Answers
i think that it is (d) but is it correct??
The incorrect statements is organism R has poison gland in their skin.
The organisms identified by their characters are
Organism P is camel
Organism Q is a mammal
Organism R is a bird
Organism P is camel as it has leathery lips and big hump on back which is characteristic of camel as it lives in dessert where there is scarcity of water so it conserves water by excreting very little amount of water and its waste is also in form of solid pallets so yes organism P excretes very little water in form of urine hence statement a is true or correct.
Organism Q is mammal as it has thick layer of subcutaneous fat which is bubble or adipose tissue which is directly under skin of mammal and in extreme cold conditions they experience a state of inactivity and metabolic depression known as hibernation or winter sleep and in summer it is called aestivation so statement b is also true.
Organism R is bird as characteristic or identifying feature of all birds is their long colourful beak but except for few birds most of birds do not have poison glands in ts skin hence this is an incorrect statement that birds have poison glands in their skin .
Bird having poison gland is Pitohui. Rest all birds do not have poison glands so incorrect statement is the last statement that is organism R has poison gland in its skin.
