Question 2

Excretion

Answer 2

Removal from organisms of toxic materials, waste products of metabolism (chemical reactions in cells including respiration) and substances in excess requirements

Question 3

Respiration

Answer 3

Chemical reactions that break down nutrient molecules in living cells to release energy

Question 4

Sensitivity

Answer 4

The ability to detect or sense changes in the environment (stimuli - something which rouses activity (specific) in an organ or tissue) and to make responses

Question 5
