) 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.
Answer:
A. soil excavation and disposal. thank you for the answer :)
Answer:
1. Each trophic lvl would decrease in population.
2.The species will have to adapt by finding new food and most likely a new area to live if the invasive species is that bad.
The DNA base sequence carries the information a cell needs to assemble protein and RNA molecules.
Here is the answer to the given question above. Vitamin D is the vitamin that is essential in <span>managing calcium in your blood, bones and gut and helps cells all over your body to communicate properly. This vitamin D is being absorbed through the skin once it is exposed in sunlight. After that, the body would undergo some chemical processes. This is the reason why it is necessary in the formation of bones. Hope this answer helps.</span>
