Questions and Answers 100% Solved
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? - ✔✔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? - ✔✔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. - ✔✔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. -
✔✔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? - ✔✔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? - ✔✔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. - ✔✔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? -
, ©JOSHCLAY 2024/2025. YEAR PUBLISHED 2024.
✔✔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. - ✔✔I.,II.,and III.
which task would be best accomplished in a field of engineering? -
✔✔designing and building an artificial heart for the human circulatory
system
Fill in the paragraph - ✔✔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
