Recycling is a collection,
processing, and reuse of materials that would otherwise be thrown away.
Materials ranging from precious metals to broken glass, from old newspapers to
plastic spoons, can be recycled. The recycling process reclaims the original
material and uses it in new products.
In general, using
recycled materials to make new products costs less and requires less energy
than using new materials. Recycling can also reduce pollution, either by
reducing the demand for high-pollution alternatives or by minimizing the amount
of pollution produced during the manufacturing process.
Paper products
that can be recycled include cardboard containers, wrapping paper, and office
paper. The most commonly recycled paper product is newsprint. In newspaper
recycling, old newspapers are collected and searched for contaminants such as
plastic bags and aluminum foil. The paper goes to a processing plant where it
is mixed with hot water and turned into pulp in a machine that works much like
a big kitchen blender. The pulp is screened and filtered to remove smaller
contaminants. The pulp then goes to a large vat where the ink separates from
the paper fibers and fl oats to the surface. The ink is skimmed off, dried and
reused as ink or burned as boiler fuel. The cleaned pulp is mixed with new wood
fibers to be made into paper again.
Experts estimate
the average office worker generates about 5 kg of wastepaper per month. Every
ton of paper that is recycled saves about 1.4 cu m (about 50 cu ft) of landfill
space. One ton of recycled paper saves 17 pulpwood trees (trees used to produce
paper).

Human body is made
up of countless millions of cells. Food is needed to built up new cells and
replace the worn out cells. However, the food that we take must be changed into
substances that can be carried in the blood to the places where they are
needed. This process is called digestion.
The first digestive process
takes place in the mouth. The food we eat is broken up into small pieces by the
action of teeth, mixed with saliva, a juice secreted by glands in the mouth. Saliva contains digestive juice which
moisten the food, so it can be swallowed easily.
From the mouth, food passes through the esophagus (the food passage) into the
stomach. Here, the food is mixed with the juices secreted by the cells in the
stomach for several hours. Then
the food enters the small intestine. All the time the muscular walls of the
intestine are squeezing, mixing and moving the food onwards.
In a few hours, the food
changes into acids. These are soon absorbed by the villi (microscopic branch
projections from the intestine walls) and passed into the bloodstream.

What is
photosynthesis? Photosynthesis is a food-making process that occurs in green
plants. It is the chief function of leaves. The word photosynthesis means
putting together with light. Green plants use energy from light to combine
carbon dioxide and water to make sugar and other chemical compounds.
How is the light used in
photosynthesis? The light used in photosynthesis is absorbed by a green pigment called
chlorophyll. Each food-making cell in a plant leaf contains chlorophyll in
small bodies called chloroplasts. In chloroplast, light energy causes water
drawn form the soil to split into hydrogen and oxygen.
What are the steps of
photosynthesis process? Let me tell you the process of photosynthesis, in a
series of complicated steps, the hydrogen combines with carbon dioxide from the
air, forming a simple sugar. Oxygen from the water molecules is given off in
the process. From sugar together with nitrogen, sulphur, and phosporus from the
soil-green plants can make starch, fat, protein, vitamins, and other complex
compounds essential for life. Photosynthesis provides the chemical energy that
is needed to produced these compounds.

combines with carbon dioxide from the air …
A. Photosynthesis provides the chemical energy that is needed to produced these
compounds.

Biodiesel is a
clean burning substitute for petroleum based diesel fuel. Biodiesel is made of
vegetable oil.
To make or manufacture
Biodiesel, you must first start with raw materials. The raw materials needed in
the production of Biodiesel are a small amount of methanol and a ready supply
of vegetable product. One of the most common vegetables used in the production
of Biodiesel is corn, although depending on the geographic location of the
manufacturing facility many other plants are used as well (rapeseed, soybeans,
flaxseed, etc.). The first step is to use the raw vegetable product to make
vegetable oil. Vegetable oil by itself will not be what you need to power a
car, from here it has to be processed into Biodiesel.
The process for converting
vegetable oil into Biodiesel is sometimes called ester interchange. To complete
this process the vegetable oil has to be combined with a smaller amount of
methanol and then put in the presence of a small quantity of an alkaline
catalyst (for example, 5% to 1% sodium hydroxide). Vegetable oil is made up of
so-called triglycerides, which is a compound of the trivalent alcohol glycerin
with three fatty acids. The goal of ester interchange is to separate the
glycerin molecule from the three fatty acids and replace it with three methanol
molecules. This process then yields roughly 90% Biodiesel and 10% of a glycerin
byproduct. The glycerin byproduct can be used in a number of other chemical
processes for different industries.

