... the less a animal used its body parts the smaller or weaker it became. He thought that these traits became hereditary. Later scientist disproved this theory when more was learned more about genes and how they work. 50 years later Darwin came up with a theory that most scientist believe it to this day. this is called the theory of evolution. His book was called “The Origin of Specie.” Alfred R. Wallace, came out with a theory that was almost identical to Darwin’s theory. Darwin’s theory was much more developed and better known. For example Darwin pointed out that farmers would t ...

... cheetah is only 44-53 inches long. On the TV they always seem bigger somehow. And the tail is about 26-33 inches long! Their average weight is 86-143 pounds, surprisingly light for such a powerful animal. It’s low weight, it seems, is what allows it have it’s high top speed of sixty miles per hour. It is regarded as one the fastest hunters in the world and of course, the fastest land animal in existence. I also found that it’s habitat is in the grassy plains of Africa. This is definitely a great place for it to hide based on it’s coat color. It is because of this combination of tall grass and ca ...

... in our solar system. Much of the Martian surface is rough and cratered, but expansive flat plains and smooth hills can also be found. Unlike any other planet, there is a striking difference between the northern and southern hemispheres of Mars; one is extremely rough and old while the other is young and relatively smooth. The southern hemisphere is strewn with ancient craters of all sizes and is also elevated by a several kilometers creating a visible boundary. On the opposite end the northern hemisphere consists of a wider variety of geological features, but is obviously smoother and much younger. There are ...

... illness or disease can cause persistent anxiety. Treatment of the illness or disease will stop the anxiety. Anxiety illnesses affect more than 23 million Americans with about 10 million Americans suffering from the most common, general anxiety disorder . (Harvard, 1). Common are panic attacks (panic disorder), phobias, and general anxiety disorder (GAD). Panic attacks can begin with a feeling of intense terror followed by physical symptoms of anxiety. A panic attack is characterized by unpredictable attacks of severe anxiety with symptoms not related to any particular situation. (Hale, 1886). The person exp ...

... using helium that most people are not aware of. The public needs to be aware and understand it is not for inhaling. Some teenagers think inhaling helium at parties is fun. But what they don't know it is also fatel. An aspect of inhaling is a person may lose consciousness due to asphyxia (oxygen deprivation). During the exchange of gases in the normal breathing process, the blood stream absorbs oxygen from air in the lungs, while carbon dioxide passes from the blood to the air. When you hold your breath, the exchange of gases slows, as "stale" air in the lungs is no longer replaced by "fresh" air. Oxygen is ...

... Prior to 1986, the A and B chains of the insulin molecule were produced by separate fermentations (growth of the genetically altered Escherichia coli under controlled conditions). The chains were purified and later combined by chemical techniques to produce insulin structurally and chemically identical to pancreatic human insulin. (Hyde, 1984) As of 1986, human insulin began to be produced by a process which involves the enzymatic conversion of human insulin's biosynthetic precursor, human proinsulin. The genetic coding for human proinsulin is inserted into the special E. coli bacteria which are then grown i ...

... of an isolated system is the table and the balls, and the law then implies that the total momentum of the balls just before they collide is the total momentum just after the collision. Therefore if the masses of two colliding objects are known, the velocity and the velocity of the other before the collision, you can calculate the final velocity of this second object after it has collided. To obtain an exact answer however, we must find out what type of collision takes place, whether it is elastic or not elastic. The type of collision is characterized by what is called the coefficient of restitution. Thi ...

... of this substance was a thick, white liquid that had a horrible odor. These observations led me to my conclusion that substance B is spoiled milk. Test-tube C: Test-tube C had ammonia in it. The substance reacted to red litmus paper, and it had no effect on blue litmus paper. Phenolphthalein turned a hot pink color very quickly, and the pH value was about 11.5. The substance was clear and had a strong odor to it. These results led me to my conclusion that substance C is ammonia. Test-tube D: Test-tube D contained lemonade. The substance reacted to blue litmus paper, and red litmus underwent no changes. It had n ...

... In modern times the slow rotation of the Sun has been explained as resulting from the deceleration of its angular motion through its magnetic interaction with the outflowing solar wind, so that this feature should not have been considered a constraint on theories of the origin of the solar system. The many theories concerning the origin of the solar system that have been advanced during the last three centuries can be classified as either dualistic or monistic. A common feature of dualistic theories is that another star once passed close to the Sun, and tidal perturbations between the two stars drew out f ...

... birth. There have been no significant differences found to exist in the *age*-length relationships of C. maximus populations World-Wide. Although all Basking sharks are large, the females tend to be quite a bit bigger than the males, which is probably because they have to carry a whole other organism within (Harman, 1996, 21). Basking sharks have, at some point in time, also been known as the elephant shark, the Bone shark, sailfish shark, and sunfish. The reason this shark is occasionally referred to as the Bone shark, is because when they die, they sink (their density is great ...
