Scientists in all branches of science have developed scientific theories. Which of the following statements is true about all scientific theories?
Scientific theories are not widely accepted when they are first developed.
Scientific theories are based on large amounts of evidence.
Scientific theories will become scientific laws if enough scientists support them.
Scientific theories are based on the work of individual scientists.
New evidence can cause scientists to revise a scientific theory. If new evidence comes to light, which is most likely to happen?
The theory will be discarded immediately.
The new evidence will be ignored.
The theory will be revised immediately.
After years of research, if the evidence still supports a change, the theory will be revised.

It does not represent the main parts of a cell.
It does not contain the correct number of nuclei.
It cannot represent a living cell, since a true cell is three-dimensional.
It cannot represent a living cell, since the cytoplasm should be in constant motion.
