Question

question 12 of 25 which statement is a scientific theory? a. the various functions of different types of cells can be determined by experiments. b. the interactions between cells can be predicted with mathematical equations. c. most cells are so small that they can be observed only through a microscope. d. cells are the fundamental units of all living organisms.

Explanation:

A scientific theory is a well - substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experimentation. Option A describes functions determined by experiments which aligns with the nature of scientific theories. Option B is about mathematical equations for cell interactions which is more of a model or calculation rather than a theory. Option C is a simple statement about cell size and observation, not a theory. Option D is a basic biological fact, not a theory.

Answer:

A. The various functions of different types of cells can be determined by experiments.
