A very tall building is called a skyscraper because it is a term used to describe a high-rise building that has multiple floors and is significantly taller than the surrounding buildings. Skyscrapers are often found in urban areas and are known for their impressive height and architectural design. They are constructed using strong materials and advanced engineering techniques to ensure stability and safety at such great heights. Skyscrapers have become iconic structures in many cities around the world, symbolizing progress, modernity, and urbanization.Rate this question:

Doctors give people a ____________ to prevent disease like polio.
- A.
Skyscraper
- B.
Vaccine
- C.
Pasteurization
Correct Answer
B. VaccineExplanation
Doctors give people a vaccine to prevent diseases like polio. A vaccine is a biological preparation that contains a weakened or killed form of a specific pathogen, such as a virus or bacteria. When administered, it stimulates the immune system to produce an immune response, including the production of antibodies, without causing the actual disease. This helps the body recognize and fight the pathogen if it is encountered in the future, providing immunity and preventing the disease from occurring.Rate this question:

Making something free of germs by using heat is known as ____________________.
- A.
Vaccine
- B.
Pasteurization
- C.
Skyscraper
Correct Answer
B. PasteurizationExplanation
Pasteurization is the process of heating a substance, such as milk or juice, to a specific temperature for a certain amount of time in order to kill or deactivate harmful microorganisms, including bacteria and viruses. This process helps to make the substance free of germs and safe for consumption. Vaccines, on the other hand, are substances that stimulate the immune system to protect against specific diseases, while skyscrapers are tall buildings. Therefore, the correct answer for making something free of germs by using heat is pasteurization.Rate this question:
