Effects Of Secondhand Smoke
Words: 314 - Pages: 2.... smoke (www.alaw.org). It can also exacerbate frequent attacks. Babies are three times more likely to die form Sudden Infant Death Syndrome (SIDS) if their mothers smoke during pregnancy. Ear infection, coughs, sore throat and even cancer can also develop if children are expose to secondhand smoke.
With all these harmful to children, there are ways to protect them from it. First, as a parent, don’t smoke. If you are a smoker, quit! If you can’t, don’t smoke in your house, in the car or near your children. Have a permanent place outside the house just for smoking purposes only. Make sure that your child's day-care, school or playgro .....

Involvement Of K+ In Leaf Movements During Suntracking
Words: 2307 - Pages: 9.... as severe
(Donahue and Vogelmann). Under these conditions the lamina of the leaf is
within less than 15° from the normal to the sun. Many plants that exhibit
diaheliotropic movements also show paraheliotropic response as well.
Paraheliotropism minimizes water loss by reducing the amount of light absorbed
by the leaves; the leaves orient themselves parallel to the sun’s rays. Plants
that exhibit paraheliotropic behavior usually do so at midday, when the sun’s
rays are perpendicular to the ground. This reorientation takes place only in
leaves of plants that are capable of nastic light-driven movements, such as the
trifoliate leaf of .....

How Mountains Are Formed

pushed against the African plate. Other examples of folded mountains are the
Rockies, Himalayas, Appalayas, and the Andes. Fault-block mountains are
formed when one plate pushes or pulls away from another plate. In the Earth,
hot currents of magma or molten rock may well up and crack the weakened
crust above. As the crust cracks, blocks of rock rise or fall forming
Fault-block mountains. Examples of these mountains are the Sierra Nevada in
California and the Grand Tetons in Wyoming. Dome mountains are formed
by the same kind of molten rock that forms Volcanic mountains. As magma
comes up in a crack in the Earth .....

Intranets have just started to be implemented throughout the world and already a big change is being noticed. Companies are keeping track of all of their important information on web sites, which are restricted to users, unless they have the security code to access them. Thanks to Internet technology, companies and other types of organizations are able to keep all of their information organized and easily accessible with a click of a button.
The Internet, how has it changed the world around us? Government, education, business is all wrapping around it. Is this because of all of the information .....

To What Extent Does Acid Precipitation Affect Annelids?
Words: 641 - Pages: 3.... rest comes from various oxides of nitrogen (mainly NO2 and NO3, collectively called NOx). These gases are produced almost entirely from burning fossil fuels, mainly in power satations and road transport. (Kucera, (1973) The Challenge of Ecology, The Mosby Company.) Tremendous quantities of this nitric acid and sulfuric acid mix are reflected in the lowering of the acidity of rain.
Earthworms (Annelids) are a species of worm which are many segmented. They live in damp soil, usually forming intricate tunnels beneath the surface. Their bodies are lond and cylindrical, and have "bluntly tapered ends and are somewhat depressed posteriorly." (St .....

Bioethics
Words: 1691 - Pages: 7.... there have been clear documented cases of abuse in recent times.
An example of this is the experiments conducted by Nazi doctors on prisoners in
the concentration camps during the Holocaust.
Does this mean that since there is potential for abuse, all
experimentation should be banned? This would mean that society would be
condemned to remain at the same level of knowledge (status quo)?
Bioethically speaking, how far can we go in the study of the human
without crossing the line? The fundamental question is, since we are the ones
drawing the line, where do we draw it?
The purpose of this essay is to provide a clear sense o .....

Genetic Faltering
Words: 1793 - Pages: 7.... planet.
As of 1998, many experiments have been done in the field of genetics, in the next section, I will discuss a few.
First, genetics came into the public view in the early 1970’s when a scientist named Paul Berg began experimenting with a strain of E.coli bacteria called SV40. (Tagliaferro 69) This was the public beginning to the struggle surrounding genetics. Berg was not very intelligent about the way he conducted his tests, and he was forced to stop, until the National Institute of Health determined that SV40 was harmless to humans. (Tagliaferro 70)
The next major happening in genetics was the Asilomar Conference of 1973. T .....

research to try to explain these occurrences.
"It may be valuable to carefully evaluate UFO reports to extract
information about unusual phenomena currently unknown to science," the
report stated, adding that such research could also improve understanding
of, and in some cases debunk, supposed UFO events.
For example, Earth science researchers have eventually accepted several
phenomena "originally dismissed as folk tales," including meteorites and
certain types of lightning, the panel noted.
The findings are from a four-day workshop held in Tarrytown, N.Y., followed
by a .....

Could The Greenhouse Effect Cause More Damage?

Earth's temperature to increase by any-where from three to nine degrees. The
Vostok record confirms that," says Harte.
The grid is divided into ten sections. Each of the ten sections covers
thirty square yards of the meadow. The infarared lamps will heat every other
section by 2.5 degrees. The unheated sections in between allow researchers to
compare the efects of the lamps with the regular state of the meadow.
One time a week, Harte will take gas samples from buckets turned upside
down for ten minutes at a time on both the heated and unheated strips through
fitted nippl .....
