This organelle is the "command centre" of the cell.
What is the nucleus?
In this state of matter, the particles are tightly packed, and vibrate slightly, from side to side.
What is a solid?
Fireflies produce this type of light.
What is bioluminescent light?
Many types of sporting equipment provide good examples of this type of lever, which has a mechanical DISADVANTAGE, but provides greater speed.
What is a class III lever?
A crack, or fissure, in a glacier is referred to as this.
What is a crevasse?
This term describes the diffusion of water into or out of a cell, in order to balance the concentrations of solutes on either side of the membrane.
What is osmosis?
This term is used to describe the process of a gas becoming a liquid.
What is condensation?
This is where the optic nerve attaches to the retina.
What is a blind spot?
This is the name of the principle that pressure applied to liquid in one part of a closed system, will be applied equally to all other parts of the system.
What is Pascal's Law
This is the main force that causes Earth's tides.
What is the gravity of the Moon?
This organelle allows plant cells to maintain their shape and structure.
What is the cell wall?
This measurement is often used to determine the viscosity of a substance.
What is flow rate?
This part of the human eye performs the same function as the diaphragm in a camera.
What is the iris?
These species are tested to determine the water quality and overall health of the ecosystem.
What are bioindicator species?
The bronchioles and alveoli are important parts of this system in the human body:
What is the respiratory system?
Petroleum is separated into its parts using this method of separation.
What is fractional distillation?
This phenomenon occurs when light bends as it travels from cool air to warm air. (*hint -- on a hot day, you may see "puddles" on the street as you're driving)
What is a mirage?
What is a pneumatic device?
What is algae?
These blood vessels are hair-thin, allowing for the diffusion of oxygen and nutrients across its membrane.
What are capillaries?
This is the name of the principle that states that the weight of the water displaced by an object is equal to the buoyant force acting upon the object.
What is Archimedes' Principle?
This type of mirror creates "real" images, and also may be used when applying make-up.
What is a concave mirror?
Hydrogen fuel cells produce this as a waste product.
What is water?
This region in the ocean is where temperature rapidly declines.
What is the thermocline layer?
