Explanation
(a)(i) Respiration is a metabolic process which takes place in living cells by which organic nutrients are broken down to release energy or ATP for life activities.
(ii) Two types of respiration are

(ii) The following are the diseases of the lungs:
Lung cancer; tuberculosis, pneumonia, bronchitis, asthma, common cold, .whooping cough and SARS/Influenza.
(c) The structures used for gaseous exchange in these organisms are:
Amoeba—Cell membrane/body surface
