Lung Cancer 3

... but with technology and research that is no longer always the case. What is Cancer? Cancer is when abnormal cells in an organ start growing and increasing in an uncontrolled manner. Because the cells are dividing at a rate excess of normal division the cells form a tumour. The crowded cells fail to stop dividing until they push everything out of place. If the tumour is benign it will enlarge only at the site where it began. However cancerous tumours can invade and destroy. One of the reasons that cancer needs to be caught early is bec ...

Uranium

... in the oceans but we do not have the technology to mine it at a cheap cost. Chapter 2 Mining When uranium is extracted, pitchblende is broken up and mixed with sulfuric and nitric acids. It then dissolves into uranyl sulfate. With the addition of sodium hydroxide, uranium is precipitated as sodium diuranate which is known as the yellow oxide of uranium. To get uranium from carnotite, the ore must be finely ground and treated with a hot solution of caustic and potash to dissolve out the uranium, radium, and vanadium. And after the sandy ...

Bang, The Life Cycle Begins

... back to a single, inconceivably dense point concluding the life of the universe. You would think of this as the end, but only an explosion is needed to wake up and give life to a new universe. Therefore, trapped forever in the cycle of rebirth. As humans we also travel through a cycle of rebirth according to the Hindu religion.

Is There Evidence That Homosexuality Is Biologically Determined?

... the article written by LeVay and Hamer, the evidence presented clarifies where they stand. Among the list of evidence provided is that the sexual orientation of a male is influenced by heredity due to the fact that “it directly examines the genetic information, DNA.” Furthermore, if there is a gene that influences an individual's sexual orientation, there is a great possibility of that trait being passed down from generation to generation. Experiments conducted led to the possible conclusion that the region Xq28 carries ...

Genetic Engeneering

... in the long run it could turn out a disaster, causing pollution, killing crops, animals or even us, is it such a good idea to play with gods creations? Only you could decide. A lot of scientists believe that genetic engineering is a revolutionary brake through. With the use of gene technology it is possible to create a ‘perfect’ organism. Useful characteristics can be transferred from one species to another, this includes animals with plants and vice a versa. As a result it is possible to make foods with high resistance to wheth ...

The Periodic Table

... change properties gradually through the entire list from hydrogen to calcium, in keeping with gradual increase in atomic weights. Rather, the properties change gradually through a certain number of elements, called a "period" of elements. Then they repeat, through the next period. To express this, Mendeleev stated the periodic law: The properties of the elements are periodic functions of the atomic weights. provides an easy way to show the division of the elements into acid-forming and base-forming types. Those on the left are base-forming; ...

The Comparative Abundance Of The Elements

... a thin layer of gases, 95% of these gases are within the first 20km of the earth's surface. Of the 17 elements that make up 99.5%, the most abundant of these are Oxygen 49.2%, Silicon 25%, and Aluminum 7.5%. Then the next most abundant elements are Iron 4.7%, Calcium 3.4%, Sodium 2.6%, Potassium 2.4%, Magnesium 1.9%, Hydrogen 0.9%, titanium 0.6%, Chlorine 0.2%, Phosphorus Manganese and Carbon are all 0.1%, Sulfur 0.05% Barium 0.04%, Nitrogen 0.03% and the rest of the elements on the periodic table take up about 0.5%. The elements of ...

Do Science And Technology Provide A Solid Base For Technocra

... Conclusively the objective of the group is either initially or ultimately the result of compromise being either very limited or very general in scope. This explains the ineffectiveness of the emotional approach and the political generality does not adequately define the project. The end result is the making of a mountain out of a molehill where the emphasis is on the exaggeration and reiteration of minor differences while ignoring what they have in common. Technocracy partakes one single element in that it is dependent on the voluntary as ...

Rutherford

... his famous "gold foil" experiment. He directed alpha particles at a thin sheet of gold foil and expected the particles to simply travel straight through the foil. However, he obtained very different results. Although many of the particles did in fact go straight through the foil, some of them were deflected at large angles. Rutherford concluded that the deflections of the alpha particles were caused by a center of positive charge that contained most of the atom's mass (the nucleus). He also explained that the particles that ...

Evolution Of Immunity And The Invertebrates

... to understand that phagocytosis played a much broader role, it was a fundamental mechanism of protection in the animal kingdom. Metchnikoff's further studies showed that the host defense system of all animals today were present millions of years before when hey were just beginning to evolve. His studies opened up the new field of comparative immunology. Comparative immunologists studied the immune defenses of past and current creatures. They gained further insight into how immunity works. The most basic requirement of an immune system is to ...

The third rule is that you should only interact with your partner and the teacher. This will prevent distraction from your set experiment. The fourth rule is that you should not leave your experiment unattended whether you think it is dangerous or not. This rule is completely self explanatory for safety purposes. The fifth rule is to be extremely careful with e ...
