C. a hypothesis or group of related hypotheses that can be accepted as true based on repeated experimentation with similar results
Answer:
Correct answer: B). A statement of fact that is generally accepted to be true and universal because it has always been observed to be true.
Explanation:
A scientific law may be defined as the something that appears to be true and is universally applicable. Scientific laws do not explain why the observed events happen, but it only states that the event occurs in the same way over and over. Example of scientific law is a law of gravity.

The term Doping is essentially what athletes on Erythropoietin or EPO commonly known as use. It increases the production of red blood cells in the bone marrow. Erythropoietin is usually produced by the kidneys when oxygen in the blood gets to low levels.
The prime regulator of red cell production is erythropoietin and its major functions are to:
- Promote the development of red blood cells.
- Initiate the synthesis of hemoglobin, the molecule within red blood cells that transports oxygen.
Hope this helps you out.
