Breathing using lungs

D
Viviparity
Solution
Answer: (D) Viviparity.
Explanation:
Birds and mammals both have the ability to maintain their constant body temperature, this is known as homeostasis.
So, birds and mammals both are warm-blooded in nature.
The endoskeleton of both birds and mammals is made up of bones. So, both have ossified endoskeletons.
Both birds and mammals use lungs as their respiratory organs and hence for breathing.
But, birds are oviparous while mammals are viviparous.
Hence, viviparity is not a common characteristic shared by both birds and mammals.

Muscles connected with working of insect heart are

A
Alary

B
Pericardial

C
