How does the history of Cell Theory illustrate the nature of science?
Scientific theories can change based on new evidence
Scientific theories are the same as laws and never change
All hypotheses are eventually proven to be true with enough experiments
Once something new is discovered, it only takes scientists a couple years to figure out how it works
A scientist develops a hypothesis, designs an experiment, and obtains data that
support her hypothesis. Which of the following best describes when a hypothesis
becomes a theory?
When the official scientific method is followed
When it is supported by consistent data from many experimental trials
When one good set of scientific data supports a theory
When it is published in a scientific journal

Cell W
Cell X
Cell Y
Cell Z
The picture shows a student using a microscope to study a prepared slide of a single-celled organism. A single-celled organism can be classified as a prokaryote based on the absence of -

Membrane bound organelles.
Ribosomes
Genetic material (DNA or RNA).
All of the above
