Constitution can be defined as a body/system of fundamental rights and regulations according to which a nation, organisation or state is governed. These rules and regulations clearly state the various rights and duties of a citizen and also the powers and functions of the government.

A computer virus is a malicious software program loaded onto a user's computer without the user's knowledge and performs malicious actions. It can self-replicate, inserting itself onto other programs or files, infecting them in the process. Not all computer viruses are destructive though. In the early, pre-internet days, viruses often spread from computer to computer via infected floppy disks. The SCA virus, for instance, spread amongst Amiga users on disks with pirated software. It was mostly harmless, but at one point as many as 40% of Amiga users were infected. Today, viruses spread via the internet.

Sugar is the one which forms the backbone of the DNA molecule. It is also called deoxyribose. The nitrogenous bases of the opposite strands form hydrogen bonds, forming a ladder-like structure.

Deoxyribonucleic acid; a nucleic acid that consists of two long chains of nucleotides twisted together into a double helix and joined by hydrogen bonds between complementary bases adenine and thymine or cytosine and guanine; it carries the cell's genetic information and hereditary characteristics via its nucleotides. Three major forms of DNA are double stranded and connected by interactions between complementary base pairs. These are terms A-form, B-form,and Z-form DNA.

• Veins –

1. Veins carry blood rich in carbon di oxide from all the cells of the body to the heart.
2. The pressure exerted by the walls of the veins is less and have thin walls.
3. Valves present in the veins ensure that the blood flows only towards the heart.

Dear brother,

                      It is quite shocking that now in the 21st century when people talk about liberty and right and are educated still now exercise such absurd activities on the school bus.

                      I would like to advise you with some of the treatments that can get you rid of these activities. Firstly, you do not need to give your mind stress regarding what they are saying to you while bullying. They are not very important. Secondly, do what you think is right, but always be kind towards each and every one.

Thirdly, as they are not giving you respect try to make them feel how and what respect means giving them respect.

Never get afraid of sitting on the seat they take. This advice tells you to take the help of your teachers and parents.

                I hope my advices will help you and you will overcome the situation and it is all pleasant to hear that you are all well in London.

Yours lovingly

Name(Your Sister)

Oesophagus

• Oesophagus is also called the food pipe.
• It runs along the neck and the chest.
• The food from mouth after swallowing passes into oesophagus and is pushed down to stomach by a special movement called peristalsis.
• This peristaltic movement takes place through out the alimentary canal which pushes the food in downwards direction.
• At some times the stomach is not ready to take up food causing vomiting, where food is expelled out from the oesophagus to mouth by reverse peristaltic movement.

Ruminants are grass eating animals like the cow, ox, buffalo and sheep swallow the food without chewing. After feeding, they bring the food from the stomach back into the mouth and chew it leisurely. This process is called rumination and such animals are called as ruminants. Many different species of ruminant animals are found around the world. Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four.

The process by which green plants use sunlight to make food from carbon dioxide and water is called photosynthesis. The synthesis of food in plants occurs in leaves due to the presence of green pigment called chlorophyll. It is responsible for the absorption of light energy from the sun. The solar energy is captured by the leaves and stored in the plant in the form of food. During the process oxygen is released and a simple carbohydrate is produced which is called as glucose. The glucose is than converted into complex carbohydrate called as starch which is stored in various parts of plants. The plants also make oils as food, proteins as food and vitamins as food.

Dignity is defined as the personal quality of being worthy of honor. An example of dignity is the respect paid to an elder member in the family. If someone has dignity, it means they are worthy of respect. ... Someone with dignity carries herself well. If you lose an election, and you say nasty things about your opponent and try to undermine her, you are acting without dignity.

Country leading in silk production is China. In 2005 China accounted for 74% of the global silk production. India occupies second position after China. Rearing of silkworms for silk production is called sericulture. Silk Industry provides employment to 7.9 million people in India, and 20,000 weaving families in Thailand. China is the world's single biggest producer and chief supplier of silk to the world markets.

Digestion of food in human beings begins in the mouth. The mouth cavity contains teeth, tongue and salivary glands. The teeth cut the food into small pieces, chew and grind it. This is called physical digestion. Salivary glands produce saliva which mixes with the food. This involves chemical digestion of food. The saliva contains an enzyme called salivary amylase which digests the starch and converts it into maltose sugar. Mouth opens into a small funnel shaped area called pharynx which leads to a long tube called oesophagus. It carries the food down into the stomach. The wall of oesophagus is muscular. When the slightly digested food enters the food pipe, the walls of the oesophagus starts contraction and expansion movements called peristaltic movements which push the food into the stomach. Digestion does not take place in the oesophagus.
The glands present on the walls of the stomach secrete gastric juice that contains hydrochloric acid, the enzyme pepsin and mucus. A small amount of gastric lipase is also present that breaks down the fats present in the food. Gastric juice is acidic due to the presence of HCl which is necessary for the pepsin to become active and converts the proteins into peptones. The mucus protects the stomach walls from HCl. From the stomach, the partially digested food goes into the small intestine through sphincter muscle. Small intestine is divided into two parts: Duodenum and Ileum.
Duodenum receives the secretions of two glands, liver and pancreas through a common duct. Liver secretes bile which is alkaline and contains salts to emulsify the fats (or lipids). The bile secreted by the liver is stored in the gall bladder. Pancreas secretes pancreatic juice which contains trypsin, lipase and pancreatic amylase. Trypsin digests the proteins, lipase emulsifies the fats and pancreatic amylase breaks down the starch. Thus, small intestine is the site of complete digestion of carbohydrates, proteins and fats. The walls of ileum secrete succus entericus which completes the digestion process.
