... a well balanced diet must include Vitamins. Vitamins are chemical compounds that have no energy value, but instead act as catalysts inside the body. One variety of vitamins is the Vitamin A. This group includes retinol and carotene. Carotene is a yellow pigment found in vegetables such as carrots. A diet that is lacking in Vitamin A depreciates a person’s ability to see in the dark. Which is where the saying that carrots will make you see better is derived from. Carrots were the vegetables chosen to be tested in this experiment. This experiment was designed to test if the processing of a carrot produces gas. In t ...

... the offspring of these humans were to be produced through a wonderful and special moment between man and woman. Science has no part in producing a child and no one, no matter how intelligent, has any right to tamper with God's creations. It has been almost a hundred years since the first clone was ever created. In the year 1902, a German embryologist by the name of Hans Spermann used a strand of hair as a noose to split apart cells of a two-celled salamander embryo, and obtained a normal salamander from each cell. Thirty-six years later, Spermann used nuclear transportation to create a clone. He took the nucleus, ...

... salamanders as early as the 1950s. In 1996, a group of Scottish scientists used the procedure to clone a sheep. This event marked the first time a mammal had been cloned in this way ("Clone"). The scientist who started cloning is Ian Wilmut (who led the group) (Recer). He cloned Dolly using the nucleus from the cell of its mother, and it had an exact genetic replica of its mother. This spurred arguments about cloning humans (Recer). After Wilmut hinted he may be repeating his experiment to silence the critics (Recer). Wilmut does not have the courage to repeat his experiment, also that the government will never allo ...

... the natural ecosystems of the earth and how people can help to revive them. Louise Miller once said that,". . . the ecologist is the one that brings together the study of all natural systems- earth, air, water, plants, and animals. Connections between living organisms and effects of their interactions are ecologists' concerns. . . . .The balance of nature, wherever it occurs, is what you will investigate and analyze"(17). Since a career as an ecologist is usually long term, there are certain characteristics a person should have in order to maintain a successful career. One of these characteristics that is the ...

... Burning fossil fuels has other downfalls, too. All the burning that is required to turn the turbines releases much sulfur, nitrogen gases, and other pollutants into the atmosphere. The cleanest, cheapest, and least polluting power plant of the two types is the hydroelectric power plant. The main reason most countries use thermal versus the hydroelectric is because their countries don't have enough concentrated water to create enough energy to generate electricity. (World Book vol. 14, 586) plants generate only about eleven percent of the world's electricity. There are around 316 plants in the world that create ...

... We looked to see if we could find anything germinating. We quickly noticed something that appeared like an air bubble squirting out something green. This was our fern spore which was germinating. Next, we removed a few of the germinating spores from the petri dish and put them under a compound microscope scope. We found the spore wall and observed how the developing gametophyte had broken through the wall, as instructed by our lab manuals. One could also identify the chloroplasts with in the cell. We then put up our dishes for another week. The third week of our fern lab we identified the difference between ...

... the Sumerians. The Greeks gave Mercury two names: Apollo for its apparition as a morning star, and Hermes as an evening star. Greek astronomers knew, however, that the two names referred to the same body. Since Mercury is a smaller planet, extremely close to the sun, and has no substantial atmosphere, it has the greatest temperature range of any planet or natural satellite in our solar system. The surface temperature on the side of Mercury closest to the Sun reaches 427 degrees Celsius, a temperature hot enough to melt tin. On the side facing away from the Sun, or the night side, the temperature drops to -183 de ...

... inertia. Let's say that someone parks a car on a flat road and forgets to put the vehicle into park. The car should stay in that spot. This state of being is called inertia. All of a sudden the wind picks up or some kid crashes into the car with a bike. Both the wind and the kid's bike crashing into the bike are unbalanced forces. The car should start to move. The car might accelerate to two miles per hour. Now we would all assume that the car would come to a stop sometime. We assume this because it is true. It is true because there is friction between the tires and the road. The car now has inertia in ...

... Hemisphere), the cyclone gradually picks up speed. Driven by the fast winds, the Cyclone can move at up to 50km/h. While all this is happening a distinct "eye" is forming in the centre of the Cyclone. This "eye" unlike the rest of the Cyclone is completely calm and is not windy at all. Cyclone Tracy was the most destructive cyclone recorded to hit Australia since white settlement in 1788 (the Bathurst Bay killed 300 people but didn't reach land). Cyclone Tracy hit the coastal city of Darwin on Christmas Day 1974. Although people had warning on New Year's Day about Cyclone Tracy, they were busy preparing for Ch ...

... the sun hits the earth's atmosphere, it hits and divides the oxygen molecule (O2). Each molecule then attaches with other oxygen molecules to form O3. O3 is ozone. So when ozone is formed, harmful rays from the sun are absorbed. The O3 molecule is very reactive and it bonds easily with other molecules it the atmosphere. When and oxygen atom from the ozone reacts with a chloride ion from chlorine monoxide, the ozone molecule is destroyed. So chlorine monoxide is an ozone destroyer. There is always a certain amount of chlorine monoxide in the atmosphere. It is important to remember that ozone is constantly being c ...
