Transmission Of Aids

... Although HIV can be found in body substances such as saliva, tears and urine - the quantities in which they are found in are so low that they are relatively harmless. WHO ARE AT RISK OF GETTING AIDS? Over 500 Singaporeans have been tested positive for HIV (up to late- 1996), however, this is probably only the tip of the iceberg as there are many others who are infected but do not know that they are. In the 1980s, the majority of infections in Singapore were homosexual or bisexual men; but now there are many infections seen among heterosexual ...

Buoyant Forces

... it's weight, which was .98 newtons. Then next step was to measure the apparent weight of the cylinder when it is completely submerged in a bath of water using the formula Wa=ma*g , this was found to be 88.5grams. Knowing these two numbers, the bouyant force that the water places on the object can be calculated using the formula Fb=W-Wa , Wa=.8673n W=.98n Fb=.1127n Part 2 of this lab consisted of weighing an empty cup, which was 44grams. And then filling another cup up to a certain point the if any more water was added, it would s ...

Solar Cells

... is necessary to go back to some basic atomic concepts. In the simplest model of the atom, electrons orbit a central nucleus, composed of protons and neutrons. each electron carries one negative charge and each proton one positive charge. Neutrons carry no charge. Every atom has the same number of electrons as there are protons, so, on the whole, it is electrically neutral. The electrons have discrete kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into ...

Creatine 2

... of Creatine include muscle tears and pulls, liver and kidney damage, constriction of the blood vessels around the heart, pancretitis, and asthma. Muscle tears and pulls are said to be linked to Creatine when used in physical activity. Reasons for pulls and tears are the fast growth of the muscles. This can cause muscles to be tighter than usual causing pulls and tears. Liver and kidney damage are caused by Creatine increasing the amount of ATP (adenosine tryphosphate) that is used for energy, made by the kidneys, which can cause the kidneys ...

Endangered Species Study: Jaguars

... areas to scrub lands and grasslands. II. Jaguars are part of the life cycle of many species. Killing jaguars for protection and furs are ruining other species that live in the same range as them. These cats are of no harm to human life, most deaths that jaguars have had a part in were to protect themselves from being killed. Many jaguars just disappear from the pressures of being killed. While the animal is trying to change habitats they have died. The rain forests that the jaguars inhabit are being torn down to open up lumbering, f ...

There are two different types of burrows, dwelling burrows, and nesting burrows. The nesting ...

Grasshopper Dissection

... to lay the specimen in while we were dissecting 3) we used a whole bunch of little pins to hold the specimen open and expose the insides. 4) we used a bit of water to wash the formaldehyde, alcohol solution from the specimen 5) we used tweezers to pull the mouth parts and head from the specimen. 6) we used a light so that we could see all the internal parts to the grasshopper clearly. I found this to be a very educational experience not just for me but for my whole group, I know this because I could see them concentrate and do ev ...

Anabolic Steroids

... a magic pill. A magic pill that will transform a 130 pound weakling into the hulk in a month. Steroids alone do not make muscles grow. They only aid in muscle growth. Steroids basically speed up muscle repair and slow down the body’s natural tendency to break down muscle. Popular media has insinuated to the public about horror stories and the dangers. If they are so dangerous then why do doctors prescribe them? Why do pharmacies all over the planet still make them and sell them? To have an opinion on whether steroids are safe are no ...

The Effects Of Over-Population On The Earth's Water Supply

... thirty billion in another one hundred years. Some sources say that the Earth can support this exponential growth rate, others say that it cannot. Some of these sources recount statistics of a slowing population growth, however, the most appalling facts are that the planet Earth's water resources are depleted now. How can we allow the population to grow unchecked, when we know that even now, the Earth's water supplies are taxed to the limit? The subject of over-population encompasses many areas of study. Some examples are health, food, pollutio ...
