Verbs are the action words in a sentence that describe what the subject is doing. A verb is a doing word that shows an action, an event, or a state. In other words, a verb is a word that informs about action, the existence of something, or an occurrence. In our sentence, the soil is the subject and accumulation is the action. Thus, accumulate is a verb.

• A noun is a word that names something (such as a person, animal, place, thing, quality, or idea) and is typically used in a sentence as the subject or object of a verb or a preposition.
  Ex: Johnny Depp acted brilliantly in the movie Edward Scissorhands.
• ​An adverb is a word that describes or gives more information about a verb, adjective, adverb, or phrase.
  Ex: Walk carefully lest you should fall.​
• Conjunctions are the words used to connect two words or clauses or sentences.
  ​Ex: John David Washington and Robert Pattinson starred in Christopher Nolan-directed thriller Tenet. 

It is the ear, not the eye, which is the true test of verse for when verse is read aloud, it sounds different from prose.

The Direct Method emphasizes the use of the target language in the classroom and focuses on developing oral proficiency.

• In this method, the learning process starts with listening, as students are exposed to authentic spoken language in the target language.
• They then move on to speaking, practicing and producing the language through oral communication activities.
• Reading skills are introduced next, allowing students to comprehend written texts in the target language.
• Finally, writing skills are developed, enabling students to express themselves in written form.
• This sequence reflects the natural progression of language acquisition, mirroring the way children acquire their first language.
• By prioritizing listening and speaking at the early stages, the Direct Method aims to develop communicative competence and fluency before moving on to reading and writing, which involve more complex language structures and skills.

Hence , it is clear that the order of learning language skills in the Direct Method of Language Teaching is Listening, speaking, reading, writing.

"The focus is on using the language rather than analysis of the language and grammar is taught implicitly rather than explicitly." This is Communicative approach of teaching the language.
The communicative approach is based on the idea that learning a language successfully comes through having to communicate real meaning. When learners are involved in real communication, their natural strategies for language acquisition will be used, and this will allow them to learn to use the language.

A conducive language classroom environment catering to the needs and interests of young children is an important factor for leading programs and activities in the pre-school class. A carefully planned environment can help preschoolers feel calm and secure, while at the same time, engaged and inquisitive.

Proficiency Test measures how well an individual has mastered a language. It is the ability of a person that transfers meaning in production and comprehension to use language with a level of accuracy.
Aim of the Language Proficiency Test:

• It determines the level of accuracy in a specific language.
• It determines a person's knowledge in the whole language, like knowledge, speaking, and writing skills.
• It evaluates how well an individual can use language to communicate in daily life.
• It must be reliable, valid, and easy to understand to test the level of learner's language skills to make them proficient in communication.
• It is an important tool to test the level of learner's language skills to make them proficient in communication.
• Language proficiency tests are considered to evaluate people’s skills in a language.
• To enhance student’s academic skills.

Examples of Proficiency Tests-

• International English Language Test System (IELTS)
• Test of English as a Foreign Language (TOEFL)

So, from the above-mentioned points, it becomes clear that the basic requirement of a language proficiency test is that it must be reliable.

a = ((2013)² + 2013 + 2014)^1/2
= ((2013)² + 2013 + 2013 + 1)^1/2
= ((2013)² + 2 x 2013 x 1 + 12)^1/2
= ((2013 + 1)²)^1/2
= ((2014)²)^1/2 = 2014
Thus, option (4) is correct.

The radiation dose absorbed by a person (that is, the amount of energy deposited in human tissue by radiation) is measured using the conventional unit 'rad' or the SI unit 'gray (Gy)'. The biological risk of exposure to radiation is measured using the conventional unit 'rem' or the SI unit 'Sievert (Sv)'.

Given:
The HCF of 1683, 2244 and 5049 is x.
Concept used:
HCF - The greatest number which divides each of the two or more numbers
Calculation:
⇒ 1683 = 3 × 3 × 11 × 17
⇒ 2244 = 2 × 2 × 3 × 11 × 17
⇒ 5049 = 3 × 3 × 3 × 11 × 17
The HCF = (3 × 11 × 17)
⇒ 561
So,
⇒ x = 561
Now,
The sum of digits of x = (5 + 6 + 1)
⇒ 12
∴ The required sum of digits of x is 12.

Ecosystem: 

• All organisms such as plants, animals, microorganisms, and human beings as well as the physical surroundings interact with each other and maintain a balance in nature.
• All the interacting organisms in an area together with the non-living constituents of the environment form an ecosystem.

Autotrophs are organisms that can produce their own food, using materials from inorganic sources by using basic energy sources such as sunlight.

• Plants are the main example of autotrophs, using photosynthesis.
• Some autotrophs, such as green plants and algae, are phototrophs, they convert electromagnetic energy from sunlight into chemical energy in the form of glucose. So, Spinach, Tomato, Banana are also examples of autotrophs.

