biology

Question 1

mitosis

Answer 1

a process where a single cell divides into two identical daughter cells

Question 2

stem cells

Answer 2

a cell with the unique ability to develop into specialised cell types in the body

Question 3

how does apoptosis give you a healthy life

Answer 3

maintains the balance of cells in the human body and is particularly important in the immune system.

Question 4

what causes errors in apoptosis

Answer 4

Viruses from many different families inhibit apoptosis of cells

Question 5

totipotent

Answer 5

stem cells that can divide into all cell types in an organism

Question 6

pluripotent

Answer 6

stem cells can divide into most, or all, cell types in an organism, but cannot develop into an entire organism on their own

Question 7

uniponent

Answer 7

can produce only one cell type but have the property of self- renewal that distinguishes them from non-stem cells

Question 8

multipotent

Answer 8

stem cells can differentiate into the various cell types in a family of related cells, such as blood cells.

Question 9

what is G1

Answer 9

the cell grows in preparation for DNA replication, and certain intracellular components,

Question 10

what are types of stem cells

Answer 10

embryonic stem cells.
adult stem cells.
induced pluripotent stem cells.

Question 11

embryo

Answer 11

the early developmental stage of an animal while it is in the egg or within the uterus of the mother

Question 12

stages of apoptosis

Answer 12

induction, early phase, mid phase and late phase

Question 13

What happens if apoptosis malfunctions?

Answer 13

self-reactive cells may be released into the body, where they can attack tissues and cause autoimmune conditions

Question 14

what happens in mitosis phase

Answer 14

a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells
