Irrigation in India includes a network of major and minor canals from Indian rivers, groundwater well based systems, tanks, and other rainwater harvesting projects for agricultural activities. Of these groundwater system is the largest.

Collect some water in a bottle and take it into the nearby lab.
Using brush or filler gently take some amount of water and add a drop of water in the microscopic slide.
Using a good quality microscope examine the slide.
Keep the microscopic slide under the microscope and using virtue and a clear focal lens observe the microorganisms present in the water.
Try to identify the microorganisms present in the water.

Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges. Lightning is caused by electricity moving in between clouds or between the clouds and the ground. The electricity is formed when ice and water particles move around rapidly inside the clouds. As the particles move they become oppositely charged and they separate.

• During a thunderstorm, the air currents move upward and water droplets move downward. These movements take at very fast pace and it results in separation of charges in the clouds.
• The positive charges accumulate at the upper edges of the clouds and the negative charges accumulate at the lower edges of the clouds. Scientists are yet to understand the exact reason for this.
• At the same time, the ground becomes positively charged.
• Air is a bad conductor of electricity under normal circumstances. But when the amount of charge becomes too much in the clouds, the air is not in a position to hold on to this charge. As a result, the electric charge is transferred to the ground. This appears like a bright streak of light across the sky; which lasts for a few seconds.

Thank you so much Hansika. For ur timely help. ????

I defining this question by giving the example that you have seen when you people makes concentration of water more than concentration of milk hear milk got dilution same as concentration of water is more in acid than concentration of acid it is called dillusion

Microorganisms are harmful as they cause many diseases. There are many microbes which cause several diseases in plants, animals & human beings. Such disease-causing organisms are called Pathogens. We can also say that pathogens are diseases causing microorganisms. Pathogens include bacteria, viruses, fungi & protozoa.

Protozoa: These are unicellular microscopic organisms similar to animals that can move about to capture food and are heterotrophic in nature. They are mostly aquatic in nature. Amoeba, paramecium are some examples of protozoa.

Microorganism are very tiny organism which can be not seen by naked eye only seen by under microscope the microorganisms friend and foe, friend means the organisms are helpful for us while foe means enemy these microorganism are not helpful for us.

Foe means an enemy

Microbes or microorganisms are tiny organisms which are so small that we cannot see them with an unaided eye. Some microorganisms can be seen with the help of a magnifying glass (such as fungus that grows on bread) while some can only be seen when you use a microscope (such as bacteria and protozoa).

The process of separating crude petroleum oil into more useful fractions is called refining. The refining of petroleum into different fractions is based on the fact that the different fractions of petroleum have different boiling point. The refining of petroleum is carried out in an oil refinery.

Irrigation

Watering crop is known as Irrigation. Many new and old methods are used for doing this.

The process of watering the crops is called irrigation Two methods of irrigation are: (i) sprinkle (ii)Drip syatem

The process of watering the crops is called irrigation.
 Two methods of irrigation are:
 (i)   Sprinklers: Sprinklers work as fountains. Long perpendicular pipes have holes at regular distances. When water is supplied, it comes out of these holes and spray water in field. These holes have rotating nozzles which sprinkle water in all directions. They control wastage of water.

(ii)   Drip System: This system is used to save water as it allows the water to flow drop by drop at the roots of the plants. It is the best technique for watering fruit plants, gardens and trees. Water is not wasted at all.

A place where grains are stored in gunny bags on a large scale are called granaries.

•Fertilizers are chemical in nature and these are  manufactured in factories.
Manure is an inorganic substance that is obtained from decomposition of vegetable and animal wastes.

•Microbes are not needed for fertilizers formation.
Microbes are needed to form manure  since they degrade the organic substances.

•Fertilizers are easy to transport ,store and apply to crops.
It is difficult to transport ,store and apply manure to crops

.•Fertilizers do not restore soil texture.
Manure restore soil texture.

•Fertilizers do not help in retention of water.
Manure help in the retention of water.

 

1. Store the grains in dry place.

2. Clean the grains before storage.

3. Good warehouse management practices.

4. Heat treatment for disinfection before storage.

Rhizome is a vegetative plant structure which arises from the modified stem that grows horizontally along the underground or ground surface with buds.

