Question

1. according to the cell theory, what is required for an object to be considered alive?
2. how did improvements in the microscope help scientist form the cell theory?
3. use the appropriate phrases to complete the venn diagram comparing the terms law and theory.

• supported by large amount of data
• based on hypotheses
• can be modified
• constantly changed as more information is gathered
• used to make predictions.
• a summary of many experimental results and observations
• can be reduced to mathematical equations
• explains a wide range of observations and experimental results.
• describe what nature does under certain characteristics.

Explanation:

1. According to the cell theory, for an object to be considered alive, it must be composed of cells, and cells must come from pre - existing cells.
2. Improvements in the microscope allowed scientists to see cells more clearly and in greater detail. This led to the discovery of cells in different organisms, which in turn helped in formulating the cell theory.
