While researching the topic of extremophiles, a student has taken the following notes:
- Tardigrades, also known as water bears, are microscopic animals.
- They are famous for their ability to survive extreme conditions, including the vacuum of space, high radiation, and extreme temperatures.
- This survival is possible through a process called cryptobiosis.
- In cryptobiosis, a tardigrade suspends its metabolic activity almost completely.
- It curls into a dehydrated ball called a tun, waiting for conditions to improve.
The student wants to write a sentence that emphasizes the unique mechanism behind the tardigrade's resilience. Which choice most effectively uses relevant information from the notes to accomplish this goal?
-
A
Tardigrades, which are microscopic animals also called water bears, can survive in the vacuum of space and other harsh environments.
-
B
Through a process known as cryptobiosis, tardigrades can survive extreme conditions by suspending their metabolic activity almost completely.
-
C
When a tardigrade enters a state of cryptobiosis, it curls up into a dehydrated ball called a tun.
-
D
The resilience of tardigrades, which allows them to endure high radiation and extreme temperatures, is a topic of great scientific interest.
