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.

Here, all except Nohkalikai are names of different diseases while ‘Nohkalikai’ is a waterfall in India.

The correct answer is Udaipur.

• Gulab Bagh (also known as Sajjan Niwas Garden) is located in Udaipur.

Key Points

• Gulab Bagh:

  • It also houses a museum called Victoria museum.
    • The museum is now called Saraswati Bhawan Library.
  • 

The correct answer is X-Ray.

• Electromagnetic (EM) radiation includes radiation via radio waves, microwaves, X-rays and gamma rays.

Key Points

• Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms.
• Electromagnetic (EM) radiation includes radiation via radio waves, microwaves, X-rays and gamma rays.
• Sunlight is also a form of EM energy.

​Additional Information

• ​EM radiation spans an includes a range of wavelengths and frequencies.
• This range is known as the electromagnetic spectrum.
• The EM spectrum is generally divided into seven regions:
  • Radio waves,
  • Microwaves,
  • Infrared (IR),
  • Visible light,
  • Ultraviolet (UV),
  • X-rays,
  • Gamma rays.

Important Points

• Radio waves have the longest wavelength.
• Gamma rays have the shortest wavelength.

The correct answer is Ethanol + Methanol​.

• Ethanol + Methanol​ is denatured alcohol.
• Denatured alcohol is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption.
• The term denatured alcohol refers to alcohol products adulterated with toxic and/or bad tasting additives (e.g., methanol, benzene, pyridine, castor oil, gasoline, isopropyl alcohol, and acetone), making it unsuitable for human consumption.
• The most common additive used is methanol (5–10%), giving rise to the term methylated spirits. Denatured alcohol is used as a lower-cost solvent or fuel for home-scale or industrial use.

Key Points

• Denatured alcohol is ethanol or grain alcohol that contains additional chemicals called denaturants that make it unfit for human consumption.
• Denatured alcohol is fine for some types of lab work and as an ingredient in certain products, but it's not safe to drink.
• Ethanol is an organic chemical compound. It is simple alcohol with the chemical formula C₂H₆O.
• Its formula can be also written as CH₃−CH₂−OH or C₂H₅OH and is often abbreviated as EtOH.

Additional Information

• Alcohol (ethanol or ethyl alcohol) is the ingredient found in beer, wine, and spirits that causes drunkenness.
• Alcohol is formed when yeast ferments (breaks down without oxygen) the sugars in different food.
