Trust

Note: this is kind of a choose your own adventure.

In WW1(World War 1), peace broke out. It was Christmas, British and German soldiers left the trenches. They gathered to exchange gifts and play games. Why even in peace time, do friends become foes. And why even in wartime, do foes become friends. Perhaps game theory can explain it all! Here is the game: you want the most coins, and you have a opponent who wants coins too, you can either cheat, or cooperate. if both cheat, no one gets anything. If both cooperate, both get +2 coins, if one cooperates and other cheats, the one who cooperates get -1 coin and the person who  cheats gets +3 coins. Now your opponent cheats, do you CHEAT or COOPERATE?

You cheated: Exactly, if you cheat, you don't lose anything. If you cooperate, you lose a coin!

You cooperated: Bad idea, you're gonna lose a coin, if you just did the opposite, you wouldn't lose the coin.

Now the other player cooperates. What do you do?

You cheated: Mean, and correct. You got +3 coins and the alternative would give you +2 coins.

You cooperated: Seems correct... except it's not! You got only +2 coins but the alternative would give +3 coins.

Lesson: Trust is nice, but it lets other people take advantage of you. Be careful!

How your body defeats the virus

 In order to see how the cells defeat the virus, we need to know what a cell is! So, what's a cell?

That is my best representation of a cell. The outside is made of a thick flexible layer of cell membrane. The cell membrane itself is made of fats and proteins, it protects the inner components of a cell. You probably noticed a red circle around some parts, what are they? They are projections. It helps bind to nutrients, adhere to neighbors, and makes it semipermeable.

It will not let bad things in, right? But the virus is sneaky and pretends to be a friend by attaching to a projection on the cell membrane. The cell carries it through the membrane and inside. The cell recognizes it's mistake and special enzymes chop the virus to pieces, it waves a piece of the virus around to warn other cells!

 A cell sees the warning and has a plan, it needs to make antibodies. It goes to the nucleus to get DNA. What is a DNA or antibody? DNA is the blueprint telling our cells how to make everything and antibodies are proteins that attack and kill the invading virus, get used to hearing the word antibody. Anyways, in the nucleus, the enzymes look for antibody DNA and copy it to make messenger RNA

The enzymes carries the RNA to a ribosome, it takes RNA and amino acids to create antibodies. Then the antibody needs to leave the cell, they head to the Golgi apparatus and get a bubble around them. The bubble is made of the same thing the cell membrane is made of. Packed for delivery, the antibody goes to the cell membrane, the Golgi apparatus gives it instructions. It's bubble fuses to the cell membrane and the cell ejects the antibody. The leftover bubble is broken down by lysosomes and recycled over and over again.

Where did the cell get the energy to do this? It got it from a mitochondria that fuses oxygen and electrons to create water, it also creates ATP in the process. ATP is a high energy molecule. FACTS: every living thing is made of cells, none of my drawings are probably what they actually look, and there can be as many as 10 million ribosomes PER HUMAN CELL studded like a ribbon like structure called a endoplasmic reticulum. All parts need to be functional to keep you alive
