**What is Evolution** Simple answer for this question, Evolution is a transform from one character to another character and the specie can do evolution's process because they need a fit size, body and color to get use to the background or the place where they move or change naturally. media type="youtube" key="GhHOjC4oxh8" width="560" height="315" align="center"

**History of evolution?** In history of biology about evolution, it has many scientist but Charles Darwin is a special scientist about that. Charles Darwin was born in 12 February 1809 – 19 April 1882 and was an English naturalist and geologist. He was a youngest son of wealthy family. His family was a doctor a long time and his father wanted him to follow Family's job. But when he was in   Edinburgh University   , he didn't concentrate his study instead he was looking for creatures in  ocean. Moved to Cambridge University, they encouraged him study and learn what he wanted to. Five years, he learned and traveled everywhere, he began to famous with his   travel diary. It announced about a fossil and collect species to prove that it had something had changed. And it was called "evolution". he contributed his evolution theory and released a book talked about his theory.

**why do creature change?** It has five reason to make creature develop: Adaption (because of environment make creatures change to suit with habit), co-evolution ( changing because of another creatures), speciation( same creature but in them have something different) **what is the reason?** Following in biology, the reason creature can change is: mutation ( the bases of gene are changing or part of gene change), sex and recombination, heredity( same gene in offspring and changing with contrast trait and   recessive trait    ) **information!** mutation: []

evolution: [] heredity: [] __genetic__ what's it genetic? it's show up the offspring has the inheritance  trait from the parent by generation to generation video: [] history/ background talk about genetic, we can't talk about Gregor Johann Mendel. Way back to 1800s, he was Austrian and spent two years for studying in the University of Vienna. when he did the experiment to the scientific method. he began to breed pea plants when he was working church and he began to learned about the inheritance. videp:https://www.youtube.com/watch?v=HWbhXcm43lI the inheritance. The inheritance is kinda like copy some traits of parents to their children. And Mendel figured it out when he grown the pea plants to study for his projects. the offspring pea plants has some traits look like their parents. He figured out that the traits are divided to two type: Mendel saw in the first generation the offspring show off little trait from one of parents and the second generation the another offspring show off the other traits, which one of parents has but don't show off on the first generation. source: http://en.wikipedia.org/wiki/Inheritance
 * Dominance: it is called a "power" traits always show off on the offspring.
 * Recessive: it is called a "weak" traits always show when they just go along



how can it happen? Mendel studied and knew the reason the trait can follow to another generation:
 * when the sperm has gene from dad and the egg has gene from mom, they make to offspring. their gen will cross together and keep growing.



video: https://www.youtube.com/watch?v=UMSujz-Rup4 what did he do when he figured out everything, he began to study how can predict. And i think about using a Punnett square and he did. He can predict a next generation but he just knew not exactly, he just can predict how many percent can be happened for off spring.



the traits can be homozygous ( meaning it just has dominance or recessive trait) or heterozygous ( meaning it mix together and dominance always to show off on the offspring). And a gene in result is called genotyoe and show off on the offspring is called phenotype. some result of the crossing some result happen when we can see a real life. Because some issue like they get same dominance so they have some different result: some source: http://www.nhs.uk/Conditions/Genetics/Pages/Facts.aspx [] [] http://ulf.org/genetic-inheritance Body Systems **What is body system?** Body system is the lines connect everywhere in the part of body to the brain by nerve. And we can call that is nervous system. http://en.wikipedia.org/wiki/Nervous_system#Neurons Nervous system has a responsibility to reply the "message" from the environment effect to body. For instance, when you leg step on nail or something sharp, it wil be bent. the body can reply the message by the neuron carry the massage from the place of body where environment effect. **The structure and how is working of neuron?** Dendrites: it can be called as "the enter of neuron". it has responsibility to take the massage from the outside to neuron or from another neuron transmit. Cell body: this one help to nourish the cell Nucleus: the center of the Neuron. Axon: the long connection chain from dendrites to Axon terminals. it help the cell carry the information go through the cell. Myelin Sheath: this one help the information can't go outside the cell. Schwann's cell: Axon terminal: it help for information go out to another neuron and go to the brain. http://en.wikipedia.org/wiki/Neuron when the information go to axon terminals they will impulse the ionize go to the terminal and take place to receptor to impusle the information. http://www.brainfacts.org/brain-basics/neuroanatomy/articles/2012/the-neuron/
 * codominance: it can be called mixing traits together and show off on the offspring
 * Incomplete: it is same codominance but they have a diference ( such as: color, shape,....)
 * What does the nervous system do?**
 * How can the information from outside can transmit to from another neuron to another neuron?**

https://www.youtube.com/watch?v=LT3VKAr4roo **Brain** It's the most important part in body of human. It help person can think and learn. Also, it's a part for neuron give the information into and tackle the information to reply the message back. https://www.youtube.com/watch?v=9UukcdU258A **how can the information can run so fast onto the neuron?** In the Axon, the neutrontransmiter or called as information will go through the axon really fast. But in order to let process happen, they need to help the electrical impulse. the electrical ion consist of potasssium(K+), chloride(Cl-) and sodium(Na+), they change the position in and out the each node. But inside the node is minus and outside is plus, so they are changed by concertration. for instance, when the Na+ outside has much more than inside they will move in via potassium-sodium potential.
