There are different people with different opinions and each of their opinion makes sense as each of them have valued points that can explain the reason for their opinion.
If I say yes, that WhatsApp, Instagram Facebook, Snapchat are killing the creativity level of a person and the reason behind that the people who can be more creative in the real life are spending more time watching the videos, chatting and clicking pictures, etc and they are always on their phone showing off their lifestyles to the world . Social media is more important for them than the real world, how many likes they got on the picture, what are the comments, how many views got, number of followers and competition, comparison these are all the things that a person experience on social media. But they can spend there day being creative in there life.
If I say that, no WhatsApp, Facebook Instagram and Snapchat all things are in fact helping the artistic and talented people to present their talent and finding the people who respect their talent is also true because we can see online, that there are so many dance video and singing video painting videos, showing their makeup art and their drawing, sketches, etc. They are able to connect to their old friends and they are gaining love, respect and attention that they deserve for their talent, that they don’t get in real life or they are just getting the spotlight from the social media platforms
Both of opinions are correct depending on person to person. It depends what they are doing on the social media. Is that productive or they are just using social media to relax and explore, it is also important that the excessive use of anything is harmful and not utilising your resources is also not good. So you should balance out everything in your life.

The phenomenon behind twinkling of stars is known as ‘atmospheric refraction’.
When the light from the stars enters the atmosphere of earth, the light from stars undergoes the refraction due to the different density of atmospheric gases (air) on different levels before coming to us. So the refractive index change continuously and refract the light coming from the stars in different amount. In this way, the starlight reaching our eyes increase and decrease due to the uneven density of atmospheric air present in its paths. That’s why they appear to twinkle.
Planets do not twinkle because they are larger in size and very close to us in compared to stars which are far away from us and large in size. So as we know there are many other planets in our solar system. So planets can be taken as a collection of large number of point sized sources of light. As they are in group, so the starlight that comes from them to our eyes as an individual which basically gives that twinkling effect will be average out of zero, which nullify the twinkling effect of each other.

First of all why we should we avoid food wastage?
Not only you yourself should avoid food wastage but also make sure that around you, no one is wasting food. Daily millions of people had to starve themselves and their family. Many die due to appetite, malnutritions. Just because they don’t have money to buy food. These includes beggars, farmers, peasants, etc like people who have seasonal or no work at all. Many just get food once a day, same because they cant afford it or nobody had given the left over from there house. At last when they don’t want to die due to starvation they eat from trash bin, eating literally anything they get. Then they get sick and eventually they die from different diseases, as they don’t have money to go to hospital and seek proper treatment. There are many animals on street, you can feed them as all animals cannot fight for there food as they are weak due to less age or malnutrition. But most importantly they also need care. this is a very simple, kind and should be done act of humanity by all to all who needs it, whether animals or humans.
How we can avoid wastage of food?
1) Whatever is left over food is there in your house. Go outside and give them to animals on street and maybe some poor people, beggar, etc but don’t throw it away or leave it in your house to stale.
2) You can make a commercial spot somewhere in your neighbourhood where everyone can donate their food who need it.
3) Spread awareness about it.
4) make sure you don’t leave food in your plate or cook extra, or buy extra food which you cannot finish by yourself. If this happens you can donate it also.
5) Keep things which can stay fresh for a long time or store them properly. There are many ways to do these things.
6) If you are really passionate about these things, you can join NGO or organisations, etc.

Autotrophs are the only producers in ecosystem, which provide foods to all the other levels in the ecosystem. They produce their own food and not only for themselves, but for the decomposers and consumers as well. In the consumers also there are three categories, those are herbivorous, carnivorous and omnivorous and for all these categories the food base is produced by the autotrophs.
Example- The plant is the producer (autotrophs) and the plant is consumed by the deer that is the (harbivour) and then the deer is consumed by the lion that is a (carnivore) and then the lion is consumed by the (decomposer) those are bacterias and worms, etc.
Now how to use autotrophs create their own food? Basically all the green plants comes under this categories and as we know they produce their own food by the process of photosynthesis. In this process autotrophs take in substances from the outside and convert them into stored forms of energy. This material is taken in the form of carbon dioxide and water which is converted into carbohydrates in the presence of sunlight and chlorophyll. Carbohydrates are utilised for providing energy to the plants the carbohydrate within not used immediately are stored in the form of start with search as the internal energy reserve to be used as and when required by the plants.

