type of food.. An introduction of a new species of predator may cause the evolution of new defenses in some prey species which helps them in their survival.

Metaphase I  is the correct answer.

Explanation:

Metaphase I phase of meiosis are tetrads of homologous pairs lined up along the center of the cell and attached to the spindle fibers.

Meiosis is a type of cell division where chromosome number gets reduced by half and it produces four haploid cells.

meiosis comprises the steps of meiosis I and meiosis II

In the metaphase I the tetrads align themselves at the metaphase plate whereas, in metaphase II chromosomes align up separately along by the metaphase plate.

Anaphase I chromosomes separate and in Anaphase II sister chromatids of every chromosome get separated and they move towards the opposing poles.

Thus the correct answer is Metaphase I.
