BIOLOGY EOC REVIEW QUESTIONS
#1 WITH COMPLETE SOLUTIONS
A human gene is inserted into a bacterial plasmid. - ANSWER-Which is a step in the
process of producing transgenic bacteria?
a gamete with an extra chromosome forming - ANSWER-Which would most likely
produce a mutation that is passed on to offspring?
Individuals with favorable variations survive and reproduce. - ANSWER-A large
population of cockroaches was sprayed with an insecticide. A few of the
cockroaches survived and produced a population of cockroaches that was resistant
to this spray. What can best be inferred from this example?
fat - ANSWER-Which type of molecule do whales use for energy storage and
insulation?
enzymes - ANSWER-Which most directly controls the rate at which food is broken
down to release energy?
active transport - ANSWER-If energy is needed to move materials into or out of a
cell, what is most likely occurring?
Both contain ribosomes - ANSWER-How are prokaryotic and eukaryotic cells
similar?
by arranging certain nitrogen bases of the cell in a particular order - ANSWER-How
does DNA code for proteins in a cell?
two cells with genetic material identical to the parent cell - ANSWER-What is the
result when a single cell reproduces by mitosis?
movement - ANSWER-These diagrams represent a Euglena and a Paramecium.
What function does the cilia and flagella have in common?
innate behavior - ANSWER-At night, moths travel toward light. Which type of
behavior does this describe?
observing the behaviors of different types of organisms several times during the year
- ANSWER-A field ecologist wants to determine the interactions of various
populations of organisms living in a large grassland field. Which method is best for
conducting
this study?
acid rain - ANSWER-Which environmental factor would cause the greatest decrease
in the number of species of plants and animals living in some of the lakes in the
United States?
, CO2 levels in the atmosphere could increase and contribute to global warming
problems. - ANSWER-If worldwide deforestation is not regulated, what could most
likely result?
It would change the sequence of DNA nucleotides in affected cells - ANSWER-How
would overexposure to X-rays affect most animal cells?
Asexual reproduction produces offspring identical to the parents, but sexual
reproduction produces offspring with traits from both parents. - ANSWER-How are
sexual reproduction and asexual reproduction different?
to treat certain types of diseases - ANSWER-Which is one reason scientists produce
transgenic organisms?
The rate of selection is increased because the pesticides do not kill the insects that
are naturally resistant to it. - ANSWER-The use of pesticides on crops has been a
common farming practice for decades. What has been the greatest effect of natural
selection through the use of pesticides on certain insect populations?
The full classification of organisms will include more categories of organisms than
their scientific names. - ANSWER-What is the difference between the full
classification of organisms and their scientific names?
proteins - ANSWER-What type of organic molecules are enzymes?
nucleotides that store information - ANSWER-What are the subunits of DNA and
their function?
Aerobic respiration results in more energy. - ANSWER-How does the amount of
energy resulting from fermentation compare with that of aerobic respiration?
Chloroplast - ANSWER-This diagram shows a plant cell. Which structure is found in
a plant cell but is absent in an animal cell?
Different genes are activated in their cells. - ANSWER-Which best explains why
muscle cells are different from blood cells?
They will shrink because water will move out of them. - ANSWER-A freshwater plant
is placed in a container of saltwater. What will most likely happen to the cells of the
plant?
interphase - ANSWER-During which phase of the cell cycle is the cell growing and
preparing for cellular division?
to attract female birds - ANSWER-The males of a bird species do a "dance" and
"sing a song" each spring. What is the main purpose of these behaviors?
mutualism - ANSWER-The yucca plant releases a strong scent at night when the
yucca moth is active. The yucca moth, attracted by the scent, gathers pollen from the
yucca flower. The yucca moth then deposits her eggs and the pollen on another
