osmoconforms; "Animal cells require more critical balance of water and solutes in body as they cannot survive a net water gain or lose.water continuously leave and enter the cells; however, the quantity of water and the solutes is kept in balance . there are two approaches in maintaining this balance. I) osmoconforms Animal body fluid are kept isotonic to the external environment even for marine saltwater environment. these animals thus do not require actively to adjust their internal osmotic state , so are known as osmoconforms .
in the animals whose body fluid concentration differs noticeably with outside environment actively regulate to discharge excess water and excrete salt in hypotonic and hyperlon ic condition respectively , therefore are called as osmoregulators". Define variable and set point: ? "Variable; the internal factors which are influenced by external environment are called variable. e.g body temperature, water and solutes concentration etc. set point; set point is the ideal or normal values of variable that is previously set or stored in memory. " Define homeostasis: ? "Homeostasis; Homeostasis is the tendenev of an organism or cells to regulate its internal environmental conditions , such as chemical composition of its body fluid , so as the maintain health and function ing regardless of outside condition."
