5.

How many employment opportunities are created each year under Nehru Employment Scheme?

Answer»

10 lakh employment opportunities are created each year under Nehru Employment Scheme.

6.

Give reason: Ammonia has higher melting and boiling points.

Answer»
  • In solid and liquid state, NH3 molecules get associated together through hydrogen bonding. 
  • As a result, extra amount of energy is required to break such intermolecular hydrogen bonds. Hence, ammonia has higher melting and boiling points.
7.

Noble gases have very low melting and boiling points. Why?

Answer»

Noble gases are monoatomic, the only type of interatomic interactions which exist between them are weak van der Waals forces. 

Therefore, they can be liquefied at very low temperatures and have very low melting or boiling points.

nobel gases have low interatomic force because of that they low tendency to react and thats all

8.

Noble gases do not form compounds with hydrogen. Why?

Answer»

Noble gases have a stable electronic configuration, and so are unreactive. Since, they are chemically inert, they do not form compounds with hydrogen.

9.

Explain the variation in (1) ionisation enthalpy and (2) electron gain enthalpy in group 18 elements.

Answer»

(1) Ionisation enthalpy : 

  • In general, group 18 elements have high values of ionisation enthalpy. 
  • In a period, each noble gas has the highest ionisation enthalpy. 
  • The noble gases have electronic configuration, ns2 np6, they have complete octet with paired electrons and very stable closed-shell electronic configuration. Therefore high energy is required to remove the electron from valence shell. 
  • Down the group ionisation enthalpy decreases.

 (2) Electron gain enthalpy :

  • Group 18 elements have electronic configuration ns2 np6 and complete octet of electrons, hence they have no tendency to accept electrons. 
  • Therefore, they have a large positive electron gain enthalpy. 
13.

Which element from the following pairs has higher ionization enthalpy?B and TI, N and Bi

Answer»

Among B and Tl, boron has higher ionization enthalpy while, among N and Bi, nitrogen has higher ionization enthalpy.

14.

15.

A light ray falls on one of the faces of a prism at an angle 40° so that it suffers angle of minimum deviation of 30°. Find the angle of prism and angle of refraction at the given surface

Answer»

Given that, incident ray on one of the prisms (i1 ) = 40° 

Angle of minimum deviation (D) = 30° 

Angle of prism (A) = ? 

A+D = 2i1 

⇒ A = 2i1 – D 

⇒ A = 2(40°) -30° 

= 80° – 30° 

= 50° 

∴ Angle of prims (A) = 50° 

Angle of refraction (r1 ) = ?

We know r1 = A/2 [∴ r1 +r2 = A]

⇒r1 = 50°/2 = 25°  

∴ Angle of refraction (r1) = 25°  

16.

What is a prism?

Answer»

A prism is a transparent medium separated from the surrounding medium by consisting two refracting plane surfaces which are inclined.

17.

When objects at different distances are seen by the eye which of the following remains constant? A) focal length of eye-lens B) object distance from eye-lens C) the radii of curvature of eye-lens D) image distance from eye-lens

Answer»

Correct option is: D) image distance from eye-lens

18.

Why do we use lenses in spectacles to correct defects of vision?

Answer»

The process of adjusting focal length is called “accommodation”. This process has to be done by eye itself. Sometimes the eye may gradually lose its power of accommodation. In such condition, the person cannot see the object clearly and comfortably. In this situation, we have to use lenses in spectacles to correct defects of vision.

19.

How can we get same image distance for various positions of objects?

Answer»

For different positions of object, the image distance remains constant only when focal length of lens changes.

20.

How does eye lens change its focal length? (OR) What is the role of ciliary muscles in the eye ? Write the answer in one or two sentences only.

Answer»

The ciliary muscles to which eye lens is attached help the eye lens to change its focal length by changing the radii of curvature of eye lens

28.

Explain why the term ‘homozygous’ and ‘heterozygous’ with respect to an X-linked trait are applicable to human females but not to human males?

Answer»

Females have two X chromosomes. Therefore, two alleles of a gene are present on the homologous chromosomes which can be either in a heterozygous or homozygous condition. Whereas males have only one X chromosome and one Y chromosome. Since, these do not have homologous chromosomes, so a single form of gene is present.

29.

Define homozygous.

Answer»

When similar pair of alleles are present for a character, it is called homozygous, e.g., TT.

30.

Define heterozygous.

