BIO Beyond Midterm Review Exam With100% Correct And Verified Answers 2024
What is science? - Correct Answer-knowledge about the natural world
What do scientists do? - Correct Answer-use research and experiments to learn about
the natural world
Confirmation bias: - Correct Answer-Confirmation bias vs inattentional blindness vs
objectivity (The Brain) - existing theory is interpreted as confirmed with new info; info is
ignored due to focusing on other info; Objectivity: not influenced by personal opinions
Inattentional blindness: - Correct Answer-Countering bias examples (Countering Bias:
Objectivity) - Objectivity: based on fact (pyramids appear around the world in different
cultures); Subjectivity: based on opinion (the odd statues at Easter Island depict alien
life)
d. - Correct Answer-Random error vs systemic error (Instrumental Error) - Random
error: error without a specific cause or pattern; Systemic error: error that has a very
specific cause or pattern
e. - Correct Answer-Pinpoint the difference between an accurate vs precise
measurement (Accuracy & Precision) - Accurate measurement is closest to the actual
measurement (close to target); Precise measurements are closest to other
measurements (close to one another)
f. - Correct Answer-The steps of the scientific method (Experimental Design) - Purpose,
Research, Hypothesis, Experiment, Analysis, Conclusion
2. - Correct Answer-Scientific Tools
a. - Correct Answer-SI unit for length, mass and volume (SI Units) - meters, grams,
liters, kilometers
b. - Correct Answer-Calculating volume with V=L x W x H (Cubic Units) - 100 * 50 * 50 =
250,000 cm^3 = 250,000 milliliters = 250 liters
c. - Correct Answer-How to write in scientific notation (Scientific Notation) - 100 = 1 *
10^2; .001 = 1 * 10^-3
d. - Correct Answer-Views of Ptolemy, Copernicus, Kepler and Einstein on the solar
system (Models) - Ptolemy: epicycle (stars move across the sky; Copernicus: sun is the
center of the universe (still used epicycles); Kepler: ellipses (not epicycles); Einstein:
space and time warp due to gravity and general relativity (E=mc^2)
, 3. - Correct Answer-Scientific Skills
a. - Correct Answer-Reading data from a table and choosing best key factors (The
Maker Club) - Second least expensive, highest capacity per gram, lowest level of
capacity
b. - Correct Answer-Graphing linear time (Carl's Commute) - 7:00 = 7.0, 7:15 = 7.25,
7:30 = 7.5, 7:45 = 7.75
c. - Correct Answer-Independent vs dependent variable (Carl's Study Habits) -
Independent: is not changed by observer (days of the week, temperature, traffic, etc.);
Dependent: the variable that is manipulated by the observer (when we leave, what we
eat, trip duration, etc.)
4. - Correct Answer-Graphing Skills
a. - Correct Answer-Identify independent and dependent variables and plot them on a
graph (Plotting Points) - independent: x-axis; dependent: y-axis
b. - Correct Answer-Inverse (indirect) vs direct correlation (Trends and Relationships) -
Direct correlation: data cannot conclusively prove a cause-and-effect relationship
between independent and dependent variables
c. - Correct Answer-Relationships shown on different types of graphs: sinusoidal,
logarithmic, sigmoidal and exponential (Variable Relationships) - Sinusoidal: smooth
change from one state to another (smooth wiggle wave); Logarithmic: rapid increase
before reaching a plateau or limit (fast growth then levels off); Sigmoidal: rapid rise from
one level to another ( ∫ almost); Exponential: the most rapid growth without stopping
d. - Correct Answer-Normal vs skewed distributions shown on a graph (Distributions) -
Normal: bell curve; Skewed: "pushed to one side or the other
5. - Correct Answer-Written in Stone
a. - Correct Answer-Sequence the events using a rock column (Construct a Rock
Column) - earliest (longest ago from present) is the lowest layer of rock; most recent
(current top layer) is the closest to the top
b. - Correct Answer-How the following rocks are made: igneous, sedimentary and
metamorphic (Finding the Age) - igneous: melted rocks cooled back down; sedimentary:
layers and layers of different types of rock cemented together; metamorphic: exposed to
high temperature and pressure
6. - Correct Answer-End of an Era (Hell Creek, USA)