A natural disaster
is a terrible accident, e.g. a great flood, a big fire or an earthquake. It
usually causes great suffering and loss of a large sum of money. The casualties
are injured or died. Some people are homeless and need medical care.
Floods occur when the water of
rivers, lakes, or streams overflow their banks and pour onto the surrounding
land. Floods are caused by many different things. Often heavy rainstorms that
last for a brief can cause a flood. But not all heavy storms are followed by
flooding. If the surrounding land is flat and can absorb the water, no flooding
will occur. If, however, the land is hard and rocky, heavy rain cannot be
absorbed. Where the banks are low, a river may overflow and flood adjacent
lowland.
In many part of the world
flood are caused by tropical storms called hurricanes or typhoons. They bring
destructive winds of high speed, torrents of rain, and flooding. When a flood
occurs, the destruction to surrounding land can be severe. Whole villages and
towns are sometimes swept away by water pouring swiftly over the land. Railroad
track blocked and uprooted from their beds. Highways are washed away.
When a building caught fire,
the firemen pitched in to help battle the blaze. Before the pumps were
invented, people formed bucket brigades to fight fires. Standing side by side,
they formed a human chain from the fire to nearby well or river. They passed
buckets of water from to hand to be poured on the flames.
The damage of the fire did
depend a great deal on where it happened. In the country or a small village,
only a single house might burn down. But in crowded cities, fire often
destroyed whole blocks and neighborhoods before being controlled. (Soal UN
SMA/MA IPA 2011/2012)

The sense of taste is one of a
person’s five senses. We taste with the help of taste-buds in the tongue.
There are four main kinds of
taste: sweet, sour, salty, and bitter. All other tastes are just mixtures of
two or more of these main types.
The surface of the tongue has
more than fifteen thousand taste-buds (or cells). These are connected to the
brain by special nerves which send the so-called ‘tastes messages.
When the tongue comes into contact with food of any kind, the taste-buds will
pick up the taste. The nerves then send a message to the brain. This will make
us aware of the taste. All this happens in just a few seconds.
There are four kinds of
taste-buds, each of which is sensitive to only a particular taste. These four
groups are located in different parts of the tongue.
The taste-buds for salty and
sweet tastes are found round the tip of the tongue and along its sides. Sour
tastes can be picked up only at the sides of the tongue. The taste-buds of the
bitter taste are found at the innermost edge of the tongue. There are
taste-buds at the centre of the tongue.
The senses of smell and sight
can affect taste. The good smell of food increases its taste. Similarly,
attractive colours can make food appear tastier and more delicious. If food
does not smell good or is dull-coloured, it will look tasty and may not taste
good at all.
Very hot or cold sensations can make the taste-buds insensitive. Food that is
too hot or too cold, when placed in the mouth, will have no tastes at all.

A cell phone is a great gadget in
this modern world. What is a cell phone? A cell phone is actually a radio in
certain way. Like a radio, by a cell phone we can communicate to other people
in real time. Million people use cell phone for their communication. Even
nowadays, people use cell phones to communicate in voice, written and data.
Alexander Graham Bell is the person who make great change in the way people
communicate to each other. He invented a telephone in 1876. While wireless
radio was formally known in 18994 presented by Guglielmo Marconi. By these two
technologies, then a cell phone was born. However do you know how actually cell
phones work?
This short explanation on how
a cell phone work is really wonderful. A cell phone or in long term “cellular
telephone’ works by transmitting signals of radio to towers of cellular. The towers
are networked to a central switching station. The connection usually uses wire,
fiber optic-cables, or microwave.
Then the central switching
station which handles calls in certain given area is directed connected to the
wire-based telephone system. Cellulars are pick up by the towers and relayed to
another cellular telephone user or the user of wire-based telephone network.
the towers vary in the capacity and capability to receive signals. Some can
receive the signal from short distance and the others can receive more
distance. However, there are usually more than one tower in certain given area
so that the system can handle the increasing telephone traffic.
