Answer:
a. Midwest has few sources of acid rain-forming pollutants.

Answer:
Metaphase
Explanation:
The M phase of the cell cycle is the phase during which the nuclear content and cellular content is distributed. The distribution of the nuclear content takes place in four phases: prophase, metaphase, anaphase and telophase.
The homologous chromosomes are aligned at the equatorial plate during the metaphase after which the chromosomes separate. The phase during which the separation of the chromosomes takes place is known as anaphase so the phase before the anaphase is the phase during which the chromatids are not separated that is the metaphase.
Thus, metaphase is the correct answer.
