Teaching is not affected by socio-economic background of students and teachers. Teaching is impartial.

A lively classroom is the one having frequent student-teacher discussions. This is the two-way teaching method.

Scaffolding process in education is a teaching strategy to expedite children's learning process. Using this method, teachers first demonstrate how to deal a problem, then go back and offer support as and when required. Once basic learning is done, they give prompts, ask questions, cues to make the child learn and build the concept on what he has already learned.

To an observer on Earth the stars appear to twinkle. This is due to the fluctuation of physical conditions in the earth’s atmosphere.  Each single stream of starlight is refracted and is caused to change direction. This is because the light which passes the different layers of atmosphere differ in temperature and density. This causes the light from the star to twinkle when seen from the ground.

If the current passing through an electric heater has been halved then the heat produced will also be reduced to one fourth because H=I² RT.

We observe interference pattern when the size of the slits are comparable to the wavelength of light. But here, the size of the bulb is bigger than wavelength of light.

(1,750 x 40)/1000 = 70 kilowatt-hour.

Involving community members as learning resources in science education enhances the quality and relevance of the learning experience, fostering a deeper understanding and appreciation of science among students.

Key Points

• By involving the community in science education, students gain access to this wealth of local knowledge, which can deepen their understanding of scientific concepts and their practical applications in real-life contexts.
• Community members can provide hands-on learning opportunities by organizing field trips to local habitats, farms, or natural reserves.
• By connecting scientific concepts to local contexts, students are more likely to develop a personal interest in science and see its relevance to their own lives and communities.
• Involving community members in science education promotes community engagement and collaboration between schools and local stakeholders.

Hence, we can conclude that community involvement enriches the learning experience by incorporating local knowledge and practices.

Gallium and germanium were the elements whose place were left in Mendeleev's periodic table.

Bohr-Bury Scheme

According to Bohr’s model, electrons occupy certain stable orbits or shells. Each shell has a definite energy.
These orbits or shells are represented by the letters K, L, M, N… or the numbers 1, 2, 3, 4…
The maximum number of electrons present in the shell is given by the formula (2n2), where n is the orbit number or shell number.

During the electrolysis of brine, hydrogen gas is released at the cathode. This process is essential in the production of various chemicals, including sodium hydroxide and chlorine gas.

Carbon has the unique ability to form bonds with other atoms of carbon, giving rise to large molecules. This property is called catenation or self linking ability of carbon.

Law of conversation of mass:in a chemical reaction mass of reactants must be equal to the mass of products because atoms r neither created nor destroyed in a chemical reaction. This was proposed by Antoine lavoisier but experimentally proved by landolt.

CH₄(g)+2O₂(g)→CO₂(g)+2H₂O(g)+ Heat + Light

Unicellular organisms are made up of only one cell that carries out all the functions needed by the organism, while multicellular organisms use many different cells to function. Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions

The Thyroid Gland, located in the neck region, is responsible for secreting hormones like Triiodothyronine and Thyroxine. Thyroxine plays a key role in regulating the body's metabolism of glucose, proteins, and fats. Any imbalance in thyroid hormone levels can lead to metabolic issues affecting various bodily functions.

The Catla fish is an economically very important South Asian freshwater fish. It is in the carp family Cyprinidae.

The fish is mainly found in the rives and lakes in northern India, Bangladesh, Nepal, Pakistan and Myanmar.

To determine the order of animal food products based on their fat and protein content, we need to compare the three options - fish, egg, and meat - in each set. We are looking for the set that contains the animal food products in the order of more fats, more proteins, and least fat.
Let's analyze each set one by one:
Set A: Fish, Egg, Meat
- Fish: Generally low in fat and high in protein.
- Egg: Contains moderate amounts of fat and high-quality protein.
- Meat: Can vary in fat content depending on the type, but generally contains higher amounts of fat compared to fish and eggs.
Set B: Meat, Milk, Egg
- Meat: Can vary in fat content, but generally contains higher amounts of fat compared to milk and eggs.
- Milk: Contains moderate amounts of fat and protein.
- Egg: Contains moderate amounts of fat and high-quality protein.
Set C: Milk, Meat, Fish
- Milk: Contains moderate amounts of fat and protein.
- Meat: Can vary in fat content, but generally contains higher amounts of fat compared to milk and fish.
- Fish: Generally low in fat and high in protein.
Set D: Egg, Meat, Fish
- Egg: Contains moderate amounts of fat and high-quality protein.
- Meat: Can vary in fat content, but generally contains higher amounts of fat compared to eggs and fish.
- Fish: Generally low in fat and high in protein.
Based on the analysis, we can conclude that Set D: Egg, Meat, Fish contains the animal food products in the order of more fats, more proteins, and least fat among them.

Explanation:

The analogy can be understood as follows:

- A sculptor creates a statue
- A poet creates a verse

In both cases, the artist creates a piece of art. The sculptor works with physical materials to create a statue, while the poet uses words to create a verse. Therefore, the correct option to complete the analogy is "Verse" (Option C).
