Question Discussion & Solution

The correct answer is All of the above.

Key Points

• Living organisms share characteristics such as the ability to move and reproduce.
• There are different types of living organisms including plants, animals, fungi, bacteria, and protoctists.
• Characteristics of living organisms:
  • Movement - they can move and change their position.
  • Reproduction – they can make more of the same kind of organism as themselves.
  • Sensitivity – they can detect or sense stimuli and respond to them.
  • Growth - they can permanently increase their size or dry mass by increasing the number or size of their cells.
  • Respiration – they can create chemical reactions that break down nutrient molecules in living cells to release energy.
  • Excretion – they can excrete toxic materials, waste products of metabolism, and excess substances.
  • Nutrition - they can take in and absorb nutrients such as organic substances and mineral ions. These nutrients contain the raw materials or energy needed for growth and tissue repair.

  Additional Information

• Cells are the building blocks of every living organism.
• Two-thirds of a cell is composed of water and is made up of biological molecules such as proteins and lipids.
• They provide a definite structure to the body, help to break down food, and release energy which is used up by our body to perform multiple tasks throughout the day.

The correct answer is Lunkaran.

Key Points

• Lunkaran -
  • He was the son of Jaitra Singh II.
  • He had 9 sons and 3 daughters.
  • He organized the Jaitbandh Yagya and invited Bhati who accepted the Muslim religion for its purification.
  • He made Amir Ali Khan, the Pathan of Kandahar, the turban-changer brother.
  • Amir Ali Khan betrayed him and attacked the fort.
  • Half of the Saka took place during his reign, where men committed saffron but women did not commit Jauhar because of their murder.

Additional Information

• Mulraj I -
  • He was the son of Jaitsi Singh I.
  • Due to a shortage of food items, he decided to perform Saaka.
  • Jaisalmer's first Saaka happened in his reign.
• Ghadsi -
  • He was the son of Ratan Singh.
  • He regained Jaisalmer state from Alauddin Khilaji.
  • He built Ghadsisar pond in Jaisalmer.
• Vijayraj II -
  • He was the son of Dusaj.
  • He was married to Chalukya king Singhraj's daughter.
  • He defeated the king of Uttarpradesh at the request of his mother-in-law.
  • He received the title of Uttar Bhad Kiwad.

The correct answer is 10.

• In India, the census is done after a gap of 10 years.

Key Points

• In 1872 AD, the first Census was done in India under the rule of Lord Mayo.
• The First Official Census in India was done in 1881 AD under Lord Rippon.
  • It was called First synchronised census.
• Since 1901, it has been taking place every decade.
• Census 2011, is the 15th census and 7th after independence.
• The slogan of Census 2011 is “Our Census, Our Future”.
• India was the first country to adopt family planning in the world.

The correct answer is Flash memory.

Key Points

• Flash memory is a type of memory that functions similarly to RAM and ROM.
• You can write data to flash memory just like you can to RAM, however, unlike ROM, the data isn't lost when the power is turned off. Read-only memory is referred to as ROM.
• Although the CPU can read from ROM, it cannot write to or modify it. ROM is a long-term storage medium.
• Random-access memory (RAM) refers to memory that the microprocessor can read from and write to. It's done in RAM when you construct something in memory.

Important Points

• The smallest and fastest memory in a computer is register memory.
• External memory, often known as secondary memory, refers to the numerous storage media that a computer might use to store data and applications.
• Cache memory, often known as cache, is a supplementary memory system that saves frequently used instructions and data in order for the central processing unit (CPU) of a computer to perform them more quickly.

Energy is a phenomenon which is transferred from one object to another in the form of heat, as a result, it performs work. When the energy is transferred from one object to another, it changes its form and this phenomenon is called conservation of energy. The following types of energy are discussed below:

• Solar Energy: It is the energy that is derived from the sun. When solar cells are exposed to the sun, it converts solar energy in electrical energy. Important facts related to the solar energy:
  • India ranks 5^th globally in the installed Solar Energy.
  • India has about 34.5 GW installed solar capacity at present.
  • Ndia targes 175 GW of renewable energy by 2022.
• Chemical Energy: It is the energy that is released when a chemical reaction takes place. Its applications are in the creation of energy in our body, photosynthesis, electric cells.
• Nuclear Energy: This energy is either produced by nuclear fusion or nuclear fission. Nuclear fusion is a process when two nuclei are combined to release energy while nuclear fission is a process in which a single nucleus breaks into two parts to release energy.
• Magnetic Energy: Energy caused by the production of the magnetic field is called magnetic energy. This energy is used in making electrical bells, electric motors and generators.

Hence, we conclude that solar energy causes solar energy to transform electrical energy.
