Design Principles for Screens:
- Screens use design principles that are similar to those used for printed reports.
Explanation:
- While designing screens, the same principles that are applied to printed reports are often used. This is because both mediums aim to convey information effectively and efficiently to the user or reader.
Reasons why the principles are similar:
1. Consistency: Both screens and printed reports benefit from a consistent design to ensure a cohesive and familiar experience for the user or reader. Consistency in layout, typography, color schemes, and imagery helps to establish a visual hierarchy and aids in comprehension.
2. Clarity: Clear and concise communication is essential in both screens and printed reports. Information should be presented in a logical and organized manner, with attention to readability, legibility, and the use of appropriate visuals.
3. Visual Hierarchy: Both screens and printed reports require a well-defined visual hierarchy to guide the user or reader's attention. Important information should stand out through the use of size, color, typography, and placement to ensure key messages are easily understood.
4. Usability: Screens and printed reports need to be user-friendly and intuitive. The design should consider the target audience, their needs, and the context in which the information will be consumed. Navigation, labeling, and the overall user experience are crucial in both mediums.
5. Accessibility: Both screens and printed reports should be designed with accessibility in mind. This includes considerations for individuals with visual impairments, color blindness, or other disabilities. Use of appropriate contrast, alternative text, and other accessible design practices are important in both mediums.
In conclusion, while there may be some differences in the implementation and specific considerations between screens and printed reports, the underlying design principles remain similar. Both mediums aim to effectively convey information and provide a positive user or reader experience.

All the statements are correct. Black board is a primary teaching aid in a classroom. It makes the subject interesting for pupils. It also simplifies the tough topics and keeps the pace of the lecture moderate as it encourages writing while talking and hence making teaching effective.

The new education policy must provide to all students, irrespective of their place of residence, a quality education system, with a particular focus on historically marginalized, disadvantaged, and underrepresented groups.

Key Points National Education Policy (NEP) 2020 recommends the study of classical languages as a language as an additional option.

• In addition to Sanskrit, other classical languages and literature of India, including Tamil, Telugu, Kannada, Malayalam, Odia, Pali, Persian, and Prakrit, will also be widely available in schools as options for students, possibly as online modules, through experiential and innovative approaches, to ensure that these languages and literature stay alive and vibrant.
• The NPE (1986) noted that the regional languages are already in use at the primary and secondary stages.
• At the secondary stage, the State Governments should adopt and vigorously implement the three-language formula which includes the study of a modern Indian or classical language, preferably one of the southern languages, apart from Hindi and English in the Hindi speaking States, and of Hindi along with the regional language and English in the non-Hindi speaking States.

Thus, it is concluded that National Education Policy (NEP) 2020 recommends the study of classical languages as an additional option.

72.f = - 0.2 m, v = + 0.3 mThe lens formula 1v - 1u = 1f
 1u = 1v - 1f = 10.3 + 10.2
   = 0.50/006 
u = 0.12 m

For a spherical mirror focal length is one half of its radius of curvature i.e. f = R/2 or R = 2f

We know; P = mv
If m = 2 m ;   v= v/2

Chapter 7 of National Education Policy 2020 covers the whole gamut of Efficient Resourcing and Effective Governance through School Complexes/Clusters.

Efficient Resourcing and Effective Governance through School-

• The average number of students per grade in the elementary schooling system (primary and upper primary, i.e., Grades 1–8) is about 14, with a notable proportion having below 6; during the year 2016–17, there were 1,08,017 single-teacher schools, the majority of them (85743 ) being primary schools serving Grades 1–5.
• The small school sizes have rendered it economically suboptimal and operationally complex to
  run good schools, in terms of deployment of teachers as well as the provision of critical physical
  resources.
• The challenges faced by the large numbers of small schools will, by 2025, be addressed by State/UT governments by adopting innovative mechanisms to group or rationalize schools. The objective behind this intervention would be to ensure that every school has:
  • adequate number of counselors/trained social workers and teachers (shared or otherwise) for teaching all subjects including art, music science, sports, languages, vocational subjects, etc;
  • adequate resources (shared or otherwise), such as a library, science labs, computer labs, skill labs, playgrounds, sports equipment and facilities, etc.;
  • a sense of community is built to overcome the isolation of teachers, students, and schools, through joint professional development programs, sharing of teaching-learning content, joint content development, holding joint activities such as art and science exhibitions, sports meets, quizzes and debates, and fairs;
  • cooperation and support across schools for the education of children with disabilities; and
  • improved governance of the schooling system by devolving all finer decisions, to Principals, teachers, and other stakeholders within each group of schools and treating such a group of schools, which range from the foundational stage through the secondary stage, as an integrated semi-autonomous unit
• The innovative mechanism to group or rationalize schools would be the establishment of a grouping structure called the school complex, consisting of one secondary school together with all other schools offering lower grades in its neighborhood including Anganwadis, in a radius of five to ten kilometers.
• Every State will be encouraged to strengthen existing or establish “Bal Bhavans” where children of all ages can visit once a week (e.g., on weekends) or more often, as a special daytime boarding school, to partake in art-related, career-related, and play-related activities.
• To enhance cooperation and positive synergy among schools, including between public and private schools, the twinning/pairing of one public school with one private school will be adopted across the country, so that such paired schools may meet/interact with each other, learn from each other, and also share resources.

Hence, we can conclude that "Separating the public and private schools for less cooperation further reducing the synergy between them" is not a proposed step towards effective governance for efficient use of resources.

A chemical reaction involves the breaking and forming of chemical bonds. In the methane reaction above, bonds are broken in methane and oxygen, and bonds are formed in carbon dioxide and water. A reaction like this, in which a compound or element burns in oxygen, is called a combustion reaction. 
CH_₄[gas] + 2O_₂[gas] → CO_₂[gas] + 2H_₂O[steam] + 891kJ

It is a single replacement reaction. 
Mg + 2HCl → MgCl₂  + H₂ 

The Golgi apparatus links carbohydrates with proteins coming from ER to form glycoproteins. This process is called glycosylation. Golgi complex brings about membrane transformation, that is, converting one type of membrane (e.g., that of ER) into other types (e.g., selectively permeable plasma membrane, differentiated membrane of lysosome). This complex also takes part in the recycling of plasma membrane. The Golgi complex modifies, sorts and packages proteins and lipids coming from the ER. Packaging involves wrapping the material by a membrane, forming secretory vesicles. The secretory vesicles pinch off from the ends of the cisternae and appear as dense secretory or zymogen granules in the cytoplasm. Later, these vesicles release their secretions by exocytosis or revere pinocytosis.

Site of protein synthesis is ribosomes.

So, the correct answer is 'Ribosomes'.

Pituitary gland is called master gland because it controls the secretion of all other endocrine glands.

The DNA in the nucleus of a cell is the information source for making proteins. If the information is changed, different proteins will be made.

During formation of gametes meiosis occurs resulting in exchange of genes by the process of crossing over.

"The Sun has been radiating an enormous amount of energy at the present rate for nearly 5 billion years and will continue radiating at that rate for about 5 billion years more. Only a small part of solar energy reaches the outer layer of the earth’s atmosphere. Nearly half of it is absorbed while passing through the atmosphere and the rest reaches the earth’s surface."

One significant physical change experienced by girls during puberty is breast enlargement. This is a result of the development of mammary glands and the accumulation of fatty tissue in the breasts. It is a normal part of female sexual maturation and a key characteristic of this phase.
