Physics-Great Race

My car has only two power sources. I am not done with my car yet, but for the finishing touches I plan to add a a balloon to the top of my car to give it an extra boost. My other power source is plain old gravity. My car demonstrates all the laws of motion. The first law of motion states that an object will remain at rest until acted upon by another force. That other force can be interpreted as my balloon or gravity. At the top of the ramp my car will just start to go down due the force of gravity on it. The second part of the first law states that an object will remain in motion unless acted upon by another force. The force that slows my car down is friction. But the friction in my car will be greater because on side of my car is touching the floor which causes drag. The second law of motion states that force = mass x acceleration. The ramp will provide the ample time to accelerate, but currently I have found nothing to increase the mass. Most likely I will tape a somewhat heavy object to my car to overall increase the acceleration. My car is an example of the third law of motion. My second power source, the balloon, will be facing in the opposite direction of the car and the balloon will blow out air causing a speed boost. The third law of motion states that for every action there is an equal and opposite reaction. In this case my balloon will blow air in the other direction causing my car to go faster in the correct direction. My overall car is done, but I have to add a few adjustments and I will be done with it!

The Wolf in Sheep's Clothing

I think that the moral is to make sure that everything is in place before believing someone. The lamb thought that the wolf was a fellow sheep and in the end the fox killed him. If he had made sure that the wolf in the sheepskin was actually a sheep he might not have been killed. This is something I need to work on because as I said before I am very gullible.

The Four Oxen and the Lion

I think that the moral of the story is to stick together. If they had stuck together they wouldn't have died because the lion never bothered them when they were all together. Four heads are better than one.

The Fisher and the Little Fish

The fisherman only got one, small little fish, but he kept it knowing that if he threw it back he might not get anything. The moral of the story is, don't throw away something because it is small or useless, keep it because you might not get anything bigger or better. The fisherman might not have gotten another fish if he let the small one go so he kept it.

The Crow and the Pitcher

If you fail at first, try and try again. I believe that this the maxim of the story. The crow at first couldn't reach the water, but he innovated and came up with a brilliant idea to get the water. If he had given up at first, he would have been dead without water. It is only because that he tried again and came up a new idea did he finally succeed.

The Fox and the Goat

I think that the moral of the story is to not always trust anyone and everyone you meet because they might want to trick you and deceive you. This sheep resembles my character in a way. I always believe what people tell me and I get duped. We both will just have to learn from our mistakes... If the sheep had not trusted the fox then the sheep would be safe from harm.

Genetics Post 2

Even though I have done genetics I never knew a lot of these facts. I learned a hoard of new things that I never knew! One thing I learned was that chimps and humans ( on the genetic level) are almost exactly alike except for a few minor differences in DNA. Another important thing I learned was that there isn't a relationship between the number or chromosomes and the number of genes. From the second link I learned that our chromosomes are not one big strand because our bodies are so complex and because we have a tremendous amount of DNA in our bodies. Other organisms like bacteria keep all their DNA in one strand. They do this because they reproduce asexually meaning when they reproduce each bacteria gets half the copy of the same DNA. In the third link I found something out that added on to this concept. We have an enormous genome compared to those bacteria. Since our genome is so big we divide it all up into our 46 chromosomes. After reading the links I was really shocked. It taught me so much!
