Evgesh-ka [11]

Correct answer: D

A pollen is where male gametes are produced and so the number of chromosomes, as we are talking about gametes, is n. This means that the grain of pollen will only have a copy of each gene, and therefore only one allele for each gene - one S, and one T or t. So, the possible combinations are ST and St.

zhannawk [14.2K]

The primary driving force that stabilizes lipid bilayers is the formation of hydrophobic bonds between fatty acid chains in phospholipids and protein.

The cell membrane is made up of phospolipid bilayer with proteins embedded in between

Lipid bilayer is the structure present in the biological membrane. It consist of two layers of lipids with hydrophilic end facing each other and hydrophobic end facing the outer side.

the inner layer has both the hydrophobic end of the lipid molecules facing each other and bonded by hydrophobic bond van der waals forces.

The outer molecules are bonded with the protein molecules through hydrophilic bonds called hydrogen bonds.

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 ❤️
