Providing security from risk of life to an individual is called personal insurance.

For regulation of insurance agencies in India, Indian Regulation Development Authority (IRDA) was established.

The correct option is A) Scion

The answer is A) Scion 

A person within the age group of 18-70 years can have this insurance. Premium of ₹ 12 annually is credited from the insured’s account directly. This is an annual insurance. This insurance was started by prime minister Narendra Modi in 2015. In case of accidental death or full disability, ₹ 2 lakhs will be given to nominee, and in case of partial permanent disability, ₹ 1 lakh is given to nominee.

Dear Diary,

 22 May, 2015

I had a very eventful day today. I made three new friends. The cyclone which whisked me to the wonderful Land of Oz is where I met them. They had come to this land because they wanted help from the Wizard of Oz. We had to journey through a forest before we reached this wonderful land. We came across a lot of difficulties. Each time my friends helped me out of it. We have finally reached the wonderful Emerald City of Oz. I will let you know what happens as we have to go in search of the Wizard of Oz.

Dorothy L, sayers is the author of how Free is the press.

Shiga Naoya is a Japanese short story wirter.

'Civilization, in real sense of the term, consists not in the multiplication, but in the deliberate and voluntary restriction of wants'is from Indian Civilization and Culture.

The following extract has been taken from the chapter, 'The Earth' penned by H.E.Bates, In his this story through the extract sayers ways that Benjy wanted some one to help him to take care of his hens business, be it a woman would be more comfortable and as he got Florence as his companion, he decided to marry her. So that both would permancntly handle the hans business.

The given extract is from the chapter 'How Free is the Press', written by Dorothy L, Sayers. The author wants to say that our press don't enjoy full freedom. Governments put a bar on their freedom and and they are provided only limit'ed freedom of expression.

The Middle English had five dialects. They were known as 

(i) Northern, (ii) Southern, (iii) East Midland, (iv) West Midland, and (v) Kentish.

The Northumbrian of Old English is now called northen, West-Saxon is now southern and Mercian is divided into two dialects which came to be known as East Midland and west Midland dialect. Kentish remained unchanged.

In Mexico and Switzerland, English language is used extensively.

Can you speak English.

"The Earth' is a very fine & interesting story written by the famous writer, H.E. Bates. The author has beautiful presented the reality of what happens in most of the families in present day life. The story highlights the tragedy of those parents who put too much trust on their children who, however, betray them in the end, This story is the life sketch of farmer Johnson and his son, Benjy.

Johnson is a farmer,who has no land of his own. He has obtained about four acre of plot on lease for cultivation helping him in meeting family's expenditure. Benjy is mentally underdeveloped. His father goes to a doctor for consultation who advises Johnson to get his son engaged in some business, preferrably in poultry business. Accordingly Benjy is engaged in that business. The income out of the self of hen's egg is deposited in the bank in Benjy's name. When Benjy becomes twenty one year old his father father hands over the amour deposited with the bank to Benjy,By the time Benjy's passbook showed a balance of Rs two hundred thirty pound. Benjy purchases some land of Mr. withmore from that money and expands his poultry business on the land purchased. He becomes a rich man his poultry farm against his parent's will. Then there comes a change in his attitude towards his parents. At first he directs his parents to shift to a smaller room of the house after sometime he stops joint kitchen arrangement and leaves his parents isolated. Afterwards finally he flatly directs his parents to shift from his house and to settle themselves some where else. Not only this, he personally drives them away from their home by his car.

Thus the story is a true description of wrong dealings and behaviours of a son with his parents, that happens at present. 

English is an International language not because it is read and spoken by the largest number of people but also because it is read and spoken by the largest number of countries. Almost all the former colonies of Britain have English as an important language.India being a colony of British empire has English as an important language.

Applications of biotechnology : 

(a) Nutrient Supplementation: One of the biggest uses of biotechnology is the infusion of nutrients into food in situations such as aid. Therefore, it provides food with heavy nutrients that are necessary in such situations. An example of this application is the production Golden Rice where the rice is infused with beta-carotene. The rice has Vitamin A, which the body can easily synthesise. 

(b) Abiotic Stress Resistance: There is actually very little land on earth that is arable with some estimates place it at around 20 percent. With an increase in the world’s population, there is a need for the food sources available to be as effective as possible to produce as much food in as little space as possible. There is also need to have the crops grown to be able to make use of the less arable regions of the world. This means that there is a need to develop crops that can handle these abiotic stresses such as salinity, drought and frost from cold. In Africa and the Middle East, for instance, where the climate can be unforgiving, the practice has played a significant role in the development of crops that can withstand the prevailing harsh climates. 

(c) Industrial Biotechnology: The industrial applications of biotechnology range from the production of cellular structures to the production of biological elements for numerous uses. Examples include the creation of new materials in the construction industry, and the manufacture of beer and wine, washing detergents, and personal care products. 

(d) Strength Fibres: One of the materials with the strongest tensile strength is spider webs. Amongst other materials with the same cross sectional width, spider webs can take more tensional force before breaking than even steel. This silk has created a lot of interest with the possible production of materials made from silk including body armour such as bullet proof jackets. Silk is used because it is stronger than Kevlar (the material most commonly used to make body armour). 

