1. Energy releasing food : Carbohydrates and lipids 

2. Body building food : Proteins 

3. Protective Food : Vitamin and minerals

Food can be defined as a substance which nourishes the body.

Carbohydrates are naturally occurring macro nutrient which form a major component of living organism. They include sugars, starch and cellulose. These are the compounds made of carbon, hydrogen and oxygen.

Food contains nourishing substance called nutrients. Nutrients are the ultimate nourishing chemicals found in food.

The sources of carbohydrates are cereals, sugar, jiggers potatoes etc.

Good nutrition is one of the major key’s to a healthy life. We can improve our family health by resorting to a balanced diet. We should eat food that contains vitamins and minerals. This includes fruits, vegetables, whole grains, dairy products and some such sources of protein.

Nutritional signification of carbohydrates. 

1. Carbohydrates help in the regulation of sugar in the blood stream. 

2. Carbohydrates acts as a shield and protects muscles. 

3. Fibers present in the carbohydrates such as cellulose keep body movement smooth. 

4. Carbohydrates oxidized in the mitochondrial to release energy during cellular respiration and the energy is used by cells for various metabolic activities.

1. Calcium help to build bones and teeth 

2. It help to proper functioning of muscles heart and nerves, relieves pain and cramps 

3. It help in clotting of blood.

Balanced diet should contain variety of nutrients like carbohydrates, proteins, fats, vitamins minerals and dietary fiber in right quantity according to age, sex, size of the body and activity to maintain normal health.

Take 5 ml of the give sample in a test tube add small amount of ethyl alcohol to it. Shake well. Heat the test tube carefully on water bath, when the sample dissolves in alcohol filter or dilute until you get a clear liquid take a small quantity of tap water in another test tube, pour the solution prepared above gently into the test tube. If a whitish suspension is formed then the given sample is a lipid.

1. Water constitutes about 55-75 percent of our body mass. 

2. It helps to maintain the health of every cell in the body 

3. It keeps the blood thin enough to plow thorough blood. 

4. It helps to eliminate the water and excess materials 

5. Water regulates body temperature through sweating. 

6. Water helps digestion an prevents constipation. 

7. It helps to carry nutrients and oxygen to the cells.

Nutritional importance of proteins:

1. Some proteins are involved in structural support and some other are involved in bodily movement. 

2. Proteins assist on building up defense against germs 

3. Enzymes which facilitate the biochemical reaction are also proteins. 

4. Hormones are also proteins 

5. Hemoglobin which is present in the blood is also protein. 

6. The proteins like keratin and collagen which are fibrous and tough provide support to tendons and ligaments.

Despite having enough food some people suffer from nutritional deficiencies since they do not take a complete balanced diet which provides all the nutrients to our body in right proportion

The sources of carbohydrates are cereals, sugar, jigger potatoes etc.

Oils and fats are the main food items. Butter, cheese, cream, fatty metals are the food items which gives lipids.

(i) all living organisms are composed of cells. 

(ii) all cells arise from pre-existing cells.

Rough Endoplasmic Reticulum (RER) : 

• Ribosomes attached to outer surface. 

• Involved in protein synthesis and secretion.

Smooth Endoplasmic Reticulum (SER) : 

• Lack ribosomes. 

• Site for synthesis of lipid.

i. Social problems – Vast area of land get submerged under water so many people become homeless. It also leads to unequal distribution of water. People close to the source will get enough water for agriculture whereas those far from the source cannot get sufficient water. 

ii. Environmental problems – Large-scale deforestation, loss of flora and fauna of that particular area, displacement of large number of people living in that area etc.

Social problems:

(i) Many people are rendered homeless. 

(ii) Displacement of large number of tribals without due compensation. 

(iii) Migration into the cities for settlements. 

Environmental problems : 

(i) Deforestation / loss of biodiversity 

(ii) soil erosion / ecological imbalance.

The three types of problems that arise because of the construction of big dams are : 

(i) Environmental problems : Construction of dams across rivers leads to deforestation, which results in the loss of biodiversity. This disturbs the natural ecosystem. 

Solution : We should plant more and more trees. 

(ii) Social problems : Construction of darns involves the building of large reservoirs. In some cases, constructing a reservoir may result in the flooding of nearby towns and villages. A large number of people get displaced as a direct consequence of the construction of reservoirs. In such cases, the government has to rehabilitate the people living in these areas, which, in itself, is a huge task.

Solution : The government should first relocate the people to a safer place where they can continue with their daily work. If, in case, the life of the people gets affected, the government should provide proper compensation to those people. 

(iii) Economic problems : Construction of dams requires a huge amount of monetary investments. 

Solution : Construction of dams can be profitable if they are used for the generation of electricity.

(a) The advantages of constructing dams across the rivers are: 

1. Water from a dam is used for irrigation in fields through a network of canals. 

2. Water from a dam is supplied to the people in towns and cities through pipelines after suitable treatment. 

3. The falling water from the dam is used for generating electricity. 

(b) The problems associated with the construction of dams are: 

1. Social Problems: Due to the constriction of high rise dams, a large number of human settlements are submerged in the water of large reservoir formed by the dam and many people are rendered homeless. This creates a social problem. 

2. Environmental Problems: The construction of high rise dams on the rivers contributes to deforestation and loss of biodiversity. This is because of a vast variety of flora and fauna (plants and animals) get submerged in the water of large reservoir formed by the dam and disturb the ecological balance. 

3. Economic Problems: Some people say that the construction of high rise dams involves the spending of huge amount of public money without the generation of proportionate benefits.

All three i.e. social, economic, environmental reasons are main opposition for contruction of large dams.

An electromagnet is a solenoid coil that attains magnetism due to a flow of current. It works on the principle of magnetic effect of current.

(i) By suspending magnetised bar and identify its north and south poles.

(ii) By finding the polarity of electromagnet using the property -like poles repel.

The vegetative part of plant, root, stem, leaf or budgets detached from the parent body and grows into an independent daughter plant by mitotic division. The daughter plants are genetically similar to the parent plant.

Convex and concave lens can be distinguished by touching them. If the curved surface is bulging outwards then it's convex lens and if the curved surface is curved inwards then it's concave lens.

Another way to differentiate between the two lenses is, by bringing some written matter just in front of both the lenses one by one and, look for its image from the other side of the lenses. 

(i) If the image of the written matter formed by the lens is virtual, erect and enlarged, then it is a convex lens. 

(ii) If the image formed is virtual, erect but diminished, then it is a concave lens.

We can distinguish between a plane mirror, a concave mirror and a convex mirror by bringing our face close to each mirror, turn by turn. If the image is of the same size as our face, it is a plane mirror. If the image is magnified, it is a concave mirror. If the image is diminished, it is a convex mirror. 

A spherical mirror is that mirror whose reflecting surface is the part of a hollow sphere of glass. The spherical mirrors are of two types: concave mirrors and convex mirrors. Difference between concave mirror and convex mirror: A concave mirror is that spherical mirror in which the reflection of light takes place at concave surface (or bent-in surface), whereas a convex mirror is that spherical miror in which the reflection of light takes place at the convex surface (or bulging out surface). Concave mirror converges the parallel rays of light that fall on it, whereas convex mirror diverges the parallel rays of light that fall on it. 

Glass transmits 50% of heat radiation coming from a hot source like sun but does not allow the radiation from moderately hot bodies to pass through it.

We know that h = 2Scosθ/rpg

Surface tension of hot water is less than the surface tension of cold water. Moreover, due to thermal expansion the radius of the capillary tube will increase in hot water. Due to both reasons, the height of capillary rise will be less in hot water as compared to cold water.
