Question

Which of the following animals sleeps most of the time during the winter season?
A.Sloth
B.Dog
C.Lizard
D.Cat

Answer 1

Hint: Their square measures two styles of organisms; regulators and conformers. Regulators square measure those who can maintain their internal temperature to keep with the external atmosphere. Example: dog, cat, sloth etc.

Complete answer:
Conformers square measure the organisms which will not maintain internal temperature to keep with the atmosphere so that they need sleep throughout harsh climates to survive. Example: lizards, polar bears.

Lizard being a vertebrate is that cold-blooded organism. they are typically conformers, that is they'll not maintain their internal temperature to keep with the external atmosphere. So lizards, thus coping up the cruel climate, hibernate throughout winters by going into a dormant section.

Aestivation is that the range of summer sleep, performed by cold-blooded animals. It helps in maintaining the temperature by avoiding the excessive water loss and any internal body broken due to high temperatures. it's performed by bees, snails,

Birds and mammals square measure samples of warm-blooded animals. Dogs and cats square measure homeotherms, which suggests they maintain a fairly constant temperature of 1 hundred and one to 102 degrees
Hot blooded invariably have identical temperature unless the square measures sick.

Hence the correct answer is OPTION(C)

Note: 1.Aestivation is dormancy of an associated animal throughout a hot or dry quantity.
2.Hibernation can be a state of greatly reduced metabolic activity associated with down temperature adopted by certain mammals as associate degree adaptation to adverse winter conditions.
3.Migration is the relatively long-distance movement of individual animals, generally on a seasonal basis.
4.The physical and activity choices of animals designed thus to survive their natural surround square measure are spoken as permutations.
