Question 1
In controlled experiments:
A. One variable is manipulated while others are held constant
B. All variables are held constant
C. All variables are dependent on each other
D. All variables are independent of each other
Correct Answer: A. One variable is manipulated while
others are held constant
,Rationale:
A controlled experiment manipulates an independent
variable while keeping other relevant variables controlled or
constant. This allows the researcher to determine whether
changes in the independent variable produce changes in the
dependent variable. Holding every variable constant would
prevent meaningful experimentation.
Question 2
A placebo:
A. Is an urban legend
B. Can produce a perceived or measurable treatment response
despite containing no active therapeutic ingredient
C. Demonstrates that most scientific studies cannot be
replicated
D. Does not exist
Correct Answer: B. Can produce a perceived or
measurable treatment response despite containing no
active therapeutic ingredient
,Rationale:
A placebo is an inactive treatment designed to resemble the
experimental treatment. Participants may experience
improvement because of expectations, conditioning, or other
psychological and physiological factors. This is called the
placebo effect. Placebos are commonly used in controlled
clinical research to help determine whether an active
treatment has an effect beyond expectations.
Question 3
A hypothesis that is created uses which type of reasoning?
A. Deductive reasoning
B. Inductive reasoning
C. Hypothesis reasoning
D. Creative reasoning
Correct Answer: B. Inductive reasoning
Rationale:
Inductive reasoning moves from specific observations to a
broader generalization or tentative explanation. Scientists
often observe patterns and then develop a hypothesis that can
, be tested experimentally. Deductive reasoning instead begins
with a general principle and applies it to a specific situation.
Question 4
Glucose (C₆H₁₂O₆) is an example of a(n):
A. Monosaccharide
B. Disaccharide
C. Ion
D. Polysaccharide
Correct Answer: A. Monosaccharide
Rationale:
Glucose is a monosaccharide, meaning it is a single sugar
molecule. It is an important cellular energy source and can be
metabolized through cellular respiration to produce ATP.
Other monosaccharides include fructose and galactose.
