8) "Self-replicating molecular assemblage" is a classic definition of life. However, clay particles in clay soil contain aluminum and iron compounds that determine the pattern of particles in adjacent layers over time and, therefore, represent a self-replicating molecular assemblage. What can we conclude?

A) Clay soil is living.
B) Clay soil is not living because there was no molecular change involved.
C) Clay soil is not living because no carbon is involved; otherwise, such replication would be living.

A) evolution.
B) metabolism.
C) adaptation.
D) homeostasis.

10) "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 a120+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) is science because it is predictive of what will happen tomorrow morning.
B) is scientifically valid because there is probably a connection between loud noise and absence of tigers.
C) is not valid unless there is the potential for tigers to be here, or a test is run with tigers.
D) cannot be scientifically treated because it involves human behavior.

39) From Missouri to central Ohio to Pennsylvania, many people believe that they have water moccasins ("cottonmouth snakes") in their farm ponds.
