BIO 200 EXAM ONE UPDATED ACTUAL QUESTIONS
AND CORRECT ANSWERS
Question:
1. What is biology?
Answer:
the scientific study of life
Question:
2. How can we build our understanding of life?
Answer:
multiple levels:
- the molecular mechanisms within the cell
- the integrated actions of cells within an organ or individual
- the interactions among different organisms in nature
Question:
3. How do we define science?
Answer:
a way of knowing and understanding about the world/universe
a way of obtaining more knowledge based on what is OBSERVABLE (directly or
indirectly)
Question:
4. is there a single, stepwise pathway to new knowledge
about the world?
Answer:
No
discovering information is not linear.
the scientific method is replaced by scientific inquiry
,Question:
5. what are the steps of scientific inquiry?
Answer:
Ask Questions (Make Observations, State a Problem, Gather Information, Infer),
Hypothesize (possible explanation for an observation),
Make a Prediction (statement of what you think will happen in the next sequence
of events),
Test Hypothesis (Design an experiment, Make a model, Gather and Evaluate
evidence, Collect Data, Record Observations),
Analyze Results (Graph Results, Classify Information, Make Calculations), --- IF
INCONSISTENT, reject hypothesis ---- IF CONSISTENT, becomes a theory
Draw Conclusions (Infer, Reasoning) / establish a theory
Communicate Results (Write Scientific Journal Articles, Speak at Science
Conferences, Exchange Information on Internet).
Question:
6. how do we learn new things? what is the goal of learning
new things?
Answer:
combine observations and questions with logical reasoning
the goal is to MAXIMIZE OBJECTIVITY
Question:
7. what is a hypothesis and what does it lead to?
Answer:
a testable explanation of a question generated by observations
leads to predictions
to be a specific hypothesis, it has to be something we can test
Question:
8. what are experiments?
Answer:
specific tests of hypotheses and their predictions
Question:
9. how do we test experiments?
Answer:
using logical reasoning (to be objective as possible) to generate expectations and
predicitions
formal reasoning and if-then statements
, Question:
10. what is the thing we manipulate in experiments
Answer:
the independent variable(s)
Question:
11. what is the thing you observe/record
Answer:
the dependent variable(s)
Question:
12. what are treatments
Answer:
groups of experimental units that experience the exact same conditions
Question:
13. what are replications?
Answer:
the number of repeats
Question:
14. why are controls important / what are they?
Answer:
control variables hold constant ALL of the possible factors except the one your
experiment is investigating
makes sure that the factor your investigating is the only variable affecting the
outcome
you're controlling the other things that might be interfering
Question:
15. what are control treatments?
Answer:
"controlled" experimental units for comparison to "manipulated" experimental
units
this is the one that gets the zero level
this one for ex. will get NO fertilizer to see how much a plant grows
