Consider the following statements: Statement-I: Tardigrades are among the most resilient animals which can survive extreme conditions such as exposure to outer space. Statement-II: Tardigrades are able to menifest the process of cryptobiosis and anhydrobiosis very efficiently. Which one of the following is correct in respect of the above statements? |ForumIAS

[A] Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

[B] Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I

[D] Statement-I is incorrect but Statement-II is correct

Answer: A

Notes:

Explanation: Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

Scientific significance of Tardigrades

Resilient: They are among the most resilient animals which can survive extreme conditions such as exposure to outer space.
Cryptobiosis: They owe their incredible resilience to cryptobiosis.
- It is a state in which organisms bring their metabolism to a near-complete standstill in the face of adverse environmental conditions.
Anhydrobiosis: Tardigrades can reduce their metabolism to less than 0.01% of normal, and drop their water levels by more than 95%, a state called anhydrobiosis.
Tun state: Both anhydrobiosis and cryptobiosis result in the emergence of a durable shrunken state, called tun, in which tardigrades are able to withstand extreme conditions.
