What are the roles of test groups in scientific investigation?
Both are experimental groups, and each individually show the effects of an experiment.
One is the experimental group and one is the control group, and together they show the effects of an experiment.
Both are control groups, but only the control group shows the effects of an experiment.
Both are experimental groups, but only the experimental group shows the effects of an experiment.
Your friend, Alfred, conducts an experiment once and asks if his hypothesis should be classified as a theory. Which is the best response to Alfred’s question?
Yes, because his data supports the hypothesis.
Yes, but only if additional experiments show similar results.
No, because the experiment did not provide enough data to support the hypothesis.
No, because a theory is a highly reliable explanation that incorporates many well-tested hypotheses and evidences.
Cell theory has become the central organizing principle of biological science. Could this scientific theory ever become a scientific law?
Yes, if scientists decide that enough evidence supports the theory.
Yes, if the theory is shown to predict future events.
No, because a theory is a complex explanation that does not become a law.
No, because a theory can be proven correct while a law cannot be proven.
After a team of scientists completes an investigation, they submit an article about the investigation to a scientific journal. Before the journal publishes the article, they send it to other scientists for an anonymous, independent review. What is the purpose of this peer review?
To evaluate the methods, and validate the results of the investigation
To guarantee that the conclusions of the investigation are absolutely correct
To make sure the investigation has practical, economic benefits
To improve the appeal of the article to the general public
Testing hypotheses often involves designing experiments. Which of the following is the factor that is observed and measured in an experiment?
Control group
Experimental group
Dependent variable
Independent variable
During the earthworm behavior lab, we observed and recorded written data describing earthworm responses to different stimuli. What kind of data was this considered?
Quantitative measurements
Testing a control group.
Qualitative observations.
None of the above.
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 bias and opinion, not research and evidence.
Scientists always take each other at their word regarding experimental results, and the public should, too.
You wanted to study the organelles inside of a single-celled algae. To look at the mitochondria of the already dead algae, which is the best type of microscope you should use?
TEM (Transmission Electron Microscope)
SEM (Scanning Electron Microscope)
Compound Light Microscope
Dissecting Microscope
In the earthworm behavior lab, we were trying to determine how well earthworms taxis behavior to different stimuli. We used different types of stimuli (water, vinegar, and light) and observed the response of the earthworms. Which of the following best describes the independent variable in this experiment?
The response of the earthworms.
The positive and negative movement of the earthworms.
There was no independent variable.
The different types of stimuli.
Which of the following best describes the three parts of the cell theory?
All living things are made up of one or more cells, the cell is the basic unit of structure, and all cells are spontaneously generated.
All living things are made up of one or more cells, the cell is the basic unit of structure, and all cells come from pre-existing cells.
All living things are made up of more than two cells, the cell is the basic unit of structure, and all cells come from pre-existing cells.
None of the above.
Which of the following is a strong scientific question?
How do earthworms respond to different stimulus in their environment?
What is the best color?
Why are we here on Earth?
Which flower is the prettiest?
Honeybees are on the verge of extinction due to human activities and climate change, but are crucial to the survival of ecosystems because of their niche as pollinators. Scientists are frantically looking for ways to replicate how honeybees act as pollinators in an environment by looking at how much pollen they transfer from flower to flower, in case they do go extinct. Which type of microscope would be best for this type of research?
Compound Light Microscope
Dissecting Microscope
TEM (Transmission Electron Microscope)
SEM (Scanning Electron Microscope)
An enzyme is a molecule that speeds up a reaction. In living things pH affects an enzyme's ability to speed up a reaction. If the pH is too high or too low the enzymes stop functioning. Based on the graph, the enzyme pepsin functions best in what pH level?
1
8
7
3
Which of the following best summarizes why the technological invention of microscopes was important to biology?
It allowed for the development of cell theory by being able to investigate and collect data on cells.
It created a means of funding for cell research.
It created public interest and support for research.
It proved that cells could form spontaneously.
You wanted to study bacterial infections by investigating how colonies of living bacteria react around live human cells. Which is the best type of microscope you should use?
TEM
SEM
Compound Light Microscope
Dissecting Microscope
The graph shown represents data collected that compares Monarch butterfly appearance to Milkweed appearance in different areas. Based on the graph, which is the best conclusion can you draw?
The Milkweed and Monarch usually appear first in coastal areas.
The Milkweed and Monarch usually appear last in inland areas.
Monarch butterfly appearance usually comes after Milkweed appearance.
Monarch butterfly appearance on average will start before 150 days.monoa
Scientific law and a scientific theory are similar in that both
Are based on what we expect to happen based on natural history
Describe the events that cannot be observed in nature
Explain why events and conditions occur as they do in the natural world
Represent a large amount of scientific investigation and evidence
Viruses are not made of cells. Do most scientists consider a virus a living thing?
Yes, even though they are made of cells, they still exhibit characteristics of life without a host cell.
Yes, they are living things because they contain DNA.
No, they do not contain DNA or other essential macromolecules.
No, they are not made of cells and do not exhibit characteristics of life without a host cell.
Which of the following describes the best procedures when using/focusing a microscope?
Always start with the low objective lens, and only use the coarse adjust knob on the high objective lens.
Always start with the scanning objective lens, and only use the fine adjust knob on the high objective.
Always start with the low objective lens, and only use the fine adjust knob on the high objective lens.
Always start with the scanning objective lens, and only use the coarse adjust knob on the high objective lens.
What is the most basic (smallest) functional level of organization/life?
Organisms
Cells
