Answer 2

Answer:

a) Aerobic respiration is a set of metabolic reactions that take place in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives.

b) Special excretory organs are absent in unicellular organisms like amoeba. 2) Amoeba possesses osmoregulatory organelle called contractile vacuole. 3) It collects water and wastes from the body, swells up, reaches the surface and bursts to release its content to outside.
