SOCIETY as a whole, needs several things which the private sector will not be able to provide at a reasonable cost.
Following are the reasons for this:

1. Activities in the private sectors are guided by the motive to earn profit and not welfare of the people.
2. There are several services needed by the society which the private sector cannot provide at a reasonable price. Activities like construction of roads, bridges, railways, irrigation through dams etc, require huge amount of money which is beyond the capacity of the private sector. Private sector charges high amount for the use of these services.
3. It is difficult for the private sector to collect money from thousands of people who use these services.
4. The private sector sometimes ignore regional balanced development equality of income and development of basic industries.
5. Private sector includes profit margins whereas, the government will charge a reasonable price for services. It is the primary duty of the Government to ensure the provision of public facilities with a service motto.

The terms “national awakening” and “national revival” refer to a historical process that has occurred in many parts of the world, and that marks nationalism's emergence as a potent political force in some particular country or region. The Estonian Age of Awakening is a period in history where Estonians came to acknowledge themselves as a nation deserving the right to govern themselves. This period is considered to begin in the 1850s with greater rights being granted to commoners and to end with the declaration of the Republic of Estonia in 1918.

Here we are basically analyzing Series and Parallel Circuits.
Let us first understand some characteristics.
★ Series Circuit
→ Current through each resistor is same.
→ Voltage Drop is different across each resistor.
★ Parallel Circuit
→ Current is different through each resistor.
→ Voltage Drop is the same across each resistor.
Coming to the question: Three bulbs are connected, once in a Series Circuit, and once in a Parallel Circuit.
Let us assume that the battery is of Voltage V.
(i) In Series Circuit, the voltage drops across the bulbs. Each bulb has a voltage drop of (V/3) across it.
Each bulb glows with the same brightness.
In Parallel Circuit, each bulb receives a Voltage V.
Again, each bulb glows with the same brightness.
However, the bulbs in Parallel Circuit glow with more brightness as compared to bulbs in Series Circuit.
The reason is simply that Parallel Circuit Bulbs receive more Voltage.
(ii) One bulb is fused.
In Series Circuit, if one bulb is fused, all other bulbs will stop working. Because the current cannot flow to the other bulbs
However, in Parallel Circuit, there are still other pathways for current to flow.
The fused bulb will stop working, but the other bulbs will continue to glow with the same brightness.
(iii) The diagram is attached.
 

Human Digestive System

A human digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. The food we take in is digested and utilized by our body and the unused parts of the food are defecated. Human digestive system is the sum of the gastrointestinal tract (GIT; also called alimentary canal) and accessory organs (tongue, liver, pancreas, etc). These two parts together help in digestion in humans.

The alimentary canal is the long tube through which the food that we eat is passed. It begins at the mouth (buccal or oral cavity), passes through the pharynx, esophagus or food pipe, stomach, small intestines, large intestines, rectum and finally ends at the ****. The food particles get digested gradually as they travel through various compartments of the alimentary canal. Accessory organs are organs which participate in the digestion process but are not actually a part of GIT. They stimulate the digestion by releasing certain enzymes.

Food begins its journey through the digestive system in the mouth, also known as the buccal cavity or the oral cavity. The mouth has many accessory organs such as the tongue, teeth, and salivary glands, which help in the digestion of food. Teeth grind the food into small pieces. Salivary glands secrete saliva which contains an enzyme called the salivary amylase. This enzyme breaks down starch content and moistens the food, before the tongue and other muscles push the food into the pharynx.

 Pharynx: The pharynx passes the chewed food from the mouth to the esophagus. The flap of tissue known as the epiglottis present in pharynx prevents food from entering into the wide pipe

Esophagus or Food Pipe: The esophagus is a muscular tube connecting the pharynx to the stomach. It carries swallowed masses of chewed food along its length and pushes it down to the stomach.

 Stomach: The stomach is a thick-walled muscular bag that is located on the left side of the abdominal cavity. It is the largest part of the human digestive system. Stomach acts as a storage tank for food so that the body has time to digest large meals properly. It receives food from the food pipe at one end and opens into the small intestine at the other end. The inner walls of the stomach consist of the gastric glands which secrete mucous, hydrochloric acid and digestive enzymes. These continue the digestion of food that began in the mouth.

