Origins: Chapter 4 Test

Louis Pasteur helped to disprove spontaneous generation by:

• Showing that maggots could not arise spontaneously from rotten meat.

• Demonstrating that microorganisms could not arise spontaneously

• Testing Oparin’s theory

• None of these

Francisco Redi helped to disprove spontaneous generation by:

• Boiling beef broth in a jar

• Performing an experiment on amino acids

• Showing that maggots could not arise spontaneously from rotten meat

• Helping Stanley Miller test Oparin’s theory

In the experiment on rotten meat, maggots formed:

• In all the jars

• In none of the jars

• In the covered jars only

• In the uncovered jars only

In the experiment on beef broth, microorganisms formed:

• Only in the flasks contaminated by dust

• In all the flasks

• In none of the flasks

• Only in the flasks uncontaminated by dust

“Living things can come only from other living things” is:

• The principle of biogenesis

• The second law of thermodynamics

• A description of spontaneous generation

• None of these

Oparin's theory:

• Attempted to explain the principle of biogenesis

• Attempted to explain Stanley Miller's experiment

• Took into account all the chemical processes of life

• Attempted to explain how spontaneous generation of the first cell could take place

Stanley Miller attempted to test Oparin's theory, but the experimental apparatus contained one thing not present in nature. This was:

• A. A condenser

• B. An energy source

• C. A trap

• D. A heat source

The ocean could not protect amino acids because

• The sun's ultraviolet rays could still destroy them

• The water would dissolve them

• Neither answer is correct

• Both are correct

In order to form proteins from amino acids are absolutely necessary.

• Lactic acids

• Enzymes
• UV rays

• None of these

Enzymes are:

• Proteins

• Sugars

• Inorganic molecules

• Proteinoids