Mode of Nutrition:

Autotropic: The mode of nutrition in which organisms make food themselves from simple substances is called autotrophic (auto = self; trophos = nourishment) nutrition. Therefore, plants are called autotrophs. Ex- Plants, Tress, algae, etc.
Heterotrophic: Animals and most other organisms take in ready-made food prepared by the plants. They are called heterotrophs (heteros = other).

• Holozoic: Animals who take in solid food and breakdown it inside their body like animals, amoeba, etc. comes under the holozoic mode of nutrition.
• Parasitic: Parasites live inside or outside the other organism (host) and get their nutrition from the host. Ex - Ticks, Cuscuta (dodder), mosquito, etc.
• Saprophytic: In this mode of nutrition the organisms take in nutrients in solution form from dead and decaying matter is called saprotrophic nutrition. Ex- Fungi grows on pickles, leather, etc.

Hence, Carbon dioxide and water, sunlight, chlorophyll all are correct.

Heredity is a term that refers to traits and features that are inherited from one's parents and ancestors. At birth, a person inherits 50% of each parent's genetic material (genes) that are passed along through the chromosomes found in the DNA. DNA (deoxyribonucleic acid) is the cell's genetic material, contained in chromosomes within the cell nucleus and mitochondria. A chromosome contains many genes.

Given:
One bell rings every 6 minutes. Another bell rings every 8 minutes. The third bell rings every 9 minutes. 
Concept used:
LCM is the smallest common multiple of two or more numbers.
Calculation:
Now, the three bells will ring together after
⇒ LCM (6, 8, 9)
⇒ 23 × 32
⇒ 8 × 9
⇒ 72 minutes
∴ The three bells will ring together after 72 minutes.

The correct answer is i - d, ii - c, iii - b, iv - a

Plant Cell

• The cell wall in plant cells is made up of cellulose, a carbohydrate.
• The plant cell wall is an elaborate extracellular matrix that encloses each cell in a plant.
• It was the thick cell walls of cork, visible in a primitive microscope, that in 1663 enabled Robert Hooke to distinguish and name cells for the first time.
• The walls of neighboring plant cells, cemented together to form the intact plant, are generally thicker, stronger, and, most important of all, more rigid than the extracellular matrix produced by animal cells.

 Animal Cell

• Desmosomes are one of the stronger cell-to-cell adhesion types and are found in tissue that experience intense mechanical stress, such as cardiac muscle tissue, bladder tissue, gastrointestinal mucosa, and epithelia.
• Animal cells simply have a cell membrane, but no cell wall.

 Bacterial cell walls

• Bacterial cell walls are made of peptidoglycan also called as murein, which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids.

Fungal cell

• The cell wall is a characteristic structure of fungi and is composed mainly of glucans, chitin and glycoproteins.

School mathematics has to be in close relation to the social worlds of children where they are engaged in mathematical activities as a part of daily life.

• Chemical change occurs when their is a change in the chemical properties of a matter.
  • When 2 or more reactants react they produce a compund having a different chemical composition.
• When iron rusts it reacts with the oxygen and water in the air to form it's hydroxide.
  • the brown coloured rust is the hydroxide of iron (Fe(OH)₃).
  • Reaction is -  4Fe + 3O₂ + 6H₂O → 4Fe(OH)₃

The expository Approach is also known as the Transmission Approach. In this approach, the teacher is communicating maximum information to the students in a minimum of time. This approach helps the teacher to
cover the content to be taught to the students. This approach is widely used across all subjects and different levels of education by the teacher. The main proponent of this method is David P. Ausubel.
In the expository approach all the cues provided by the teacher while teaching, the deductive thinking wherein abstract content is differentiated by the teacher giving appropriate examples to the students. The teaching Learning process is totally controlled by the teacher.
Note that:

• In Discovery Approach some cues in the form of learning material are presented by the teacher to the students and using Inductive thinking, the students are expected to discover the concept or the generalization/rule. Therefore the teaching-learning process is partially controlled by the teacher and students are also involved to a great extent. 
• In an Inquiry approach, the students are given a problem or a discrepant event. The students will ask the teacher questions to collect the data and they through interaction find out a satisfactory solution to a given problem or explanation of the given discrepant event. In this approach, the teaching-learning process is totally controlled by the students.

• Its specific resistance: A material with higher resistance will heat up more quickly, leading to faster melting of the fuse in case of overcurrent.
• Its radius: A thinner wire (smaller radius) will heat up and melt faster than a thicker one for the same material and current, making the fuse more sensitive.
• Its length: A longer wire has more resistance than a shorter one (for the same material and cross-sectional area), and therefore it will heat up more quickly.
• Current flowing through it: The fuse is designed to melt (or "blow") when a certain current threshold is exceeded. This is the fundamental operating principle of a fuse.
• However, if we had to choose the least important factor from the ones you listed, it would be the length of the fuse wire.
• In practical applications, fuse wires are usually very short, so while the length does technically affect the resistance (and therefore the heating), its effect is likely to be much smaller compared to the other factors.
• Still, this doesn't mean length is completely immaterial; it's just potentially less critical in most cases.
