Answer:
Cells must divide to perform functions such as growth of the organism, replacement of damaged or old cells, and asexual reproduction in some organisms.
Explanation:
The separation of the sister chromatids occurs during Meiosis II because during Meiosis I occurs the separation of homologous chromosomes.
<h3>What is Meiosis I?</h3>
Meiosis I is the first cell division stage during the meiosis, which is a process that has as objective to generate four daughter cells having half the genetic material.
Meiosis has two successive rounds of cell division which are known as Meiosis I and Meiosis II, and these major stages can also be classified into sequential substages (i.e., Prophase, Metaphase, Anaphase, and Telophase). Before Meiosis, the genetic material is duplicated during the synthesis (S) phase of the cell cycle.
Homologous chromosomes are composed of two sister chromatids that separate during Anaphase II (Meiosis II).
In conclusion, the separation of the sister chromatids occurs during Meiosis II because during Meiosis I occurs the separation of homologous chromosomes.

It's the monthly cycle which occurs in female during which unfertilized ovum dies and pass out through vagina in the form of blood.
The correct option is B.
Communication between cells can be inter communication or intra communication. Inter communication refers to a type of communication in which message is transfer from a near or distant cell to another cell, while the intra communication form of message transfer is one in which a message is been passed across within a single cell.
In the option B above, a single cell is involved and that is an example of an intra communication. The other options are example of inter communication.
It produces lymphocytes, is important for T cell maturation (T for thymus-derived). The spleen is an organ in the upper left abdomen, which filters blood, disposes of worn-out red blood cells, and provides a 'reserve supply' of blood. It contains both red tissue, and white lymphatic tissue. Hope that helped!
