Hi
Inside your ear there is water this water is detected in your ear and a signal is send to your brains so you know your balanced. If you have an infection. This signal is blocked so you can't feel if you're balanced or not.
When a body is partly or completely immersed in water (or any other liquid), then:Loss in weight of body = Weight of water (liquid) displaced by the body = Buoyant force or upthrust exerted by water (any liquid) on the body. It was Archimedes who first observed that bodies lose their weight when immersed in water.
True. Things such as a sponge, placozoa and stuff can be unicellular. But other bigger animals are multicellular, like a whale or dog.
There are many traits that are determined by genetics alone, blood type, eye color and height.
