WHY DO WE TAKE ANTIBIOTICS?

Antibiotics are chemicals. When these chemicals are put into the body they kill or stop the growth of certain kinds of germs.

In other words they help your body to fight off disease. Many modern antibiotics are made from microbes, which are tiny living things. For example, bacteria and moulds are microbes.

The microbes used in making antibiotics are chosen for their ability to produce chemicals that wage war on the microbes of disease. In simple terms this means that man is taking advantage of the struggle that goes on in nature among microbes.

Antibiotics are very effective at curing diseases and work in various ways.

One antibiotic may act in different ways against different germs.

It may kill the germs in one case and in another only weaken them and let the body's natural defences take over.

WHY IS OUR BLOOD RED?

Blood: The blood which flows through our body contains many different materials and cells. Each part of the blood has its own special job to do. Plasma: The liquid part of our blood is called the plasma and makes up a little more than half the blood. It is light yellow in colour and thicker than water as many substances are dissolved in it. These substances are protein, antibodies that fight disease, fibrinogen that helps the blood to clot, carbohydrates, fats and salts, in addition to the blood cells themselves RBC: The red cells (also called red blood corpuscles) give the blood its colour. There are so many of them in the blood that it makes it all look red. There are about 35 trillion of these tiny, round, flat discs moving around in your body all at once. As the young red cell grows and takes on adult form in the marrow, it loses its nucleus and builds up more and more haemoglobin. Haemoglobin: Haemoglobin is the red pigment, or colour. ...

WHY DOES MICKEY MOUSE HAVE FOUR FINGERS?

Why does Mickey Mouse have three fingers and one thumb on each hand? In fact, why is virtually every cartoon animal's hand beset with one missing digit? Conversations with many cartoonists, animators and Disney employees confirm what we were at first sceptical about. Mickey Mouse has four fingers because it is convenient for the artists and animators who have drawn him. In the early cartoons, each frame was hand-drawn by an animator painstaking and tedious work. No part of the human anatomy is harder to draw than a hand , and it is particularly difficult to draw distinct fingers without making the whole hand look disproportionately large . The artists who drew Mickey were more than happy to go along with any conceit that saved them some work. So in Disney and most other cartoons, the animals sport a thumb and three fingers, while humans, such as Snow White and Cinderella, are spared the amputation. And before you ask - no, we don't know f...
