Positive (Rises) , neutral (Level) and negative (Sinks) buoyancy .
There are only three types of buoyancy. Positive, Neutral and Negative. Positive rises, neutral is in between meaning its in the center and negative sinks. Your welcome
Yes, if the buoyancy is greater.
Virtually all human beings have a net density that is slightly less than 1, allowing them to float in water.
No, it does not. Buoyancy keeps things afloat in water.

Positive Buoyancy. When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.

Buoyancy; negative density.
Negative buoyancy is when the gravitational pull on a diver is greater than the buoyant force. This means that the diver is being pulled downward, and that the buoyant force is doing negative work (work that is in the opposite direction of the displacement). Positive buoyancy is the opposite situation in which the buoyant force of the diver is greater than the gravitational pull, which makes the diver move upwards. Usually, a person's weight is slightly more than the weight of the displaced amount of water. For example, a person who weighs 80kg displaces 79dm2 of water, which weighs 79kg, that is, he has about 1kg of negative buoyancy. As for your question whether this negative buoancy is a unique feature for black people, the answer is no. it is related to the person's density.
A submarine has a variable buoyancy due to it's ballast tanks. When a submarine submerges, it fills it's ballast tanks with water which causes negative buoyancy. When a submarine surfaces, it pumps the water out of the ballast tanks thus giving it positive buoyancy.
Negative buoyancy occurs when an object displaces less than its mass of whatever its not floating in. A liter of water has a mass of 1kg, but displaces less than 10g of air, so water sinks in air.

People knew that some things floated in water long before writing was invented. The first person to establish the rule that controlled buoyancy was Archimedes.
No, it does not. Buoyancy keeps things afloat in water.
