Answer 1

B. All living organisms are composed of one or more cells, which came from pre-existing cells.

Step-by-step explanation:

Scientific theory is given as an answer to a natural happening in the earth but scientific laws are detailed idea of how nature will act under certain conditions.

Theories are given after an experiment has been performed under controlled conditions. Scientific theory cannot be changed to scientific laws and scientific laws cannot be changed to scientific theory.

Scientific theories are broader in scope, and give overall clarifications of how nature functions and why it shows certain attributes. Similarly, all cells comes from pre-existing cells is an example of cell theory.