Biotechnological techniques have been used to pick the genes found in spiders and their infusion in goats to produce the silk proteins in their milk. With this initiative, it make production easier as goats are much easier to handle compared to spiders and the production of silk via milk also help make the processing and handling much easier compared to handling the actual silk strands. 

(e) Biofuels: One of the biggest applications of biotechnology is in the energy production sector. With fears over the dwindling oil resources in the world and their related environmental impacts, there is a need to protect the globe’s future by finding alternative environmentally friendly fuel sources. Biotechnology is allowing this to happen with advances such as using corn to produce combustible fuel for running car engines. These fuels are good for the environment as they do not produce the greenhouse gases. 

(f) Healthcare: Biotechnology is applied in the healthcare sector is the development of pharmaceuticals that have proven problematic to produce though other conventional means because of purity concerns.

Officially English has a status of assistant language, but in fact it is the most important language of India, The reason Indians give such importance of English is related to the fact that India was a British colony. The British rulers began building their universities in India from 1857. Then onwards, English became the first language in Indian education.Even today in India. English rules its emphasis in schools and university levels.

Production of monoclonal antibodies : It involves following steps -

(a) First a mouse or other animal is injected with specific antigen. 

(b) The animal will develop an immune response and produces antibodies against the antigen in B-lymphocyte cells in spleen. 

(c) The spleen of the animal is taken out and its B- lymphocyte cells are isolated. 

(d) In the same way, the cells producing bone marrow cancer (myeloma cells) are isolated. These cells should not be able to synthesis their own nutrients. 

(e) Both the myeloma cells and antibody-producing cells are made to fuse together in cultures. The fused cells are named hybridomas.

(f) The unfused myeloma cells are separated from fused myeloma cells by growing them on nutrient deficient medium (needed by myeloma cells). 

(g) The surviving fused myeloma (hybridoma) cells are grown separately and each clone is tested for production of antibody. 

(h) The clones which show positive results are isolated and cultured for large scale production of antibody. 

Two basic processes involved in sexual reproduction are : 

(i) Gametogenesis : It involves the formation of haploid gametes (sperms and ova) in the primary sex-organs called gonads. 

(ii) Syngamy : Syngamy (fertilization) involves the complete and permanent fusion of two haploid gametes to form a diploid zygote.

Puberty is the period during which growing boys or girls undergo the process of sexual maturation. Puberty involves a series of physical stages or steps that lead to the achievement of fertility and the development of the so-called secondary sex characteristics, the physical features associated with adult males and females (such as the growth of pubic hair). While puberty involves a series of biological or physical transformations, the process can also have an effect on the psychosocial and emotional development of the adolescent.

In lac operon,lactose is the inducer.Inducer binds with repressor protein but repressor cannot bind to op-erator gene,the free operator gene induces the RNA polymerase to bind with promoter and initiates transcription Three structural genes synthesise three mRNAs to produce enzymes.

The mode of reproduction in which formation and fusion of gametes does not take place is called asexual reproduction. Only somatic part is involved in such reproduction.

Clone is a group of individuals of the same species that are morphologically and genetically similar.

Morphologically and genetically similar individuals produced by a single parent. In this young ones are exact copy of their parent.

Reproduction enables the continuity of the race, generation after generation.

The unisexual male flower is called staminate, which bears only stamen. 

• The unisexual female flower is called pistillate, which bears only pistil.
• Heterothallic or dioecious are the terms used to describe this condition.

Unisexual male flower is staminate. Unisexual female flower is pistillate.

Life spans of organisms are not necessarily correlated with their sizes. The sizes of crows and parrots are not very different yet their life spans show a wide difference. Live span of crow is 15 year and of parrot is 140 years. A mango tree has a much shorter life span as compared to a peepal tree.

Some mammals exhibit reproductive cycle only during favourable season. They are called seasonal breeders, e.g., frog, many birds and deer.

Period from birth till natural death. Every organism live only for a certain period of time.

Life Span 

• Period from birth till natural death.Every organism lives only for certain period of time Eg Elephant 60 -90 years, Fruit fly 4-5 weeks.
• Life span of mayfly is one day.Life span of Man is 100 years.Life span of parrot is 140 years
• Life span of a banyan tree is 200 yearsLife span of Tortoises is 100- 150 years 

PHASES OF LIFE SPAN.

• Juvenile phase: The phase of growth before reproductive maturity. 
• Reproductive phase: Reproductive maturity.
• Senescent phase: Phase between reproductive maturity and death.

It is a biological process in which an organism gives rise to young ones similar to itself.

Pollen grains and egg cell respectively.

The alien species compete with our indigenous species. They get invasive and pose a threat to our native species which may even lead to their extinction. 

Carrot grass (Parthenium), Lantana and water hyacinth (Eichhornia) are invasive weed species. Introduction of Clarias gariepinus (an African catfish) for agriculture is an alien invasive species causing thereat to our native catfishes in our rivers.

The period from birth to the natural death of an organism is the life span of that organism.

The mammals which in natural conditions exhibit reproductive cycles only during favourable seasons are called seasonal breeders e.g., sheep.
