Answer 11

Messy cell death/Necrosis

Question 12

A typical example of a messy cell death is….

Answer 12

A scab

Question 13

What type of cell death is when cells shrink, not disturbing nearby cells, they breakup into smaller bubbles and nearby cells pick up broken pieces(blisters/bubbles) according to their needs and the immune cleans clean up the rest.

Answer 13

Apoptosis/Tidy cell death

Question 14

Apoptosis happens in every human body and is triggered by

Answer 14

A person’s genetic make up.

Question 15

Example of Apoptosis is

Answer 15

In an embryo development, the foetus’s webbed fingers keeps growing and the webs fall off, then normal fingers are formed.
