Question

Directions: Choose the correct option:

Assertion $\left(A\right):$ Hibernation during winter and aestivation during summer is seen in frogs.

Reason $\left(R\right):$ Frogs are poikilotherms.

• A. Assertion$\left(A\right)$ is false and reason$\left(R\right)$ is true.
• B. Both assertion$\left(A\right)$ and reason$\left(R\right)$ are true, but reason$\left(R\right)$ is not the correct explanation for assertion.
• C. Both assertion$\left(A\right)$ and reason$\left(R\right)$ are true and reason$\left(R\right)$ is the correct explanation for assertion$\left(A\right).$
• D. Assertion$\left(A\right)$ is true and reason$\left(R\right)$ is false.

Answer 1

The correct option is C Both assertion$\left(A\right)$ and reason$\left(R\right)$ are true and reason$\left(R\right)$ is the correct explanation for assertion$\left(A\right).$

Correct option: $\left(a\right)$Both assertion$\left(A\right)$ and reason$\left(R\right)$ are true and reason$\left(R\right)$ is the correct explanation for assertion$\left(A\right).$

$\bullet$ Frogs are not capable of regulating their body's temperature according to the temperature of the surrounding.

$\bullet$ So, they are known as cold-blooded animals or poikilotherms.

$\bullet$ Due to these reasons, frogs become inactive during extreme winter and summer conditions.

$\bullet$ The winter sleep is known as hibernation and the summer sleep is known as aestivation.

$\bullet$ Both help the organisms to lower their metabolism and conserve energy.

$\bullet$ So, the correct answer is $\left(a\right)$
