GRAP Stage 3 entails a ban on non-essential construction work. Classes up to grade V are required to shift to hybrid mode under Stage 3. Parents and students have the option to choose online education wherever available.
Under Stage 3, the use of BS-III petrol and BS-IV diesel cars (4-wheelers) is restricted in Delhi and nearby NCR districts. Persons with disabilities are exempt.
Stage 3 also bans non-essential diesel-operated medium goods vehicles with BS-IV or older standards in Delhi. The Stage 3 of GRAP was lifted on December 27 after a marked improvement in Delhi’s air quality following day-long rainfall in the national capital.
Throughout 2024, Delhi recorded the highest number of ‘severe’ AQI days since 2022, with 17 days exceeding an AQI of 400. Additionally, 70 days were classified as ‘very poor’. Not a single ‘good’ air quality day was recorded in 2024, a first since 2018.

The building blocks of proteins are amino acids, which are small organic molecules. Amino acids are linked together by peptide bonds to form long chains called polypeptides. Many polypeptides join to form a protein. The sequence of amino acids in a protein is called its primary structure. Proteins aRead more

Proteins are important for many functions in the body, including:
Structural elements: Proteins provide many of the structural elements of a cell and help bind cells together into tissues
Chemical reactions: Proteins catalyze most of the chemical reactions that occur in a cell
Transport: Proteins transport nutrients
Hormones and enzymes: Proteins function as hormones and enzymes
What are the different types of chemical bonds?
A chemical bond is a force of attraction between atoms or ions. Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions.The four major types of chemical bonds are: Ionic bonds FoRead more
A chemical bond is a force of attraction between atoms or ions. Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions.The four major types of chemical bonds are:
See lessIonic bonds
Form when one atom transfers electrons to another, creating oppositely charged ions. Ionic bonds are important for many processes in chemistry, including the development of batteries and the production of glass.
Covalent bonds
Form when atoms share electrons, creating electron pairs that surround the nuclei of the atoms. Covalent bonds are common in organic compounds, which contain carbon.
Metallic bonds
Form when electrons are shared between multiple metal atoms, creating a “sea of electrons” that orbits the nuclei of the atoms. Metallic bonds are strong, which explains why metals have high melting and boiling points, and are good conductors of heat and electricity.
Hydrogen bonds
Form when a hydrogen atom covalently bonded to an electronegative atom interacts with another electronegative atom. Hydrogen bonds are weak electrostatic bonds.
In reality, most materials have more than one type of bonding. For example, iron has mostly metallic bonding, but also some covalent bonding.

Heat us the degree of hotness or coldness of a body.The human body produces heat through a combination of processes, including:
See lessMetabolism
The body metabolizes food to produce heat through chemical reactions and cellular respiration. The liver is a major source of metabolic heat.
Muscle contractions
Involuntary muscle contractions, like shivering, increase muscle cell activity and create heat. Voluntary muscle exertion and motion also produce heat.
Cellular respiration
Cellular respiration produces energy in the form of ATP, which is used for daily activities and the excess is released as heat.
Thyroid hormones
The hypothalamus releases thyroid hormones, which increase metabolic rate and heat production.
Blood friction
The friction of blood against blood vessel walls produces heat.
The body’s temperature is usually between 98 and 110 degrees Fahrenheit. The body’s ability to generate heat helps it resist exposure to low temperatures.
