Mars 3

... as our air, but even this small amount can condense out, forming clouds that rise high in the atmosphere or swirl around the slopes of towering volcanoes. Local patches of early morning fog can form in valleys. At the Viking Lander 2 site, a thin layer of water frost covered the ground each winter. There is evidence that in the past a denser Martian atmosphere may have allowed water to flow on the planet. Physical features closely resembling shorelines, gorges, riverbeds and islands suggest that great rivers once marked the planet.
Mars is smaller and, because of its greater distance from the Sun, c ...

The Effects Of Antibiotics On Bacterial Growth
Number of Words: 1287 / Number of Pages: 5
... process. Spherical bacteria are called cocci; the bacteria that
have a rodlike shape are known as bacilli; corkscrew shaped bacteria are
spirilla; and filamentous is the term for bacteria with a threadlike appearance.
Hans Christian Joachim Gram, a Danish microbiologist, developed a method
for distinguishing bacteria by their different reaction to a stain. The
process of applying Gram’s stain is as follows: the bacteria are stained with a
violet dye and treated with Gram’s solution (1 part iodine, 2 parts potassium
iodide, and 300 parts water). Ethyl alcohol is then applied to the medium; the ...

Atom Book
Number of Words: 280 / Number of Pages: 2
... like.
We're going to into the Helium atom today. An atom is made of little things
called protons, nuetrons, and electrons. Protons have a positive charge,
neutrons have no charge, and electrons have a negative charge. Electrons travel
around the center of the atom, which is called the nucleus. Kind of like how
Earth revolves around the sun. Protons and nuetrons make up the center of the
atom.
The atom has an atomic number. Scientists find that number by counting how many
protons are in the nucleus. In this case Helium has two protons.
Scientists find the average atomic mass by adding up protons a ...

Lab: Determining What Type Of Stimulus Info Is More Easily Remembered

... be it in randomized manner or
meaningful. When are more errors made in remembering the stimuli, among
these two types of stimuli used (CVC). Also, when a correct response is
given, which was the type of stimuli (CVC) that caused this to occur.
The design of this experiment on verbal learning has both within-
subject and between-subject variables. The within-subject variables are
the words (CVC) that are stored in the computer which are the default words
to be used. The between-subject variables are the number of stimuli used
and the choice of the stimuli using the experimenters own words ...

The Monkey

... divergent from the others. Commonly, the
digits have flattened nails, but those of the marmoset are an exception.
Except for the night-roaming durukuli of tropical America, monkeys are
active during the day, moving frequently in bands in search of vegetation,
birds' eggs, smaller animals, or insects to eat. Monkeys are highly social
animals and are often organized in clans headed by an old male; these clans
are rigidly defined in such species as howlers and baboons.
As in all primates the brain is comparatively large. This feature, combined
with the freeing of the hands and a well-developed visio ...

Black Smokers
Number of Words: 438 / Number of Pages: 2
... until recently, smokers have only been observed by videotape and "deep-diving submersibles". Last summer a team from the University of Washington and the American Museum of Natural History accomplished the task of bringing four "" to the surface. The method that the team used for retrieval was quite interesting. The team followed a "loggers technique" for detaching the smoker from the Earth’s crust. They used a "choker", like the cables loggers use to drag downed trees to waiting trucks. Another "logger technique" that the team used was a chainsaw. But this one was different it was hydraulically ...

Animalia Vertebrata Mammalia Carnivora Canidae Canis Lupus And Animalia Vertebrata Mammalia Carnivora Canidae Canis Niger

... most of western Europe as well. In Spain, two
wolves have also been identified-Canis lupus deitanus and Canis lupus signatus.
While the first is similar to many of the other European wolves, the latter may
be more closely related to the jackal (Canis aureus), than to a wolf. The
Caucasion Wolf (Canis lupus cubanensis) is found in many parts of eastern Europe
and western Asia. The large tundra wolf of eastern Asia, the Tundra or Turukhan
Wolf (Canis lupus albus), is very close in relations to the wolves of northern
Alaska.
In the Arctic Islands and Greenland the Melville Island Wolf (Canis
lupus arct ...

The Search For Black Holes: Both As A Concept And An Understanding
Number of Words: 2169 / Number of Pages: 8
... clarification will come by the close of this essay.
A black hole is probably one of the most misunderstood ideas among
people outside of the astronomical and physical communities. Before an
understanding of how it is formed can take place, a bit of an introduction to
stars is necessary. This will shed light (no pun intended) on the black hole
philosophy.
A star is an enormous fire ball, fueled by a nuclear reaction at its
core which produces massive amounts of heat and pressure. It is formed when two
or more enormous gaseous clouds come together which forms the core, and as an
aftereffect the con ...

The Prairie Dog: Friend Or Foe?
Number of Words: 1768 / Number of Pages: 7
... of available potential habitat.
Prairie dogs are essential to our prairie ecosystem. Many species dependent on prairie dogs for prey and habitat are diminishing in direct relation to the decreasing number of prairie dogs. Unlike other species, which have declined because of habitat loss due to human activities, the loss of prairie dog populations is a direct result of governmental and private landowner efforts to eradicate them. Prairie dogs and their environment must be protected by law to preserve our native prairie ecosystem.
Tim Clark, a Yale University biologist and a veteran of years of o ...
