Bioethics
.... 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 of the pre .....

Bioluminescence In Fungi
.... called "Luciferin" and the reaction was catalyzed by an enzyme called
"Luciferase". The light generated by this biochemical reaction has been
utilized by scientists as a bioindicator for Tuberculosis as well as heavy
metals. On going research involving bioluminescence is currently underway in
the areas of evolution, ecology, histology, physiology, biochemistry, and
biomedical applications.
History of Bioluminescent Fungi
The light of luminous wood was first noted in the early writings of
Aristo .....

Biome Broadcast
.... to the trails. We had
to decide what trail to take. We had three choices the first trail was half a
mile long, the second trail was two miles long, and the third trail was four
miles long. Since it was such a beautiful day we all decided to take the third
trail that was four miles long.
We started hiking around 11:00 AM. While we were hiking we heard wings
flapping, we all turned and saw a robin fly towards the ground, pick up a worm,
and feed it to her babies. Everyone thought that it was cute. Aft .....

Biotechnology
.... to their own personal, perhaps evil,
advantages.
Dealing with politics, Bioengineering has opened a whole new
door pertaining to the military, whose use of it may create an
ultimate destruction. The alterance of nature is un-natural, and creates
an unbalancement in life. When we use this technology towards the
wrong side, we may all be burned. You see, Biotechnology has the
ability to altar what diseases we humans are susceptible to, and when
scientists create something to eliminate immunities to dis .....

Birds
.... can stand almost eight feet high and can weigh near 350
pounds. Other extinct birds have been measured to stand over ten feet high.
The evolution of birds is still being argued. Most people believe that
birds evolved from reptiles. Because of birds mainly delicate bones, few fossils
have been left behind for scientists to study. The earliest bird fossils come
from archaeopteryx. The fossils that have been discovered from archaeopteryx
include six partial skeletons and one single feather. Archaeopt .....

Roswell Incident
.... and how the public
thinks of themselves, God and the outer limits of space!
Roswell New Mexico was in the middle of the desert. Here was a vast
open land where one could see miles around. On this afternoon something very
strange was about to happen. In the clear skies of Roswell a very large craft
ended its flight. Was this a weather balloon or an Unidentified Flying Object?
There were many eye-witness reports of alien creatures lying next to
their destroyed crafts. One or two may have surv .....

Stars
.... a "v".
What are apparent and absolute magnitudes? Apparent is how bright the appear to
us in the sky. The scale is somewhat arbitrary, as explained above, but a
magnitude difference of 5 has been set to exactly a factor of 100 in intensity.
Absolute magnitudes are how bright a star would appear from some standard
distance, arbitrarily set as 10 parsecs or about 32.6 light years. Stars can be
as bright as absolute magnitude -8 and as faint as absolute magnitude +16 or
fainter. There are thus (a very few) .....

Carnivorous Plants
.... chlorophyll. This pigment helps to mediate a
chemical process called photosynthesis. This converts light energy into the
chemical bond energy of carbohydrate which is utilized as cellular energy, plant
growth and development. Water, carbon dioxide, nutrients and minerals are also
needed for survival. In wetlands, where stagnate water contains acidic
compounds and chemicals from decaying organic matter many plants have a
difficult time obtaining necessary nutrients. It is in these nutrient poor

Cells
.... mitochondria, which provides energy to the cell through ATP and respiration.
Then there is the endoplasmic reticulum which separates parts of the cell. Then
there is the Golgi apparatus which is used for sorting, storing, and secretion
for the cell. Next are lysosomes, which hydrolyze macromolecules. Then there
are centrioles that play a major role in cell division. And lastly there are
vacuoles which have a variety of storage functions.
The plant cell is similar in most ways. The only really .....

Damn Near Everything There Is To Know About Cells:
.... cells, help anchor cells together,
and allow cells to communicate with one another by passing small molecules from
one cell to another. Groups of two or more tissues that function together
make up organs. An organ system is a group of organs that work together to
carry out major life functions.
Eukariotic Cell Structure:

the cellular membrane. It is the outermost part of the animal cell, and it .....

History Of The Cell Theory
.... and animal tissues. Along with Matthias Jakob Schleiden
a German botanist, Schwann proposed the cell theory.
The cell theory has three parts:
1. All organisms are composed of cells.
2. Cells are the basic units of structure and function in organisms
3. All cells come from preexisting cells.
The impact on science was very great due to the discovery of cells and
the cell theory. Many or all things were effected by the discovery of cells,
everything was looked upon in a different way. S .....

Stephen J. Hawking By Rachel Finck
.... freedom to think about physics and the Universe.
Stephen Hawking has written many essays involving the unified theory,
which is a theory summarizing the entire of the physical world; a theory that
would stand as a complete, consistent theory of the physical interactions that
would describe all possible observations. Our attempts at modeling physical
reality normally consists of two parts: a) A set of local laws that are obeyed
by the various physical quantities, formulated in terms of differential
eq .....

Chimpanzee Versus Humans: Similarities & Differences
.... twice as large as that of the chimp. Humans have a brain capacity of 1300
to 1500 cc, while the chimps are about 600 - 800 cc. It is though by scientists
that our brain size grew over time as were evolved into making complex tools and
we became increasingly sophisticated. The human skull is slightly different
from that of our primate ancestors, these changes occurred over thousands of
years of evolution. Over time the humans skull and teeth have decreased from
that of our ancestors. The chimp has much .....

for in greek, it means "route of animals."
The sun enters the first zodiacal sign, Aries , and then continues its path
through the remaining eleven signs. The twelve signs of the zodiac are: Aries,
Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn,
Aquarius, and Pisces.
The moon and the planets pass through the signs too, but obviously at
different speeds from those of the sun .....

Cloning Of Animals
.... The tadpoles,
however, never matured into frogs.
The Scottish researchers have failed many times with sheep cells before
their success, but the task was perfected and accomplished. Now this
accomplishment has made it possible for the cloning of almost any mammal,
including humans.
To the average person, exactly how the technique works is unclear.
Scientist predicted that by making cells dormant and bringing them close to
death, something happens to break the chemical locks (barriers) that keep m .....
