World War Ii Vacuum Tubes
1,137 words
Since the beginning of the Industrial Revolution,
people wanted and needed an easier way of
calculating and measuring. Through the dreams of
Charles Babbage, the computer was born. These new
machines could do any regular math more than twice
as fast as any human. Sadly, these ideas were not
appreciated until almost one hundred years later.
In the 1950 's, the idea of computers was brought
up again. This is when people finally started
crediting Babbage's work. The technology available
now made it...

Test Tube Degrees Celsius

Enzyme Action: Testing Catalase Activity Enzymes
are proteins that serve as catalysts and
accelerate chemical reactions in living organisms.
Enzymes accomplish this by lowering the energy of
activation of the organism it is acting upon,
however enzymes will only lower the energy of
activation for specific organisms, reducing
chaotic chemical reactions. The reaction is
carried out in its entirety in the active site of
the enzyme. The substrate (organism acted upon),
binds itself into the active s...

Petri Dishes Bacteria Cells
1,566 words
In this lab we observed the growth of bacteria in
a conjugation and transformation experiment. We
expected the mating plate of the conjunction to
grow and the bacteria on the transformation plates
to grow also. We also practiced using aseptic
techniques to clean the lab benches and to keep
the bacteria from being contaminated from outside
bacteria. This lab will take a total of 2 days
because of the observations that need to be made.
The parts of this paper will explain the procedure
and the obs...

Lab Report 1: Separation of Proteins
Abstract/Summary: "Proteins account for more than
50 % of the dry weight of most cells, and they are
instrumental in almost everything organisms do"
(Campbell, 1999). The significance of proteins to
the continuation of our biological systems is
undeniable, and a study of how to quantify
proteins seems an appropriate introduction to our
studies of biology. In order to study proteins we
must first know how to separate then quantify the
amount using basic princi...

Experiments to Determine the Effect of Acids &
Bases on Different Indicators and the pH of Common
Cleaning Agents The aim of the first set of
experiments is to find out and record the colour
changes that are observed after a certain
indicator is mixed with acids and bases to form a
colour reaction. Once the selected indicator has
been mixed with a acid that is both weak and
strong and a base / alkali that is both weak and
strong we are to record the colour and choose
another indicator. The purpo...

Stimulating Factors Or Triggers Factors Or Triggers Asthma
725 words
Asthma is a condition of the bronchial tubes
characterized by episodes of constriction and
increased mucous production. A person with asthma
has bronchial tubes that are super sensitive to
various stimuli, or triggers, that can produce
asthma symptom. In other words, asthmatics have
special sensitivity that causes their lung tissue
to react far more than is should to various
stimulating factors or triggers. For this reason,
people with asthma are said to have "twitchy
airways. " Some symptoms th...

Barco 1000, 1001, 1500 and 1600. These are a
series of 9 " analog convergence projectors that
Barco came out with from about 1989 to 1993. All
very similar to the Barco 600 chassis, but used 9
" Sony ES focus tubes, called the SD- 146 A. A
great picture when properly set up, but Barco
drove these tubes quite hard, and sudden tube
failures were common. These tubes are hard to find
on the used market, and are insanely expensive if
purchased new. 64 Khz scan rate, 1000 to 1500

Biology Research In Vitro Fertilization
2,054 words
In Vitro Fertilization (IVF), is the procedure
whereby human babies are conceived, not in the
womb but in a test tube or a Petri dish. This
procedure has become one of the greatest
developments in the world of medical technology.
In Vitro Fertilization has given infertile couples
the chance to conceive and bear a child from a
full term of pregnancy. Without this procedure,
their infertility would render them childless.
There are many aspects of the IVF program that
have been both praised and cri...

... ting smaller fragments that travel longer
distances than the single cut or uncut, during
electrophoresis. Which in turn proves that segment
sizes are proportional to distance migrated. On a
standard curve, the distance migrated is used in
order to extrapolate the size of the DNA (base
pairs). For an undigested or uncut p KAN plasmid
it is expected that one fragment will be shown,
unless the plasmid has been nicked and then will
therefore show three. The size of this fragment
should be close ...

Rate Of Reaction Bunsen Burner
2,301 words
For this investigation I am going to investigate
the effect of the concentration of an enzyme, in
this case Amylase, on the time taken for the
enzyme to fully breakdown the substrate, which in
this case is starch. The reason why these two
enzymes have to be used is because each enzyme is
designed specifically to break down only one
substrate as each enzyme is made of a protein that
causes it to be a specific shape, in this case the
enzyme Amylase can only break down starch to
dextrin. I am going...

ampicillin resistant DNA is introduced into the E.
coli bacteria, through the uptake of this DNA the
bacteria will receive the resistant gene that will
permit the bacteria to grow freely in the presence
of ampicillin. Experimental Design: By observing
the E. coli bacteria one can study how it reacts
when a foreign gene such as the ampicillin
