Early 19th-century scientists believed that living organisms differed from nonliving things as a result of processing a "life force" that could create organic molecules from inorganic matter. The term given to this belief is
The concept of vitalism is based on a belief in a life force outside the jurisdiction of physical and chemical laws. According to this belief, organic compounds can arise only within living organisms. Which of the following did the most to refute the concept of vitalism?
Miller's experiments with ancient atmospheres.
The experimental approach taken in current biological investigations presumes that
living organisms can be understood in terms of the same physical and chemical laws that can be used to explain all natural phenomena.

A, B, and C are correct
What is the reason why hydrocarbons are not soluble in water?

Arrangement of carbon, hydrogen, and oxygen atoms.
Which of the following is true of geometric isomers?
They have variations in arrangement around a double bond.
Research suggests that side effects from Ritalin, the drug used to treat ADD, may be caused by contamination of enantiomers, or molecules that
