FACTS ABOUT BUTTERFLY

The butterfly is an insect that has four coloured wings. The body is slender and is divided into three parts, the head, the thorax and the abdomen. The head of the butterfly is small and round. It consists of the brain, the sensory organs and the mouth parts. It has a pair of large compound eyes. The butterfly has two antennas which stick out from its head. The antennas serve as smelling organs. They are used to locate food. The mouth is located between the eyes. The proboscis, which looks like a sharp straw, is used to take in food.

The thorax is the middle part of the body. It contains powerful flight muscles and it carries the wings and the legs. The abdomen is tube like in shape and usually consists of six segments. It consists of the heart, the respiratory, reproductive and digestive organs. The butterfly breathes through about ten holes called spiracles. Like all insects, the butterfly lays eggs which hatch into larvae. The larvae are called caterpillars. The caterpillars develops into the pupa. The pupa does not move about. It is usually suspended by a thread to a leaf or tree branch or it may be hidden in the ground. If the pupa survives, it develops into a butterfly after some time.
The butterfly is very useful to humans. It pollinates our flowers and crops. By doing this, it makes it possible for us to have plenty of food to eat.

Tin ore

Tin ore and columbite are two minerals that co-occur in the form of heavy black grains like gunpowder, mixed with sand and gravel. They are deposited in alluvial beds of old river valleys and subsequently buried under layers of soil overburden. The ore is mined by the open cast method. To do this, a powerful machine called a dragline is used to first remove the overburden, and then to scoop out the tin ore which it piles in heaps called a monitor is used to direct a powerful jet of water to this tin wash, which washes it down through a series of sluice boxes. Here, the black, heavy tin grains together with other minerals like columbite, now called tin concentrates, sink to the bottom of the boxes, while the water carries the dirt and sand away. At this stage, the columbite grains are separated from the pure tin concentrates. The concentrates are then sent to factories to be smelted refined and moulded in bars called tin ingots. It is in the form of either ...

Natural soil

Natural soils are influenced by rainfall and temperature,heavy rain causes the soil to become leached. High temperatures increase the rate of decomposition of organic matter in the soil, thereby lowering its humus content. Thus, climatic conditions tend to produce poor soils in the tropics and rich soils in the temperate regions. Besides climate and vegetation, the parent rock material also contributes to the quality of the soil. For example volcanic rocks tend to produce fertile soils. Laterite, a red soil which is a product of leaching, is commonly found in the tropics. It is composed mainly of iron and aluminium compounds,and poor in humus and essential plant nutrients, such as phosphorus, nitrogen and potassium. The black and brown soil of the temperate grasslands are the world's richest soils, with a high mineral and humus content. The light coloured desert soils tend to be very rich in minerals but have a low humus content. Mainly the soils ar...

READING AND UNDERSTANDING

All reading is geared to understanding. There would be no point in reading if we did not understand what we are reading. However there are many different obstacles in the way of easy understanding of a passage. It is your task as a reader to actively seek to break down the barriers to understanding. One block to understanding is caused by references in the passage to things that are outside it. Pronoun are the first examples of words that refer to people and objects. Sometimes, it is easy to follow the reference at other times, it is more difficult. Look at the opening sentence of the passage you've just read that begins this way "She was waiting for us:small, dowdy, dirty..." Who was waiting? Who was the person waiting for? (Perhaps you would also like to know why she was waiting.)Answers to these questions will surely help you to understand and thus follow the reference. The first thing to do is to ask questions like the ones we have just asked and to read t...
