which of the following best explains why what we know about cells is called a theory and not a law?
o a we do not have enough evidence yet to call cell theory a law.
o b we have not reviewed cell behavior enough yet to call it a law.
o c cell theory is still changing but may eventually become a law.
o d cell theory explains cell behavior where a law would describe it.

the most basic concepts of cell theory are that cells are the basic units of life and that all living things are made of cells. which answer correctly explains why these concepts are the basis of a theory and not a hypothesis?
o a cell theory explains how cells function rather than predicting how they function.
o b cell theory does not change and as a result can be accepted as fact.
o c cell theory is a prediction based on observation and not a fully accepted idea.
o d cell theory remains largely untested rather than being subject to testing.

Explanation:

• For the first question: A scientific theory explains phenomena (cell behavior in this case), while a law describes a relationship or pattern. Cell theory explains cell behavior, so it's a theory. Options a, b, and c are incorrect as there is sufficient evidence, cell theory is well - reviewed, and it's not just a changing idea that will become a law (they are different concepts).
• For the second question: A hypothesis is a tentative prediction. A theory is more comprehensive and explains how something works. Cell theory explains how cells function (which is more in - depth than a simple prediction), so it's a theory. Option b is wrong as cell theory can be updated. Option c is incorrect as it's more than just a prediction. Option d is wrong as cell theory is well - tested.

Answer:

First question: d. Cell theory explains cell behavior where a law would describe it.
Second question: a. Cell theory explains how cells function rather than predicting how they function.
