This is the liquid transportation system of our blood.

What is plasma?

100

These are the positively charged particles and their location within an atom.

What are protons in the nucleus?

100

This is the formula for calculating speed.

What is speed = distance / time?

100

This is the name of the ray before it crosses a change in medium.

What is an incidence ray?

100

This is the difference between renewable and non-renewable.

What is renewable resources can be replenished by natural processes within the lifetime of a human being?

200

These specialized cells have no nucleus or mitochondria so that they can carry more heamoglobin.

What are red blood cells?

200

These are the negatively charged particles and their location within the atom.

What are electrons and orbit/cloud?

200

This is the formula for calculating pressure.

What is pressure = force / area?

200

This is the line that is 90 degrees or perpendicular to the change of medium or reflective surface.

What is the normal?

200

This is the difference between climate and weather.

What is weather is the moment to moment atmospheric condition, and climate is the average weather over a long period; ~30 years?

300

These specialized cells defend our bodies against pathogens and produce antibodies.

What are white blood cells?

300

These are the neutral charged particles  and their location in the atom.

What are neutrons and nucleus?
300

This is the formula for calculating concentration.

What is concentration = solute / solution (mass / volume)?

300

This is the ray that has changed speed after it has entered a different medium.

What is the refracted ray?

300

This is the effect on the atmosphere of humans burning fossil fuels.

What are increased carbon dioxide and climate change due to the greenhouse effect?

400

This is the movement of an animal's muscles in order to pull air in and push air out of the lungs.

What is breathing?

400

This is the force that holds an atom together, and how it works.

What is electrostatic force or attraction, and opposite charges attract?

400

This is the difference between dilute and concentrated.

What is dilute means a small amount of solute dissolved into the solvent, and concentrated means a large amount of solute is dissolved into the solvent?

400

This is the law of reflection AND the law of refraction.

What are "The angle of incidence is equal to the angle of reflection" and "The angle of incidence is NOT equal to the angle of refraction"?

400

This is the difference between bioaccumulation and biomagnification.

What are bioaccumulation is persistent chemicals building up in an organism over the course of its life, and biomagnification is the increase of persistent chemicals at the top of the food web?

500

This is the chemical reaction that takes place in the mitochondria AND the word formula for the reaction.

What is aerobic respiration and oxygen + glucose -> carbon dioxide + water + *energy?

500

This number tells us the quantity of protons that an atom has, and is the defining feature of the element.

What is the atomic number?

500

These are the rules for graphing.

What are pencil, straight edge, x's or +'s, label the axes, and consistent intervals? Bonus: time goes on the x-axis usually.

500

This is a good analogy for why light slows down or speeds up when it changes medium.

What are tank treads; part of the wave slows down before the rest of the wave when it hits a glass block?

500

This is the highest solubility solute when looking at a chromatogram.

What is the solute dot at the top of the chromatogram?
