2:false

3:true

Answer:

Ans. 1

False.

Some cells use the process of metabolism which is fragmentation to produce energy. So, the statement is not true.

Ans. 2

False

Aerobic respiration breaks down glucose and combines the broken down substances with O2, making water and carbon dioxide.

Ans. 3

True.

The role of alveoli in respiration is gas change, as the wall of alveoli is so thin so it allows the gas to pass through it.

And this process is called diffusion.
