The following text is for questions 15 to 18.

All human beings eat food and use the chemical energy in it, as do all other animals. Perhaps you wonder where all that chemical energy comes from. Why doesn't the food all get used up?

The answer is that new food is being grown as fast as old food is used. It is the green plants that form the new food. Animals either eat the plants or eat other animals that have eaten plants.

The green substance of plants is chlorophyll. Chlorophyll can absorb sunlight. When it does so, it changes the energy of the sun into chemical energy. The chemical energy present in sunlit chlorophyll is used to combine dioxide in the air with water from the soil. Starch and other complicated compounds are formed. These are high in chemical energy obtained from the sunlit chlorophyll.

They make up the food on which mankind and all other animals live. In the process of forming this food, some oxygen atoms are left over. These are given off into the air by the plants. The whole process is called photosynthesis.

Thus, plants use sunlight to form food and oxygen to form carbon dioxide and water again. Plants change the sun’s energy into chemical energy. And animals change the animal energy into kinetic and heat energy.

The following text is for questions 19 to 21.

Silkworms live for only two or three days after laying eggs. About 36,000 to 50,000 eggs are laid, and these are carefully stored at the silkworm farm until they are ready to hatch. The eggs hatch into caterpillars, which feed on mulberry leaves. Soon, the caterpillars are ready to spin their cocoons.

Not all caterpillars can spin silk cocoons. Only the caterpillars of a silkworm moth known as ‘Bombyx Marie can do the such spinning. This caterpillar has special glands which secrete liquid silk through its lower lip. The liquid produced later hardens to form tine strands.

The caterpillar makes its cocoons using these strands. The threads on the outside of the cocoon are rough, while those inside are soft and smooth.

Some fully-spun cocoons are heated. This kills the pupa inside. The cocoons are then put into hot water to loosen the fine threads. Finally, these threads are reeled off the cocoons.

The length of unbroken thread produced by a single cocoon measures about one-and-a-half kilometers. Being twisted together several of these threads make single woven materials.

The Sense of Taste

The sense of taste is one of a persons five senses. We taste with the help of taste-buds in the tongue. There are four mains’ 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 onw 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 own 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 maxe the taste-buds insensitive. Food that is too hot or too cold, when placed in the mouth, will have no tastes at all.

Have you ever wondered how people get chocolate from? In this article we’ll enter the amazing world of chocolate so you can understand exactly what you’re eating.

Chocolate starts with a tree called the cacao tree. This tree grows in equatorial regions, especially in places such as South America, Africa, and Indonesia. The cacao tree produces a fruit about the size of a small pine apple. Inside the fruit are the tree’s seeds, also known as cocoa beans.

The beans are fermented for about a week, dried in the sun and then shipped to the chocolate maker. The chocolate maker starts by roasting the beans to bring out the flavour. Different beans from different places have different qualities and flavor, so they are often sorted and blended to produce a distinctive mix. Next, the roasted beans are winnowed. Winnowing removes the meat nib of the cacao bean from its shell. Then, the nibs are blended. The blended nibs are ground to make it a liquid. The liquid is called chocolate liquor. It tastes bitter. All seeds contain some amount of fat, and cacao beans are not different. However, cacao beans are half fat, which is why the ground nibs form liquid. It’s pure bitter chocolate.

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.
