Answer: B, Meiosis I
Explanation:
During meiosis I, genetic material halves, and you get 2 haploid cells (n) from a diploid cell (2n). Those divide again during meiosis II to form 4 different haploid cells.
DNA replicates during interphase and starting at meiosis I, 2n homolog chromosomes attach to form n tetrads. Those tetrads align in the cellular equator during metaphase I and then separate, moving to opposite poles during anaphase I. Each cell formed receives a copy of each chromosome and then divides in a process similar to mitosis during meiosis II.
Answer:
Both desert and tundra plants grow and flower quickly in the short growing season.
Desert plants have special structures that allow them to trap and store water.
Tundra plants grow low to the ground to stay out of the cold and dry wind.