Mucous protects the lining of the stomach while acid kills bacteria that enter the body along with the food. Hydrochloric acid also makes the medium in the stomach acidic, which helps the digestive enzymes like pepsin to act. The digestive enzymes break down proteins into simpler substances.

Small Intestine: The small intestine is the longest part of the human digestive system. It is a highly coiled long, thin tube which is about 7.5 metres in length. The length of the small intestine depends on the diet of the organism. A major proportion of digestion takes place in the small intestines. All types of nutrients are digested here with the help of secretions which it receives from the liver and the pancreas. The walls of the small intestine also secrete juices for digesting food.

The liver releases bile juice which alkalizes the acidic food received from the stomach and also emulsifies the fat content. The pancreatic juice digests the proteins and lipids. Finally, the intestinal secretions convert the carbohydrates into glucose, proteins to amino acids and fats into fatty acids and glycerol.

Once the food is broken down into the simple particles, it is ready to be absorbed by the body. The villi, finger-like projections present on the walls of the small intestine, absorb the digested food by increasing the surface area. The absorbed food is then transported to different parts of the body through the blood vessels for cell activities.

Large Intestine: The large intestine is a long, thick tube which is about 1.5 meters long. The large intestine absorbs water and small amounts of nutrients from the undigested food with the help of many symbiotic bacteria residing in it. The remaining waste passes into the rectum, where it remains as semi-solid feces. Feces exit the body through the **** via time-to-time excretion. This process is called Digestion.

The importance of pipeline:

(i)Pipeline transport network is a new arrival on the transportation map of India. In the past, these were used to transport water to cities and industries.

(ii)Now, these are used for transporting crude oil, petroleum products and natural gas from oil and natural gas fields to refineries, fertilizer factories and big thermal power plants.

(iii)Solids can also be transported through a pipeline when converted into slurry.

(iv)The far inland locations of refineries like Barauni, Mathura, Panipat and gas based fertilizer plants could be thought of only because of pipelines.

(v)Initial cost of laying pipelines is high but subsequent running costs are minimal. It rules out trans-shipment losses or delays.

Its main function is the packaging and secretion of proteins. It receives proteins from Endoplasmic Reticulum. It packages it into membrane-bound vesicles, which are then transported to various destinations, such as lysosomes, plasma membrane or secretion. They also take part in the transport of lipids and the formation of lysosomes.

Post-translational modification and enzymatic processing occur near the membrane surface in Golgi bodies, e.g. phosphorylation, glycosylation, etc.

Golgi apparatus is the site for the synthesis of various glycolipids, sphingomyelin, etc.

In the plant cells, complex polysaccharides of the cell wall are synthesised in the Golgi apparatus.

Lewis structures (also known as Lewis dot structures or electron dot structures) are diagrams that represent the valence electrons of atoms within a molecule. These Lewis symbols and Lewis structures help visualize the valence electrons of atoms and molecules, whether they exist as lone pairs or within bonds. The outermost central level of energy-containing electrons is called the level of valence and includes electrons of valence. Lewis symbols are diagrams showing the number of valence electrons of a specific element with dots indicating lone pairs.

The marriage of my friends brother came off in Nov. I was cordially invited to attend that. It weans the grandest marriage, I had ever attended. It afforded great joy and mirth to every member of the procession. It is an unforgettable experience.  

On the day of marriage, the house of my friend was tastefully decorated with multi colored flowers, bunting and balloons. A served with juice, sweets, dry fruits and coffee. In the evening at about 4 p.m., some ceremonies, prior to the departure of the Barat were performed. Everybody was putting on his best suit. There was joy and cheer everywhere.  

