Modern scientists continue the tradition of the Greek philosopher in their efforts to understand
the world around them. They know that the universe consists of objects, organisms, and
processes that interact in many different ways, and proper scientific methods can help this
understanding. Which two statements state the goals of science? - ANSWER A goal of science is
to generate testable explanations for events in the natural world.
A goal of science is to make useful predictions about natural events , and to understand patterns
in nature by using explanations supported by data
Scientific methodology is a well-established method used to study biological systems and
conduct experiments leading to valid results. In the methods of science, which step generally
comes before the other three steps? - ANSWER developing a hypothesis
Kari is testing the hypothesis that plants rely on photosynthesis to grow, She conducts an
experiment in which she observes the sprouting and growth of bean seeds. The beans are
raised either in sunlight or darkness. She records her observations in a data table. Which
statements from Kari's records convey qualitative data, and not quantitative data? Choose all
that apply. - ANSWER The beans in the control group have a white spot on day 2
The beans in the control group feel soft on day 2
The beans of both groups appear equally green and healthy on day 1.
The famous scientist Albert Einstein sometimes used "thought experiments" such as imagining
himself chasing a beam of light or riding an elevator in free fall. These thought experiments,
which would not be possible to conduct physically, helped him challenge current scientific
thinking and develop his theories of gravity and of special relativity. Write the words or phrases
from the box on the lines to complete the paragraph. - ANSWER In actual physical experiments,
scientists must select equipment (E) carefully and avoid errors (A) in data collection and
analysis. There is variation in nature, so the larger the sample size (D) , the more accurately
researchers can determine dissimilarities within each group, and analyze variances between
,experimental groups and controls. When interpreting data, researchers use statistical analysis
(F) to decide if an experimental treatment is significantly different from the control group. When
drawing conclusions, the hypothesis (B) being tested may either be supported, or refuted and
revised (C) to be tested again.
When, if ever, can a scientific theory becomes a scientific law? - ANSWER never, under no
circumstances
A scientist is designing an experiment on tomato plants. Which is the best example of
hypothesis that the experiment could test? - ANSWER Increasing the amount of sunlight that a
tomato plant receives will increase its height.
Francesca, a PhD candidate, conducts extensive research on aluminum corrosion. When
finished, she will submit her research data and conclusions in a report to a scientific journal for
peer review. What are three benefits of peer review? Select three answer choices. - ANSWER
Peer review allows other scientists the chance to try and replicate the experimental results
Peer review can lead to new ideas and further study.
Peer review helps check for mistakes, bias, or fraud in a set of experimental work.
Society expects scientists to follow ethical practices and meet many ethical standards. Which is
an example of one of those ethical standards? - ANSWER Analyze data that was truly observed,
and not data that was expected or desired.
Scientists are often faced with ethical questions, or questions of right and wrong. Which of the
following situations involve the need for an ethical decision or resolution?
I. Mairead wants to include a hypothesis in her report, and she asks if she must give credit to
the scientist who first proposed it.
II. Aiden is planning and experiment on gerbils, and he asks how large the cages should be.
III. Paula is developing a new technique for mining fossil fuels, and she asks if the technique
must avoid polluting the experiment. - ANSWER I.,II.,and III.
, which task would be best accomplished in a field of engineering? - ANSWER designing and
building an artificial heart for the human circulatory system
Fill in the paragraph - ANSWER Living things are similar in many ways. Genes made of DNA (A)
carry the directions for inheritance, and offspring usually resemble their parents. With asexual
reproduction (G) , offspring have the same traits as their parents. With sexual reproduction (F) ,
offspring differ from their parents in some ways, Living organisms use energy and materials to
grow ,develop, and reproduce. These life processes involve a set of chemical reactions called
metabolism (B) . Organisms have means of detecting a change in their environment and
responding to this stimulus (D) . Most organisms require that their internal environments
remain in a fairly constant range, and so they maintain homeostasis (E) . The ability of a group
of organisms to change, or evolve (C) over time helps populations survive in an ever-changing
environment.
No single characteristic alone can't describe a living thing, but all living things share certain
characteristics. Which is NOT one of these characteristics? - ANSWER ability to move from place
to place
DeShawn is studying homeostasis and circulation. To organize his findings, he constructs two
models: one to represent a non-smoker, and one that includes attributes typically found in a
smoker. By comparing the two models, which relationship of cause and effect can DeShawn
BEST explain? - ANSWER Smoking damages the function of the circulatory systems
Look at the pictures. Which crosscutting concept of biology do these phenomena BEST
represent? - ANSWER Patterns
Scientists use the metric system when gathering data and performing experiments, Which of
the following statements about the metric system are true? Select three correct answers. -
ANSWER The units of the metric system are scaled on multiples of 10, making mathematical
calculations easier to perform.
