Connective Tissue Lactic Acid
1,736 words
The immediate source of energy for muscular
contraction is the high-energy phosphate compound
called adenosine triphosphate (ATP). Although ATP
is not the only energy-carrying molecule in the
cell, it is the most important one, and without
sufficient amounts of ATP most cells die quickly.
The three main parts of an ATP molecule are: an
adenine portion, a ribose portion, and three
phosphates linked together. The formation of ATP
occurs by combining adenosine diphosphate (ADP)
and inorganic phosph...

Natural Gas Diesel Fuel
733 words
We have known for a long time that eventually our
oil deposits will dry up, and it would be helpful
at that time if we had some kind of alternative
fuel to power all of the machines that we use.
Over the past two decades more oil has been pumped
than has been found in the world. For this reason
scientists have been looking to potential
alternative fuels for the future. One of these
alternative fuels may come in the form of natural
gas. Natural gas has been found to be more
plentiful than oil, an...

Acid Mine Drainage Causes Effects And Solutions
1,484 words
For hundreds, even thousands of years, human
beings have mined for metals and stones, and with
the advent of greater technology as well as
greater needs, the demands for these resources
continue to grow. While these resources benefit
our lives in many ways, the effects of mining can
be detrimental, and one such effect is the topic
of this essay, acid mine drainage (A. M. D. ). The
causes of A. M. D. will be discussed, along with
some of the physical and biological problems
associated with it. So...

Introduction What is the oceans role in climate?
The oceans play a vital and pivotal role in the
distribution of life sustaining water throughout
our planet. 86 % of the evaporation that occurs on
earth is over the oceans. The oceans are the
planets largest reservoir of water transferring
huge amounts of water around the hydrological
cycle. In fact the oceans dominate the
hydrological cycle, for they contain 97 % of the
global water inventory. The hydrological cycle can
be disrupted by changes i...

Rapid Expansion Blue Green

Up until 1947, it was believed that the Cambrian
Explosion marked the first true abundance of
multicellular life. However, this was discovered
to be untrue after Sir Douglas Mawson and R. C.
Spring mistakenly came across numerous "fossil
jellyfish" in the Ediacaran Hills while observing
what was originally believed to be sandstones
belonging to the lowest strata of the Cambrian. At
first, these finding were dismissed as "fortuitous
inorganic markings. " (AAS Biographical Memoirs. )

Hydrogen And Oxygen Combustion Engines

Hard to believe that the simplest atom in the
universe is used in the making of the most
destructive weapon known to man isnt it? Well so
is the fact that it will soon (we hope) become the
replacement for petroleum-based fuels, and just
about every other form of fuel too. One electron
orbiting one proton is all that hydrogen is, and
it is mankind's future. It is easy to manufacture,
(although the government says otherwise, ) safe
and easy to store, and has only one by-product
water. The way that...

Purpose - The purpose of this lab is to use a
chemical titration to measure and them calculate
the rate of conversion of hydrogen peroxide (H 2 O
2) to water and oxygen gas using the enzyme
catalase. Hypothesis - The rate of
enzymatically-catalyzed reactions can be
determined by taking time reactions at different
time intervals. When the rates are plotted on a
graph, the rate of the reaction is the slope of
the linear portion of the curve. To determine a
rate, any two points on the straight-line...

disorder that affects red blood cells. People with
sickle cell have red blood cells that have mostly
hemoglobin's, Sometimes these red blood cells
become sickle-shaped or crescent shaped and have
trouble going through small blood vessels. When
sickle-shaped cells block small blood vessels,
less blood can get to that part of the body.
Tissue that does not get a normal blood flow
eventually becomes damaged. This is what causes

Air Pressure Internal Pressure
505 words
It s Not Suction Purpose: The purpose of this
experiment is to show the effects that air
pressure has on a liquid and the necessity of
oxygen for combustion. Background: When a
substance burns it is known as combustion. For
combustion to occur oxygen must be present. Once a
flame has used all of its oxygen supply it will
die, this marks the end of combustion. Combustion
stops occurring when the flame supplying the
energy to a system goes out or the substance is
completely used up. In a closed sy...

Carbon Dioxide And Water Green Plants

Photosynthesis is the Photosynthesis
PHOTOSYNTHESIS Photosynthesis is the process by
which green plants and certain other organisms use
the energy of light to convert carbon dioxide and
water into the simple sugar glucose. In so doing,
photosynthesis provides the basic energy source
for almost all organisms. Oxygen is extremely
important to photosynthesis, which most organisms
depend on. Photosynthesis occurs in green plants,
seaweeds, algae, and certain bacteria. Chlorophyll

Carbon Dioxide Ozone Layer
1,519 words
In environmental science the green house effect is
a common term for the role water vapor; carbon
dioxide and ozone play in keeping the earths
surface warmer than it would normally be. The
atmosphere is primarily transparent to infrared
radiation from the sun, which is mostly absorbed
by the earths surface. The earth being much cooler
than the sun, remits radiation most strongly at
infrared wavelengths. Water vapor, carbon dioxide
and ozone then absorb much of this radiation and
remit a large pr...
