Explanation:
There should be another answer that can be chosen: the rat’s chemical receptors detect chemicals in the fruit that alert the rat to possible danger. Sensory receptors in the rat's whiskers respond to input about the texture of the fruit, maybe it's slimy or rancid, if if it was another factor such as the environment, it wouldn't have approached the fruit in the first place.

Answer: 1, 2, 4 are accurate.
Explanation:
1. Joe is on a hill (on a trail) above the ocean. The beach and ocean are at similar altitudes. Therefore Joe is at a higher altitude than if he was at the beach.
2. Since Joe is on a hill, he has a higher altitude than at sea level. Air at a higher altitude has lower density because there is less air "ontop" of itself than at lower altitudes. As well, his hill is above the ocean, which means there is a lot of water, making the air more humid than where he is. Humidity also makes air denser.
4.The air pressure will decrease if Joe goes up to higher altitudes because there will be less air on top of itself.
B water pollution is the answer
