Q10

The organs are preserved at ____ Temperature.

A) Low
B) Too high
C) 20C
D) 150C

AI Explanation

Organ preservation for transplantation generally requires reduced metabolic activity, which is achieved by storing organs at low, non-freezing temperatures (typically around 0 to 4 degrees Celsius).

Q11

In ____ of Cryo-preservation, cells are partially dehydrated and survive better.

A) Dry Freezing method
B) Slow freezing method
C) Combined freezing method
D) Rapid freezing method

AI Explanation

During slow freezing, ice forms extracellularly first, causing water to leave the cells via osmosis. This partially dehydrates the cells, preventing intracellular ice crystal formation and enhancing survival.
