Dangers And Destructions Of Floods And Hurricanes
... tide is which goes up and down twice a day. When the velocities of
hurricane winds become severe the height of the waves become three or more feet
higher than the previous high tide. Coastal floods can be caused by a number of
things. Coastal floods can be caused by runoff, hurricane waves, tsunami
(seismic sea waves), and hurricane rains. Coastal flooding can not only take
part on oceans but it can also take part on lakes. Coastal flooding can be a
great danger because coast lines are very densely populated areas. In the United
States in the early 1990's 50% of the population was on a coastal county.1

Salmonella Typhi (Typhoid Fever)
... Typhi hides in beverages, most commonly milk or water. It also hides in food that is usually a foreign delicacy of some sort that has been contaminated by Salmonella Typhi in some way.
Typhoid fever usually causes high fever, head ache, sore throat, vomiting, diarrhea, skin rash, weakness, or inability to think clearly. The symptoms take about two weeks to go away if they don\'t lead to death.
This bacterial pathogen is considered extremely dangerous and is probobly armed. Salmonella Typhi has been on the loose for many years and was cuased a lot of havoc and done a lot of damage over the years.
Typhoid fever ...

Creation, Evolution And Intervention: Which Theory Is Correct?
... and evolved into many different species including humans. This
theory also states that humans and other species continue to evolve today and
as a result of all these changes they will eventually become a totally different
species then what they are now. Evolutionists believe that evolution has created
many organisms spread across the globe, some of which have become extinct and
some of which are the plants and animals which live today.
The theory that groups of organisms can be transformed into different organisms
has been suggested many times since the early 1800s, when scientists began
looking for evidence t ...

Darwin's Theory And Modern Genetics
... Fourth, “Individuals of a population vary extensively in their characteristics; no two individuals are exactly alike.” And last, “Much of this variation is heritable.” This process of eliminating certain parts of a population is natural selection.
Studies were being done during Darwin’s findings that indicated there was a “gene” associated with certain characteristics. Mendel’s pea plants proved there was a way of artificially creating trends in color of flowers. This discovery led to modern genetics. We now know chromosomes carry valuable information that determines characteristics in living ...

The Atomic Bomb
... Neils Bohr, Joseph Carter, Enrico Fermi, Richard Feyman,
and Robert Oppenheimer, each with their own ideas of what it would take to
construct such a weapon.
From left to right: Neils Borh, Robert Oppenheimer, Richard Feyman, Enrico Fermi
The object of the project was to produce a practical military weapon in the form
of a bomb in which the energy would be released by a fast neutron chain reaction
in one or more of the materials known to show nuclear fission. That goal was to
be completed in 1945 after the U.S.A. spent over 6.7 Billion Dollars on the test
bomb named the "Trinity". I t was dropped on Alagormado in ...

Electric Charge
... objects with a negative charge.
Most objects are made of matter with equal amounts of positive and negative charge. Objects with the same # of positive and negative charges are electrically balanced, or neutral. Electric force is observed only when the balance of charge on objects is disturbed.
An on an object that causes the object to attract or repel other objects is called static electricity. The adjective static describes something that does not move. Charges on an object are called static electricity to contrast then with the moving charges in an electric current.
How can you disturb the balance of charge on ...

Water And Its Importance
... adhesion properties allow it to be transported in plants, and its surface tension provides a comfortable habitat for many insects. Water is also one of the best solvents. The specific heat property of water stabilizes temperature in living organisms and its high heat of vaporization regulates earth's climate. One of the most unique things about water is the fact that it expands when it freezes unlike many other liquids. Its thermal and transparent properties protect aquatic life in freezing temperatures. All of these things combined help to sustain life and keep it constantly evolving. In the next couple of pages, w ...

Solving The Mystery Of The Romanovs
... This region contains
signals that control the replication of the chromosome and the
transcription of the mitochondria genes. This DNA sequence accumulates
mutations ten times the rate of the nuclear DNA. This high mutation rate
results in unique patters of single nucleotide polymorphisms, which are
inhereited through generations. Because of the location of the
polymorphisms in the cells cytoplasm, during fertilization, mitochondria
are only passed on from the egg. This means that the mitochondria DNA is
passed on from the mother. This information becomes useful when using them
for identification purposes.

Crystals: Does Surface Tension Affect The Process Of Crystallization?
... of these crystals? This experiment has been conducted to prove
if that is true or not.
INTRODUCTION AND RESEARCH
Many scientists have been interested in crystals and the science
associated with crystals. Though one knows that certain conditions must be
present in order for crystals to form; and if some of these conditions are
not present or are not perfect, then the formation of the crystal will be
disturbed. One may ask him/herself, how is the formation disturbed if only
one of the condition would happen to be modified? Most crystals are formed
under water or under liquids with similar characters to wat ...

Sharks
... closed
around the seal with an astounding 14,000 pounds of pressure, cutting the seal
in half. The Great White shark claims another victim.1"
Any one who’s seen the famous movie series "Jaws" may look at the Great
White Shark in a similar manner. Perhaps it’s the way that Hollywood uses a mix
of fact and fiction in the series. This may have frightened many people into
hating the Great White for it’s ferocity. It might have also been the size of
the shark in the movie that’s kept thousands of people off the beaches and out
of the water. Better yet, it could have been the overall storyline: A Great
