When a single cell undergoes many mitotic divisions in the nucleus, producing many daughter cells, it has conducted B) Multiple fission.
Multiple Fission is a type of asexual reproduction in which the parental body divides into many daughter cells simultaneously during the unfavorable conditions to increase the chances of survival of daughter cells.In this, the reproductive unit is whole parental body.
Hope this helps :)
Answer:
( Going from left to right )
- Prophase -
- Telophase & Cytokinesis -
- Anaphase -
- Metaphase -
Explanation:
Prophase - Chromatin condenses making the chromosomes visible.
the nuclear envelope breaks down - makes it look like it has butterflies
Remember: The "PRO-phase" gets -butterflies- when it's about to start a race, but he lost so he starts to have a -break down-.
Metaphase - The chromosomes become aligned at the "center" or equatorial plane.
Remember: metaphase in Greek means "between" and "stage" and during this stage, the chromosomes stop moving back and forth, and also there are kept in the middle of the cell !!
Anaphase - sister chromatids separate and the resultant daughter chromosomes move toward the poles.
Remember: Sister Anna has a twin they both move out of their home and separate. One moves to the north pole and the other lives in the south pole.
Telophase - Daughter chromosomes reach the poles and form two new nuclei.
Remember: Anna and her twin settle in their new homes and both of the sisters throughout the year have two children or "nuclei" each, and also call each other on the "telephone" almost every day. :)

Selective permeability, made possible in cells by the phospholipid bilayer that makes up the plasma membrane, is basically monitoring and regulating what can and can't enter the cell. It is carried out by a series of membrane proteins that act as channels to polar molecules, opening to allow them in and closing to prevent their entry. This is possible because the hydrophobic tails of the phospholipid molecules repel polar molecules and so prevent their entry unless through a channel.
<span>Mendel included the following in his hypothesis: A pair of factors (known as genes) control traits. One gene comes from each parent for every trait. Each trait is passed from generation to generation. When gametes are formed, genes separate. If there are two unlike genes, one may be seen while the other is hidden. The inheritance of each trait is determined by units or factors that are passed on to descendants unchanged, and individual inherits one such unit from each parent for each trait, a trait may not show up in an individual but can still be passed on to the next generation and also the genes for each trait segragate themselves during gamete production.</span>
