Cell, Genetics, Evolution,

This is stem class, Science, Technology, Engineering, Math ( My teacher only teach Science). Anyway, I learn a lot in is round, I have learn about Cell, Genetics, Evolution and etc. let talk about cell, The concept idea of cell is it build up you, in you there are million cell. The four main part of cell is Cell membrane, DNA,  Cytoplasm, Ribosome.  If you really want to know deeper about it I will show you Here, Cell structure, Cell function, Cell Division.

Ok let see what is Genetics, Genetics is a code who run inside you, also inside your cell. Genetics also can transfer, like GMO and etc. Link.

Now well come to Evolution, Evolution is when an organism change to a difference organism. How do we know Evolution, we learn evolution from fossil, fossil is what remain from an organism that live early before us.

Newtons Law

I learned about Newtons Law.  1. Every object moves in a straight line unless acted upon by a force. 2. The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass. 3. For every action, there is an equal and opposite reaction. 

What I learn is that, his law is obvious if you really thing about, let’s me explain about the first law, if there is nothing to stop you, do you think you will be stop, the answer is no, so if you throw a ball in a frictionless environment, the ball will fly in a straight line forever.  The second law, if you are heavy, you are harder to move than the person that are lighter than you. The third law is just second law but it say for every action there is an equal and opposite reaction, so it’s like this if you are 70 kilo, and your friend are 100 kilo, if you 2 run into each other, you will knock back, and you ask why did you said there will be an equal and opposite reaction, the answer is that because you are lighter than your friend, so the force that he felts is the same as you felt, but because he is heavier he moves just a little.
