Ratnanka offered each thirsty wood cutter some soaked bengalgram and cold water. The hungry and thirsty woodcutters were pleased with Ratnanka’s service.

Madananka was a young merchant living in Ujjain. As he lost his father, his mother brought him up with great affection and love. Unfortunately, he turned out to be a vagabond. Hoping he would become normal and settle down, his mother got him married to a girl but he became worse. One day he left his house deserting his mother and pregnant wife. His wife gave birth to a son and he was named Ratnanka. He too was brought up with affection and care and given good education. When he was ten, his grandmother told him to take up some business to earn their living. She advised him to go to Yakshadatta and borrow some money from him. Yakshadatta, a well-to-do merchant living in the neighbouring village, lent money to the poor but capable persons. Ratnanka met Yakshadatta and requested him to lend him some money for business. He promised Yakshadatta that he would repay the amount soon. Yakshadatta pointed towards a dead rat and told Ratnanka that it was the capital he could lend him. He also told that an intelligent man could earn millions with that dead rat. Ratnanka took the dead rat and kept it in a cup made out of a leaf. A merchant purchased it for feeding his cat and gave him a handful of bengalgram. Ratnanka took the bengalgram home and soaked it. Then he added some salt and pepper to the bengalgram. He offered some soaked bengalgram and cold water to the hungry and thirsty woodcutters. They were pleased with his service and gave him two pieces of firewood each. Ratnanka sold the firewood away for two rupees in the city. He gave one rupee to his grandmother towards savings and purchased bengalgram with the other rupee. Again he offered soaked bengalgram and cold water to the woodcutters. In this way he collected many cart-loads of fuel within a month. When there was scarcity of firewood in the city, he sold the firewood and earned a hundred gold coins. He became one of the leading merchants in that city within two years. Then he wanted to show his gratitude to Yakshadatta. He got a rat made of gold and carried it in a procession to the residence of Yakshadatta. Ratnanka told Yakshadatta his success story and requested him to accept the golden rat as repayment of the loan and also as a token of his gratitude. Yakshadatta was pleased with the intelligence and gratitude of Ratnanka.

Ratnanka got a rat made of gold and kept it in a silver tray and carried in a procession with pomp. He led the procession to the residence of Yakshadatta. Ratnanka told Yakshadatta that he became a millionaire by his grace. He also told him that his wise saying and the capital which he borrowed from him made him a rich man. He told Yakshadatta that he had come to repay his debt in the shape of a golden rat and requested him to accept it as a symbol of his gratitude. Thus Ratnanka showed his gratitude to Yakshadatta.

Madananka’s mother hoped that he would become normal and settle down if he was married. So, she got him married to a girl.

Ratnanka made a cup out of a leaf and placed the dead rat in that cup. He carried it through streets crying, A rat for sale !” A merchant purchased that dead rat for feeding his cat and gave him a handful of bengalgram.

Yakshadatta was a well-to-do merchant. He lent money to the poor but capable persons. He was an intelligent person.

Ratnanka had collected the firewood from the woodcutters by offering each of them some soaked bengalgram and cold water. Ratnanka sold the firewood away for two rupees in the city. He gave one rupee to his grandmother towards savings and purchased a Kuncham of bengalgram with the other rupee. Out of this he soaked one kilo everyday and sat under the same tree with cold water. He collected many cart-loads of fuel within a month and sold it when there was a scarcity of firewood in the city. Thus the firewood fetched him a hundred gold coins.

Yes, immediately after the opening of flower. e.g., Poppy.

Examples: -

2. Contraction of pupil when there is bright light.

The correct answer is (A) rose end

Blinking of eyes, withdrawing of hand upon pricking, suckling to breast by infant, swallowing, knee jerk, sneezing and coughing are some of the unconditional reflexes.

Unconditioned reflexes are inborn or hereditary and permanent while the conditioned reflexes are temporary, learnt or acquired during lifetime.

Number of stamens in Schizanthus is 2.

Taxonomy is “the science dealing with the study of classification including the bases, principles, rules and procedures”.

