The two cells formed at the end of meiosis i have chromosomes that are

The correct answer is - Genetically different from one another and also different from the cell that entered meiosis I.

Explanation:

Meiosis is the process that ensures the transition of the 2n chromosomes to the haploid phase of the organism. Meiosis follows a stage of DNA replication and performs 2 successive divisions, In which the second division is not preceded by replication of DNA.  

During meiosis, Chromosomal mixing takes place that provides genetic diversity between the cells that formed at the end of the meiosis first. During prophase I the chromosomal mixing and the crossing over takes place.

Thus, the correct answer is - Genetically different from one another and also different from the diploid cell that entered meiosis I.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

"a.) well–developed vascular system."
