Answer:
Compressibility is reducing the volume by increasing the pressure of a substance like liquid or gas. It is a physical characteristic of a substance especially gases.
Everyday life examples:
(1) LPG - These gas cylinders have compressed natural gas to liquid gas to store and use as fuels.
(2) Tubes of bicycles are filled by the pumps that compress the air.
(3) Carbonated soda filled with the help of compressing the carbon dioxide into the bottle.
4) oxygen bottles in medical institutes for helping the patient to breathe.

The correct answer is: Formation of the MAC in invading cells, killing them
The complement pathway or system is a part of the innate immune system that helps antibodies and phagocytic cells to clear microbes and damaged cells from an organism. Its role is to enhance and promote inflammation, and to attack pathogen's cell membrane. The complement system consists of a number of small proteins and as a result of their activation these are the mechanisms of action:
• stimulation of phagocytes
• inflammation to attract more phagocytes,
• activation of the cell-killing membrane attack complex (MAC).
