Question

Which features adapt penguins to live in extremely cold conditions?
A.A white colour thick skin and less fat
B.Thin skin, large eyes, white fur
C.White colour, thick skin and lot of fat
D.White body, paws for swimming, gills for respiration

Answer 1

Hint: Adaptation is any morphological, physiological or behavioral attribute of an organism that enables it to survive and reproduce in its habitat.
-Mammals living in the colder climates have shorter ears and limbs to minimize heat loss.
Many mammals have a thick layer of fat called blubber below their skin.
-Penguins live in the Antarctic and Arctic region.

Complete step by step answer:
-Penguins white colour helps them to blend in with the white background.
-They have to keep high body temperature to remain active.
-Thick skin and thick layer of fat called blubber below their skin act as an insulator and prevents loss of body heat to protect it from cold.
-Because of all the adaptations mentioned they adapt to live in extreme climates.
-The penguins huddle together in groups to keep themselves warm
-Penguins are flightless birds, but are excellent swimmers
They have webbed feet and they streamline their body while swimming which makes them good swimmers

So the correct answer is option C. White colour, thick skin and lot of fat

Note:
-Thick skin and a lot of fat under the skin makes the penguin adaptable in the extremely cold environment.
-The wings shaped like flippers also help them fly underwater at speeds up to 15 kmph
Penguins tightly packed feather overlap to provide waterproofing and warmth
