pH is important in everyday life:

1. Existence of living beings

Organisms require a specific pH for their ideal growth and development. In the human body, all the physiological reactions take place in the pH of 7-7.8. The existence of aquatic plants, animals and microbes is at risk when acid rains mix with natural water bodies.

2. Digestion of food

The pH is important at different levels in the digestive system of the human body for the proper digestion of food. In the stomach, hydrochloric acid is secreted as food enters the stomach. It turns the pH of the stomach between 1 and 3. This pH is important for the activation of the enzyme pepsin, which helps in the digestion of protein in food.

3. Importance in soil

The pH of soil is a critical factor in the growth of crops and other plants. pH 6.5 to 7.3 is ideal for the growth of shrubs and crops. If the pH of soil is less than 6.5, lime is added to it to neutralise its acidity. Similarly, if the pH of soil is more than 7.3, gypsum is added to neutralise its basicity.

4. Stopping tooth decay

Teeth decay when the pH of the mouth falls below 5.5. Bacteria present in food and the mouth breakdown food particles left in the mouth and form acids. This results in lowering the pH of the mouth. Tooth powder and tooth paste which are used for cleaning of teeth are basic in nature. They neutralise the acid produced in the mouth and protect the teeth from decay.

5. Remedy for acidic effect of honeybee bite

When a honeybee bites, it inserts an acidic substance Melittin in our body. To get relief from it, an aqueous solution of a basic substance such as baking soda is applied around the place of bite. It helps to neutralise the acidic poison.

Lencho is the main character of the story “The Letter to God.” He is a poor farmer who is the sole bread-earner of the family. He had faith in God. Lencho lived in a small house which was situated on the crest of a low hill in the valley.  Throughout the morning Lencho sat in his house and waited for the rain to come. He wished for the rain or the shower for his field in which he had grown his crops.  Lencho wrote the letter to God as he thought that he would be the only one to help him in his bad times. He wrote a letter addressing to God to send him 100 pesos so that he and his family can survive in such a difficult situation.  

The postman in the story "A Letter to God" was of a very humble and kind in nature. When he saw that a person had written a letter addressing to the God he read the letter and decided to help the innocent person. He very well knew that there is no address of God to which he will deliver Lencho's letter. Hence he decided to not let Lencho's emotions down and help him by contributing money. But after seeing Lencho second letter everyone including the postman felt very sad as he had complained to God about the people working the post office.

Functions of Political Party:

1. Political Parties Contest Flections: Elections are fought mainly among the candidates put up by political parties.
2. Parties put forward different policies and programmes and the voters choose from them.
3. Parties Make Laws: Parties play a decisive role in making laws for a country. Laws are debated and passed in the Legislature.
4. Parties Form and Run Governments: The big policy decisions are taken by political executive that comes from political parties.
5. Role of Opposition: Those parties that lose in the elections play the role of opposition to the parties in power by voicing different views and criticising government for its faliures.
6. Parties Shape Public Opinions: They raise and highlight issues. Sometimes they launch movements for the resolution of problems faced by people.
7. Parties provide people access to government machinery and welfare schemes implemented by governments. For an ordinary citizen, it is very easy to approach a local party leader than a government officers.

Hydrochloric acid: It is the digestive fluid formed by the stomach during the process of digestion.

The Central government in India made a law for the Right to work in 200 districts of India is called National Rural Development Guarantee Act 2005 (NREGA, 2005). It is also known as Mahatma Gandhi National Rural Development Guarantee Act 2005 is an Indian labour law and social security measures that guarantees work. People who are able to and are in need of work are guaranteed 100 days of employment in a year by the government under this Act and the government give unemployment allowances to the people, if they fails to provide employment.

