"Cryptobiosis" is a state of almost total water loss found in some roundworms,rotifers,and tardigrades and was previously considered a near cessation of metabolism.Recently,a British Museum botanist accidentally spilled fluid on a 120+year-old herbarium mount of a lichen.Fearing damage to the specimen,he immediately inspected it under the microscope and found tardigrades "waking up." This observation
A)supports the claim that the tardigrades were dead but began respiring again at a very slow rate after the fluid was added. B)makes it possible that we can bring most dead animals back to life. C)contradicts both the cell theory and evolutionary theory. D)indicates metabolism did not stop,and that organization and water made it sufficient to maintain the possibility for "life."