The priest put a coronet decked with flowers on the bridegroom’s head. The women started singing songs. The bride groom was made to ride a mare decked with ornaments’ of silver. The best band of the city created sweet sensations by its tunes of modern films. The Barat started on foot towards the bride’s house. It was at a distance of half a mile. The party of jolly young boys and girls began to dance and twist to the tunes of the band. There was a drum beater surrounded by lust young bachelors chancing and jumping at the head of the barat, crackers were also let off. ‘The father of the bridegroom was throwing handfuls of paisa which attracted many a child. The on lookers were looking at the Barat with eager eyes from both the sides of the roads. Ina word the Barat presented a gala sight to all.

The Barat reached near the bride’s house. Its decoration beggared description. Multi colored bulbs, flowers and buntings decorated the house and it looked as if it were a place in paradise. The seating arrangement was made under a very big canopy. The Barat received the heartiest reception.  

The priest recited verses from the scriptures. The bride’s father and bride groom’s father embraced each other amidst shouts. The automatic camera took photographs. The bride groom was made to ride a mare decked with ornaments of silver. The best band of the city created sweet sensations by its tunes of modern films. The Barat started on foot towards the bride’s house. It was at a distance of half a mile.

The dowry was arranged in a big room. It included everything meant for a house and a television set, refrigerator and a car for the bridegroom. The marriage was solemnized amidst Vedic mantra’s before the holy fire. In the early dawn the bride parted from her parents with tears in her eyes to start a new life in her in laws house.

The non-metal X is carbon.The hardest natural substance y is diamond and Z which is a good conductor of electricity is graphite.

Ohm’s law states the relationship between electric current and potential difference. The current that flows through most conductors is directly proportional to the voltage applied to it. Georg Simon Ohm, a German physicist was the first to verify Ohm’s law experimentally.

One of the most basic and important laws of electric circuits is Ohm’s law. Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature remain constant.

The poem written by Leslie Norris explains the agony and helplessness of a caged tiger that lives in a zoo. The poet explains what his life could be if he had been a free animal.

All road safety measures using the prevention of road accidents and road safety defend. While traveling on the road, it is to save people. These are all people who use the street as a pedestrian for safe, two-wheel, four-wheel, multi-wheeler and other vehicles used for abusers. Of all people throughout their entire lives to follow road safety measures is very good and safe. All the time while driving or walking should respect others and must care for their safety.

Plain road, avoid injury and death is one of the very important aspects of road safety. Complete information about accidents and deaths on national statistical data, we can evaluate the importance of road safety. Approximately 42% of the pedestrians who use and are one-way street

Many ways to create awareness among the general public, such as seminars, workshops, courses, students in basic road safety education by adding text, wait, see, listen, think and then cross the Green Cross Code of the People made aware, learn the traffic lights, road signs, etc. Understanding. To avoid problems following the road all road safety measures help a lot. Some of the most effective road safety measures, such as basic information about the vehicle, according to weather and road conditions, defensive driving, vehicle using lights and horn, seat Belt wear, correct use of the vehicle windshield, to avoid over-speed, roadway lights understanding, keep distance from other vehicles on the road, proper handling of trouble understanding, awareness documentary broadcast on TV and more..

No it is not possible to have a party-less democracy because political parties are necessary to conduct elections and to make parliamentary system more systematic

A government formed by the coming together of at least two political parties is called coalition government.

Following are the effects of biomagnification on living organisms and the environment:

Impact on Human Health

Biomagnification makes humans more prone to cancer, kidney problems, liver failure, birth defects, respiratory disorders, and heart diseases.

Effects on Reproduction and Development of Marine Creatures

The toxic chemicals accumulate in the important organs of aquatic organisms that affect their reproduction and development processes.

For eg., the shells of the eggs of the sea-birds are very thin that might get crushed by the birds themselves during incubation. The toxic chemicals, mercury and selenium destroy the reproductive organs of aquatic creatures.

Destruction of Coral Reefs

Cyanide that is used in leaching gold and fishing is the main cause of the destruction of coral reefs. Coral reefs are the dwelling and feeding grounds for many sea creatures. Their destruction affects the lives of many aquatic animals.

Disruption of Food Chain

The chemicals and toxins which are released into the water bodies disrupt the food chain. The small organisms absorb the toxins which are eaten up by larger animals. These toxins, thus, get accumulated in the higher level of organisms.
