How does a scientific theory differ from a scientific law?
A law is a theory that has been proven true beyond all doubt and can no longer be updated.
A theory is an untested guess, whereas a law is an established fact.
A law describes what happens under specific conditions, while a theory explains why it happens.
Theories apply only to biology, while laws apply only to physics and chemistry.
Plants are an example of autotrophs because_____
they have green leaves
they make their own food
they cannot travel
they are made of wood
Halophiles are an ancient species of single- celled organisms that live _____
in extremely hot places
in extremely cold places
in extremely salty places
in places without oxygen
Which of the following would a geologist be least likely to study?
earthquakes
food chains
strata
landforms
Which of the following best describes the principle of falsifiability in scientific inquiry?
A hypothesis must be proven true by minimum of 3 independent studies.
A scientific statement must be capable of being proven wrong through observation and experimentation.
Scientific facts never change once they are accepted by the scientific community.
Scientific claims can only be tested using computer simulations rather than direct observations.
Which statement accurately reflects the tentative nature of scientific knowledge?
Scientific knowledge is unreliable because scientists constantly change their minds.
Scientific explanations are open to revision or replacement when new evidence or better interpretations emerge.
Established scientific facts are temporary guesses with little empirical support.
Science can answer all questions about human values, morality, and aesthetics.
Which of the following questions lies outside the scope of scientific investigation?
What is the chemical composition of atmosphere samples on Mars?
Does a specific gene increase susceptibility to cardiovascular disease?
Is a painting by Picasso intrinsically more beautiful than one by Van Gogh?
How do rising ocean temperatures affect coral reef ecosystems?
Which of the following best defines a scientific hypothesis?
A testable explanation proposed for an observed event.
A proven fact that has been tested across many disciplines over several decades.
A casual guess that cannot be evaluated through experimental measurement.
A summary statement that describes a mathematical relationship in nature.
In a controlled experiment investigating the effect of fertilizer amount on tomato plant growth, what is the independent variable?
The total height of the tomato plants measured after four weeks.
The amount of sunlight and water given to each plant.
The type of soil used in the plant pots.
The specific amount of fertilizer added to each plant.
Why is a control group essential in a scientific experiment?
It ensures that the experiment produces the result the scientist expects.
It serves as a baseline for comparison to isolate the effect of the independent variable.
It increases the speed at which data can be collected.
It guarantees that no unexpected errors occur during the testing procedure.
What step should a scientist take if experimental results do not support their original hypothesis?
Change the collected data points so that they align with the hypothesis.
Discard the study and pretend the experiment was never performed.
Analyze the results, revise or refine the hypothesis, and design a new test.
Declare the hypothesis a scientific law despite the contradictory findings.
Which fundamental property distinguishes living organisms from non-living matter?
The ability to move location independently
Maintenance of a stable internal environment through homeostasis
The presence of complex mineral structures
Direct absorption of solar energy for heat
Which subdiscipline of biology specifically focuses on the study of how traits are passed from parents to offspring?
Ecology
Genetics
Physiology
Cytoplogy
