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.

Answer:
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change .
Excess carbon in the atmosphere warms the planet and helps plants on land grow more. Excess carbon in the ocean makes the water more acidic, putting marine life in danger. Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt.
