    • True

    • False

    Correct Answer

    Explanation
    Tomatoes are classified as fruit because they develop from the ovary of a flower and contain seeds. Although commonly thought of as a vegetable due to their culinary uses, scientifically, they meet the criteria to be considered a fruit. Fruits are the mature ovaries of flowering plants that contain seeds, and tomatoes fit this definition. Therefore, the correct answer is true.

    Babies have around 300 bones at birth, while adults have around 206 bones. As babies grow, some of their bones fuse together, resulting in a decrease in the total number of bones. Therefore, it is true that babies have around 100 more bones than adults.

These essential vitamins include vitamin A, vitamin C, vitamin D, vitamin E, vitamin K, and the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B6, vitamin B12, and folate).

    Unsaturated fats are usually ----------  at room temperature.

    • Liquid

    • Solid

    Correct Answer
    A. Liquid
    Explanation
    Unsaturated fats are usually liquid at room temperature because they have double bonds in their carbon chains. These double bonds introduce kinks in the structure of the fat molecules, preventing them from packing tightly together. As a result, unsaturated fats have a lower melting point and remain in a liquid state at room temperature. In contrast, saturated fats lack double bonds and have a straighter structure, allowing them to pack tightly and solidify at room temperature.

    Which nutrient gives more energy when compared to carbohydrates?

    • Vitamins

    • Fat

    • Proteins

    • Option 4

    Correct Answer
    A. Fat
    Explanation
    Fat is the nutrient that gives more energy when compared to carbohydrates. While carbohydrates provide 4 calories per gram, fats provide 9 calories per gram. This is because fats are more concentrated in energy and require more metabolic processes to be broken down and utilized by the body. Therefore, consuming foods high in fat can provide a greater amount of energy compared to foods high in carbohydrates.

    Dietary fibre is also known as

    • Carbohydrates

    • Minerals

    • Roughage

    • Option 4

    Correct Answer
    A. Roughage
    Explanation
    Dietary fiber is commonly referred to as roughage because it consists of plant-based substances that cannot be fully digested by the human body. It adds bulk to the diet, aids in digestion, and helps prevent constipation. Roughage is an important component of a healthy diet as it promotes regular bowel movements and contributes to overall gut health.

    Water - soluble vitamin

    • Vitamin D

    • Vitamin A

    • Vitamin E

    • Vitamin B

    Correct Answer
    A. Vitamin B
    Explanation
    Vitamin B is the correct answer because it is a water-soluble vitamin. Water-soluble vitamins are easily dissolved in water and are not stored in the body, so they need to be consumed regularly through the diet. Vitamin D, Vitamin A, and Vitamin E are all fat-soluble vitamins, meaning they are absorbed and stored in fat cells in the body.
