1. Is the water you drink the same water that Dinosaurs drank?
The Hydrogen and oxygen in it is the same. Photosynthesis, IIRC, breaks water down into hydrogen and oxygen, before joining it with Carbon dioxide to form carbohydrates and oxygen. Theoretically, some of the water might be the same.

Depends on what you mean "can" eat or drink, and what you mean by water-based. Salt is not water based. YOu can eat it, but it won't provide nutrition. Pure fat has no water in it (although water is needed to create it, and one of the breakdown products is water). It's a question that requires defining.

Not 100%. Nerve signals propagate electrically down the membrane of a single nerve cell, but the signal propagates between nerve cells using chemicals that are released by the sending cell, and picked up by the receiving cell. Nerve cells are among the longest in the body. |
