Anatomy of Earthworm

Externally, a thin non-cellular cuticle covers the body wall of the earthworm. Underneath this cuticle, a layer of the epidermis, followed by two muscle layers and coelomic epithelium (inner layer) is sheathed. The epithelium consists of a single layer of glandular columnar epithelium.

Census of India:  Ir is responsible for the collection of data related to different demographic characteristics. Data is collected for characteristics such as birth rate, fertility rate, mortality rate, size and composition of the population etc. The information related to all aspects of the population are collected by the investigators appointed by the government. They collect information from each and every household of the country. In India, this exercise is carried after every 10 years. The data collected by the Census of India acts as a mirror for assessing the impact of various programmes and development policies initiated by the government. It also helps in identifying the improvement areas and making the future policy. The first census was conducted in the year 1872 in India and next in 1881.

A protocol is the special set of rules that end points in a telecommunication connection use when they communicate. Protocols also specify the interactions between the communicating entities. Protocols exist at several levels in a telecommunication connection.

Roman Law is the common foundation upon which the European legal order is built. Government: Many modern-day governments are modeled after the Roman Republic. Concepts such as balance of powers, veto, and representation all were developed and recorded by the Romans. The classical jurist Gaius (around 160) invented a system of private law based on the division of all material into personae (persons), res (things) and actiones (legal actions). This system was used for many centuries.

The process of centrifugation is used in dairies to separate cream from milk . 
Centrifugation is a method for separating the suspended particles of a substance from a liquid in which the mixture is rotated at a high speed in a centrifuge machine.
The milk is put in a closed  container in big centrifuge machine .
when the centrifuge machine is switched ON,  the milk is rotated at very high speed in a container. 
Due to this process, milk separates into cream and skimmed milk. 
The cream being lighter floats over the skimmed milk

Milk is a suspension of tiny droplets of oil (cream) in a watery liquid. The process of centrifugation is used to separate cream from milk. The milk is put in a close container in big centrifuge machine. When the centrifuge machine is switched on, the milk is rotated (or spun) at a very high speed in its container. The centrifugal force acts on the milk and due to this, the milk separates into cream and skimmed milk. The cream, being lighter, floats over the skimmed milk and can then be removed.

Articles are words that define a noun as specific or unspecific. Consider the following examples: After the long day, the cup of tea tasted particularly good. ... English has two types of articles: definite and indefinite.

2. Have something unique to say. 
3. Keep it simple. 
4. Speak directly to the reader. 
5. Explain what the article is about. 
6. Explain the importance of the article.

GENERAL GUIDELINES FOR ARTICLE WRITING

1. Always study the given input, information or notes carefully.
2. Arrange them in a systematic order.
3. Develop each point in a simple, grammatically correct language.
4. Your article must present your ideas not in a sketchy but in a coherent and logical manner. Develop your writing into paragraphs.
5. Confine yourself to the given subject. Superfluous and unnecessary details must be avoided at all cost.

Green Revolution in its two phases was successful. In the first phase it increased the yield of wheat dramatically which is a staple food grain in most states.In the second phase the revolution spread to other states and other crops which made India self sufficient in food grains.It helped farmers sell their produce in market which reduced the market price of food grains and food was affordable for all. There were two phases to the Green Revolution; the first spanned from 1960 to the mid 1970's and was “.. primarily concentrated on wheat and was associated with a substantial rise in both yield per unit area and total output, especially in North India.”

There were two phases to the Green Revolution; the first spanned from 1960 to the mid 1970’s and was “..primarily concentrated on wheat and was associated with a substantial rise in both yield per unit area and total output, especially in North India.” (Putnaik,2000:81). As targets were reached the profitability of producing cereals rose also. Putnaik states that “…considerable capitalist investment was visible, especially in North India” which was historically associated with colonial British rule and implemented where irrigation systems were already in place.

The second phase of the Green Revolution dated from 1975 to the present day and has seen the Punjab region becoming ‘phased-in’ as a HYV of rice growing region:

“High yielding rice has emerged as a second crop grown primarily for sale in the traditionally wheat-growing region of North India which had already benefited the most from the first round of technical change” (Patnaik,2000: 82). The capitalistic system saw the same people profiting from phase two as did from phase one and the divide continues to widen.

• Parenchyma, collenchyma and sclerenchyma are three types of simple tissues. Xylem and phloem are types of complex tissues.

• Permanent Tissues:

When the cells take up a specific role and lose the ability to divide they form a permanent tissue. This process of taking up a permanent shape, size, and a function is called differentiation. Thus, cells of meristematic tissue differentiate to form different types of permanent tissue.

Permanent tissues are of two types – simple permanent tissues and complex permanent tissues.

Simple permanent tissues are composed of cells which are structurally and functionally similar. They are of three types – parenchyma, collenchyma and sclerenchyma.

1. Parenchyma –

Parenchyma tissue consists of relatively unspecialised cells with thin cell walls. They are live cells. They are usually loosely packed, so that large spaces between them.  This tissue provides support to plants and also stores food. In some cases, it contains chlorophyll and performs photosynthesis, and then it is called as chlorenchyma. In aquatic plants, large air cavities are present in parenchyma to give buoyancy to the plants to help them float. Such a parenchyma type is called aerenchyma. The parenchyma of stems and roots also stores nutrients and water.

ii. Collenchyma –

The cells of collenchyma tissue are living, elongated and irregularly thickened at the corners. There is very little or no intercellular space. It allows easy bending in various parts of a plant (leaf, stem) without breaking. Thus, provides flexibility to the plant. It also provides mechanical support to plants.  

iii. Sclerenchyma –

The cells of sclerenchyma tissue are dead. They are long and narrow as the walls are thickened due to deposition of lignin. The walls of cells are so thick that there is no internal space inside the cell. This tissue is present in stems, around vascular bundles, in the veins of leaves and in the hard covering of seeds and nuts. It provides strength to the plant parts and makes the plant hard and stiff.

There are 8 major river systems in India, with more than 400 rivers in total. Rivers play an important role in the lives of the Indian people due to their crucial importance in sustenance and their place in Indian religions. Umngot river at dawki village of Meghalaya is considered to be the India's cleanest river. River Umngot in Jaintia Hills district is located 96 km from Shillong and the annual boat race is a major attraction. Arvari river is a small river in the Indian state of Rajasthan, notable for having its flow restored after remaining dry for 60 years. The 45 km long river, flows through the Alwar District of Rajasthan.

A network hub is a node that broadcasts data to every computer or Ethernet-based device connected to it. A hub is less sophisticated than a switch, the latter of which can isolate data transmissions to specific devices.

Network hubs are best suited for small, simple local area network (LAN) environments. Hubs cannot provide routing capabilities or other advanced network services. Because they operate by forwarding packets across all ports indiscriminately, network hubs are sometimes referred to as "dumb switches."
