rolled piece of paper that is twisted at the ends. A blunt is
normally an emptied cigar wrapper filled with marijuana. In a
blunt you can fit much more marijuana. Though a blunt isn't
always purely marijuana, it can be mixed with other drugs such as
angel dust.
The results are varied when someone smokes marijuana.
Different people will get different results, and certain types of
cannabis can cause different effects. The amount of THC
(marijuana's main active chemical) may also change t ...

Dsl Should Be The Standard For Telephone Lines
Number of Words: 321 / Number of Pages: 2
... If someone wanted to look something up on the internet real quick or check their mail, all they would have to do is start their internet browser or email client and they would be set.
DSL wouldn't only make our internet experience more enjoyable, but it would also improve the quality and reliability of normal phones. The digital format would be able to reproduce sound quality with great fidelity. Static-filled and "noisy" phone lines would be a thing of the past allowing for clearer long and short distance phone calls.
An upgrade to DSL would be a benefit to all. This amazing new technology would ch ...

Deinonychus Antirrhopus
Number of Words: 661 / Number of Pages: 3
... bird-like creature with characteristics similar to that of a Velociraptor ( one of the stars from Jurassic Park ). This fearsome beast was quite a ravage hunter. The Deinonychus attacked its larger prey in packs and often were successful in doing so because of their menacing claw. By hunting in groups, members of the Deinonychus pack have brought down dinosaurs much lager than themselves. Proof of this occurrence has been found today due the discovery of several individuals of Deinonychus with the skeleton of a large plant eating dinosaur, called Tenontosaurus.
These relatively small, bu ...

... black with regard to
the white palp tips (Russel 1996). The dorsal pattern of white scales on the scutum is in
the shape of a ‘lyre’ with two central based stripes that contrast with the dark scales
present on the insect (Womack 1993,
Russel 1996). Its wings are dark scaled and femur and hind legs are pale scaled for
about three-quarters, and dark scaled for about two-thirds (Russel 1996).
The first through the fourth segments of the hind tarsi are characterized by white rings
and the fifth segment is all white.
Adults can be found in abundance in towns and cities near human dwelling ...

Growth Rate Of A Seed
Number of Words: 345 / Number of Pages: 2
... can see from the data graphs at first the seeds germinated at the same rate until the tip of the radicle broke trough and was visible. Afterwards the seed which was in the light grew more rapidly then the seed which was in the dark. I think this happened because when the seed is in the early stages of germination it does not use light to grow but is controlled by phytochrome. Which is a hormone that controls the germination of a seed before it reaches light. After the radicle broke trough, the seed needed sunlight for photosynthesis, so they plant which was deprived of sunlight grew slower then the pl ...

Army Ants
Number of Words: 861 / Number of Pages: 4
... parties going out simultaneously in different directions for 100 yards or
more. In the U.S. army we attack countries in different areas to weaken the
force we are attacking. We send out thousands of troops in various directions
and try to surround the source of the location being attacked. For instance, if
there are several locations that needed to be attacked to weaken the enemy, like
their weapon storage or air force base, we send several sets of troops to attack
each individual location. This is very similar to the way army ants set out on a
hunting raid. They will send out thousands of ants at o ...

Compatisome Of Upper And Lower Rock Shores Pools
Number of Words: 3210 / Number of Pages: 12
... of the rock pool, as conditions are considerably different to those of a ‘normal’ marine environment. The rock pools spend some of their time completely submerged by the sea and other times exposed to the air. When exposed the organisms of the rock pool are part of a much smaller body of water than normal. This smaller volume of exposed water is likely to be changed significantly, mostly as a result of heating by the sun (Brehaut, 1982).
Heating of exposed rock pools mean that the organisms within have to cope with considerable abiotic variations There are three major factors which fluctuate in rock ...

Aerosol Spray Cans

... stem down in its housing, uncovering a small a small hole which
leads up through the stem to the nozzle in the button. This allows the product
to be forced up the dip tube by the gas pressure in the can. The nozzle is
shaped to give a spray or a continuous stream.
To produce a fine mist, a propellant is used which mixes with the
product. The two leave the nozzle together and the propellant evaporates a soon
as it reaches the air, breaking the product in to tiny droplets. The same
technique used with a more viscous liquid and a wider nozzle results in a foam.
For a continuous stream of liquid or mor ...

The Formation Of Rocky Shores
Number of Words: 774 / Number of Pages: 3
... shores is separated into distinct zones that reflect the length of time each is exposed. At the highest point on the rocks is the black zone, marked by blue-green algae. This transition area between land and the marine environment is flooded only during the high spring tides. The algae, enclosed in gelatinous sheaths to resist drying, are grazed on by periwinkles, which are protected under tightly sealed, conical shells. Below the black zone lies the white zone, where barnacles are tightly glued to rocks. Living among the barnacles are rock-clinging mollusks called limpets. At low tide, barnacle ...

Human Cloning Isn't As Scary As It Sounds
Number of Words: 1335 / Number of Pages: 5
... determinism—the view
that genes determine everything about us, and that environmental factors or the
random events in human development are utterly insignificant. The overwhelming
consensus among geneticists is that genetic determinism is false.
As geneticists have come to understand the ways in which genes operate, they
have also become aware of the myriad ways in which the environment affects their
"expression." The genetic contribution to the simplest physical traits, such as
height and hair color, is significantly mediated by environmental factors. And
the genetic contribution to the traits ...
