The correct Answer is:
To solve the question regarding the Arctic tern and its travel behavior, we can break down the reasoning into clear steps: ### Step-by-Step Solution: 1. **Understanding the Behavior of Arctic Terns:** - The Arctic tern is known for its long-distance migration, traveling from the Arctic region to the Antarctic region and back. This behavior is primarily driven by seasonal changes and the availability of food. 2. **Identifying the Concept of Migration:** - Migration refers to the seasonal movement of animals from one region to another. In the case of the Arctic tern, it migrates to take advantage of the summer months in both the Arctic and Antarctic, allowing it to experience two summers each year. 3. **Analyzing the Distance Traveled:** - The Arctic tern travels an average distance of 70,000 km annually. This significant distance is characteristic of migratory birds, which often travel vast distances to find suitable breeding and feeding grounds. 4. **Differentiating Migration from Other Concepts:** - The question provides options that include confirmation, regulation, suspension, and migration. - **Confirmation** refers to the ability of some birds to tolerate a wide range of environmental conditions, which does not apply to the Arctic tern. - **Regulation** involves birds that can only survive in specific climates, which is not the case for the Arctic tern. - **Suspension** describes a state of dormancy during unfavorable conditions, which is also not applicable here. - Therefore, the only suitable term that describes the Arctic tern's behavior is migration. 5. **Conclusion:** - Based on the analysis, we conclude that the Arctic tern's behavior of traveling between the Arctic and Antarctic regions is an example of migration. ### Final Answer: The Arctic tern's behavior is an example of **migration**. ---

A car travelling from south covers a distance of 8 kms, then turns right and runs another 9kms and again turns to the right and was stopped. Which direction does it face now?

There are two parallel streets each directed North to South. A person in the first street travelling from South to North wishes to take the second street which is on his right side. At some place, he makes a 150^(@) turn to the right and he travels for 15 minutes at the speed of 20 km/hr. After that he takes a left: turn of 60^(@) and travels for 20 minutes at the speed of 30 km/hr in order to meet the second street. What is the distance between the two streets?

A particle of mass m and charge q is accelerated by a potential difference V volt and made to enter a magnetic field region at an angle theta with the field. At the same moment, another particle of same mass and charge is projected in the direction of the field from the same point. Magnetic field induction is B. What would be the speed of second particle so that both particles meet again and again after regular interval of time. Also, find the time interval after which they meet and the distance travelled by the second particle during that interval.

Represent the following situations in the form of quadratic equations : (i) The area of a rectangular plot is 528 m^2 . The length of the plot (in metres) is one more than twice its breadth. We need to find the length and breadth of the plot. (ii) The product of two consecutive positive integers is 306. We need to find the integers. (iii) Rohan’s mother is 26 years older than him. The product of their ages (in years) 3 years from now will be 360. We would like to find Rohan’s present age. (iv) A train travels a distance of 480 km at a uniform speed. If the speed had been 8 km/h less, then it would have taken 3 hours more to cover the same distance. We need to find the speed of the train.

Hritik went straight eastward from his office and took a right turn after travelling 4 km. From here, he covered a distance of 3 km and again took a right turn. After covering a distance of 4 km, he finally turned left and travelled straight. In which direction was Hritik moving at the end?

A passage is given with five questions following it. Read the passage carefully and select the best answer to each question out of the given four alternatives. Antarctica is a mostly unpopulated continent. It is the coldest, driest and most remote place in the world. And it is the world's only continent that does not have a native population. No single country owns the Antarctic. However a number of countries, including Argentina, Australia, Chile, New Zealand, France and the United Kingdom, have already laid claim to the Antarctic and others will probably follow. In some areas of the continent, two countries claim the same land. The Antarctic Treaty was signed in 1959 and creates the rules for the exploration of the Antarctic. The treaty forbids military activity in the Antarctic, as well as mining. Many countries, however, think that there are valuable materials and minerals locked up under the frozen Antarctic ice. In addition, the treaty bans nuclear testing as well as dumping nuclear waste. The Antarctic Treaty was made to protect the continent and avoid further disputes. By 2048, the treaty must be renewed. New rules and regulations could be imposed by then. Currently, almost all of the 70 bases in the Antarctic are used for research and scientific activity. The snow-covered continent is perfect for tracking satellites and space research because it offers clear blue, cloudless skies. Climatologists are studying the development of the ozone layer with growing concern. It was here that a hole in the layer was discovered for the first time. More than 4000 scientists operate the research stations in the Antarctic summer, while only about a thousand populate the continent during the harsh and severe winters. Environmentalists fear that exploiting Antarctica for military and economic reasons will damage the environment. At present, there is no economic activity in Antarctica, except for cruise ships that travel around the continent. This could change, if a new treaty allows mining in the Antarctic. As mineral resources are dwindling in other areas, nations could turn to Antarctica to find and exploit valuable raw materials. Some geologists say that there are over 200 billion barrels of oil under the Antarctic ice. At the moment getting at these reserves would be very expensive. In addition, economic experts claim that there are large amounts of coal, nickel and copper under the Antarctic ice. According to the passage, the reserves of which mineral is not found under the Antarctic ice?