Division of French society was the social cause of French Revolution. This was an Ancient regime. French Society was divided into three major sections.
1st Estate- These includes Clergy (church), Bishops, Pops, Fathers, Mothers, Sisters, ( Priest). Overall all the important people of society. Rich families, Part or officials of bourbon dynasty. They never have to pay taxes. There population was around 1 lakhs. land owned by them was 10% of whole France. The area each family of 1st estate used to hold was large, but they were not much in number in compared to 2nd, 3rd class. They had powers because they were part of the religion, rich businessman, officials who support and help in promoting the harsh bourbon rule.
2nd Estate- These were all the land owners, notabilities, ( Shaukar), etc. There population was 4 lakhs. They owned 25% of land n the whole France. They also never pay taxes. They were the local rich men, They didn’t hold so much power, but still they were considered powerful because they used to give work to the poor farmer, and slavery and they were rich and they hold land. As the 3rd estate never had land on which they can work and they were large in number so the 2nd estate people used to provide work to 3rd estate.
3rd Estate- These includes farmers, artist, Factory workers, traders, lawyers, public officials. Some of them are educated but still poor. there population was 2.7 crore, 95% of the total population. But all of them don’t even have properties. They used to pay all the taxes, harsh rules and regulation were applied on them. They didn’t hold any power or importance in France during that time.
The educated class known as Bangeoisies they used to work for king.

The twinkling of stars happens because of atmospheric refraction of the light coming from the stars as a individual. When the starlight enters the earths atmospheres, it has to pass through so many layers/densities of air at various levels and different altitude and so it refract a lot before reaching to our eyes. The continuously changing atmosphere refract the star light in different amount at different range. So in this way, the starlight reaching our eyes increases and decreases continuously and so the stars appear to twinkle. Scattering of light is traveling of light from one medium to another and this happens in the whole process when starlight comes to our eyes from the star. As it has to go through different densities, atmospheric conditions, and altitudes.

Gandhi ji and congress launched the famous Quit India movement in August 1942. This was the 3rd mass movement against British. A resolution was passed on 8 August 1942 Bombay (Mumbai) by the All Indian Congress Committee demanding end of the British rule. Mass struggle were organised all over the country.
All Indians were politically charged. Even women and children were inspired and they participated enthusiastically. All were inspired by Gandhi ji’s slogan ‘ DO OR DIE ‘ ( Karo yah maro ) was a great source of inspiration. On 9 August 1942, the British arrested Gandhi ji and other senior leaders and declared the congress the illegal organisation. The people reacted violently to this, as the news of their leaders arrest shocked the entire country. In this anger many Indians destroyed police stations, post offices, railway lines, etc.
The British government used extensive force to crush the movement. Thousands of people were sent to jails. Thousands were killed, peaceful processions were lathi-charged. The British imprisoned most of the leaders of the Congress. During this time a terrible famine occurred in Bengal ( 1943 ). Over 30 lakhs people died. The government did little to alleviate the suffering of these people.

Oxygen is one of the most important gases. A living organism is alive only if they are getting proper amount of oxygen and it doesn’t matter if it’s a animal or human or aquatic animal. Humans and animals that lives on land acquired oxygen in the form of gas and the aquatic animals require oxygen from water that is present in the form of H2O.
Oxygen is important because it helps a body to create energy for daily activities. Like walking, talking even for sleeping we require energy and that energy is made when oxygen is in our body. Oxygen helps in breaking down of of complex substances that we intake as food into the simplest substance to convert them into carbohydrates glucose and starch that is obtained by a body in order to provide energy to us to do daily task.
If oxygen disappeared is from the planet it will not only affect living organisms, but also their surroundings and the things present in the atmosphere because many elements like buildings, concrete walls are bond together because they have oxygen present in their building blocks and if oxygen disappear concrete building will fall down within a minute. It will affect water as well as water consists of Oxygen and hydrogen and if oxygen disappeared from water it will be just hydrogen left. There will be change in climate as well as the atmospheric conditions. Many Cycles will be disturbed completely because there will be no oxygen.
Of course oxygen is very important for maintaining life on earth. Being human and other living organisms are made this way that new require oxygen to stay alive.

First of all what is a prism? a prism is a transparent refractive medium, which has two triangular bases and three rectangular plane surfaces. The transparent beam of light is made up of seven colours these are VIBGYOR ( V=violent, I=indigo, B=Blue, G=green, Y=yellow, O=orange, R=red ). As we know that these are the colours present in a rainbow as well. When we passes a transparent beam of light through the prism that is a transparent refractive medium, which splits that single beam of light into the seven colours this phenomenon is called dispersion of light. The process of obtaining band of seven colours obtained from the beam of light is called the spectrum of light.
Isaac Newton was the first one to use a glass prism to obtain the spectrum of light.
Now we can see that the spectrum that is formed through the prism it gives a figure of the rainbow. But actually a rainbow is a natural spectrum that is appeared in the sky after the rain shower. It is formed when dispersion of sunlight happens through the tiny water droplets that act as a transparent refractive medium present in the atmosphere. The sunlight refract and disperse the incident sunlight, then reflect it internally and finally, refracted again when it comes out of the raindrop which finally gives us the seven different colours which results in a actual rainbow. Spectrum of light obtained through the prism is a lab experiment to show the spectrum of light and phenomenon of dispersion.

