Which of the following best explains the importance of water to humans?
V125BC [204]
All of the above.

Water is essential, you can only survive an average of 3 days without it. (some people have survived for longer though.)

Water is important for shipping and trade, because, ships. They go across water. Trade happens. It's hard to fit a lot in airplanes and you have to monitor it's weight slowly. Across land, it's also hard to fit a lot in random trucks driving across what was an ocean. (it would also be much more tedious) It's also one of the cheapest ways.

It is, I guess. There is a high demand for water, and a limited amount as well. It would also be profitable because you can get water easily, or something. (I don't really know for this one but the other two are true so I guess you can't select two so yeah.)

julsineya [31]
A. He should add shells that are different colors, but the same size and type, to the tank and observe which shells the hermit crabs choose.

Durning an experiment you need to keep everything the same but only change the certain things based on your theory.
Such as how the student wanted to see if the color attracted the crab. If he had changed the size and type of the shell then the crab would have chosen the bigger one as they tend to grow into larger shells.
