1. Which of the following B
resulted from the
invention of the
microscope?
A. the development of the
theory of evolution
B. the development of the
cell theory
C. proof that cells can
form spontaneously
D. proof that all cells have
the same basic structure
2. The potato famine in C
Ireland (1845-1852)
occurred when a fungus
escaped by chance out of
Mexico and into North
America and Europe. The
fungus, which caused
crop-destroying potato
blight, apparently came
from a single clonal
genotype The potato
population was probably
vulnerable to infection by
this fungus because of
which of the following?
A. lack of genetic drift
B. not enough organisms
C. lack of genetic variation
,3. Lipid synthesis is carried A
out in which part of the
cell?
A. smooth endoplasmic
reticulum
B. rough endoplasmic
reticulum
C. ribosomes
D. lysosomes
4. In hamsters, the gene A
for short hair (H) is
dominant to the gene for
long hair (h). Which is the
most likely genotype of
the parents if 4 of their 8
offspring have long hair
A. Hh X hh
B. Hh X Hh
C. HH X hh
D. hh X hh
5. Which of hte following B
is a limiting factor that is
density-independent?
A. an outbreak of disease
B. a forest fire caused by
lightning
C. immigration of new
predators
D. competition for scarce
resources
6. Which of the following C
classifications includes all
three of the others?
A. family
B. genus
C. phylum
D. order
, 7. A certain enzyme D
oxidizes ethanol. If a
genetic defect prevents
the enzyme from being
produced, which outcome
do you predict would
occur?
A. Ethanol would undergo
reduction, which is the
opposite process of
oxidation.
B. The oxidation of ethanol
would proceed only in
certain locations in the
cell.
C. The cell would employ
a different enzyme to
oxidize ethanol.
D. The oxidation of
ethanol in the cell would
happen very slowly or not
at all.
8. Which of the following C
is a key difference
between mitosis and
meiosis?
A. Mitosis allows for
genetic variation, while
meiosis results in
generations of organisms
with stable characteristics
B. Mitosis produces cells
that are almost identical
genetically, while meiosis
produces cells that differ
genetically from each
parent or from each other.
C. Mitosis produces cells
that are almost identical
genetically, while meiosis
produces cells that differ
