Question

Which of the following statements are incorrect among the options given below?

• A. Plants do not have mechanism to maintain internal temperature
• B. Polar bears going into hibernation during winter is an example of escape of area
• C. Desert lizard has physiological ability to regulate
• D. Success of mammals is largely due to their ability to maintain a constant body temperature

Answer 1

Answer: (B), (C)

The correct options are
B Polar bears going into hibernation during winter is an example of escape of area
C Desert lizard has physiological ability to regulate

• For the regulation of body temperature, there is an internal mechanism called homeostasis, This regulates the internal body temperature in mammals but is absent in plants.
• During winters the polar bears do not undergo hibernation, instead, they remain active. Their body temperature is maintained by the fur-coated on their body which protects them from extreme cold and snow.
• Desert lizards are conformers (They cannot regulate their own body temperature and requires external factors like the sun).
• So, the correct option is ' Polar bears going into hibernation during winter is an example of an escape of area and Desert lizard has a physiological ability to regulate'.
