Chromosome Probes At The University Of Toronto

... probes or markers for six plus the gender determining X and Y chromosomes. "What we're trying to decide now is whether to isolate probes for the other chromosomes, or whether we should utilize the eight we have," he says. Dr. Willard is currently negotiating with an American company to develop prenatal diagnostic tests, which, because the current tests are time consuming and technically difficult to do, are restricted to women over 35 and those who have a family history of chromosomal abnormalities. Prenatal tests using Willard's probes wo ...

Black Powder

... One importance is that is probably the best substance that we have for communicating fire and for producing a quick hot flame, and it is for these purposes that it is now principally used in the military art. Standard is used in petards, as a base charge or expelling charge for shrapnel shells, in saluting and blank fire charges, as the bursting charge of practice shells and bombs. Despite the fact that is called under one name, there are many different forms of . These are merely classified as how strong their reactions are, in ...

Xenon

... low. They are -111°C and -107°C respectively. Xenon and most of the other noble gases were discovered by Sir William Ramsey and M.W. Travers from England in 1898. The two scientists discovered it mistakenly while experimenting with crude krypton, another noble gas. They were separating the elements in the crude krypton through a process called fractional distillation. In fractional distillation, the process separates two elements that have different boiling points. Basic-ally, when a sample is heated, the faster element leaves fi ...

Bipolar Disorder 3

... a manic depressive illness. Environmental factors such as death, separation and divorce may trigger the disorder. The illness manifests itself with the individual experiencing episodes of mania or elation followed by low mood or depression.

... The goal of this organization is to identify and understand the entire genetic constitution. "They have the daunting task of identifying and mapping all of the eighty thousand genes, in human DNA, they are making new discoveries weekly" (Reuterlinkextra). With these discoveries comes many implications, In reviewing the literature genetic engineering needs to be banned because of the social, religious, ethical, and legal implications. The first step to understanding genetic engineering is to know the start of its creation. Genetics achieved ...

Avalanches

... 2) slope 3) snow instability. Secondly, there are two kinds of ; slab and loose snow. Loose snow are minor and usually never exceed 20 miles per hour. While slab are the destructive and deadly mountain slides. It is not uncommon for one of these to destroy a small town or forest. Since loose snow aren’t very dangerous, I will discuss slab . The fundamentals of how these snow masses occur, what to look for when testing and just all-together prevention. The basic chemistry behind a slab avalanche is when one layer of snow does not bond to t ...

All About Ants (almost)

... Ants are doubtlessly the most successful of all the social insects of the Hymenoptera, an order also including wasps and bees. The earliest known specimens are found entombed in the Scandinavian Baltic Amber samples which scientists date in upwards of 100 million years old (The Ant Colony Œ89). These primitive samples have evolved into the 5000 to 10000 species known today which vary amongst themselves as widely as the numbers suggest (Social Insects Œ68). These remarkably adaptive creatures are found in some form on all continents and ...

Black Smokers

... they are puffing out smoke because the minerals in the water are so dense that that it instantly turns inky black. These formations are considered so important because they are believed to contain clues to how life on earth originated.
