b. Increasing the pressure by two-fold
c. Decreasing the activation energy by three-fold
d. Decreasing the concentration of reactants by two-fold
3) Group one in the periodic table has valence electrons and is reactive than Group two.
a. Zero; more
b. Zero;
less c.
One; less
d. One; more
4) Enzymes are created from amino acid chains. As such, what might prevent the action of
an enzyme?
a. A pH close to 7
b. A high temperature
c. The lack of hydrogen ions in solution
d. A lack of ATP in the cell
5) If a scientists want to determine the rate at which an enzyme works, what could he or
she measure?
a. The rate at which the enzyme is degraded
, b. The rate at which the product disappears
c. The rate at which the
reactants disappear d. The rate at
which the products appears
6) The rate of a chemical reaction depends on all of the following except
a. Surface area
b. Temperature
c. Presence of
catalysts d. Amount
of mass lost
7) Which of the answer choices provided best defines the following statement?
For a given mass and constant temperature, an inverse relationship exists between the
volume and pressure of a gas?
a. Boyle’s Law
b. Ideal Gas Law
c. Charles’ Law
d. Stefan-Boltzmann Law
8) Prokaryotic and eukaryotic cells are similar in having which of the
following? a. Integral membrane proteins in the plasma
membrane
b. Presence of a nucleus
c. Membrane-bound organelles
d. Protein-studded DNA
9) Blood cells that are responsible for transportation of oxygen are called
a. Leukocytes
b. Thrombocyte
s c. Erythrocytes
d. Plasma cells
10) What is another name for the Adam’s Apple?
a. Vocal box
b. Thyroid cartilage
c. Cricoid cartilage
d. Hyoid bone
11) When exhaling, the diaphragm
, a. Relaxes
b. Contracts
c. Moves down and in
d. Stays in the same position
12)Which of the following correctly lists the cellular hierarchy from the simplest to
most complex structure?
a. Tissue, cell, organ, organ system, organism
b. Organism, organ system, organ, tissue, cell
c. Organ system, organism, organ,
tissue, cell d. Cell, tissue, organ, organ
system, organism
13) If a cell is placed in a hypertonic solution, what will happen to the cell?
a. It does not affect the cell
b. It will swill
c. It will stay the
same d. 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.

a. Cytokinesi
s b.
Interphase
c. Metaphase
d. Mitosis
15) B = alleles for brown eyes; g = alleles for green eyes
B g
B Bg Bg
g Bg gg
What word describes the allele for green eyes?
a. Heterozygous
b. Dominan
t c.
Recessive
d. Homozygous
