fish need to move through three dimensions and their buoyancy has to adjust so the fish can swim efficiently. they also create different pressures with their fins so they can maintain a certain depth in the water.

A body is just floating in a liquid. if the body is pressed down and and released what will happen?
If a body is floating IN a liquid, it has neutral buoyancy- does not go up or down. If it is floating ON a liquid, it has positive buoyancy. Neutral- when pressed down, body moves down- and when released, it stays there. Positive buoyancy- moves down, when released returns to it's position on top of the liquid.
What if buoyancy is the property of matter that can be defined as?
Buoyancy is a force exerted by a fluid against an immersed object.
What structure is used by the chambered nautilus for buoyancy?
while the chambered nautilus for buoyancy on the ancestral mollusc's shell.
When does an object have positive buoyancy?
A body has positive buoyancy when its density is lower than the density of the fluid the body is in.
Does buoyancy have anything to do with your human body being able to absorb water?
no, buoyancy is when something floats on water
What has neutral buoyancy?
a submarine
What is neutral buoyancy and how might it be a survival mechanism?
Neutral buoyancy is the ability to float under water. This allows the animal to save energy.
What are three types of buoyancy?
Positive (Rises) , neutral (Level) and negative (Sinks) buoyancy .
What kind of buoyancy do submarines have when they are resting on the surfce of the ocean?
Positive Buoyancy. When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.
What are the types of 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

What kind of buoyancy did the first submarine have?
almost neutral
How do they maintain buoyancy?
fish maintain buoyancy usind a organ near there gills wich fills with oxygen and keeps the fish afloat
Objects that are in the middle of water?
Objects that are in the middle of water have neutral buoyancy.
What will not float nor sink in water?
These objects are called with "neutral buoyancy".
What is another word to describe an object with neutral buoyancy?
It is average density.
