If both the assertion and reason are false
Answer» Correct Answer - B (b) Walter Cannon (1932) was introduced the term hormeostasis (homeios = same, stasis= standing ). Homeostasis maintains the stability of the cell envirnoment and this way provides the organism with a degree of independence of the environment , in order to achieve stability .Mammals have two kidneys which perfrom excretory function and maintain urea level in blood .
