estion 1 - 19
ich of the following best explains how the cell theory was developed?
cells are so diverse that scientists had to come up with an explanation that would apply to all types of cells.
mutations occur and cause changes in cells, so scientists could not develop a law that would apply to all forms of cells.
the cell theory is a well - tested explanation of observations that was formed from the contributions of several different scientists.
the cell theory was developed through extensive library research, because it would be impossible to test all living things for the presence o

Explanation:

The cell theory is a scientific theory. Scientific theories are developed through the contributions of multiple scientists over time. They are based on extensive observations and testing. The first option about cell diversity is not the main reason for the development of the cell theory. The second option about mutations not allowing a law is incorrect as the cell theory is a theory, not a law. The fourth option is wrong because the cell theory was not developed just through library research but through actual scientific investigations (like microscopy - based observations by Hooke, Schleiden, Schwann, etc.). The third option correctly states that the cell theory is a well - tested explanation formed from contributions of several scientists.

Answer:

The cell theory is a well - tested explanation of observations that was formed from the contributions of several different scientists.
