Answer 2

(1) Plants get rid of carbon dioxide and oxygen through diffusion. Old branches and leaves shed off when they become useless. Plants have a mechanism to release some waste product through roots also. Some waste products are deposited near bark mark as raisins or gums.

(2) The Kidney is equipped with a mechanism to re-absorb water from the filtrate. This depends on how much water is left in the body and in the filtrate. The comparative concentration of water gives a signal to the brain which then takes the required corrective action of either absorbing water or releasing more water. Thus, the amount of urine formation is regulated by the Kidneys.
