Assertion : The aquatic organisms in which the osmotic concentration and temperature of body change according to the ambient conditions of water are referred to as conformers.
Reason : Aquatic organisms are able to maintain homeostsis through thrmoregulation and osmoregulation by physiological or behavioural means.

Given is a graph showing organismic response of 3 types , A,B,C For an aquatic organism whose osmotic concentration of the body fluid changes with that of the ambient water osmotic concentration, which graph best depicts this response.

Assertion: Many adaptations have evolved ever a long evolutionary time and are genetically fixed. Reason: Some organisms coping with extremes in the environment able to respond through certain physiological and behavioural adjustments.

The organism in which body temperature changes with the ambient temperature and in aquatic animals, the osmotic concentration of the body fluid change with that of the ambient water osmotic concentration. These animals and plants are simply

A ……..regulators are able to maintain homeostasis by means which enesures constant body temperature constant osmotic concentration, etc. All ……B……..and …………C…………and a very few lower vertabrate and invertebrate species are indeed capable of such regulation (thermoregulation and osmoregulation). Evolutionary biologists believe that the success of mammals is largely due to their ability tomaintain a constant body.........D.........and thrive wheather they live in Antarctica or in the sahara desert Choose the correct option for A,B,C and D .

Choose the incorrect statement(s) for conformers. A. Aquatic animals can change osmotic concentration of body fluids with that of the ambient water osmotic concentration. B. Body temperature doesnot change with small fluctuation in environmental temperature. C. Cannot maintain a constant internal environment
