BIOLOGY EXAM 1: CHAPTERS 1-3 UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
Question:
1. Hypothesis
Answer:
must be testable and falsifiable; an educated prediction that can be tested
Question:
2. Prediction
Answer:
making an educated guess as to what might happen based on observation
Question:
3. Experiments
Answer:
a test under controlled conditions that is made to demonstrate a known truth, to
examine the validity of a hypothesis, or to determine the efficacy of something
previously untried; the process of conducting such a test
Question:
4. Scientific Theory
Answer:
a well-substantiated explanation of some aspect of the natural world, based on a
body of facts that have been repeatedly confirmed through observation and
experimentation
Question:
5. Control group
Answer:
a group of subjects that are not given the treatment being tested in order to serve
as a benchmark for the tested group
Question:
6. Experimental group
Answer:
a group of subjects who are exposed to the variable under study
, Question:
7. What are the components of the scientific method?
Answer:
1. observation 2. hypothesis 3. experiment 4. conclusion
Question:
8. What are the limitations of science?
Answer:
can't involve the supernatural; hypothesis should be testable and falsifiable
Question:
9. Qualitative Data
Answer:
descriptions
Question:
10. Quantitative Data
Answer:
numbers/measurements
Question:
11. Molecules
Answer:
a group of atoms bonded together, representing the smallest fundamental unit of
a chemical compound that can take part in a chemical reaction
Question:
12. compound
Answer:
a substance consisting of 2 or more elements in a fixed ratio
Question:
13. Chemical bonds
Answer:
elements can combine to form compounds; only electrons are directly involved in
chemical reactions
Question:
14. Electronegativity
Answer:
is a measure of the tendency of an atom to attract a bonding pair of electrons
