Question Discussion & Solution

The correct answer is 36.

• In the year 2019-20, 36 Gram Panchayats in Rajasthan are proposed to introduce the 'Zero Budget Natural Agriculture Scheme'.

Key Points

• Rajasthan 'Zero Budget Natural Agriculture Scheme'
  • ​Rajasthan is focusing on ZBNF since State Budget 2019-20.
  • Consequently, it has been decided that Zero Budget Natural Farming will be taken up in 36 Gram Panchayat of Banswara, Tonk and Sirohi at the cost of 10 crores, benefiting 20 thousand farmers.

​Additional Information

• Zero Budget Natural Farming in India 
  • ​It was originally promoted by agriculturist Subhash Palekar, who developed it in the mid-1990s.
  • It is an alternative to the Green Revolution's methods that are driven by chemical fertilizers and pesticides and intensive irrigation. It is a unique model that relies on agroecology.
  • It aims to bring down the cost of production to nearly zero and return to a pre-green revolution style of farming.

The pattern followed here is:

Similarly,

Hence, AHPSXMZD is the correct answer.

CONCEPT:

• Semiconductor: The material which is not a good conductor or a good insulator is called a semiconductor.
  • For example: Silicon, Germanium, etc
• Intrinsic semiconductor: The pure form of semiconductor is called an intrinsic semiconductor.
• Extrinsic semiconductor: The impurity atoms added are called dopants and semiconductors doped with the impurity atoms are called extrinsic or doped semiconductors.

  • P-type semiconductor: The semiconductor having holes as majority charge carriers and electrons as a minority charge carrier is called as P-type semiconductor.

  • N-type semiconductor: The semiconductor having electrons as majority charge carriers and holes as a minority charge carrier is called as N-type semiconductor.

EXPLANATION:

• ​From the above discussion, we can say that electrons are the major charge carriers in n-type semiconductors.

• Elements of Group 5 have five valence electrons, i.e. 1 extra from the Group 4 elements.
• 4 out of 5 electrons get bonded with the neighboring Silicon atoms and 1 electron per atom remains extra with the Group 5 elements.

The correct answer is Aravali Ranges.

• The oldest fold mountain ranges in the world is Aravali Ranges.

Key Points

• Aravalis are one of the world’s oldest fold mountains running in north-east to south-east direction from Delhi to Palampur in Gujarat. 
• It is an example of the relict mountain.
• Guru Shikhar is the highest peak of Aravali.
• The Aravalli Range dates back to times when the Indian Plate was separated from the Eurasian Plate by an ocean. 
• Three major rivers and their tributaries flow from the Aravalli, namely Banas, Sahibi and Luni.

Additional Information

• The Western Ghats are locally known by different names such as Sahyadri in Maharashtra, Nilgiri hills in Karnataka and Tamil Nadu and Annamalai hills, Cardamom hills in Kerala.
• The Himalayas are young fold mountains of the tertiary period, which were folded over the Tethys Sea due to inter-continental collision.
• They stretch from the Indus River in the West to the Brahmaputra River in the East.
• The Alps are the highest and most extensive mountain range system that lies entirely in Europe, and stretch approximately 1,200 km.

The correct answer is Leaves.

​

Food is stored in the leaves. Onion as a whole is a modified stem

Key Points

• Different parts of plants like roots, shoots, leaves, flowers, fruits, etc perform the function of storage of food 
• The fleshy leaves of onion are its consumable part.
• As a whole, the onion is a bulb, which is a short modified form of a stem that is surrounded by these fleshy leaves that store food for the onion shoots.

Important Points

• The stored food in onion leaves is Sugar.

Additional Information

• In plants like carrot, reddish, beetroot, sweet potato, turnip, etc. roots perform the function of food storage.
• Some plants store their food in the form of fruit. Ex- apple, guava, grapes mango, etc.
• Plants like potato, ginger, garlic, sugarcane, etc. store their food in stems.​
