Answer:
4) theory
Explanation:
Science is a branch of study that deals with answering questions and solving problems. However, there are different scientific principles used to tackle the problems in science. One of them is a THEORY, which is a detailed and well explained fact about a natural phenomena. A theory is said to be an hypothesis that has been subjected to series of experimental testing and found to be accurate or consistent.
In this question, a series of experiments was designed and conducted by several science teachers around the world. The results were found to be consistent that students who stayed up all night playing before their finals did -40% worse than students who didn't. This comprehensive and well explained observation using repeated experiments depicts a THEORY.

Coral can be a good food source, which it is fished for people all over. But too much of it can be bad for coral reefs.
Using nets instead of bad fishing devices can lead to fish eating algae which is good for the ecosystem.
Traps that are too close to coral reefs can damage them, leading to death or a long time to recover.
The two species probably had a common ancestor, but split and changed from evolution.
Ummm that would be false cuz it makes no sense
