• Always uses electrons from only of the atoms involved
• Uses all the electrons in all atoms involved
• Uses the valence electrons of all the atoms involved
• Which of the following would have the most dramatic effect in changing the reaction
rate?
• Decreasing the temperature by two-fold
• Increasing the pressure by two-fold
• Decreasing the activation energy by three-fold
• Decreasing the concentration of reactants by two-fold
• Group one in the periodic table has valence electrons and is reactive
than Group two.
• Zero; more
• Zero; less
• One; less
• One; more
,• Enzymes are created from amino acid chains. As such, what might prevent the action
of an enzyme?
• A pH close to 7
• A high temperature
• The lack of hydrogen ions in solution
• A lack of ATP in the cell
• If a scientists want to determine the rate at which an enzyme works, what could he or
she measure?
• The rate at which the enzyme is degraded
• The rate at which the product disappears
• The rate at which the reactants disappear
• The rate at which the products appears
• The rate of a chemical reaction depends on all of the following except
• Surface area
• Temperature
• Presence of catalysts
• Amount of mass lost

• Contracts
• Moves down and in
• Stays in the same position
• Which of the following correctly lists the cellular hierarchy from the
simplest to most complex structure?
• Tissue, cell, organ, organ system, organism
• Organism, organ system, organ, tissue, cell
• Organ system, organism, organ, tissue, cell
• Cell, tissue, organ, organ system, organism
• If a cell is placed in a hypertonic solution, what will happen to the cell?
, • It does not affect the cell
• It will swill
• It will stay the same
• It will shrink
Hypertonic solution is a solution with a higher particle concentration and lower water
content outside the cell. Water moves from the cell to the solution, losing water and
shrinking.

g Bg gg
What word describes the allele for green eyes?
• Heterozygous
• Dominant
• Recessive
• Homozygous
• Recessive alleles are represented by lower case letters
