Question Discussion & Solution

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 Element.

Key Points

• An electric room heater or an electric heater used for cooking contains a coil of wire.
• The coil of wire used in electric heaters is called a heating element.
• The heating coil of the electric room heater transfers the electric energy into heat energy.
• The elements become red hot and give out heat after connecting to the electric supply.
• The amount of heat produced in a wire depends on its material used, length, and thickness.
• The coil of the electric heater is made up of nichrome.
• Nichrome consists of 80% nickel, 20% chromium.

Additional Information

• The filament is usually made of very thin tungsten wire.
  • In an incandescent bulb, an electric current is passed through a metal filament.
• A cell is a single unit device that converts chemical energy into electric energy.
  • It produces electricity capable to run smaller appliances.
• A battery usually consists of a group of cells.

Mistake Points

• A filament is a fine resistance wire the purpose of which is to emit white light. 
• An element is a resistive wire the sole purpose of which is to produce heat.

The correct answer is Kalology.

Key Points

• The study of human beauty is called Kalology.
  • Kalology is the study of beauty and the ways in which beauty influences society.
  • This study is focused primarily on human attractiveness, rather than the broader field of aesthetics, and was popularized during the 19th century when philosophers attempted to codify beauty and create a uniform system for evaluating it.
  • A scale was even proposed, probably jokingly, which rated beauty in terms of the theoretical beauty of Helen of Troy, who allegedly had a face to launch 1,000 ships.

The correct answer is Dhaka.

Key Points

• All India Muslim League was established On 30 December 1906, a conference took place under the control of Nawab Salim Ulla Khan of Dhaka.
• The constitution of this league was made in 1907 in Karachi Pakistan.
• Its first session was held in 1907 in Karachi.
• The first session of the All India Muslim League was presided over by Aga Kha.
• Muslim League supported the partition of Bengal.

Important Points

• The partition of Bengal in 1905 was introduced by Lord Curzon.
• He issued the order of partition of Bengal in July 1905 and the partition took effect from October 1905.
• The Eastern part of Bengal has the majority of the Muslim population and the western part of Bengal has the majority of the Hindu population while the central region is comprised of both religions.
• The partition of Bengal was made in order to carry out effective administration and to discourage Hindu and Muslim unity.
• River Bhagirathi served as a physical partitioner between East Bengal and West Bengal.
