Diamonds

... Despite the fact that they have identical chemical composition, the two minerals are drastically different. Diamond is the hardest known substance and is usually light colored and transparent, while graphite is greasy, easily powdered, and very dark in color. Diamond is the hardest gem on Mohs’ hardness scale and graphite is the softest. Diamond is very hard because of its dense packing and interlocking atomic arrangement. Graphite, on the other hand, although it is the same element, is more loosely packed and has a six-sided, layered co ...

Acid Rain 6

... atmosphere, it oxidizes to first form a sulphate ion. It then becomes sulphuric acid as it joins with hydrogen atoms in the air and falls back down to earth. Nitric oxide and nitric dioxide are also components of acid rain. Its mainly caused by exhaust fumes. Like sulphur dioxide, the nitrogen oxides rise into the atmosphere and are oxidized in clouds to form nitric acid. One of the most serious impacts of acid precipitation is on forests and soils. A lot of damages are being done when the sulphuric acid falls onto the earth as rain. ...

Surface Area To Volume Ratios In Plants (Arid Vs. Moist Environments)

... for example, is expected to have a high surface area to volume ratio. If weather patterns were to suddenly change due to a global warming trend, how would this affect the plant’s growth and ability to photosynthesize? These are the questions that lie at the basis of the following experiment. Objective: To determine how the presence or absence of water in the environment affects the surface area to volume ratios in plants. It is observed that plants in moist environments have more lush, larger foliage, while plants inhabiting ...

Nervous System

... fibers called axons carry sensory information and motor commands in the PNS. Sketch and label the structure of a typical neuron and describe the function of each. * The soma, consists of the cell body of a neuron which further contains the nucleus. * Glial cells interact with neurons and regulate the extracellular environment, protect against pathogens and repair damaged neural tissue. * Axons are-capable of propagating nerve impulses. * Dendrites respond to specific stimuli in the extracellular environment. ...

Fossil Fuels: Our Society's Dependency

... past events it points to the supply and demand scenario. During World War II rubber supplies were cut off to the western world and we began to work on a compound that was a synthetic rubber. We succeeded in supplying the demand and now that same synthetic compound is used today. My theory is that the same thing will happen with such things as plastic, which is made from fossil fuels. Someone will either come up with a synthetic plastic or come up with something to substitute for plastic. The person who comes up with the solution will bec ...

Marijuana And Its Effects On Humans

... Physically, cannabis is relatively harmless. Studies have observed interesting results, including that it causes structural changes in the brain, depresses male sperm counts, causes chromosome damage, lowers testosterone levels, and damages the lungs. Most of these claims, however, have been unreplicated in humans or have been contradicted by other work. This section will address each of these reported negative side-effects. Various studies have claimed that cannabis destroys brain cells. However, several other studies found no structural o ...

Salt Water Can Support An Electrical Current

... most abundant. The less abundant substances are called solutes. The solvent is always a liquid and in most cases the solvent is water but it is not limited to water. Alcohol is also a common solvent. Solutes are usually solid substances, and they are not limited to only being solids, for example another liquid can be the solute. Some liquids can dissolve in each other in any proportion; others have limits. If a solute added to a solution above a certain amount will not dissolve, the solution is called saturated. For most substances, solu ...

Hereditary Colon Cancer

... is passed from parents to their offspring through the genes. accounts for 21 percent of all colon cancers. Familial Adenomatous Polyposis Coli (FAP) is very rare and only accounts for one percent of all cases. If a person had FAP, they would develop hundreds or even thousands of colon polyps. These polyps are developed at a very young age, Some people have been known to be as young as 13years of age. Most colon polyps are benign but some become cancerous.

The Beginning Of The Universe

... in the primeval fireball--an extremely hot dense state from which the universe rapidly expanded.1 The Big Bang was the start of time and space. The matter and radiation of that early stage rapidly expanded and cooled. Several million years later, it condensed into galaxies. The universe has continued to expand, and the galaxies have continued moving away from each other ever since. Today the universe is still expanding, as astronomers have observed. The Steady State model says that the universe does not evolve or change in time. There wa ...
