FCTE Biology Questions and Answers
Biology students performed an experiment to determine the effect of temperature on heart rate in
the crustacean Daphnia. Each group of students exposed Daphnia to varying temperatures from 0 °C
to 30 °C and measured the number of heartbeats per minute for three Daphnia after 1 minute of
exposure to each temperature. An average was taken for the three Daphnia at each temperature.
Identify the independent variable for this experiment.
heart rate
temperature
number of crustaceans
length of exposure Correct Answer Temperature
To be effective, a simple experiment must
occur in a research laboratory.
stand alone without replication.
manipulate one variable at a time.
validate the hypothesis being tested. Correct Answer Manipulate one variable at a time
Which of the following types of data is considered quantitative?
plant height
flower color
bird species
, FCTE Biology Questions and Answers
fish gender Correct Answer Plant height
Farmers currently use genetically enhanced varieties of seed because these varieties
provide greater resistance to disease and pests.
yield crops that require less labor to harvest.
reduce soil loss on erosion-prone land.
increase biodiversity in native populations. Correct Answer Provides greater resistance to disease
and pests.
A student finds a bat sleeping on the ground outside the school and asks to bring it inside to show
the class. The teacher should deny this request and caution everyone to stay away from the bat
because bats are Correct Answer Often carries and likely to bite if they are infected with the disease.
Which of the following participants in chemical reactions are most likely to be regenerated and not
appear in the net reactions? Correct Answer catalysts
Reactants of a chemical reaction Correct Answer
Products of a chemical reaction Correct Answer
Intermediates of a chemical reaction Correct Answer
NAD+ functions in the citric acid cycle as a(an) Correct Answer hydrogen acceptor
In human blood types, a person with both the A allele and the B allele will have type AB blood that
has antibodies reflecting the presence of both alleles; therefore, the A and B alleles show Correct
Answer codominance
hydrogen acceptors are Correct Answer
