  1. Nitro
  2. Penicillin
  3. ampicillin
  4. None of the above
Graduate Cell Structure and Function
The three main parts of cell theory include everything is made of cells, cells are the basic units of life, all cells are produced from ?
  1. the scientific process
  2. animal reproduction
  3. plant photosynthesis
  4. other cells
Graduate Biochemical Pathways
Which polysaccharide consists of individual long, twisted, unbranched chains of glucose?
  1. Starch
  2. Cellulose
  3. Glycogen
  4. This does not describe a polysaccharide.
Graduate Microbiology
Which property or properties of life does a virus possess?
  1. Has order
  2. Has cells
  3. Can reproduce on its own
  4. All of the above
Graduate Botany
Why do some leaves change color (red, yellow, orange, etc.) in the fall?
  1. The chlorophyll molecule is modified to absorb different wavelengths of light.
  2. The chlorophyll molecule breaks down and other pigments now become visible.
  3. Because the leaves are dead.
  4. Cold weather denatures the chlorophyll molecule and it begins to reflect different colors.
Graduate Nervous and Endocrine Systems
Why can the gene that produces insulin in a human be inserted into bacteria and produce the same human insulin?
  1. Because humans evolved from bacteria, the gene for insulin is already present in bacteria.
  2. The insulin gene originated in bacteria and was transferred to humans through an infection.
  3. Humans and bacteria have the same proteins.
  4. Bacterial DNA is made up of the same chemical building blocks as human DNA.
Graduate Biology
What happens to the ATP molecule after it has been used to do work?
  1. It breaks down into carbon dioxide and water.
  2. It is split into two molecules of pyruvic acid.
  3. It loses a phosphate group and is converted to ADP.
  4. It is completely destroyed.
Graduate Biochemical Pathways
In a recent newspaper article promoting the eating of seaweed and seaweed products, the argument was made that doing so was a more efficient use of energy than eating animals. Why would eating seaweed be more energy efficient than eating an animal?
  1. The energy found in animal matter represents a fraction of the energy found in the plant matter eaten by the animal. It would be better to just eat the plant and skip a step.
  2. The conversion of plant matter to animal matter produces less waste than converting animal material to animal material.
  3. Plant matter contains more energy per unit volume than does animal matter.
  4. Plant matter contains more energy per unit weight than does animal matter.
Graduate Biochemical Pathways
The reaction that results in the lengthening of a polymer chain by adding an additional monomer is called a                               .
  1. hydrolysis reaction
  2. hydrogen bond
  3. dehydration synthesis reaction
  4. Van Der Waals forces

  2. C, T, G, A
  3. A,T, P
  4. C, H, O, N
Graduate Macromolecules
What might lead to a protein that does not function properly?
  1. Incorrect folding of the amino acid chain
  2. The active site becoming blocked
  3. The active site becoming distorted
  4. All of these
Graduate Anatomy and Physiology
Anatomy is concerned with
  1. functions
  2. locating problems
  3. naming structures
  4. finding cures
Graduate Nervous and Endocrine Systems

  1. Resonance amplification
  2. Directionality cues for sound source location
  3. Interface impedence
  4. A change of mechanical energy into chemical energy
  5. All of the above
  6. A and B
  7. None of the above
Graduate Biochemical Pathways
All living things require substantial quantities of carbon. Where do plants get the carbon they need to survive?
  1. From decaying organic matter
  2. From the air
  3. From the soil (but not water)
  4. From the water in the soil
