experimental group
a population
2
A controlled experiment is one that
include experimental and control groups tested in parallel
is repeated many times to make sure the results are accurate
is slow so scientist make careful records of the results
keeps all environmental variables constant
3
Which of the following best describes the logic of hypothesis based science?
If my prediction is correct, it means a testable hypothesis
If my hypothesis is correct, I can expect certain results
If my observations accurate, it will support my hypothesis
If my experiment is valid, it leads to a testable hypothesis
4
Protists and bacteria are grouped into different domains because
bacteria decompose protists.
protists are photosynthetic.
protists have membrane-bounded nucleus,bacterial cells dont
bacteria are not made of cells.
5
Which of the following statements best distinguishes hypotheses from theories in science?
Hypotheses = guesses; theories = correct answers
Theories= proved true always hypotheses= falsified by tests.
Hypotheses =narrower scope; theories = broad explanation
Theories are hypotheses that have been proved
6
Which of the following best demonstrates the unity among all organisms?
natural selection
the structure and function of DNA
descent with modification
emergent properties
7
Systems biology is mainly an attempt to

simplify complex issues by reducing systems to smaller units
Speed up technological applications of scientific knowledge.
interpret & integrate all levels of biological organization

Which of the following is an example of qualitative data?
The contents of the stomach are mixed every 20 seconds.
The fish swam in a zig-zag motion.
The six pairs of robins hatched an average of three chicks.

9
Which is not an observation or inference Darwin's theory of natural selection is based on?
A population becomes adapted to its environment over time.
Poorly adapted individuals never produce offspring.
There is heritable variation among individuals.
Overproduction of offspring means competition for resources.
