 Indus Valley Civilization

• Indus Valley Civilization was one of those early urban civilizations that were originated in 2300 BC and were developed in the river basins of Sutlej, Ravi, and Indus.
• Indus Valley Civilization peoples cultivate many crops such as Barley, Wheat, Melon seeds, and oil crops like Sesame, Mustard, and Dates. These were traded by farmers with other people. 
• The most typical Indus seal is square, with a set of symbols along the top, an animal in the centre, and one or more symbols at the bottom.  

Seals

• The unicorn is the most common motif on Indus seals and appears to represent a mythical animal that Greek and Roman sources trace back to the Indian subcontinent. A relatively long inscription of eight symbols runs along the top of the seal. Hence option 3 is correct.

• Archaeologists have discovered thousands of seals, mostly made of steatite, and occasionally of agate, chert, copper, faience and terracotta, with beautiful figures of animals, such as unicorn bull, rhinoceros, tiger, elephant, bison, goat, buffalo, etc.
• The realistic rendering of these animals in various moods is remarkable. The purpose of producing seals was mainly commercial.
• It appears that the seals were also used as amulets, carried on the persons of their owners, perhaps as modern-day identity cards. The standard Harappan seal was a square plaque 2×2 square inches, made from steatite.
• Every seal is engraved in a pictographic script which is yet to be deciphered. Some seals have also been found in ivory.
• They all bear a great variety of motifs, most often of animals including those of the bull, with or without the hump, the elephant, tiger, goat and also monsters.

Key Points 

• The biosphere reserves are the areas meant for the conservation of biodiversity.
• These are large areas of protected land for the conservation of wildlife, plant and animal resources and traditional life of the tribals living in the area.
• The biosphere reserves help to maintain the biodiversity and culture of that area.
• A biosphere reserve may also contain other protected areas.
• The Pachmarhi Biosphere Reserve consists of one national park named Satpura and two wildlife sanctuaries named Bori and Pachmarhi

The Correct Answer is Cytokinin.

Key Points

• Cytokinins are a class of plant growth substances (phytohormones) that promote cell division or cytokinesis in plant roots and shoots.
• There are two types of Cytokinins: Adenine-type Cytokinins represented by Zeatin, Kinetin and 6-Benzylaminopurine and Phenylurea-type Cytokinins like Diphenylurea and Thidiazuron (TDZ).

Key Points 

• Auxins are a class of plant hormones with some morphogen-like characteristics. Auxins play a cardinal role in the coordination of many growths and behavioural processes in plant life cycles and are essential for plant body development.
• Abscisic acid is a plant hormone. ABA functions in many plant developmental processes, including seed and bud dormancy, the control of organ size and stomatal closure.
• Gibberellins are plant hormones that regulate various developmental processes, including stem elongation, dormancy, germination, flowering, flower development and leaf and fruit senescence.
