Potential difference is nothing but voltage and is measured by a device called Voltmeter. It is always connected in parallel across the points whose potential difference is to be measured.
- SI unit of electric potential difference is Volt (V).
- SI unit of Work done is Joule (J).
1 V = 1 J/ 1 C, potential difference is 1 when 1 joule work is done to move 1 coulomb of charge from one point to another

Conservatism was a political philosophy that stressed the importance of the tradition and preferred gradual development to quick change.
Features of the believers of conservatism:
- They believed in established, traditional institutions of state and policy.
- They believed in a monarchy, the Church, social hierarchies, etc.
- They did not propose to return to the society of pre-revolutionary days, rather they realised that modernisation could, in fact, strengthen the traditional institutions like the monarchy.

The use of land is determined by
i) Physical factors such as topography, climate, soil types
ii) Human factors such as population density, technological capability, culture and traditions.
Few unsatisfactory features of our land use pattern:
i) The land under permanent pasture has decreased.
ii) Forest area of the country is far lower than the desired 33% of the geographical area, as it was outlined in the National Forest Policy (1952).
III) Some human activities such as deforestation, overgrazing, mining and quarrying have contributed to the degradation of about 130 million hectares of land in India.

The denudation of the soil cover and subsequent washing down leads to serious problems as it leads to soil erosion It is in fact the serious problem as it washes away the top layers of the soil causing erosion and degradation of l and
There are many factors that can be associated with soil erosion :
a. Natural factors- Lack of vegetation cover, excessive rainfall, topography, wind direction
b. Human causes- Excessive use of fertilisers, pesticides. Over grazing, deforestation Over irrigation increases the salt deposits in the soil Mining-leaves deep scars and traces of over-burdening Dumping of industrial effluents It effects the overall land under cultivation and in turn production. Excessive practise of shifting cultivation

Amoeba is a holozoic and protozoan. The digestion is intracellular as it is a unicellular organism. The food taken remains in a food vacuole or gastric vacuole formed by the cell membrane and a bit of the cytoplasm. The vacuoles are transported deeper into the cells by cytoplasmic movements. Here they fuse with lysosomes that contain enzymes such as amylase and proteinase. Thus, amoeba can digest sugar, cellulose and protein. Fats, however, remain undigested.
Nutrition in Amoeba:-
Food - Amoeba is a holozoic and omnivorous animal. It feeds upon microscopic organisms like bacteria, Paramecium, Diatoms, Algae and dead organic matter.
Nutrition in Amoeba involves the following steps:
(i) Ingestion:- Amoeba has no mouth so ingestion may occur at any point of body surface but generally it occurs at the advancing end of the body. Ingestion occurs with the help of pseudopodia. The opening of food cup gradually becomes narrower and narrower, and finally closes. So the food is finally enveloped and taken inside a food-vacuole (called phagosome) along with a drop of water.
(ii) Digestion:- Amoeba shows intracellular and vacuolar digestion. In the cytoplasm, food vacuole fuses with lysosomes containing digestive enzymes. In this, the complex and non-diffusible nutrients are changed into simple and diffusible nutrients. Medium inside the food vacuole is first acidic but later becomes alkaline, (as in the alimentary canal of man).
(iii) Absorption:_ In absorption, the diffusible nutrients pass through the vacuolar membrane into the cytoplasm by diffusion and are then distributed to all the body parts by streaming movements of cytoplasm called cyclosis. Due to this, the size of food vacuole gradually decreases.
(iv)Assimilation: In the cytoplasm, a part of the absorbed food is oxidised to produce energy, most of the simple nutrients are combined to synthesise complex compounds. Thus, the absorbed food materials are utilised to get energy through respiration and make the different parts of Amoeba cell and it leads to the growth of Amoeba.
(v) Egestion: Egestion may occur at any point on the body surface.

The colonial powers exploited the colonies. This led to the emergence of anti-colonial movements in Asian and African countries. The anti-colonial movement was nationalist in character because people who fought against the imperial powers were inspired by a sense of collective national unity. They began to consider their country not just as a region inhabited by people of various identities but as a single unified nation.

The growth of modern nationalism is intimately connected to the anti-colonialmovement in India, just like in any other country.
In the process of their struggle with colonialism people began discovering their unity.
Anti-colonial movement gave a strong issue to the people with which they could identify and could come on a common platform.
All though each class or group of people felt that they were being oppressed under colonialism, the effects of colonialism were felt differently.
Hence, the growth of nationalism in the colonies is linked to an anti-colonial movement.

Potential Difference = Work done / Charge
V = W / Q
GIVEN
Potential Difference = 6V
Work Done = Energy = W
Charge Q = 1C
∴ Potential Difference = Work done / Charge
V = W / Q
6V = W / 1
6*1 = W
Work = Energy = 6 J

The mechanism of urine formation takes place in following steps-
(i) Ultrafiltration- All the blood components are filtered by the kidneys except for the blood cells and the plasma proteins, e.g. urea, water, sodium, glucose, potassium,etc.
(ii) Selective reabsorption- The essential components are reabsorbed back into the blood vessels, e.g. glucose, water, sodium, etc.
(iii) Secretion- The movement of elements such as water, glucose, amino acids, urea etc from the blood into the nephron is known as secretion. For example, potassium ions and hydrogen ions are secreted by distal
convoluted tubule (DCT) and uric acid and other toxic chemicals secreted by proximal convoluted tubule (PCT)
iv) Then the water reabsorption content is further regulated before coming out of the kidney through a hormone, anti-diuretic hormone (ADH).
(v) Urine is then formed, collected in the bladder and excreted outside the body.

x2 - 21x+ 108
= x2 - 12x - 9x + 108
= x(x - 12) - 9(x - 12)
= (x - 12)( x -9)
