Answer:
Explanation:
Diagram included below.
1.) 4 chromosomes. Daughter cells are not identical due to recombination (i.e. crossing over).
1.) 2n=4
2.) Cells produced by meiosis are haploid. With just one chromatid.
Explain: Meiosis I separation of homologous chromosomes but sister chromatids stay together. Meiosis II sister chromatids separate, making haploid cells with non duplicated chromosomes.
3.) Germ cells have 46 chromosomes. Gametes have 23.
4.) Meiosis occurs in testes for men and ovaries for women. Mitosis occurs everywhere, basically any cell that isn't a reproductive cell.
5.) Recombination, genetic information is randomly shuffled. Events like crossing and the random orientation of homologue pairs make the possibilities endless. Remember sperm only gets half of the man's DNA, which half is random.
6.) After fertilization you get chromosomes from both mom and dad. The two haploid cells fuse and make a diploid cell.
I think it is the 3rd one because health problems at older age.
Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine (Figure 3). ... (Remember, DNA is almost always in a double-stranded helical form.)
The common difference between them is that they are all bacteria.
