What is the cell membrane?

100

The study of the external features of an organism.

 

What is morphology?

100

A diagram which show the dry mass of consumers and producers in a habitat.

What is the pyramid of mass?

100

Occurs when two population of the same species can no longer successfully breed together.

What is reproductive isolation?

200

A substance that dissolves in a solute

What is a solvent?

200

The measure of the mass of one unit volume of a certain substance. 


What is density?

200

A type of rock that was formed as a result of intense heat and pressure in the Earth's crust. 


What are metamorphic rocks?

200

A section of Chemistry that involves the calculation of the molar mass, mole and mass of the products and reactants of a certain reaction. 

Hint: Chemical calculations


What is stoichiometry?

200

This states that the product of pressure and volume is equal to the product of the number of moles, a constant, and temperature.

Pressure x volume= moles x constant x temperature

constant=8.3145 l kPa/K mol

What is the ideal gas law?

300

This is how chemist arranged all the elements.

What is the periodic table?

300

A deficiency disease suffered by those who are lacking Vitamin C.

What is scurvy?

300

Two sets of lines that will never meet. 


What are parallel lines?

300

An element, given by the electronic configuration of 1s2 2s2 2p3

Hint: Sum up the indexes to get the proton no. 

This element forms 78% of Earth's atmosphere and is among a group of elements, known as pnictogens.  

What is nitrogen?

300

This can be used to find probability in complex circumstances, specifically when sets of condition related to that event is provided.

What is bayes' theorem?

400

An organ that produces bile to neutralise the acidity of pepsin from the stomach.

What is the gall bladder?

400

The angle at which a light ray approaches a certain medium.

What is the angle of incidence? 


400

The study of the relationship between angles and length in  triangles.

What is trigonometry?

400

This states the relationship between potential difference, current and resistance.

What is Ohm's law?

400

This states that the speed of liquid flowing out of an orifice is the same as the speed of an object when it hits the ground from the water level at any point in time.

What is Torricelli's theorem?

500

a pair of equations containing two variables that must be solved.

What is simultaneous equation?

500

This measure the degree to which metals react with other substance.

What is reactivity?

500

This the degree of an object's movement relative to their mass.

Obtained by finding the product of mass and velocity.

What is momentum?


500

This is the study of shapes in graphs (Cartesian), often governed by different equations.

What is coordinate geometry?

500

This is the section of the genes in the lagging stand of the DNA created by RNA primase followed by DNA polymerase copying in the 5'--->3' opposite direction.

What are okazaki fragments?
