Q. Find out the correct ones I. Mammals of colder climate generally have shorter ears and limbs to minimize heat loss II. All organisms have behavioural adaptations that allow them to respond quickly to a stressful situation III. Some organisms possess behavioural adaptations which allow them migrating temporarily to a less stressful situation IV. Invertebrates and fishes live at great depths in the ocean have biochemical adaptation to cope with high pressure
A) I and II
B) II and III
C) I, III and IV
D) I, II and IV
Explanation
I, III and IV. Some organisms show behavioural adaptation to cope with variation in environment. Desert lizards lack the physiological ability to deal with high temperature. They keep their body temperature fairly constant by behavioural means. They enjoy in sun and absorb heat when their body temperature is low. When their body temperature starts increasing it moves into shades
