Physiological Action - (i) Nitrogen is non-poisonous. But animals placed in an atmosphere of nitrogen die due to asphyxiation (lack of oxygen). (ii) Nitrogen dilutes the oxygen of the air and helps in regulating the rate of respiration and combustion. Breathing in pure oxygen en..

>Nerve Net of HydraThe nervous system is made up of units called the neurons which relay information by generating electric potential. The endocrine system, on the other hand, is made up of glands that secrete chemicals called the hormones. They are secreted into blood that carries them t..

Summary - Excretion is the elimination of waste products from the body. The non - volatile products are mainly excreted in the urine. The urinary system consists of those organs which form, store and void urine. The nitrogenous wastes are mainly produced by catabolism of proteins. Animals..

The impulse is received by the dendrites and passed through the cell body to the axon. An impulse is an electrical disturbance. All along the nerve fibre, the cytoplasm is more electronegative than the outside and is thus having a potential. This is due to the differential distribution o..
