These are external and internal respiration. The external respiration involves breathing in oxygen into the lungs called inhalation and breathing out of carbon(iv)oxide called exhalation. The inhalation process is as follows. The thoracic cavity increases in volume; diaphragm contracts, the sternum moves forward together with the ribs, there is an increase in the volume of thoracic cavity and air from outside is drawn into the lungs through the nose ----------------------- (5) (ai) (i)Cutting (ii) layering (iii) grafting (iv) marcothing (aii) (i)Pepsin – protein (ii) Renin – milk (aiii) Phytoplanletone ==>mosquito larva ==>tilapia ==> shark (bi) Tabulate Aerobic respiration (i)Oxygen is required (ii)More energy is release (iii)It takes place in the mitochondria (iv)Water is given off as by- product Anaerobic respiration (i)Oxygen is not required (ii)Less energy is released (iii)It takes in cytoplasm (iv)Alcohol is given of as by- product (bii) (i)Carbon dioxide (ii) water vapour (biii) (i)The liver regulates the blood sugar level (ii)It helps in the storage of vitamins (iii)It detoxifies poisonous and toxic materials ====COMPLETED====add us on 2go Sunery6
