All 6,650 villages in Jammu and Kashmir have achieved Open Defecation Free Plus Model status, making it the first union territory in India to do so. This is a significant achievement, as it means that all villagers now have access to safe and sanitary toilets and that greywater and solid waste are being managed effectively.

India along with 10 ASEAN Member States (AMS) were represented by 200 participants, at the 4th edition of the annual ASEAN India Grassroots Innovation Forum (AIGIF) that was launched in Langkawi, Malaysia.
The AIGIF is an annual programme focused on fostering a strengthened relationship between India and AMS on the premise of cooperation in Science, Technology and Innovation (STI). Department of Science & Technology (DST) and National Innovation Foundation (NIF) of India and the Science and Technology Ministry of the host nation, Malaysia collaborated for the event.

Age of learner is proportional to the cognitive ability of the learner, thus teaching aids should be selected on the basis of the age. Use of any kind of teaching aid can only be helpful in serving the purpose, if it runs parallel to the cognitive ability of the learner.
The use of teaching aids facilitates the objective of teaching by assisting teachers in differentiating instruction. Hence, they must be chosen keeping in view what the teacher intends to teach the students.
The teaching aids also must be carefully chosen to match the intellectual level of the students. In case of students with intellectual disabilities, different kind of teaching aids are to be used, instead of those used for normal intellectual abilities.

Psychologist Albert Bandura is the researcher most often associated with learning through observation. He and others have demonstrated that we are naturally inclined to engage in observational learning.

NRED in NEP 2020 aims to establish a centralized repository for educational data to aid research and policymaking.

NEP 2020 recognizes the role of school counselors in providing mental health support to students.

Affective motives deal with the need to reach satisfying feeling states and obtain personal goals. Maslow's theory deals with all types of needs. His Hierarchy of Needs Theory includes Psychological needs (food, air, water.) Safety needs (personal security, health.) Love and Belonging need (friendship, intimacy.) Esteem needs (respect, status.
Hence, this is the correct answer.

As per NEP 2020, adult education curriculum framework will be developed by a new and well-supported constituent body of the NCERT that is dedicated to adult education, so as to develop synergy with and build upon NCERT’s existing expertise in establishing outstanding curricula for literacy, numeracy, basic education, vocational skills, and beyond.

Key PointsThe curriculum framework for adult education will include at least five types of programmes:-

•  foundational literacy and numeracy
•  critical life skills (including financial literacy, digital literacy, commercial skills, health care and awareness, child care and education, and family welfare)
• vocational skills development (with a view towards obtaining local employment)
•  basic education (including preparatory, middle, and secondary stage equivalency)
•  continuing education (including engaging holistic adult education courses in arts, sciences, technology, culture, sports, and recreation, as well as other topics of interest or use to local learners, such as more advanced material on critical life skills).

Thus, it is concluded that As per NEP-2020, the responsibility to develop the Adult Education Framework has been given to NCERT.

'Wrong' answers of students should be corrected by the teachers during class discussions as children should be encouraged to express themselves without fear of being incorrect.

• The range of bacteria or other microorganisms that are affected by a certain antibiotic is expressed as its spectrum of action.
• Antibiotics that kill or inhibit a wide range of Gram-positive and Gram-negative bacteria are said to be broad-spectrum antibiotics.
• Chloramphenicol,Vancomycin and ofloxacin are important broad-spectrum antibiotics.

75% completion means 2 half lifes so 50% completion means only one half life.

In acid catalysed aldo! condensation, enol acts as a nucleophile.

• Concept of electrons moving in a circular path of fixed energy called orbits was put forward by Bohr and not derived from Rutherford's scattering experiment.
• Out of a large number of circular orbits theoretically possible around the nucleus.
• The electron revolves only in those orbits which have a tired value of energy Hence, these orbits are called energy level or stationary states.

The correct answer is option c

The above product is meso form of an isomer which is a type of stereoisomer that possesses an internal plane of symmetry. This symmetry leads to identical or equivalent substituent groups on either side of the plane, resulting in an overall non-chiral (achiral) molecule. Despite having stereocenters, the meso form does not exhibit optical activity because any rotation around the internal plane of symmetry can interconvert its mirror-image configurations, making them superimposable.

Sodium saccharin (benzoic sulfimide) is an artificial sweetener with effectively no food energy. It is about 300–400 times as sweet as sucrose but has a bitter or metallic aftertaste, especially at high concentrations. Saccharin is used to sweeten products such as drinks, candies, cookies, and medicines.

(b) Unit cell of fee is divided into eight small cubes. Each cube has four atoms at alternate positions. When joined to each other, they make a regular tetrahedron.
Thus, number of tetrahedral void in small cube = 1 and in eight cubes, voids = 8.

Note  If number of atoms in a cube = N, then, number of octahedral voids = N and number of tetrahedral voids = 2N

The correct answer is option A
Reduction with LiAlH₄

 

Radial nodes = (n - l - 1)
Angular nodes = l, total nodes = (n - 1), nodal plane = l

Aloxy mercuration - demercuration brings about Markownikoff’s addition of alcohols at   without any rearrangement.

The electron has minimum energy in the first orbit and its energy increases as n increases. Here n represents number of orbit, i.e. 1st, 2nd, 3rd .... The third line from the red end corresponds to yellow region i.e. 5. In order to obtain less energy electron tends to come in 1st or 2nd orbit. So jump may be involved either 5 → 1 or 5 → 2.

The correct answer is option A
Nucleotides are joined together by phosphodiester linkage between 5′ and 3′ carbon atoms of pentose sugar.
 

The physical properties of isotopes of the same element are not identical because the atomic mass and mass number differ. This affects physical properties such as density and temperature of change of state, eg. boiling and melting point.

The correct answer is option B
Calcitriol , is the hormonally active metabolite of vitamin D  which has three hydroxyl groups.Calcitriol increases the level of calcium  (Ca2+) in the blood  by increasing the uptake of calcium from the gut  into the blood, increasing reabsorption of calcium by the kidneys, and possibly increasing the release of calcium into the blood from bone. Vitamin D has a significant role in calcium homeostasis  and metabolism. Its discovery was due to effort to find the dietary substance lacking in children with rickets  (the childhood form of osteomalacia).

Liquid in liquid sols are emulsions

The correct answer is Option C.
Unit of rate of reaction =sec⁻¹

∴ Units of K1 = sec⁻¹

∴ Unit of K₂ = M⁻¹sec⁻¹

PCl₅ dissociation a closed container

Reductive Ozonolysis of alkene forms aldehyde or ketone.

Butylated hydroxy toluene (BHT) is used as an antioxidant. It retards the action of oxygen on the food material and thereby helps in preventing oxidative rancidity of fats.It itself get oxidized and prevent the food.
