Avalanches And Landslides
583 Words - 3 Pages.... Canada it destroyed the parks canyons it's beautiful trees'
it's wonderful sights and killed nearly one hundred people, and covered a small
town near Alberta with ice and snow.
Another devastating avalanche incident is the 1964 Sherman slide, in which a
huge avalanche was triggered by the 1964 Alaskan earthquake. The slide spilled
out onto the Sherman glacier, during the big slide several other smaller slides
happened and those were the one that took lives in Anchorage, and destroyed
property
There are a couple of types of avalanches and how the destroy so much this one
is named "Loose Snow Avalanches"1, it starts' in a small area then grows in size
and mass as it d ....

Wired Hands - A Brief Look At Robotics
1193 Words - 5 Pages.... that holds tools such as welding guns or motorized
screwdrivers or grippers for picking up objects.
The robots working at Chrysler and in numerous other modern factories are
extremely adept at performing highly specialized tasks - one robot may
spray paint car parts while another does spots welds while another pours
radioactive chemicals. Robots are ideal workers: they never get bored and
they work around the clock. What's even more important, they're flexible.
By altering its programming you can instruct a robot to take on different
tasks. This is largely what sets robots apart from other machines; try as
you might you can't make your washing machine do the dishes. Alth ....

Eye
2091 Words - 8 Pages.... once every six seconds. This washes the with the salty secretion from the tear, or lachrymal, glands. Each tear gland is about the size and shape of an almond. These glands are located behind the upper lid at the outer corner of the . After passing over the , the liquid from the gland is drained into the nose through the tear duct at the inner corner of the .
Heavy laughter or crying causes muscles in the upper lid to squeeze the lachrymal gland. This produces tears that flow too fast to be drained away. The lashes catch many flying particles that otherwise would enter the . As further protection, the lids automatically close when an object suddenly moves close to the . ....

Surface Tension
617 Words - 3 Pages.... is the force per unit length of any
straight line on the liquid surface that the surface layers on the opposite
sides of the line exert upon each other. The tendency of any liquid surface is
to become as small as possible as a result of this tension, as in the case of
mercury, which forms an almost round ball when a small quantity is placed on a
horizontal surface. The near-perfect spherical shape of a soap bubble, which is
the result of the distribution of tension on the thin film of soap, is another
example of this force; surface tension alone can support a needle placed
horizontally on a water surface.
Surface tension depends mainly upon the forces attraction betwee ....

Dna
977 Words - 4 Pages.... double helix. Each nucleotide consists of three units: sugar molecules called deoxyribose, a phosphate group, and one of four different nitrogen containing compounds, also called bases. The four are adenine (A), guanine (G), thymine (T), and cytosine (C). The deoxyribose molecule occupies the center of the nucleotide, with the phosphate group on one side and a base on the other. The phosphate group of each nucleotide is also linked to the deoxyribose of the adjacent nucleotide in the chain. These linked deoxyribose-phosphate subunits form the side rails of the ladder. The bases face inward toward each other, forming the steps of the ladder.
The nucleotides in one strand have ....

Black Holes
688 Words - 3 Pages.... mass of the body divided by the mass
of the sun). If a body is electrically charged or rotating,
Schwarzschild's results are modified. An "ergosphere" forms outside the
horizon, within which matter is forced to rotate with the black hole; in
principle, energy can be emitted from the ergosphere.
According to general relativity, gravitation severely modifies
space and time near a black hole. As the horizon is approached from
outside, time slows down relative to that of distant observers, stopping
completely on the horizon. Once a body has contracted within its
Schwarzschild radius, it would theoretically collapse to a singularity—that
is, a dimensionless objec ....

Turner Syndrome
1105 Words - 5 Pages.... chromosome
material. Turner's Syndrome is a rare chromosomal disorder that affects
one in approximately 2,500 females. Females normally have two X-
chromosomes. However, in those with Turner's Syndrome, one X chromosome is
absent or is damaged.
OTHER NAMES Depending on the doctor, Turner's Syndrome may be diagnosed
with one of the following alternative names: 45 - X Syndrome, Bonnevie-
Ulrich Syndrome, Chromosome X, Monosomy X, Morgagni-Turner-Albright
Syndrome, Ovarian Dwarfism, Turner Type, among others.
SYNDROME CHARACTERISTICS A reduced growth in height is the commonest
visible characteristic of the syndrome, (the average adult height is 4
feet 8 inches) and may be the ....

Bullfrogs Hearing Capacity
988 Words - 4 Pages.... I have determined the latter, I would like to see how well a bullfrog is able to distinguish a specific frequency from other frequencies.
For both experiments, I would need to obtain a number of bullfrogs from a natural habitat and place them in the lab made habitat, which would be similar to the one that they were removed from. Hopefully, the frogs will adapted to the new habitat and carry on as they did in their old habitat. Tampered bullfrogs such as those raised in labs or pets would not be used because the results would be inaccurate. The inaccuracy would be that these "tampered frogs" have been out of the wild for so long that they would not have the same range of ....
