No, I don't reckon that water is alive. I don't think that it is "dead" either. It simply just... exists. However, it DOES hold life within it. But the water itself is not alive, because for something to be considered "alive", it must meet the requirements of responding to stimuli, reproducing and growing, and must be dependent on its environment. Water itself cannot be dependent on an environment, because it IS an environment.
This is just my opinion though :)

D - spine alignment and foot size.
It was only the late Australopiths that had an S-shaped spine. This allowed for them to be bipedal, that is, the ability to walk on two legs as we do. This is because the S-shaped spine allowed them to balance when they were standing. The late Australopiths also have shorter and less flexible toes. These smaller, but sturdier feet made pushing off the ground much easier - aiding in their bipedalism.
