Answer: The choice of a submarine to either sink or float depends on the captain of that submarine. For a submarine to sink the captain just have to allow water to fill the water tank (lock), making the submarine more dense than the water it has displaced. For it to float, it just have to empty the water tank and allow air to fill it.
When a boat in a canal lock sank, the water level will rise, because the volume of the boat has displaced more water, and this displaced water will cause the water level to rise. The space occupied by an object in a water, is equal to the volume of water been displaced.
A pedigree allows for simple organization of a family tree and any possible disease that may be passed on. It is better than a written passage because it is visual; people can see the pattern of inheritance.
Pedigrees are organized like a family trees. The first ancestors are at the top, and their progeny are connected below them. As a result, this makes the pattern easy to follow.
