Can somebody give me the answer for these...

labwork [276]

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 ❤️

If the environment outside a cell is hypertonic, how will the cell maintain homeostasis?

USPshnik [31]

Answer: Water will move outside of the cell.

Homeostasis is the ability of the cell to maintain the state of balance despite of changing external environmental conditions. Osmotic pressure is the hydrostatic pressure of water across the cell membrane. Tonicity is the measurement of this pressure. If the concentration of solutes on both sides of the membrane is equal then water will not move across the membrane. Osmotic pressure maintains the homeostasis of the cell. In hypertonicity osmotic pressure of the solution outside the cell is higher than the inside the cell. The water inside the cell will exit the cells in order to equalize the osmotic pressure on both sides, causing the cells to shrink.
