THE NEXT QUESTION IS BASED ON THE FOLLOWING INFORMATION
Many years ago, people believed that flies were created from spoiled food because spoiled food
that was left out in the open often contained fly larvae. So a scientist placed fresh food in a
,sealed container for an extended period of time. The food spoiled, but no fly larvae were found
in the food that was sealed.
Based on this evidence, what is the most likely reason that spoiled food left out in the one often
contained fly larvae?
A. The spoiled food evolved into fly larvae.
B. Since the food was left out in the open, flies would lay eggs in the food.
C. Fly larvae were spontaneously generated by the spoiled food.
D. People only imagined they saw fly larvae in the spoiled food.
B. Based on the evidence, the most likely explanation for fly larvae in the spoiled food is that
flies laid their eggs in the food.

the 19th century was about 40 years. What is a possible explanation for the longer life
expectancy in the present age?

B. Knowledge abut how basic cleanliness can help avoid lines has enable people to live longer.
C. The creation of various vaccines has enable people to live longer.
D. All of the statements above offer reasonable explanations for longer life expectancy.
D. Longer life expectancy could be explained by any or all of the alternatives presented.
- Advances in medical technology, basic cleanliness, and vaccines could all help people live
longer in the 21st century.

diagnosis to help the patient.
D. the patient has excellent insurance that will pay for several test, and the doctor would like to
run as many tests as possible.

Which of the following is a protein that interferes with virus production?
A. lysozyme
B. prion
C. interferon
D. keratin
C. Interferons are members of a larger class of proteins called cytokines.
- Cytokines are specialized proteins that carry signals between cells.
- Interferons are proteins that are produced by cels infected by pathogens such as viruses.
Which of the following does not contain blood vessels?
A. hyperdermis
B. hypodermis
C. dermis
D. epidermis
D. Epidermis
, Humans have three layers of skin called the epidermis, the dermis, and subcutaneous fat.

the bottom layer.
- The epidermis does not contain blood vessels.
The first four steps on the scientific method are as follows:
I. Identify the problem.
II. Ask questions.
III. Develop a hypothesis.
Iv. Collect data and experiment on that data.
Which of the following is the fifth step in the scientific method?
A. Observe the data.
B. Analyze the results.
C. Measure the data.
D. Develop a conclusion.
B. Analyze the results.
- There are six steps in the scientific process. The results of step four must be analyzed before
reaching the final step. "Develop a conclusion."
Which of the following is FALSE regarding the use of qualitative and quantitative data in
scientific research?
A. Quantitative data is collected through numerical measurements.
B. Quantitative data is more accurate than qualitative data.
C. Qualitative data is focused on perspectives and behavior.
D. Qualitative data is collected through observation and interviews.
