A Trivia Science Quiz

Wood is the most suitable material for building a chair because it is strong, durable, and can withstand the weight and pressure exerted on it. Wood is also easily available, versatile, and can be shaped and carved into various designs. Additionally, wood has a natural aesthetic appeal and can be finished with different stains or paints to enhance its appearance. Overall, wood provides the necessary strength, stability, and aesthetic qualities required for building a chair.

A metal spoon is magnetic because it is made of a ferromagnetic material, such as iron or steel, which contains magnetic properties. These materials have unpaired electrons that align themselves in a way that creates a magnetic field. This allows the metal spoon to be attracted to magnets and exhibit magnetic properties. On the other hand, a wooden spoon and socks do not contain ferromagnetic materials, so they are not magnetic.

Eating too many sugary foods can cause tooth decay because the bacteria in our mouth feed on the sugars from the food we eat and produce acids. These acids can erode the enamel, which is the protective layer of our teeth, leading to cavities and tooth decay. Brushing your teeth twice a day and visiting the dentist are actually good practices to maintain oral hygiene and prevent tooth decay. Therefore, the correct answer is eating too many sugary foods.

A balanced diet and exercise are essential for maintaining good health. A balanced diet provides the body with all the necessary nutrients it needs to function properly, while exercise helps to strengthen muscles, improve cardiovascular health, and maintain a healthy weight. Both components work together to support overall physical and mental well-being.

The correct answer is the mattress for beds. Mattresses typically have springs inside them to provide support and comfort while sleeping. Springs help to distribute weight evenly and reduce pressure points, resulting in a more comfortable sleeping surface.

An herbivore is an animal that primarily consumes plants as its main source of food. They do not eat meat, making option B, "A plant eater," the correct answer. Herbivores have specialized digestive systems that allow them to break down and extract nutrients from plant material. They play an important role in the ecosystem by helping to control plant populations and serving as a food source for carnivores.

A carnivore is an organism that primarily consumes meat as its main source of nutrition. It does not eat plants or have a diet that includes both meat and plants. Therefore, the correct answer is "A meat eater."

A bat is a flying animal because it has wings that allow it to fly. Unlike elephants, lions, and cats, bats have the ability to soar through the air using their wings. They are nocturnal creatures that are known for their unique flying abilities and echolocation.

Humans have two sets of teeth during their lifetime. The first set, known as primary or baby teeth, starts to erupt around 6 months of age and is eventually replaced by permanent teeth. The second set, known as permanent teeth, begins to come in around 6 years of age and consists of 32 teeth, including 8 incisors, 4 canines, 8 premolars, and 12 molars.

Canines, molars, and incisors are all types of teeth. Canines are the pointed teeth located on either side of the front teeth, used for tearing and gripping food. Molars are the flat teeth at the back of the mouth, responsible for grinding and chewing food. Incisors are the sharp, thin teeth at the front of the mouth, used for cutting and biting food. Dentist, on the other hand, is not a type of tooth but a profession related to dental care and treatment.
