Daltons Atomic Theory
Number of words: 371 - Number of pages: 2.... and weight relations in chemical reactions. He was the first to associate the ancient idea of atoms with stoichiometry.
The existence of atoms was first suggested more that 2000 years before Dalton's birth. (Newton's speculations about atoms in the Principia were carefully copied by hand into Dalton's notebooks.)
Atoms of an element cannot be created, destroyed, broken into smaller parts or transformed into atoms of another element. Dalton based this hypothesis on the law of conservation of mass and on centuries of experimental evidence.
Some of the detail .....

Solutions Around You
Number of words: 543 - Number of pages: 2.... a solution are evenly disturbed, or intermingled informally on a molecular level. A small sample of one part of a solution. The particles in a solution will not separate no matter how long the solution is allowed to stand under constant conditions. In a solution, one substance is usually considered to be dissolved, or broken down in another. The substance that is dissolved is called the solute. The substance that does the dissolving is the solvent. Not every substance dissolves in every other substances. A substance that dissolves in another substance is .....

The Effects Of Foreign Species Introduction On An Ecosystem
Number of words: 643 - Number of pages: 3.... for the native species.
Once the new species has found its ecological niche however, balance begins to
restore itself.
When the biodiversity in the ecosystem is reduced, the ability of the
ecosystem to grow, or the biotic potential, is as well reduced. More species
residing in an ecosystem which depend on each other allows for a greater chance
of survival and perpetuation. This may occur for several reasons, for example a
bee and a flower. The bee requires the pollen of the flower to make its honey.
However, while gathering the pollen from the flower .....

Network 2
Number of words: 448 - Number of pages: 2.... of networks. At one time, all of the different networks used different protocols. A user could talk to others on their network, but not to someone on a different network. The protocol TCP/IP solves this problem. It is what allows a person on one network to communicate with a person on a different network.
When I mentioned something to share in the network definition, it can be anything, an idea, document, or greeting. Networking allows use of applications on other computers, electronic mail (email), and real time discussions in chat rooms. The .....

Soil Salinity
Number of words: 286 - Number of pages: 2.... of water from the topsoil to the groundwater, due to
rainfall or irrigation, can result in a dramatic rise in groundwater pressure
and watertable levels.
The trees of the open forests are now replaced by shallow-rooted crops and
pastures which absorb far less water than the native trees. Those trees had been
massive water pumps, sucking up moisture from deep underground and putting it
back into the atmosphere through the evaporation from their leaves. With those
pumps gone, excess rainfall accumulates underground and watertables rise to the
surface, bringing ancient sediments of salt with them, ofte .....

Evolutionism
Number of words: 322 - Number of pages: 2.... DNA, the evidence supporting evolution has greatly increased.
Charles Darwin was one scientist who helped to increase the evidence supporting
evolution. Darwin developed the idea of “natural selection” where living things that reproduced
in large numbers and survived became dominant and other living things adapted to survive, or
they died. Francis Crick, a scientist, co-discovered DNA which opened new doors to the idea of
evolutionism (History). DNA is the pattern by which people are created as individuals. Now
Evolutionism is the only origin of lif .....

The Effects Of UFO's On People
Number of words: 1089 - Number of pages: 4.... people who claim to have seen them. Since UFOs were considered
a potential security risk, the report on these sightings was originally
classified as secret. (Craig, 917) When the report was later declassified it
showed that 90 percent of all UFO sightings could be easily explained. Most of
the sightings turned out to be celestial objects, such as stars or bright
planets like Venus, or atmospheric events such as auroras or meteors falling
through the atmosphere. Many other sightings turned out to be objects such as
weather balloons, satellites, aircraft lights, .....

Nuclear Weapons And Their Hazards
Number of words: 821 - Number of pages: 3.... 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 .....
