  • Mukundara Hills National Park is a national park in Rajasthan with an area of 759.99 km².
  • It was established in 2004 and consists of three wildlife sanctuaries: Darrah Wildlife Sanctuary, National Chambal Sanctuary, and Jawahar Sagar Wildlife Sanctuary.
  • It is located in the Kathiawar-Gir dry deciduous forests. 
  • 1955 – Darrah was declared a wildlife sanctuary.
  • 2004 – Declared as Mukundra Hills National Park.
  • 2013 – Got approval from NTCA & declared as Tiger Reserve.
  • 2020 – Moefcc notifies MHTR Eco-Sensitive Zone

​Additional Information

• About Rajasthan Wildlife
  • ​Rajasthan has Ranthambore National and Sariska National Park and Mukundara as a tiger reserve.
  • The UNESCO World Heritage Site Keoladeo National park along with Tal Chhapar, Van Vihar, and Jorbeed are for bird destinations in the state.
  • The Desert National Park is home to the critically endangered species of Great Indian Bustard.

The correct answer is Cell.

Key Points

• Cell:
  • A cell is the smallest unit capable of independent existence which can reproduce itself. Hence, Option 3 is correct.
  • All living organisms, except for viruses, are composed of one or more cells.
  • Single-cell organisms; such as, bacteria, protozoa, and other micro-organisms are termed unicellular, while plants and animals that contain many cells are termed multicellular.
  • Highly complex organisms; such as, human beings consist of billions of cells, all of which are adapted to carry out specific functions; for example, groups of these specialized cells are organized into tissue and bodily organs.
  • Although cells may differ widely in size, appearance, and function, their essential features are similar.

​

Important Points

• Almost all cells perform biochemical processes, generate and process energy, and store genetic information to be passed down to future generations of cells.
• Advanced single-celled and multicelled organisms have nuclei that carry the DNA, primitive cells; such as, bacteria, have no nucleus and carry their DNA loosely in coils throughout the cells
• The number of cells in an organism varies; for example, bacteria are single-celled organisms; the average adult human body has about one hundred trillion cells.
• Cells are the structural unit of all organisms and come in a range of sizes and shapes.
• Animal cells contain only an outside cell membrane.
• In most fungi, bacteria, and plants; there is a rigid cell wall outside the membrane.
• Each cell is composed of a mass of jelly-like substance called the cytoplasm, surrounded by a membrane.

Additional Information

The correct answer is Plotter.

• The plotter is an output device producing continuous lines of different colours.

​Key Points

• Plotter
  • ​The plotter is used to draw Continuous lines.
  • A plotter is a printer that reads commands from a computer to make line drawings on paper with one or more automated pens.
  • The plotter can draw continuous point-to-point lines directly from vector graphics files or commands.
• There are a number of different types of plotters:
  • A drum plotter
    • Draws on paper wrapped around a drum which turns to produce one direction of the plot, while the pens move to provide the other direction.
  • A flatbed plotter
    • It draws on paper placed on a flat surface.
  • An electrostatic plotter
    • It is used to draw on negatively charged paper with positively charged toner.

Additional Information

• Daisy wheel printing 
  • It is an impact printing technology invented in 1970 by Dr. Andrew Gabor.
  • Used for high-quality text printing.
• Chain Printer
  • An early line printer that used type slugs linked together in a chain as its printing mechanism.
  • The chain spins horizontally around a set of hammers.
  • When the desired character is in front of the selected print column, the corresponding hammer hits the paper into the ribbon and onto the character in the chain.
