Final answer:
The correct answer is D) all of the above, which means scientific theories are based on several hypotheses, are broad in scope, and are based on natural laws.
Step-by-step explanation:
Which of the following is true of scientific theories? The correct answer is D) all of the above. Let's look at the aspects of scientific theories:
- Theories are based on several hypotheses that have been tested and supported by evidence.
- Theories are broad in scope because they unify several known facts about the world and help provide an overarching explanation for natural phenomena.
- Theories are based on natural laws, which describe patterns observed in the natural world, such as those pertaining to gravity, relativity, atomic theory, etc.
Scientific theories aggregate multiple observations and experiments into cohesive principles that explain and predict natural phenomena. They are well-supported explanations that are robust and able to stand the test of new evidence.
