• Making an observation

• Forming a hypothesis

• Drawing a conclusion

Which of the following is a characteristic of a scientific theory?

• It is a hypothesis that has been proven false

• It is a random guess about natural phenomena

• It is an accepted explanation for how the world works

• It is a law that has been disproven

What is the purpose of using a control group in an experiment?

• To ensure the experimental variable is effective

• To provide a baseline for comparison

• To manipulate the responding variable

• To increase the complexity of the experiment

What is the role of a responding variable in an experiment?

• It is the factor being deliberately changed

• It is the variable that remains constant

• It is the placebo used in the control group

• It is the result of the change to the experimental variable

Which principle is associated with the scientific law of biogenesis?

• Life can arise from nonliving matter

• Living things can only come from other living things

• Life is a result of spontaneous generation

• Life is created through divine intervention

What is the purpose of the scientific method?

• To eliminate the need for observations

• To disprove existing scientific theories

• To collect data and confirm or discard a hypothesis

• To create new scientific laws

What is the purpose of using model systems in scientific experiments?

• To manipulate the responding variable

• To eliminate the need for a control group

• To provide ethical considerations and simplify complex systems

• To increase the complexity of the experiment

What is the role of a hypothesis in the scientific method?

• It is a law that has been disproven

• It is a proposed solution to a scientific problem

• It is an accepted explanation for how the world works

• It is a random guess about natural phenomena

What is the purpose of conducting controlled experiments?

• To manipulate all variables

• To control all factors except the one being tested

• To eliminate the need for a control group

• To increase the complexity of the experiment

What is the purpose of using double-blind studies?

• To manipulate experimental variables

• To ensure unbiased results by keeping the technician unaware of group assignments

• To eliminate the need for a control group

• To increase the complexity of the experiment