Infection with a pathogen does not necessarily lead to disease. Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease occurs when the cells in your body are damaged as a result of infection and signs and symptoms of an illness appear. Pathogens cause illness to their hosts through a variety of ways. The most obvious means is through direct damage of tissues or cells during replication, generally through the production of toxins, which allows the pathogen to reach new tissues or exit the cells inside which it replicated.

Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease occurs when the cells in your body are damaged as a result of infection and signs and symptoms of an illness appear. ... Pathogenic microbes challenge the immune system in many ways.

Price

• Acrylic fibre comes in a range of prices, but generally it’s cheaper than similar wool yarn.

Color options

• Acrylic fibre is easy to dye in all kinds of vibrant colors. It is often easier to find the desired shade in acrylic fibre vs wool.
• Wool naturally comes in a range of beautiful natural colors so you can get a range of browns and greys without even dying the fibre. However, wool that is not white becomes trickier to dye.
• Acrylic fibre retains color well. There will be less of an issue with colors fading or

Care of garments

• It is easier to wash garments made from acrylic fibres than wool fibres since acrylic fibres don’t felt together.
• Unless the wool fibre is superwash-treated you can’t just throw it in the washing machine - and forget about the dryer!

Fibre properties

Both fibres can be made into warm garments, but wool will keep warm even when wet. Wool garments ”breathe” better. Acrylic can be made to mimic other fibres than wool, it’s very versatile.

A place where agriculture is done

Agricultural land is defined as the land area that is either arable, under permanent crops, or under permanent pastures. Land under permanent crops is cultivated with crops that occupy the land for long periods and need not be replanted after each harvest, such as orchards and vineyards. Agricultural land has not been defined in the Income Tax Act but in common parlance, agricultural land is a land on which agricultural activities are carried out. Agricultural activity has been held to be an activity where human effort has resulted in growing crops.

we must prepare the land by sprinkling water on land

we must prepare the land by sprinkling water and then do a good seed selection for healthy seeds

We must prepare the land by sprinkling water on it

We must fill the field with water before sowing the seeds

Preparation of the soil is the 1st step must to done bfore sowing.

Following are the important functions of the hypothalamus :

• Its main function is maintaining the body’s internal balance- homeostasis.
• It also connects the endocrine and the nervous system.
• Hypothalamus stimulates or inhibits many of the body’s activities in order to maintain homeostasis, such as regulating body temperature, appetite and body weight, heart rate and blood pressure, etc.
• It is involved in many essential functions of the body, including:

1. Childbirth.
2. Emotions.
3. Sleep cycles.
4. Balancing body fluids.
5. Appetite and thirst control.
6. Blood pressure and heart rate.

Selecting seeds which is high in quality is also an important factor that determines the growth of a good plant as seeds that are too tiny, broken and affected by harmful microorganisms can make the plant get infected that grows from it. So, only very best seeds must be sown.

In the chapter 4, Materials-->a substance that can be used for making or doing something Metals are a good conductor of electricity which means that they can conduct electricity due to the free moving electrons present in them. Copper is used as wiring as it is a good conductor of electricity. Metals have high melting points and high boiling points as they have strong metallic bonds. All metals are physically lustrous. They have a lustre that makes them shine. Gold is used for making jewellery. Metals are hard, they can’t be broken easily and require a lot of energy and strength to break. Iron is used to make cars, buildings, ships, etc. Metals weigh a lot as they have a high density. Metals are heavy for their size. They don’t have flexibility and have tensile strength. Metals can’t be stretched. Metals are great conductors of heat. That’s why pots, pans, vessels are made of metals.

Lactometer is an instrument used to check for the purity of milk by measuring the density. of milk. An instrument used to find out the content of water in milk Or test the richness of milk. Thus termed as LACTOMETER. The Lactometer works on principle of gravity of milk.

So that it will form a large amount of curd as the bacteria named lactobacillus helps in formation of it. It is left undisturbed so that the bacteria can multiply itself and produce curd.

Bacreria of curd mix with milk and form into curd

Some differences between fertilizer and manure are: 1. Fertilizer is an inorganic chemical synthesized artificially while manure is a combination of inorganic and organic substances obtained naturally by decomposing cattle excreta, plant litter, and human wastes. 2. Fertilizer can add only a specific nutrient to the soil whereas manure can provide many useful nutrients. 3. A fertilizer cannot add humus to the soil whereas manure can.
