O átomo
Explanation:
O átomo constitui a molécula e tudo é feito de moléculas
Answer:
D In Prophase I the chromosomes crossover, in Prophase II they do not crossover
Explanation:
Meiosis is a type of cell division in which four daughter cells, which are genetically different from one another, are produced. The daughter cells have their chromosomal number reduced by half. Since, the meiotic process aims at producing haploid gametes, it occurs in a series of two-division steps viz: meiosis I and meiosis II.
Meiosis I involves the separation of homologous chromosomes into two daughter cells while the meiosis II involves separation of chromatids to make four daughter cells. One major difference between meiosis I and meiosis II is that in the PROPHASE of meiosis I, a unique process called CROSSING OVER occurs but does not occur in meiosis II (as seen in the attached image).

Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes)
Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical.
