Does during meiosis the 2n mother cells produces n daughter cells
liq [111]

Yes. During meiosis Diploid (2n) mother cell produces fou haploid(n) daughter cell.

Explanation:

  • Meiosis is also known as Reduction division.
  • It is type of cell division by which a diploid mother cell produces haploid daughter cell.
  • It is termed as reduction division because the number of chromosomes are reduced to half in daughter cell.
  • Meiosis occurs only in sex cells to produce gametes.
  • Significance of meiosis lie in the fact that it reduces the number of  chromosome into half and thus helps to maintain the chromosomal number of the species in the zygote after fertilisation .
  • Meiosis has two steps : Meiosis I and Meiosis II. There is a time gap between two steps, called interkinesis.
  • Meiosis I involves replication , crossing over etc.
  • Meiosis II is similar to mitosis however, no DNA replication occurs prior to meiosis II and the DNA content is thus halved in Daughter cell.

I need this today <br> How are the nitrogen atoms from proteins removed from our bodies?
Lorico [155]

Answer:

As in the liver, the first step is the removal of the nitrogen from the amino acid. However, muscle lacks the enzymes of the urea cycle, so the nitrogen must be released in a form that can be absorbed by the liver and converted into urea.

Why is the cell like a city?
devlian [24]

Answer:

The cell is basically like a city because there are different parts of the cell that work together to keep a system running, therefore incredibly similar to a cell. There are parts to the cell such as the vacuole which acts as the storage for a cell, like the storeroom or bank in the city, and the lysosome which cleans up and recycles for the cell in away, acting as the recycle center or such for a city. Just like these few cell parts, there are many other parts which each have their respective "role" to functioning as a "city", and for those reasons a cell is like a city.
