Title: Does Life Exist On Mars
Details: Words: 381, Pages: 2... however don't believe that living cells of any kind have ever existed in this
solar system apart from on earth. I do see the possibility that maybe other
solar systems is our solar system in history which is an interesting thought.
Just because NASA has found a single cell living creature in a meteorite doesn't
prove anything in my mind. Especially because of the fact that it has been on
earth for 12 years when over this time the cell could have attached itself to
the meteorite.
Nobody knows enough about the subject to start telling the public that this is
true, they should have never released it unless it were defiantly proven to be
fact. NASA has a big name in ...

Title: Nuclear Weapons And Their Hazards
Details: Words: 821, Pages: 3... importantly in these regions rainfall would probably
decreases because monsoons could not develop. Like in On The Beach, all
the radiation move towards Australia and everyone innocent people died.
A large-scale nuclear war would lessen food production over large
expanses in the Northern Hemisphere, this could occur through acute
climatic conditions which chilling or freezing temperatures occurring for
brief periods during the growing season which could destroy crops or lower
production. As result of the variety of potential physical and societal
disruptions to agriculture from a large-scale nuclear war, agriculture in
the Northern Hemisphere could be shut ...

Title: Ebola Virus 4
Details: Words: 2184, Pages: 8... a membrane made of 10 nm projections, and host cell membrane. They contain a unique single-stranded molecule of noninfectious (negative sense ) RNA. The virus is composed of 7 polypeptides, a nucleoprotein, a glycoprotein, a polymerase and 4 other undesignated proteins. Proteins are produced from polyadenylated monocistronic mRNA species transcribed from virus RNA. The replication in and destruction of the host cell is rapid and produces a large number of viruses budding from the cell membrane.
Epidemics have resulted from person to person transmission, nosocomial spread or laboratory infections. The mode of primary infection and the natural ecology of these vi ...

Title: Nuclear Waste Disposal At Yucca Mountain: Right Or Wrong?
Details: Words: 976, Pages: 4... of this money comes from individual investors. If a
retrievable facility (one where the casks of spent fuel can be retrieved later)
is built, this will be a good deal more. Other disposal types, such as sub-
seabed and space disposal may prove to be cheaper at a later time.
This is a cause for concern, but there are a greater amount of reasons
to further and eventually finish the Yucca Mountain Project. One is the desert
climate naturally occurring in the western United States. The weather is dry
and warm and their are very few natural disasters, such as earthquakes. Also,
this part of the nation has a lower water table than the rest of the country.
This re ...

Title: Male Pattern Baldness

usually is a symmetrical disease, so if there is a non-symmetrical area of baldness, it is not the cause of androgenic alopecia. The typical pattern begins of occur at the hairline, then over time forms an “M”. The crown also begins to become thinner, as does the existing hair. Eventually, the “m” meets the thinned crown and forms the most common bald shape, the horseshoe.
Currently, there are no treatments for male pattern baldness, so the condition is permanent. But, no treatment should be required if the person is comfortable with the ...

Title: Manatees
Details: Words: 1737, Pages: 7... for
some whiskers on their face, and they have internal ears on the sides of their
head. Their nostrils are closed by valves, so they can accomplish such feats as
flips and quick turns without losing any air. Manatees have no hind legs, but
instead one big, flat, spatula-like tail (Sentman 327). This feature made people
confuse manatees with mermaids for nearly four centuries (O'Shea 66).
Many biologists say that manatees possibly originated or evolved from
ungulates such as elephants and cows because of the way that they are built, and
certain features that they have in common. Like elephants, manatees have the
peculiar half-moon shaped fingernails, and thick, ...

Title: Time To Change
Details: Words: 747, Pages: 3... impact on the degeneration of natural resources. Millions of
gallons of oil, coal, and other valuable resources are wasted each day. These
are just a few of the human disruptions to nature available to our knowledge.
We are conscious of many more, and there are probably others that we are not
aware of. If we do not start taking them seriously soon it will be too late,
if it is not already. We need to reevaluate our priorities and plan for the
future existence of this world.
A group labeled the Earth-Firsters' often attempt to accomplish this task
through drastic and sometimes dangerous methods. As Joni Seager states ( The
Eco-Fringe: Deep Ecology, Pg. 636), ...

Title: Computers That Mimic The Human Mind
Details: Words: 1465, Pages: 6... most recent technological advances, then it would be obvious that computers and software are beginning to mimic even the most advanced mental states. In the future, computers will be able to do anything the human mind is capable of thus proving Eliminative Materialism to be a sound solution to the mind-body problem.
Most of the day the human mind is taking in information, analyzing it, storing it accordingly, and recalling past knowledge to solve problems logically. This is similar to the life of any computer. Humans gain information through the senses. Computers gain similar information through a video camera, a microphone, a touch pad or screen, and it is ev ...

Title: The Greenhouse Effect
Details: Words: 463, Pages: 2... trees is cleared by either being logged
or burnt. Two other deadly greenhouse gasses which are entering the atmosphere
even faster than carbon dioxide are methane and chloroflourocarbons, although
they are not as damaging in the long run.
These increases are likely to affect worldwide temperatures
dramatically. In 100 years time the average temperature for most parts of the
world will increase from between 2C to 6C if greenhouse pollution continues at
its present rate. This temperature increase would drastically affect the growth
of many different crops and cause the polar ice caps to melt, thus increasing
sea levels to rise up to several metres. I ...

Title: Hail
Details: Words: 1296, Pages: 5... hailstone weighed 1.671 pounds and
was 17.5 inches in circumference. The largest stone previously on record
was almost the same size. It was found in Potter, Nebraska on July 6, 1928.
The hailstone had a circumference of 17 inches and weighed 1.51 pounds
(Dennis 54).
Hail can be extremely dangerous. It can break windows, damage
roofs, dent cars, injure and even kill people! Crops are greatly affected.
Hail causes around two hundred million dollars in damage a year. That's a
lot of money. When the wind is blowing hailstones are at their worst.
The most common places to see hail is in Texas, through the Great
Plains and up into Alberta, Cana ...
