A ______ is a well-tested hypothesis that is well-accepted among the scientific community. -
Answer Theory
True or False: A researcher can use the results of her experiment to prove that her hypothesis is
correct. - Answer False
The variable that we manipulate in an experiment is the ________. - Answer independent
variable
The variable that is measured in an experiment is the _________. - Answer dependent
variable
is the standard of comparison used in an experiment. - Answer Control
Name two characteristics of a reliable experiment. - Answer Increase the number of samples
(sample size).Repeat the experiment (all steps of the scientific method) at least 3 times.
Underline the dependent variable:A student observed dead fish floating on the Tennessee River.
He also noticed a coal plant on the river. He noticed that there were more dead fish closer to
where the coal plant was. He thought that waste from the coal plant was causing a change in
the pH of the water, and killing the fish in the river. He set up an experiment to test his
hypothesis, since waste from the coal plant affects pH of the water.The student obtained
samples from different points on the river. 0 m, 100 m, 200 m,300 m, 400 m, 500 m, 600 m, 700
m, 800 m, 900 m, and 1000 m away from the coal plant, and tested the pH of each sample. -
Answer tested the pH of each sample.
Epidemiology is defined as the study of ________.
a. bacteria and viruses
b. vectors of disease transmission
c. factors affecting the health and illness of populations - Answer c. factors affecting the
health and illness of populations

bacterium, and the ____ that spread the disease from mice to humans were fleas.
a. host; pathogen

Which of the following is a characteristic of a virus?
a. It is a living thing
b. It has a true nucleus
c. It must have a host to replicate itself
d. Viral infections can be cured
e. All of the above are characteristics of a virus - Answer c. It must have a host to replicate
itself
How do certain bacteria become resistant to antibiotics? - Answer Antibiotic resistance is
what happens when a bacterium adapts to the presence of a drug to the point that an antibiotic
is no longer affective.People contribute to this problem by over-using antibiotics for themselves,
not taking medication as directed, doctors over-prescribing medications, and/or by feeding
livestock with feed containing high amounts of antibiotics.
Which of the following is true regarding vaccinations?
a. Vaccines typically contain dead or weakened forms of a pathogen.
b. Vaccines improve immunity against future infection.
c. Ceasing vaccinating could allow diseases that are no longer an issue, such as polio and
smallpox, to come back with epidemic force.
d. All of the above are true in regards to vaccinations. - Answer d. All of the above are true in
regards to vaccinations.
True or False: Condoms provide ample protection against genital HPV. - Answer False
Which of the following diseases is NOT caused by a bacterium?
a. Chlamydia
b. Tetanus
, c. The bubonic plague
d. All of the above are caused by bacteria - Answer d. All of the above are caused by bacteria

classmates?
a. The large 50 mL tube of fluid
b. The pipet (disposable dropper)

for cell respiration, form certain structures ("hardware") of cells, store energy, or provide
building materials for other biomolecules
