Universe's average temperature and rate of expansion support the idea that it began as one super-dense and hot mass 13.8 billion years ago.
Answer:
a
) 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:
Roses
Explanation:
The scientific name of wild cherry is <em>Prunus avium</em> which means it belongs to the genus Prunus. Prunus genus is a part of Rosaceae family. Rosaceae is also called as rose family. It consists of around 91 genera of flowering plants. It contains herbs, shrubs and trees. They are found almost everywhere except Antarctica. They give rise to many important economical products like ornamental flowers ( roses, rowans, firethorns) and fruits ( cherries, peaches, plums ).
Liverworts and mosses are bryophytes and pine tree is gymnosperm whereas rose and wild cherry are both angiosperms. They both are also part of Rosaceae family hence they share some characteristics and are closely related in comparison to other options.
