This quantity is basically another form of speed. It is very similar to speed, except that it includes a direction (or vector) . 
What is velocity? 
300
These are tiny cell organelles that are responsible for producing proteins.
What are ribosomes?

This function acts like a bracket.
It makes all the values in it positive. For example -6 becomes +6. If plotted on a graph paper, a V-shaped graph would be formed.
It is also known as an absolute value. 
What is a modulus

What is neutralization?
500
This nutrient is made up of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur.
What are proteins?
500
A measure or calculation of the concentration of a certain substance in a liquid.
What is titration?

With this, I can expand (a+b)n. Where n is any whole number.
This theorem governs all brackets that are squared and need to be expanded out.
(a+b)2 will then be equal to (a2+ b2 + 2ab)
What is the binomial theorem?
500
With this skill, I can notice that decreasing the base surface area of an object causes it to become unstable.
What does it meant by relating cause and effect?
