In: Biology

Answer 1

Think of a mummy, all dried out and crispy. It would crack if it moved. Its blood can’t move. Its muscle cells can’t change shape, which is what makes muscles move. Its brain can’t send electrical impulses to the rest of the body to make it function, because electricity is conducted through water. We need water for every system in our body to be able to move, otherwise they’ll just be frozen in place.
