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 ❤️

Based on your knowledge of how the greenhouse effect works, why does the level carbon dioxide affect the global temperature?

miv72 [106K]

Explanation:

Carbon dioxide and other greenhouse gases in the atmosphere prevents long wave radiation from leaving the earth and in the process, it raises global temperatures.

Greenhouse gases helps to maintain the fair balance in temperature on the earth surface.
They keep the temperature of the earth in balance by preventing it from losing all of the heat it gains.
Radiation from the sun reaches the surface as short wave radiations.
When they get absorbed and re-emitted, they produce long wave thermal radiations.
In the atmosphere, the radiations are cut off and causes warming due to their interaction with greenhouse gasses there
When the amount of these gases in the atmosphere become more than normal, more heat becomes trapped.
This leads to an anomalously high surface temperature on earth.