Answer»

When dissimilar or different pairs of alleles are present for a character, it is called heterozygous condition, e.g., Tt.

31.

Why is there a need to conserve biodiversity?

Answer»

Reasons for Biodiversity Conservation

▪ There are three main reasons for conserving the biodiversity which have been classified into the following categories:

i. Narrowly utilitarian arguments 

• Human beings derive direct economic benefits from nature, like food, firewood, fibre, construction material, industrial products (resins, gums, dyes, tannins, etc.) and medicinally important products. 

ii. Broadly utilitarian arguments 

• Biodiversity plays a major role in maintaining and sustaining supply of goods and services from various species as well as ecological systems. 

iii. Ethical reasons 

• There are thousands of plants, animals and microbes on this earth which are not useless. Every one has some intrinsic value even if it is not of any economic value to us.

32.

Define recessive factor

Answer»

The factor or allele of a character which fails to express its effect in the presence of its alternative allele and only expresses itself in the homozygous state is called the recessive factor.

33.

Define dominant factor.

Answer»

The factor or allele of a character which expresses its effect in the presence of its alternative allele is called the dominant factor.

34.

Name the inheritance where both the genotypic and phenotypic ratios are same.

Answer»

In incomplete dominance, the inheritance pattern has the same genotypic and phenotypic ratio of 1 : 2 : 1.

क्या भौगोलिक पृथक्करण अलैंगिक जनन वाले जीवों के जाति उद्र्भव का प्रमुख कारक हो सकता है? क्यों अथवा क्यों नहीं?

Answer»

अलैंगिक जनन में उत्पन्न जिव लगभग एक दुसरे के सामान होते है तथा उनमें बहुत थोड़ा अन्तर होता है | इस क्रिया में विभिन्नताएँ DNA प्रतिकृति के दौरान ही होती है तथा ये विभिन्नताएँ बहुत कम होती है | भौगोलिक पृथक्करण इनमें जाति उद्र्भव का प्रमुख कारक हो सकता है क्योंकि इसके कारण ही नए वातावरण में जीवित रहने वी जीव अपने अन्दर नए उत्पन्न करते है |

41.

Answer»

मृत जीवों के अवशेष ,चट्टानों पर के चिन्ह या उम्नके साँचे व शरीर की छाप जो हजारों साल पूर्व जीवित थे | इस तरह के सुरक्षित अवशेष जीवाश्म कहलाते है | ये जीवाश्म हमें जैव – विकास प्रकम के बारे में कई बातें बताते है जैसे कौन से जीवाश्म नवीन है तथा कौन से पुराने , कौन सी स्पीशीज विलुप्त हो गई है | ये जीवाश्म विकास विभिन्न रूपों तथा वर्गों कभी वर्णन करते गुणों को भी ज्ञात कर सकते है |

42.

क्या एक तितली और चमगादड़ के पंखों को समजात अंग कहा जा सकता है? क्यों अथवा क्यों नहीं?

43.

समजात तथा समरूप अंगों को उदाहरण देकर समझाइए।

Answer»

वे अंग जो आधारभूत संरचना में एक समान है परन्तु भिन्न – भिन्न कार्य करते है , समजात अंग कहलाते है उदाहरण – पक्षी , जल – स्थलचर अन्य के चार पैर होते है परन्तु सबके कार्य भिन्न है | इसके ठीक विपरीत वे अंग जिनकी आधारभूत संरचना एक समान नंही होती परन्तु भिन्न – भिन्न जीवों में एक ही सामान कार्य करते है ,समरूप अंग कहलाते है | उदाहरण – चमगादड़ व पक्षी के पंख | चमगादड़ के पंख दिर्घित अंगुली के बीच की त्वचा के फैलने से परन्तु पक्षी पूरी अग्रबाहू की त्वचा के फैलने से बनती है |

विभिन्नताओं उत्पन्न होने से किसी स्पीशीज का अस्तित्व किस प्रकार बढ जाता है ?

Answer»

पीढ़ी दर पीढ़ी जीवों के अनुसार स्वयं को बदलना पड़ता है | वह वातावरण के अनुसार अनुकूलित होने पर ही जीवित रह सकते है | अतः विभिन्नताओं के उत्पन्न होने से किसी स्पीशीज का अस्तित्व बदल जाता है | तथा यह लैंगिक जनन में उत्पन्न होती है |