What does respire means? Respire is the exchange of gases to break down the food material into the simplest form to produce energy from it, to work in daily life. The the food material that is taken in during the process of Nutrition is used in cell to provide energy for various life processes. Diverse organisms use different ways, some use oxygen and some do not and some use other pathways to breakdown those food particles into glucose, into pyruvate to provide energy for the life processes. In all the cases the first step is breakdown of glucose this process takes place in cytoplasm.
There are two type of respiration anaerobic and aerobic respiration.
Aerobic respiration= Breakdown of pyruvate using oxygen takes place in the mitochondria which gives energy the body to work.
Anaerobic respiration= Pyruvate may be converted into ethanol and carbon dioxide. This process take place in yeast during fermentation since this process is done in the absence of oxygen.
We can see that in this both respiration some kind of gas is used or involved in it, which produce components, which provide energy to the body to work. That’s why it is important to respire for a living organism to live.

Our 2/3 earth is covered with water but only 1% water is suitable for consumption. Besides that 1% of water rest has very high amount of salt present in it, which is very harmful for living organism to consume.
Day by day our rivers are draining out which once used to provide fresh water to us. Rivers not only provide water for daily use to people living near it but also a high number of farmers use river water to irrigate their fields. the groundwater level is getting reduced rapidly as the usage is high, but the water is unable to reach down within earth crust as plastic had already made a layer on the ground surface, which does not allow rain water or any from any other form of water to go down. Factories that produce chemical waste release these harmful waste materials without even filtering them directly into water bodies. At the same time they use water for there production also. the sewage system is also not designed well as the dirty water released from our homes produced by our daily activities is also sent to water bodies without even getting filtered.
Soon there will be no fresh water left for our use. If this continue to happen in future we have to invest a huge amount of money in placing filters for using water. so its better to save water from now. there are any people who didn’t even get water to drink. to meet their daily water requirement they had wait for hours or for days. In some different parts of world people have to walk miles to have water for a day.
Save water for future from today.

Malleability- The ability of beating some selective metals into thin sheets. this property is called malleability.
Gold and silver are most malleable metals.
Ductility- The ability of metals to be drawn into thin wires is called ductility. Gold is the most ductile metal.
You know, that a wire of about 2 km length can be drawn from 1 gram of gold.
It is because of their Malleability and ductility that metals can be given different shapes according to our needs. We can also see that, in our household there are many different things made of metal, all in different shapes and size. Examples- cooking utensils, wire for electricity supply in whole house, chains, almiras, racks, showpecies, etc.

Exothermic reactions- When we observe that from any reaction a high amount of heat is evolved. This makes the reaction mixture warm. Reaction in which heat is released along with the formation of products are called exothermic reactions.
Example- Burning of natural gas, respiration, decomposition of vegetable matter into compost.
Endothermic reactions- If we observe that while performing any reaction if any form of energy is absorbed or required either as heat, light or electricity for breaking or making the reactants. So reactions in which any form of energy is absorbed are known as endothermic reactions.

We apply paint on objects made of iron not only to make them look attractive, but also to prevent them from rusting.
Now what is rusting? When iron is exposed to moist for a long time it acquires a coating of brown hard layer on it called rust. Which is developed because iron easily react with water and air which results in rusting of any object made of iron. This whole process of rusting of iron is called corrosion. It happens not only on iron but on many other objects which form a hard layer on object but of different colour. There is a condition that iron will only rust when it is in contact with water and air for long time without any protection layer on it.
The rusting of Iron can be prevented by painting, oiling, greasing, etc. These things create a protection layer on iron, which prevent iron to come in contact with air and water.
Example- We all have seen iron nails in our household which are used to hang things. When they are new they appear silver or have shiny luster on them. But after 2 or 3 months if you notice the same nail it will appear to have a brown hard layer coating on it. That is rust.
On the other hand if you see the cycle that we all had as kids or have. Some part of it is made of iron which is painted and if paint is removed we can clearly see the iron. We also take our cycles for oiling monthly so that the chains in cycle won’t get stuck or stop working, start creating weird crackle noise if they are not oiled or greased monthly.

There are 100 of species of birds which live in different habitat and they are of different size. Now the common thing in all these birds is, they all lay eggs. Like they migrate or go from one place to another but there eggs cant do the same. So basically before laying eggs these birds make sure that they have a comfy and cosy palace to lay there eggs. They also make sure that the place should be matching there required habitat and its safe. In that perfect place for there eggs they make their nest where they can lay there eggs. After they lay there eggs in that nest they protect those eggs. Till the eggs are not broke and a baby bird came out of it they give their body warmth to the eggs. Once the baby birds comes out of the eggs, they still live in that same nest for few months, so that the mother can teach her children how to fly, eat, catch food, etc skills for living. Once they are big enough to live on their own they all fly away.
It takes time to build a nest. As birds needs to pick many stings, feather and other comfy stings for them to weave those things together and make a comfy nest of them.
Now as we already know birds are of different sizes, so of course the size of there eggs will depend on the size of their parents.
Example- An ostrich egg weight around 1600 – 2500 gram. They can lay 60 eggs at a time. So just imagine the size of the nest of an ostrich, its really big.
Where a humming birds eggs weight is around 2.5 gram. So they only need a small nest.