The use of a thermostable DNA polymerase Thermus aquaticus which remain active during the high temperature induced denaturation of double stranded DNA.

(d) Fusion of gametes

(c) Bryophyllum

Staminate, Pistillate

Extra axillary scorpiod cyme is called Rhiphidium.

The PCR technique is carried out in following to main steps.

(1) Denaturation & Separation of two strands of ds. DNA : The double strand DNA is subjected to denaturation at high temperature (950C) for separation of single stranded strands. These strands now serve as the template strands for synthesis of DNA. 

(2) Annealing : The two sets of primers are added which undergo annealing at 3' end of each separated strand. 

(3) Extension : The Thermostable DNA (taq polymerase) helps in adding the nucliotides complementary to the template thereby extending the primer. These steps are repeated many times for obtaining several copies of desired DNA.

सबसे छोटी संख्या = 234569

सबसे बड़ी संख्या = 965432

965432 में लाख के स्थान पर अंक = 9

234569 में लाख के स्थान पर अंक = 2 9 > 2

अतः 965432 > 234569 तथा 234569 < 965432

965432, 956432, 956342, 659432, 652349, 543296, 549632, 432965, 324569, 234569 आदि। इसी प्रकार अनेक संख्याएँ बना सकते हैं।

The pressure of a gas related to the number of molecules of the gas at constant volume and temperature is P ∝ N.

A group or a series of organic compounds each containing a characteristic functional group forms a homologous series and the members of the series are called homologous.

The pressure of a given sample of a gas related to temperature at constant volume is P ∝ T

It may be defined as an atom or group of atoms joined in a specific manner which is responsible for the characteristic chemical properties of the organic compounds.

eg: hydroxyl group (- OH)

aldehyde group (- CHO)

carboxylic acid group (-COOH) etc.

It is due to the presence of different alkyl groups on either side of functional group in the molecule. 

Ex. C₄H₁₀O represents C₂H₅OC₂H₅ and CH₃OC₃H₇. 

Pressure is directly proportional to the temperature , i.e; P ∝ T.

A reagent that brings an electron pair is called nucleophile. 

i.e., nucleus seeking e g OH^-, CN

A species having a carbon atom possessing sextet of electrons and a positive charge is called carbocation.

Mixture:

• Formed by physical combination of two or more pure substances in any ratio. Chemical identity of the pure components remains maintained in mixtures. 
• Homogeneous mixtures are those whose composition for each part remains constant. 
• Example, Aqueous and gaseous solution.
• Heterogeneous mixtures are those whose composition may vary for each and every part.
• Example, Soil and concrete mixtures.

The greater the s – character of the hybrid orbital’s, the greater is the electro negativity. Thus, a carbon atom having an sp hybrid orbital with 50% s – character is more electro negative than that possessing sp² or sp³ hybridized orbital’s.

Compound: 

• It is a non-elemental pure compound, Formed by chemical combination of two or more atoms of different elements in a fixed ratio. .Examples: H₂O, CO₂, C₆H₁₂O₆ etc.

A unit obtained by multiplying or dividing one fundamental unit by another fundamental unit(S) is known as derived unit. 

EXAMPLE : Density of a substance is defined by : 

Density = mass of sample / volume of sample 

= SI unit of mass / SI unit of volume 

= kg/m³ 

= kg m^-3

A unit obtained by multiplying or dividing one fundamental unit by another fundamental unit(S) is known as derived unit.

EXAMPLE : Density of a substance is defined by :

Density = mass of sample / volume of sample

= SI unit of mass / SI unit of volume

= kg/m³ = kg m^-3.

i. The SI unit of density is derived as follows :

Density = \(\frac{SI\,unit\,mass}{SI\,unit\,volume}\) 

= \(\frac{kg}{m^3}\) 

= kg m^-3

ii. CGS unit of density : g cm^-3

[Note : The CGS unit, g cm^-3 is equivalent to \(\frac{g}{mL}\) or g mL^-1.]