Answer:

g(x) = x² - x + 1

Step-by-step explanation:

On dividing x3-3x2+x+2 by a polynomial g(x),the quotient and remainder were x-2 and -2x+4 respectively.find g(x)

f(x) = x³ - 3x² + x + 2

q(x) = x - 2

let say

g(x) = ax² + bx + c

r = - 2x + 4

f(x)  = g(x)q(x) + r

=> x³ - 3x² + x + 2 = (ax² + bx + c)(x - 2) + (-2x + 4)

=> x³ - 3x² + x + 2 =  ax³ + x²(b - 2a) + x(c - 2b) -2c -2x + 4

=> x³ - 3x² + x + 2 =  ax³ + x²(b - 2a) + x(c - 2b - 2)  + (-2c  + 4)

Equating Power terms

a = 1

b - 2a = - 3  => b -2 = -3 => b = -1

c - 2b - 2 = 1 => c + 2 - 2 = 1  => c = 1

or -2c  + 4 = 2  => -2c = -2 => c = 1

g(x) = x² - x + 1

The  acronym for HTML is Hyper Text Markup Language. Initially, it was known by the name of GML (General Markup Language). In 1986, it was renamed to SGML (Standard Generalized Markup Language). In 1989, Sir Tim Berners-Lee and his team redesigned this language and named it Hyper Text Markup Language (HTML), as we know it today.
HTML is a markup language usually used to create the basic structure of a web-page. Using HTML with JavaScript (JS is a client-side programming language used to make HTML pages alive), we can even create Windows 10 Store Applications through Visual Studio.
Tags are a piece of code that tells the web-browser what to show and how to show. HTML is a tag-based language.

Two types of Tags.
Tags can broadly be classified into\

• Container Tags, and
• Empty Tags.

Container Tags are those tags which have both an opening and a closing tag.
Empty tags are those tags which have only an opening tag.

Some commonly used Tags.
Some common tags used in creating even the simplest of web-pages are listed below:

1. < html > .... < /html > - This tag is used in the beginning of each and every html document. This is a container tag and contains all the elements/tags of a html page.
2. < body > .... > - This tag contains the elements of a web-page that show up in the browser like text, images, forms etc...
3. < head > .... < /head > - This tag contains the elements of a web-page that don't show in the browser window such as style sheets, JS code, metadata, link to JS/CSS files, favicon.ico etc...
4. < h1 > < h6 > - Heading 1 to heading six are heading tags used in html. H1 is used for the largest heading. The font-size of the text in h1 to h6 tags reduces as we move from h1 to h6.
5. < p > .... < /p > - This tag is used for typing text in a website. It is generally used when we have to type a paragraph or more on a web-page.

Valli enjoyed watching the bus that travelled between her village and the nearest town through her street each hour. The sight of the bus, filled each time with a new set of passengers, was a source of unending joy for Valli. Her strongest desire was to travel up to the town and back to her village by the bus.

64 = 2 × 2 × 2 × 2 × 2 × 2

The given sequence is an A.P. with first term a=3 and common difference d=3. Let there be n terms in the given sequence. Then,

n^th term=111

a+(n−1)d=111

3+(n−1)×3=111

n=37

Thus, the given sequence contains 37 terms.

Ohm's law :- The potential difference across the ends of a resistor is directly proportional to the current through it, provided it's temperature remains the same.

The conditions for its validity is temperature and all other parameters should be constant.

The nature of the graph is a straight line passing through the origin.

Resistance is the physical quantity that can be determined from the graph.

Both the Prime Minister or the Chief Minister is members of the Parliament and the State assembly’s where rules and laws can be framed.

However, India Constitution has not given power to the Zila Parishad to frame laws & rules.

In the district, the state or central rules are implemented by the district magistrate though the Chairperson of the ZILA Parishad is head who is only a visionary of Planning & Development. Hence, the logic fails.

Land resources in India are primarily divided into agricultural land, forest land, land meant for pasture and grazing, and waste land. Waste land includes rocky, arid and desert areas, and land used for other non-agricultural purposes such as housing, roads and industry. According to the recent data, about 54% of the total land area is cultivable or fallow, 22.5% is covered by forests, and 3.45% is used for grazing. The rest is waste land, with traces of miscellaneous cultivation.
The land under forest has not increased since 1960–61 because in the post-independence era demand for more land to expand agriculture, mainly after Green Revolution, developmental works and infrastructural facilities, led to clearance of forests areas. Industrialization and urbanization also decreased the forest area. Thus, land under forest has increased by only about 4% since 1960-61.
