What are the three types of symbiotic relationships?

Parasitism, Mutualism, and Commensalism.

200

What is Viscosity?

Viscosity is a property that describes a liquids thickness or thinness. 

200

What is Density?

Density is how thick or thin a object is.

200

What is pressure?

Pressure is the force applied to an object.

200

What is a lever?

A lever is one of the 6 mechanical systems.

400

What is an example of each symbiotic relationship?

Parasitism: The Tapeworm. Mutualism: The Clownfish and the Anemone. Commensalism: Bees and Flowers.

400

What are the 5 points of the particle theory.

  1. ALL MATTER IS MADE UP OF VERY SMALL PARTICLES.

  2. ALL PARTICLES IN A PURE SUBSTANCE ARE THE SAME. DIFFERENT SUBSTANCES ARE MADE OF DIFFERENT PARTICLES.

  3. THERE IS SPACE BETWEEN THE PARTICLES.

  4. THE PARTICLES ARE ALWAYS MOVING. AS THE PARTICLES GAIN ENERGY, THEY MOVE FASTER.

  5. THE PARTICLES IN A SUBSTANCE ARE ATTRACTED TO ONE ANOTHER. THE STRENGTH O THE ATTRACTIVE FORCE DEPENDS ON THE TYPE OF PARTICLE.

400

What is Buoyancy?

The ability or tendency to float in water or air or some other fluid.

400

What is force measured in?

Force is measured in Newtons.

400

What are the parts of a lever?

The beam or lever arm, the pivotal point or the fulcrum, the load, and the effort force.

600

What is succession?

Succession is the change of a species' structure in a ecological community.

600

What is a fluid?

A substance that has no fixed shape.

600

What is a buoyant force?

A buoyant force is the upward force that affects objects that are submerged or floating in water.
600

How do you calculate pressure?

Pressure = Force divided by area or F/A

600

What are the 3 classes of levers and whats in them?

The 1st class lever has a fulcrum in the middle a load on one side and the effort force on the other. In the second class lever the load is located between the effort force and the fulcrum. The 3rd class lever has the fulcrum at one end and the effort force is between the fulcrum and the load.

800

What are a consumers, decomposers, and producers?

A consumer is a living thing that can't make its own food, a decomposer is a living thing that gets it energy by breaking down dead or decomposed things, and a producer is a living thing that makes its own energy.

800

What is condensation?

It is the state of a gas becoming a solid.


800

How do you calculate density?

Density is calculated with Mass divided by Volume, or D= M/V

800

What is compressibility?

Compressibility is the ability to be squeezed into a smaller volume.

800

How do you calculate Mechanical Advantage ( MA )?

What is load force divided by effort force or FL/ FE

1000

What is a food pyramid used for?

A food pyramid is used to show the biomass that each species needs and produces.

1000

What are the 6 changing states of matter?

Condensation, sublimation, evaporation, deposition, freezing, and melting.

1000

What is the Density of the equation. A block of aluminium has a volume of 15 mL and weighs 40.5g, what is the Density.

THe density is 2.7g/cm3

1000

What is the pressure of the equation. A Elephant steps on the ground and the force is 5000N and the area of the step is 0.5m2

The pressure is 20,000 pa or 20kPa.

1000

What is the Mechanical Advantage of this equation 5600N/800N?

What is  MA= 7
