help me fast plzzzz
Answers
Answer ( 1 ) :-
Mitosis involves the division of body cells, while meiosis involves the division of sex cells. ... Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis. Daughter cells resulting from mitosis are diploid, while those resulting from meiosis are haploid.
Answer ( 2 ) :-
Anaphase begins when the duplicated centromeres of each pair of sister chromatids separate, and the now-daughter chromosomes begin moving toward opposite poles of the cell due to the action of the spindle. ... At the end of anaphase, a complete set of chromosomes has assembled at each pole of the cell.

Significance of Mitosis:-
It is responsible for a definite shape, and proper growth and development of an individual. It maintains the constant number of chromosomes in all body cells of an organism. In plants, mitosis helps in the formation of new parts and the repairing of damaged parts.
Answer ( 4 ) :-
The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA.
Answer ( 5 ) :-
Cytokinesis is the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis.
Answer ( 6 ) :-
Cytokinesis occurs in mitosis and meiosis for both plant and animal cells. The ultimate objective is to divide the parent cell into daughter cells. In plants , this occurs when a cell wall forms in between the daughter cells. In animals , this occurs when a cleavage furrow forms.
Answer ( 7 ) :-
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

Answer ( 8 ) :-
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell divides twice to form four daughter cells.
