Question

Tardigrades, also called water bears, are microscopic segmented animals with eight legs. They are normally about 70 percent body water, but they can survive extreme dehydration (to just a few percent body water) for up to 10 years! After a decade you can add water and the tardigrades will start swimming around. Say you enter a lab. Your new boss gives you five dehydrated tardigrades and asks you to demonstrate that the tardigrades are alive in their dehydrated state. How would you demonstrate this?

Answer 1

I would give them water and when they start swimming it's a proof that they have been alive, after all, how would they start moving if they have been dead
