Learn how to solve problems involving Boyle's law. Boyle's law states that as pressure increases then volume decreases and pressure decreases volume increases.
I use the Boyle's law formula Pressure x Volume = K
Example problem:
3.00 L of a gas is at 740.0 mmHg pressure. What is its volume at standard pressure?

A gas occupies 12.3 liters at a pressure of 40.0 mm Hg. What is the volume when the pressure is increased to 60.0 mm Hg?

The sodium-potassium pump is a type of active transport that moves 3 sodium ions into the cell and 2 potassium ions out of the cell. I cover why the pump is needed and provides an overview of this type of active transport cells use to move important objects into and out of the cell.
ATP is used to change the shape of the carrier protein allowing the sodium and potassium to move across te cell membrane.

Plant root structure explained.
The root of a plant helps anchor the plant and absorb water and nutrients from the soil.
There are two main types, a taproo nd a fibrous root.

In this video, I show you how to find the exact square root of a number using a factor tree.
A factor tree allows you to find the prime numbers of a number.
Once you know the prime numbers then you can easily find the square root.
In this video, I find the,
The square root 50
The square root of 9
The square root of 25
The square root of 12

Our blood helps keep us alive.
Your blood makes up around 7% of your body weight
This equals between 1 and 1 and a half gallons 4.5 to 5.5 liters
Your blood is considered a connective tissue.

Our blood has many important functions.
Here is a list of some of the major jobs
Transports oxygen to each cell.
Removes waste material like carbon dioxide.
Helps regulate your temperature and ph levels.
Fights disease and helps the immune system do its job.
Blood transports nutrients, such as sugars, fats and proteins, amino acids,
Along with hormones which are your chemical messages of the endocrine system.
It is made up of red blood cells, white blood cells, platelets, and plasma.

Learn how to write an equation f a line using y = mx+ b and this will allow you to write the equation slope intercept form.

Diffraction is the bending of light as it passes around the edge of an object or through a slit.
Refraction is the bending of a wave when it enters a medium where its speed is different.
When a wave passes through a slit it spreads out in waves as it passes through the slit.

The first stage of mitosis called prophase

Saprotroph and detrivore are important decomposers that help recycle organic matter.
Saprotrophs include bacteria and fungi. These biotic factors release enzymes that break down the detritus.
Detritivores must ingest the decaying matter before decomposing it.
Both of these decomposers help recycle nutrients in an ecosystem.

Learn what the square root of 5 is, plus how to simplify the square root and the decimal value. I also review how to estimate the square root of 5. I like to use a factor tree when simplifying a radical.
