Learns learn why vertical lines have undefined slopes. Slope is defined as rise over run. When you have a vertical line you end up with a zero as a denominator which causes an undefined slope.

Detrivores are heterotrophs that feed on decaying organic matter in an ecosystem. Common examples of detrivores include worms and millipedes. Without decomposers and detrivores, the earth would be covered up with dead organisms.

X-linked inheritance involves traits found on the x chromosome.
Humans have 23 pairs of chromosomes. Females inherit two x chromosomes and males inherit an x and y chromosome.
The x chromosome has many more genes than the y chromosome. As a result, you get what is called an x-link trait.
In this video, I show a Punnet square of an x-link chromosome and why males may inherit the trait more often than females.

Cell basics- Lysomes
What are the properties of a lysosome?
Lysosomes are organelles found inside plant and animal cells, but not in bacteria cells.
Updated Version
https://youtu.be/jvfDdZtD5SQ

They are important because lysosomes help break down old cell parts and and digest materials brought into the cell. They might be used to digest food or break down the cell when it dies.
Lysosomes have a single membrane and are filled with digestive enzymes.
A lysosome is created at the Golgi apparatus.
The proteins of the lysosome are created at the rough ER and are packed in a vesicle that is transported to the golgi apparatus. The golgi apparatus uses these proteins to make digestive enzymes and creates a vesicle that pinches off.
This vesicle is a lysosome
Lysosomes are found in the cytoplasm.
When materials are brought into the cell lysosomes can attach to these objects and begin to break them down.
Lysosomes will also break down other organelles like mitochondria if the cell does not have any food or the mitochondria is working improperly.
Lysomes will even digest bacteria that enters the cell.

Igneous rocks are created when molten rock cools either on the earth's surface or slowly inside the earth.

Rocks that are created from magma that reaches the surface are called intrusive or volcanic igneous rocks.
Rocks that are created inside the earth are called plutonic or intrusive rocks.

What is a ribosome?

When you look at pictures of cells, you can see tiny dots on the ER and in the cytoplasm.

These dots are ribosomes, but why are they important to the cell?
Ribosomes are small protein factories found in cells.
They are located in the cytoplasm and on the rough ER.
Ribosomes look like small dots on the ER and in the cytoplasm.
Ribosomes are found in plant,animal, and bacterial cells.

How does a ribosome make a protein?
mRNA that has been created at the nucleus and travels to the ribosome.
tRNA travels to the mRNA and reads it in triplets called codons.
The tRNA has an amino acid on one end.
The tRNA reads the mRNA and strings the amino acids together in the correct order.

Why is protein important?
Protein is used for many functions in the cell.
Proteins are used as building blocks and structure suppor. Your skin, and tendons are made up of protein.
Some proteins help with digestion.
Proteins help with muscle contraction, and carry oxygen around the body.
These tiny organelles play a very important in helping organisms stay alive.

What happens in prophase?
Cell Division Crossword Puzzle
http://www.moomoomath.com/cell....-division-crossword-

Prophase is the first stage of mitosis.
During prophase, the chromosomes first begin to appear.
Next, the nuclear membrane begins to break down, and the centrioles produce mitotic spindle fibers.

Use a factor tree to find the LCM of 24 and 36 plus the greatest common factor of 24 and 36

In this video I will talk about three types of circulation found in the human body. lymphatic circulation and two types of blood circulation. Pulmonary circulation and systemic circulation.
Let’s look at blood circulation first.
Your blood is responsible for carrying oxygen, waste, sugar, and other important items throughout your body.
In order to carry oxygen and eliminate carbon dioxide it must travel to the lungs. Pulmonary circulation is when blood travels to the lungs and back. Blood enters the right atrium from the superior and inferior vena cava. It travels to the right ventricle and into the lungs through the pulmonary arteries. In the lungs oxygen is exchanged for carbon dioxide at tiny air sacs called alveoli and then returns to the heart through the pulmonary veins.
Up next is systemic circulation which is circulation throughout the body. As blood returns from the lungs it enters the left atrium then travels to the right ventricle then passes out the aorta and into the rest of the body. This circulation is called systemic circulation.
Three types of vessels are used for blood circulation.
An artery is a blood vessel that takes blood away from the heart to all parts of the body (tissues, lungs, etc). Most arteries carry oxygenated blood Arteries are usually shown as red vessels.
Veins are blood vessels that carry blood toward the heart. Most veins carry deoxygenated blood from the tissues back to the heart both of which carry oxygenated blood to the heart. Veins are usually shown as blood.
Capillaries are tiny vessels that connect arteries and veins.

The third type of circulation is called lymphatic circulation.
The lymphatic system absorbs and transports lymph. Lymph is a clear fluid that is a result of plasma leaking out of capillaries.As plasma moves out of capillaries, some of it is not reabsorbed. You lose around three liters of the plasma a day. The lymphatic system reabsorbs lose fluid.
If you look at this cross section of a tissue you can notice how the lymphatic vessel is located near the vein.
Once this plasma that has leaked out of capillaries and enters lymphatic vessels it is called lymph
Lymph also includes protein and cellular debris which are too large to be collected by veins and capillaries.

The lymphatic vessels have smooth muscle and valves that help move the lymph throughout your body.

Two is not a perfect square Which means there is not a whole number multiplied by itself that equals 2. For example, the square root of 4 is 2 because 2 x 2 = 4

The square root of 2 is an irrational number.
Here it is written out 65 places,
1.41421356237309504880168872420969807856967187537694807317667973799,
but most of the time you should be ok using 1.4142.
The square root two can be represented as a fraction as 99/70
The square root of 2 is equal to the length of the hypotenuse of an isosceles right triangle with legs of length 1.

Learn to solve algebra word problems.
This problem involves a two-step equation in which you have to solve for your variable by moving the numbers to the right of the equal sign.

A relationship between two species of plants or animals in which one benefits at the expense of the other, many times the parasite lives in or on the host and may even cause the host to die.

An updated version of graphing inequalities ( no music )
https://www.youtube.com/edit?o=U&video_id=HDq7l7CnN-A

In this video, you will learn how to basics for graphing inequalities on a number line.
Inequalities show that two expressions are not equal.
For example, a number can be greater than, greater than less than, less than, less than, less than or equal to, and not equal to.
When graphing the inequality on a number line you can use an open graph that does not include the number, and closed in which includes the number.
