What are writing is important?
Writing is one of the most important
forms of communication. Man first learnt to communicate through sound and
gesture. However, he soon felt the need to communicate through other means. Writing
was one of them. Writing was invented and developed in all the ancient culture.
The need to maintain records of transaction important events taking place in
the society led to and carving on rocks to convey through and ideas to other. These
rocks painting and carving are called petroglyphs. The carving and painting
were done with the help of stone tools by prehistoric people. The Sumerians were
the first to invent a script that later developed into an organised system of
writing. This script is known as the Cuneiform. It was developed as a
pictograph that had 600 signs.
Why do animals have tail?
Most of the animals walk on all four limbs. They do not have any limbs free to perform other functions. Therefore, the tails of the animals carry out many of these functions.

Early humans also had tails but it slowly disappeared as they evolved and stooped using it.
Why do
stars appear to twinkle ?
Stars are extremely large gaseous bodies
found in the universe. They emit enormous amounts of light and other forms of
energy. This enormous amounts of energy comes from the nuclear fusion
reaction taking place in them. The nearest star to our earth is the sun. Billion of stars can be observed in the night sky. When
observed they appear to twinkle. The light
emitted by the stars has to pass through the atmosphere before it reaches us. While
passing through the various layers the light is bent. This makes the light to
flicker. Thus , for scientific observation scientists observe stars from the
top of a mountain. This is because as we go high the air becomes thin and it
cause the twinkling effects to reduce.
How does heat t0 transfer take
place?
Heat is a form of that can be transferred from one body to another. Heat transfer from one body to another take place when a temperature difference exists between the two objects. Temperature is the degree of hotness or coldness of body. Heat transfer can take place in three different ways: convention, conduction and radiation. Conduction of heat take place when the two objects are in contact with each other. Heat transfer, within the body, also take place due to this method. In convention, the actual transfer of the heat take place when the heated molecules of the substances move actually from one place to another. No actual contact between the bodies is required for heat transfer by this process. Radiation is the transfer of heat through electromagnetic waves. No medium or contact is necessary for heat transfer of take place through radiation. The best example for this is the heat energy that we receive from the sun.
Very important Why circulation
necessary in our body
The circulatory system regulates the
flow of blood throughout the body. It consists of the heart, blood vessels and
blood. The circulatory system transport oxygen and nutrients to the tissue and
cells of the body. It also collect the waste products from the cells. The continuous
circulation of the blood maintains the temperature balance of the body. The blood
also has substance that protects the body
from infection and diseases. The circulatory system is divided into three parts
of ---pulmonary, coronary and systemic. The pulmonary circulation is the
movement of blood from heart to lungs and from back to heart.
Coronary circulation supplies blood to the heart itself. Systemic circulation
is supply of heart itself. The heart to the various parts of the body, except lungs, and back.

Why do star “fall”
The stars do not fall from the sky. In the olden days, the meteoroids were called ‘falling stars’. Meteoroids are small piece of metallic debris. Some of them are very small but large meteoroid have also been found. Some of these meteoroids, which enter the Earth atmosphere, burn up. This is due to the friction that they encounter with the Earth’s atmosphere are known as meteors. Those meteors that do not burn up fall to the Earth as rocks and dust. These are known as meteorites. Meteoroids appear as bright streaks of light with a glowing trail and are known as ‘shooting stars’ or ‘falling star’. Meteorites are mostly made up of iron and nikel.
Why is blood red in colour?
Blood that flows through our body carries oxygen and nutrients to all parts of our body. It also carries carbon dioxide and waste from the cell. Blood fights infection and helps in maintaining the body temperature. Blood is made of plasma, red blood corpuscles (RBC), white blood corpuscles (WBC) and platelets. The plasma is a clear watery liquid that contain dissolved salts, nutrients, gases, albumin, fibrogen, wastes and hormone. Platelets are small colourless blood cells that help in clotting the blood . WBCs helps the body to fight infection and disease. The blood gets its colour from the RBCs, the main component of blood. There are almost 20-30 trillion RBCs in the blood. The RBC contains the protein haemoglobin that transport oxygen from the lungs to all parts of the body. The haemoglobin also are carries carbon dioxide from the cells to the lungs.
