Define a mole.

A mole is a unit of conversion to represent an amount equivalent to 6.22x10^23 atoms. On the periodic table, you can see the atomic mass of each element below the letter. For example, Oxygen or O has an atomic mass of 16. This number can also be used as the molar mass, meaning per 1 mole of Oxygen there would be 16 grams needed to equal 6.22x10^23 atoms.

How do you conduct 3/4? Show me using your hand movements.

Using the palm of your hands, draw a triangle shape for each downbeat. At the first beat, move your arms inward towards each other, and at the second beat move them away. At the last beat, strike upwards and then reset to your first position. Visualize the triangle motion as you go.

Active Transport differs from Passive Transport in what way?

Active Transport requires energy for particles to move against their concentration gradient, while Passive Transport allows particles to go with and towards their concentration gradient, otherwise known as diffusion.
