Television Picture Invented Camera
We have at least a television in our home.
television allows us to hear and see events as
soon as they happen. If our grandma's mother or
father see TV, they " ll suprised and say 'This is
diablo's machine!' . We watch TV at least two hour
in a day. HOW WORKS TV When a TV program is
broadcast the sound and picture are sent out
simultaneously by two different radio systems. The
TV camera takes the picture. Camera is the most
important part of the camera. The light from the
object is allowed to f...
Experimental Tube Respiration Rate Temperature
Introduction: Respiration commonly known as the
inhalation and exhaling or breathing has a more
little known definition. This is the definition
that involves the cellular level of eukaryotic
cells. Cellular respiration may best be described
by the following equation: C 6 h 1206+602-6 CO 2+6
H 20+36 ATP. ATP that is the energy needed for a
cell to function as part of cellular respiration.
ATP is needed to power the cell processes. If
cells are denied energy they will die. The second
law of therm...
Plasmid Extraction Five Minutes
Introduction Chitobiase, from Vibrio harvey i, is
a membrane bound lipoprotein involved in the
degradation of chitin. Chitobiase is similar to
and may share a common ancestry to the a-chain of
human b-hexes-aminidase. Chitobiase is encoded by
chb. In this experiment, a restriction map for
restriction enzymes Eco R 1, Pst 1 and Hind III
using Southern hybridization and restriction
analysis of pRSG 192. pRSG 192 is a recombinant
plasmid derived from the chb gene and pUC 19, a 2.

Beet Lab Test Tube
MATERIAL AND METHODS Stability of cell membrane
using pHF or the lab experiment for testing the
stability of beet cell membranes using pH, many
materials were used as follows. Obtaining a beet
we punch out cores, using a cork borer. After
washing the cores we put each one inside a
separate test tube, and added a different pH
solution in each one. After 3 minutes in these
exposure solutions, we took the beet out with a
dissecting needle. Then transferred each beet to
a separate test tube contain...
Fermentation Test Tube
Planning PROBLEM TO BE INVESTIGATED Yeast enzyme
specificity: Specificity of Brewers and Bakers
yeast enzymes to different sugars (being
monosaccharides) HYPOTHESIS I predict Bakers yeast
to have a different enzyme specificity compared to
Brewers yeast where more CO 2 is produced at 37 0
C. BACKGROUND KNOWLEDGE Fermentation is the
breakdown of sugars by bacteria and yeast using a
method of respiration without oxygen (anaerobic
respiration). It involves a culture of yeast and a
solution of sugar,...
Nuclear Reactors Fuel Rods
Nuclear Reactors Using a nuclear reactor is an
efficient way to produce large amounts of
electricity. Nuclear reactors are used to provide
power to a neighboring town or city. In a nuclear
reactor, water is heated using nuclear energy to
the point that it boils and the steam collects
around a collection of spinning blades, called a
steam turbine. The pressure from the steam turns
these blades, which are connected to a dynamo, or
generator. The generator is activated and produces
Test Tube Experimental Water Tubes
Materials and Methods The first experiment
involved examining the effect of temperature on
aerobic respiration of germinated pea seeds. The
students testing the effect of temperature, will
be divided into two groups. The first group is
Student Pair A. They will test the effect of 10 C,
20 C and 30 C temperatures on pea respiration
rate. The second group is Student Pair B. They
will test the effect of 40 C and 70 C temperatures
on pea respiration rate. For both groups, the
first procedure calls ...
Glass Tube Flow Water Rate
Hypothesis This investigation starts by
investigating the effect of the length of glass
tube on the rate of flow of water out of it. The
volume per second of the water flowing out of the
tube (rate), is determined by the forces acting.
The pressure force pushes the fluid through the
pipe against the resistance of the viscous force.
Therefore I would expect a longer glass tube to
create more force opposing the movement of water
and therefore produce a slower rate. In this
experiment I expect to f...
Test Tube Enzyme Catechol Water
Lab Report 1 Principles of Biology 1 (BIOL 100)
Fall 2001 Gerard Chretien Living cells perform a
multitude of chemical reactions very rapidly
because of the participation of enzymes. Enzymes
are biological catalysts, compounds that speed up
a chemical reaction without being used up or
altered in the reaction. The material with which
the catalysts reacts, called the substrate, is
modified during the reaction to form a new
product. But because the enzyme itself emerges
from the reaction unchanged ...

Zinc And Hydrochloric Acid
Zinc and Hydrochloric-Acid Written By Kahlil
ZioneDate: 02/02/05 Abstract: We observed the
reaction between zinc and hydrochloric acid and
recorded it in a table and learned wether the
percentage of zinc is effected by the amounts of
both substances added to the solution.
Introduction The purpose of this experiment is to
determine if the amount of zinc and hydrochloric
acid will effect the percentage of the zinc in the
out coming solution. We are reacting zinc metal
with hydrochloric acid to pro...

Fireworks Tube Make Glue
Every year, America celebrates many holidays with
fireworks. One of the most popular selections is a
Roman Candle. If you want to try to make this at
home, common pyrotechnics stores have all the
supplies you would need. Just think of the "oohs"
and "ahhhh's" when you light off your homemade
fireworks at home. First of all, you need a
sturdy, good tube. The tube should be cylindrical
and should be at least 3/32 of an inch thick. The
opening at the top of your tube should have a 5/8
Test Tube Substance Litmus Paper
What is in each test-tube? What proof do I have of
this? Test-tube A: Test-tube A had water in it. I
can base this on the fact that it was a neutral,
reacting neither to red or blue litmus paper.
Phenolphthalein also did not react to this
substance. The pH value was 7, neutral, also
adding to the proof that this substance was water,
because water is neutral. The substance was clear
and odorless, and all of these reactions combined
led me to my conclusion of substance A being
water. Test-tube B:...
Gel Filtration Chromatography Fractionation Range
This lab s topic was Gel Filtration
Chromatography. Chromatography is a technique used
to separate molecules on the basis of differences
in size, shape, mass, charge, solubility and
absorption properties. A specific kind of
chromatography is gel filtration. This technique
separates molecules on the basis of their size.
This procedure is performed by passing molecules
down a solution containing beads made of a
polysaccharide or polyacrylamide gel with
semi-uniform pores. All of the beads have th...
Communication Antenna Inches Outer
A dipole is a balanced antenna and should not be
fed directly with coaxial cable. Doing so would
cause the outer conductor of the coaxial line to
act as part f the antenna, and a large amount of
signal would be radiated or received by he outer
conductor. For casual reception his may not matter
much, but the directional radiation pattern of the
antenna is destroyed and reception / transmission
results are no longer predictable. In order to
derive a balanced feed for the dipole some sort of

Investigating Hard And Soft Water
INTRODUCTION: Water that contains calcium and
magnesium ions is called "hard water" because
calcium and magnesium ions can combine with other
ions and compounds to leave a hard scale on the
surfaces they touch. Hard water may be a
troublesome in household water supplies.
Fortunately, there are simple solutions to hard
water problems. Hard water can be softened by the
removal of metallic ions responsible for the
hardness. This is known as water softening.
Softened water is desirable in the bathtu...
