Michael's grandmother is taking part in an experiment to determine how well a new headache medication works. In this experiment, the people in Group A are taking the new medication. The people in Group B, including Michael's grandmother, are taking a pill that does not contain the new medication. In this experiment, what is Group B?
Group B is the control group.
Group B is the experimental group.
Group B is the independent variable.
Group B is the dependent variable.
Which field of biology could involve manipulating genes, breeding new plants and animals, or incorporating living systems into an invented device or process?

biotechnology
endocrinology
numismatics
Tamar is talking about evolution with a friend. The friend says, 'It's just a theory, so I don't believe it. When they prove it and it becomes the law of evolution, then maybe I'll change my mind.' Which of these possible replies best describes scientific principles or the work of scientists?
Scientific theories do not become scientific laws; they are explanations for natural phenomena based on evidence.
Science always finds the right answer; the answers that scientists and researchers discover never change.
He should be wary of science because it is based on research and evidence, not bias and opinion.
Scientists take each other at their word regarding experimental results, and the public should, too.
Scientists and engineers do different types of work. Which statement BEST compares the methods of science and engineering?
The methods are completely different and unrelated.
The methods are similar, but are not identical with one another.
The methods are identical, but have different names.
The methods are identical and have the same names.
Dr. Sanchez and her team have observed an unusual star in the Andromeda galaxy. Their data suggests that the star is being consumed by a nearby black hole. They write a scientific paper about their work and submit it to a scientific journal. Other scientists read their paper and look for the unusual star as well. The other scientists are participating in which activity?
data collection
peer review
developing a hypothesis
developing a theory
Camille notices that the leaves of her pothos plant are drooping this morning. The leaves were not droopy yesterday. She decides the plant needs to be watered. What had Camille just done?
calculated the probability of the plant's ability to survive without water
devised a controlled experiment about the effect of water on plant leaves
formed a hypothesis based on quantitative data she has collected
made an inference based on past experience and observation
In biology, the different areas of study are connected and overlap in various ways, with concepts that cut across all disciplines. Which pair of crosscutting concepts are BEST exemplified when birds fly south when winter comes to the United States, and north when spring arrives?
stability and change; scale, proportion, and quantity
systems and system models; scale, proportion, and quantity
patterns; cause and effect
energy and matter: flows, cycles, and conservation; patterns
In the metric system, what do the kilogram, kilometer, and kilocalorie have in common?
All measure the same type of quantity, and are interchangeable.
All are units 1000 times larger than a base unit.
All are units 1000 times smaller than a base unit.
All are units 1 million times larger than a base unit.
Dr. Smith reads two research papers that present different conclusions about the same question. He knows the researcher who wrote Paper A, but does not know the authors of Paper B. When asked which paper he thinks has more merit, Dr. Smith replies, 'Paper A.' Because of Dr. Smith's personal connection to some of the researchers, he could be exhibiting
bias
inference
observation
skepticism

testing variables
watching a control group
making observations
applying a stimulus
Science began out of humankind's natural curiosity to understand and explain the interactions and processes of the natural world. Science aims to use these explanations to understand patterns in nature and benefit nature and society, as well as to address issues that face the natural world and human society. Which statement BEST reflects the efforts of scientists in pursuing the goals of science?
Scientists make observations and conduct experiments in order to establish facts.
Scientists attempt to resolve questions of belief with scientific facts.
Scientists review and revise current knowledge when new evidence arises.
Scientists emphasize data that support their hypotheses and ignore data that does not.
Which of these questions could BEST be answered with the methods of science?
How is Earth different from other planets?
What does it mean to be a good person?
Why are we here on Earth?
Will computers make us more or less human?
Which of the following is a key characteristic of a scientific theory?

It is a fact that has been proven beyond doubt.
It is an explanation of natural phenomena based on evidence.
It is a belief that does not require evidence.
What is the role of a control group in an experiment?
To provide a standard of comparison by not receiving the treatment.
To receive the treatment and provide data on its effects.
To determine the independent variable in the experiment.
To confirm the hypothesis of the experiment.
What is the primary goal of peer review in scientific research?
To ensure the research is popular among scientists.
To ensure the research supports the existing theories.
To ensure the research is original and has not been done before.
