General Science Test Trivia: Quiz!

Explanation
Louis Pasteur is credited with the discovery and development of pasteurization. He was a French chemist and microbiologist who made significant contributions to the field of microbiology. Pasteurization is a process of heating liquids to kill bacteria and other microorganisms, thus preventing spoilage and extending the shelf life of food and beverages. Pasteur's work revolutionized the food and beverage industry, making it safer and more hygienic. His discoveries and techniques in microbiology have had a profound impact on medicine, agriculture, and public health.

Explanation
Food remains safe below 5 degrees Celsius because at this temperature, the growth of bacteria and other microorganisms that can cause foodborne illnesses is significantly slowed down. Refrigerating food at or below this temperature helps to preserve its quality and prevent the growth of harmful pathogens. It is important to store perishable foods, such as meat, dairy products, and cooked leftovers, in the refrigerator to ensure their safety and reduce the risk of food poisoning.

Explanation
The types of wastage mentioned in the question are water, natural, man-made, qualitative, and quantitative. However, the correct answer is qualitative and quantitative. This suggests that the question is asking specifically about the types of wastage that can be categorized as qualitative or quantitative. The other options mentioned may also be types of wastage, but they do not fall under the qualitative or quantitative categories.

Explanation
World Food Day is observed on 16 October. This day is celebrated to raise awareness about hunger and promote worldwide action to ensure food security for everyone. It aims to highlight the importance of access to nutritious and sustainable food for all people around the world.

Explanation
If akshata is not used during wedding feasts, it means that there will be no wastage of food. Akshata is a Hindu ritual where rice is offered to deities and then distributed to the guests as a blessing. By not using akshata, it implies that the rice will not be offered or distributed, thus eliminating any potential wastage of food.

Explanation
Fruit-eaters animals are herbivores because they primarily consume fruits as their main source of food. Herbivores are animals that have adapted to eat plant material, such as leaves, stems, and fruits. Fruits are a rich source of nutrients and energy for herbivores, providing them with essential vitamins, minerals, and carbohydrates. By consuming fruits, herbivores play an important role in seed dispersal, as they help in spreading the seeds of plants to new areas. Therefore, herbivores are the correct classification for animals that primarily eat fruits.

Explanation
The density of normal water is 1gm/cc. Density is a measure of how much mass is contained within a given volume. In the case of water, 1 gram of water occupies 1 cubic centimeter of space. This means that water is relatively dense compared to other substances, as it has a mass of 1 gram for every cubic centimeter of volume.

Explanation
A solute is a substance that dissolves in a solvent to form a solution. In this case, the solute refers to the substance that dissolves in water.

Explanation
The substance that dissolves in a solution is called the solute. The solute is the component that is being dissolved in the solvent to form a homogeneous mixture, known as a solution. The solvent is the substance that is doing the dissolving, allowing the solute particles to separate and disperse evenly throughout the solution. Therefore, the solute is the substance being dissolved, while the solvent is the substance doing the dissolving.

Explanation
When a solute dissolves in a solvent, it forms a solution. A solution is a homogeneous mixture of two or more substances, where the solute is evenly distributed and dispersed throughout the solvent. The solute particles separate and disperse in the solvent particles, resulting in a uniform mixture. Therefore, the correct answer is "solution."

Explanation
The molecular formula C6H22O6 represents glucose, a type of sugar that is commonly found in food. Glucose is an important source of energy for the body and is a component of carbohydrates. It is often referred to as a "simple sugar" and is found in various foods such as fruits, vegetables, and grains. The molecular formula indicates the number and type of atoms present in a molecule, in this case, 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.

Explanation
The correct answer is 6.5-7.5. This range indicates that the pH of normal soil is slightly acidic to slightly alkaline. Soil pH is an important factor that affects the availability of nutrients to plants. Most plants prefer a slightly acidic to neutral pH range for optimal growth. Therefore, a pH range of 6.5-7.5 is considered normal for soil.
