Answer:

1. Life cycle of a cell starts from

G1 phase - S phase (synthesise phase) - G2 phase - mitosis.

2. By mitosis bcoz it restore nucleo cytoplasmic ratio means ploidy of cell remain same.

3. Bcoz of transformation of normal cells into cancerous cells by Carcinogens present in tobacco.,drugs .etc

4 mitosis occurs in plants animals

Binary fission occurs in bacteria and other single celled organism.

Both give rise to two daughter cells.

5.sex cells (n) are produced by meiosis from gamete mother cells(2n).

6.in meiosis ploidy of cell become half

Means diploid cell form haploid cells

And 4 haploid daughters cells are formed.

In mitosis, ploidy of cell remain same

Means haploid form haploid and diploid form diploid.

1 cell form 2 daughter cells.

Hope this helps you.. Frnd ❤️

Answer:

$23$

Explanation:

Use: $(a+b)^2= a^2+2 ab+b^2$

Square both sides:

$\Big( x+\frac{1}{x}\Big)^2=5^2\\\implies x^2+2(x) \Big(\frac{1}{x}\Big) +\frac{1}{x^2}=25\\\implies x^2+\frac{1}{x^2}=25-2=\boxed {\color{red}{23}}$

Answer:

Option D

Explanation:

The species probably has a small genome that is made up just two linear chromosomes such as that seen in the Jack jumper ant genome. It containing exactly two linear chromosomes could be a single pair of homologous chromosomes thus maybe indicating the cell is probably diploid but this is not enough to conclude on the ploidy.

A vacuole takes up majority of a plant cell when full (it's job is to hold the liquids of the cell and plants require a lot of water to function).
