background image   1. The use of energy and matter by living organisms_______.  a. Involves chemical cycling from light energy from the sun for the production of  chemical energy in food to the decomposition and the returning of chemicals to 
the cycle 
b. Involves chemical cycling from chemical energy in food to light energy from the  sun to heat lost from the ecosystem  c. Is a noncyclic process 
d. Never leads to the loss of heat from the ecosystem 
2. The units of inheritance are called______.  a. Genes 
b. Chromosomes 
c. Proteins 
d. Membrances 
e. The double helix 
3. Some properties and processes that are associated with life include all of the following  except_____.  a. Reductionism 
b. Growth and development 
c. Reproduction 
d. Order 
e. Energy 
4. With evolution as the core theme of biology, we can explain traits shared by organisms  as evidence of _______ and traits that differ among organisms as evidence of ______.  a. Descent from a common ancestor; chance 
b. Coincidence; adaptation 
c. Descent from a common ancestor; adaptation through natural selection 
d. Systems biology; reductionism 
e. Qualitative data; quantitative data 
5. The avian flu virus H5N1 is considered a greater long-term threat than the swine flu virus  H1N1 because_______.  a. It is more readily transmitted between human hosts 
b. H5N1 is a DNA virus and the similarity of genome chemistry can promote greater 
virulence and therefore likelihood of death in humans  c. H5N1 has a greater tendency to become a prophage 
d. More people eat chicken meat than pork 
e. It has a significantly higher mortality rate 
6. How are retroviruses different from other types if viruses?  a. Retroviruses use the enzyme reverse transcriptase to transcribe a copy of DNA  from their own RNA  b. Retrovirus DNA is incorporated into the host cell’s DNA in order to be translated 
c. Retrovirus DNA is used directly by the infected cell to transcribe and translate 
viral proteins 
background image d. Retrovirus DNA is incorporated into the host cell’s DNA in order to be translated 
e. Retrovirus RNA is used directly by the infected cell to produce viral proteins 
7. A widespread outbreak of a viral disease is called a(n) ______, and a global outbreak is  called a(n) ________.  a. Retrovirus; phage 
b. Viroid; prion 
c. Epidemic; pandemic 
d. Vaccine; emerging virus 
e. Pandemic; epidemic 
8. The original atmosphere of Earth had little oxygen. What was the likely first source of  oxygen that led to an oxygen atmosphere>  a. Flowering plants 
b. Cyanobacteria 
c. Eukaryotic algae 
d. Cone-bearing plants 
e. Mycorrhizae 
9. You are watching a movie in which one of the characters excitedly claims to have found  human remains in Asia dated at 10 million years old. The date was obtained by 
carbon-14 dating. What is you reaction? 
a. This would be surprising finding because so far there is no evidence that humans  existed that long ago.  b. This can’t possibly be true because carbon-14 dating can only be used back to  about 75,000 years.  c. This can’t possibly be true because the earliest humans came from Africa, not  Asia  d. This can’t possibly be true because humans weren’t around 10 million years ago. 
e. This is a perfectly reasonable finding 
10. Which of the following is a structure that bacteria, archaea, and eukaryotes have?  a. Plasma membrane 
b. Circular chromosome 
c. Membrane-enclosed organelles 
d. Peptidoglycan cell wall 
e. Nuclear envelope 
11. Bacteria that use light for their energy source and CO 2  for their carbon source are  called______.  a. Photoautotrophs 
b. Chemoautottrophs 
c. Photochemoautotrophs 
d. Photoheterotrophs 
e. Chemoheterotrophs
