There are many facilities which need to be provided for everyone. These are known as public facilities, for e.g. schools, healthcare, colleges, electricity, sanitation, public transport, safe drinking water, etc. The Constitution recognizes that the right to water is a part of the Right to Life under Article 21. So, it is the government’s duty to provide safe drinking water to every citizen.
An essential role is played by public services and facilities in providing support services to create sustainable, healthy, viable, and cohesive communities. So that they can overcome social barriers and can achieve something. Those facilities which are not possible for any individual to access at economic cost are mainly termed as facilities provided by the state. Hence, the government provides such facilities to the public to ensure the quality of life. There are many public facilities, the government provides in day-to-day life. The government has to ensure universal access to a public facility. The government has to provide a facility either without a charge or at a charge which is affordable to the masses. One important characteristic of a public facility is that once it is provided with its benefit can be shared by many people. For example; if a school comes up in a locality, many children are benefited from that school. Similarly, if a road is built through a village then many people are benefited from the road.

Amoeba takes in food using temporary finger-like extensions of the cell surface which fuse over the food particle forming a food-vacuole. Inside the food vacuole, complex substances are broken down into simpler ones which then diffuse into the cytoplasm. The remaining undigested material is moved to the surface of the cell and thrown out. The complete phagocytosis process includes intake, digestion , absorption, assimilation, and egestion process.

5. In a retail market, fruit vendors were selling mangoes kept in packing boxes. These boxes contained varying number mangoes. The following was the distribution of mangoes according to the number of boxes.
Find the mean number of mangoes kept in a packing box. Which method of finding the mean did you choose?
Ans. Since value of number of mangoes and number of boxes are large numerically. So we use step-deviation method.
From given data, Assume mean 
= 57, Width of the class 
= 3
= 
(approx.)
Using formula, Mean 
= 57 + 3 (0.0625) = 57 + 0.1875 = 57.1875 = 57.19 (approx.)
Hence mean number of mangoes kept in a packing box is 57.19.

Reflection |
Refraction |
|
This phenomenon usually occurs in mirrors. |
This phenomenon usually occurs in Lenses. |
|
Reflection can simply be defined as the reflection of light when it strikes the medium on a plane. |
Refraction can be defined as the process of shift of light when it passes through a medium leading to the bending of light. |
|
The light entering the medium returns back in the same direction. |
The light entering the medium travels from one medium to another. |
|
Considering the light waves, they bounce from the plane and change direction. |
The light waves pass through the surface while simultaneously change from medium to medium. |
|
The angle of incidence of the light is equal to the angle of reflection. |
The angle of incidence is not equal to the angle of reflection. |

The conservative regimes set up in 1815 were autocratic. They did not tolerate criticism and dissent, and sought to curb activities that questioned the legitimacy of autocratic governments.Most of them imposed censorship laws to control what was said in newspapers, books, plays and songs and reflected ideas of liberty and freedom associated with the French revolution.
