) Anaphase usually ensures that each daughter cell has the same number of chromosomes as the parent cell.
Explanation:
- <em>Mitosis</em>: After DNI duplication and condensation, Sister chromatids of the chromosome, are held together in the equatorial plane until they reach the <em>Anaphase</em>, during which certain enzymes are activated to break the bonds among them and the <em>separation of the chromatids occur</em>, migrating to the opposite poles.
- <em>Meiosis</em>: Gamete formation involves the random and independent segregation of the alleles. After crossing-over, homologous chromosomes which are located in the equatorial plane, get separated. During <em>anaphase I</em> occur the independent <em>separation of homologous chromosomes</em> that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair. During <em>Anaphase II</em>, enzymes are activated to break the bonds that keep together the chromosome and <em>separate the sister chromatids</em>.
Anaphase (Mitosis) and Anaphase II (Meiosis) are very similar. By separating sister chromatids, anaphase is responsible that each daughter cell has the same number of chromosomes as the parent cell. Some mutations or alterations in the chromatids migration process might occur during anaphase, such as non-disjunction, which is a defect or mistake in the separation of the homologous chromosomes during anaphase of the meiotic division.
Unlike Prokaryotic cells, eukaryotic cells can actually have different roles instead of the same cell over and over. This, obviously, leads to more complex creatures. Basically, a theory (now proven correct) called The Big Gulp explains how we took in small prokaryotic organisms to do the roles for us. For example, mitochondria makes proteins so we do not have to waste our own organisms protein.
The answer is geological; biological diversity evidence. His hypothesis clarifies that natural assorted qualities come about because of the relatives of nearby or transient ancestors getting to be noticeably adjusted to their differing surroundings. This clarification can be tried by looking at present species and nearby fossils to see whether they have comparable structures, which would show how one is gotten from the other.

Answer:
Transmission electron Microscope
Explanation:
It produces thin slices of photography and extremely tiny things. The disadvantages are that its expensive, and you cannot test living things with it, its also massive
