BIO 155 - Intro to Biology Actual study
set with Questions and correct/verified
Answers
Science - ANSWER-A process of using observations and experiments to draw evidence-based
conclusions. (a pathway by which we can come to discover and better understand our world)
Scientific thinking - ANSWER-Self-correcting and based on experience and observations that are rational,
testable, and repeatable
Limits of science - ANSWER-- Can be applied only to the observable and measurable natural world
- Cannot tell us what to do with the information it uncovers
- Provides no help as to what is morally or ethically right or wrong
- The objects of scientific study must be observable and quantifiable
What can't science do? - ANSWER-- Speak to the existence of God or any supernatural event or creature
- Distinguish or quantify "beauty" or lack thereof
- ANSWER all questions
Biology - ANSWER-The study of living things
Biological literacy - ANSWER-Ability to use the process of scientific inquiry to think creatively about real-
world issues in order to communicate those thoughts to others and integrate them into your decision
making
Step one of scientific thinking - ANSWER-Make observations about the world around you
Step two of scientific thinking - ANSWER-Formulate a testable (supported or rejected by experiments or
non-experimental studies) and falsifiable hypothesis (can be ruled out by data)
Step three of scientific thinking - ANSWER-Prediction: propose a situation that will give a particular
outcome if your hypothesis is true but a different outcome if your hypothesis is not true
Example: If the toaster does toast, then the hypothesis is supported —likely correct
If the toaster doesn't toast, then the hypothesis is not supported — likely incorrect
- What follows the "if" is the independent variable and what follows the "then" is the dependent variable
Step four of scientific thinking - ANSWER-Experimentation: an experiment is a repeatable manipulation
of one or more aspects of the natural world
Independent variable - ANSWER-A variable that stands alone and isn't changed by the other variables
you are trying to measure
, Dependent variable - ANSWER-The outcome factor, the variable that responds or could potentially
respond to changes in the independent variable
Controlling variables - ANSWER-- The most important feature of a good experiment
- The attempt to minimize any differences between a control group and experimental group other than
the treatment itself
Treatment in controlling variables - ANSWER-Any experimental condition applied to individuals
Experimental group - ANSWER-A group of individuals who are exposed to a particular treatment
Control group - ANSWER-A group of individuals who are treated identically to the experimental group
with one exception: they are not exposed to the treatment
Variables - ANSWER-Characters of your experimental system that are subject to change (independent
and dependent variables)
Step five of scientific thinking - ANSWER-Draw a conclusion and make revisions: look for patterns and
relationships in evidence
- Determine if findings and conclusions support a hypothesis
- If the result is not what you expected, that does not make it a "wrong ANSWER," you might just need to
adjust your hypothesis and conduct additional experiments
Blind experimental design - ANSWER-The experimental subjects do not know which treatment (if any)
they are receiving
Double-blind experimental design - ANSWER-Neither the experimental subjects nor the experimenter
knows which treatment the subjects are receiving
Randomized - ANSWER-The experimental subjects do not know which treatment (if any) they are
receiving
Repeating experiments - ANSWER-Replication: process of repeating a study (increases confidence in
results and helps isolate variables responsible for outcomes of experiments)
- Experiments that can be repeated again and again are an effective defense against biases
Visual displays of data - ANSWER-Can help us understand and explain phenomena
Statistics - ANSWER-- Can aid in making decisions
- A set of analytical and mathematical tools designed to help researchers gain understanding from the
data they gather
- Drawing conclusions based on limited observations is risky
- Can also help us to identify relationships (or the lack of relationships) between variables
Positive correlation - ANSWER-When one variable increases, so does the other
