Question 1

Cell cycle

Answer 1

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA to produce two daughter cells

Question 2

Mitosis

Answer 2

In cell biology, mitosis is a part of the cell cycle when replicated chromosomes are separated into two new nuclei.

Question 3

Differentiate

Answer 3

make or become different in the process of growth or development.

Question 4

Stem cell

Answer 4

It can become any type of cell that is required

Question 5

Cloning

Answer 5

Cloning is having cell exactly the same as other cells and making huge numbers of them cels

Question 6

Ygote

Answer 6

a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.

Question 7

Embryonic stem cells

Answer 7

They form all specialised stem cells in the body

Question 8

Therapeutic cloning

Answer 8

Making adult cells clone it is a very difficult process

Question 9

Cell

Answer 9

cell is the smallest unit of life that can replicate independently. The study of cells is called cell biology. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.

Question 10

Dna

Answer 10

Deoxyribonucleic acid is a thread-like chain of nucleotides carrying the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses

Question 11

Differentiation

Answer 11

the action or process of differentiating or distinguishing between two or more things or people.

Question 12

Spinal cord

Answer 12

The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. The human spinal cord is protected by the bony spinal column shown to the left. The spinal column is made up of bones called vertebrae.

Question 13

Heart

Answer 13

a hollow muscular organ that pumps the blood through the circulatory system by rhythmic contraction and dilation. In vertebrates there may be up to four chambers (as in humans), with two atria and two ventricles.

Question 14

Kidney

Answer 14

The kidneys are two bean-shaped organs found on the left and right sides of the body in vertebrates. They are located at the back of the abdominal cavity in the retroperitoneal space.

Question 15

Insulin producing cells

Answer 15

The primary function of a beta cell is to store and release insulin. Insulin is a hormone that brings about effects which reduce blood glucose concentration. Beta cells can respond quickly to spikes in blood glucose concentrations by secreting some of their stored insulin while simultaneously producing more.
