(a) afforestation

(a) Carbon is present in both living and non-living things.

(b) of paved surfaces and concrete constructions

(a) increased melting of ice such as glaciers and ice sheets

(d) warmer waters and changes in the acidity level of the oceans.

Mass m = 40 kg.
height h = 5 m.
Potential energy PE = mgh = 40 × 9.8 × 5 = 1960J.
KE at half way down = PE at halfway down = \(mg\frac{h}{2}\)
= 40 × 9.8 × \(\frac{5}{2}\) = 980 J.

➢ Diffusion in solids is a very, very slow process.

Example :

➢ If we write something on a blackboard and leave it uncleaned for a considerable period of time (say, at least 10 to 15 days), we will find that it becomes quite difficult to clean the blackboard afterwards. This is due to the fact that some of the particles of chalk have diffused into the surface of backboard.

➢ If two metal blocks are bound together tightly and kept undisturbed for a few years, then the particles of one metal are found to have diffused into the other metal. 

Gases diffuse very rapidly. The rate of diffusion of a gas varies inversely as the square root of its density.

i. survived

ii. rot

iii. fix

iv. recover

• Her team mates may make fun of her and won’t look up to her as a leader. She may end up taking the cleaning activity all by herself and the team will not listen to her at all. 
• However, if she views it as a challenge and responds positively to the situation, she might be able to overcome her weaknesses.

• I will intervene and use my friendship to stop the bullying immediately. Then I will talk to my friend to figure out why she was resorting to bullying. 
• I will also try to make her understand why engaging in such behaviour is wrong.

• I will certainly be very disappointed and upset at first. But then I will try to analyse the causes of getting such less marks. 
• I will study more, waste less time in leisure activities, pay more attention in class and clarify my doubts immediately. It will help me to get good marks in the next term.

Correct option is (B) 4

Enzyme that cleaves protein is Protease

Enzyme that cleaves DNA is DNase

Repressors are proteins which are able to bind the operator region of operon and prevent the RNA polymerase from transcribing the operon.

Anticodon is a triplet of nucleotides present on the anticodon loop of t-RNA, which is complementary to codon on m-RNA.

Introns are the non-coding sequences in DNA or hnRNA.

1. An operon is a unit of gene expression and regulation. 

2. It includes the structural genes and their control elements. Control elements are promoters and operators. 

3. The structural genes code for proteins, r-RNA and t-RNA that are necessary for all the cells. 

4. Promoters are signal sequences in DNA. They start the RNA synthesis. They also act as sites where the RNA polymerases are bound during transcription. 

5. Operators are present between the promoters and structural genes.

6. There is repressor protein that binds to the operator region of the operon. 

7. There are regulatory genes which are responsible for the formation of repressors which interact with operators.

A, B and C are A : m-RNA, B : r-RNA, C : t-RNA

Privatisation means allowing the private sector to set up industries that were previously reserved for the public sector. Privatisation is the process of transferring ownership of Pubilc Sector Units (PSUs) to the private sector. 

Measures were taken for Privatisation: 

• Dereservation Policy: The number of industries reserved for the public sector has been gradually reduced to only two and all other industries are deserved i.e. opened up for the private sector. 
• Establishment of BIFR: Board of Industrial and Financial Reconstruction (BIFR) has been set up to make the decisions about sick public sector units i.e. whether to close or revive them. 
• Creation of NRB: National Revival Board (NRB) has been set up to take care of unemployed workers of the sick units. 
• Status of Navratna: On the basis of strategic importance, nine public sector enterprises were selected and given the status of ‘Navratnas’ i.e. they were given the full managerial and financial freedom to make them global giants. Some are ONGC, BHEL, HPCL, SAIL, etc.
• Disinvestment: This was an important step undertaken to reform public sector. The Government started selling PSUs to the private sector, those are running at a loss. e.g. Maruti Udyog Ltd. VSNL, etc.

1 – c

3 – b

Answer is: Federalism

1. In the second five-year plan, emphasis was given to develop the public sector.

2. PSUs were working inefficiently, lack of competitive nature, dependence on bailed out by the government, lack in cost-effective working nature, etc. led to poor performance of PSUs.

3. Privatisation and Disinvestment.

4. Under privatisation, ownership is transferred from the public sector to the private sector because the private sector is more efficient in resource allocation, management and provides better services to the customers. Privatization can be an important source of revenue to the government and help to develop local capital markets.

5. In 2008, privatisation of VSNL took place. VSNL was completely acquired by the TATA group and renamed TATA Communication. At present TATA Communication is providing internet services globally. Its cable network is in 200 countries and territories. The annual income is 5575.96 crores and the net profit is 266.63 crores in 2018.

Liberalisation means ‘economic freedom’ or ‘freedom for economic decisions’. All economic units are free to take decisions for self-interest e.g. consumer, producer, owner of a factor of production, etc.

Measures were taken for Liberalisation: 

• The flexibility of Interest rate: Banks are free to determine the rate of interest. Earlier it was determined by RBI. 
• Freedom for expansion of industries: The industries are free to expand and produce. The producers are now free to produce anything on the basis of demand in the market. 
• Abolition of Monopolies and Restrictive Trade Practices: Companies falling under MRTP Act are given concession. Firms are free to make decisions regarding investment. 
• Reforms in FERA: FEMA (Foreign Exchange Management Act) was introduced in place of FERA. It will encourage international trade. 
• Investments in infrastructure: Domestic and foreign investment is allowed in infrastructure to improve its quality. 
• Encouragement to foreign technology: The use of foreign technologies allowed in high-priority industries resulting in cost cuts. 
• SEBI: SEBI was formed to secure the interest of the investors and to regulate the securities market.
