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?
