1. What is the muscular sac that stores urine until it is released from the body known as?

Correct answer: B

Rationale: The bladder is the muscular sac that stores urine until it is released from the body. It acts as a reservoir for urine until it is eliminated through the urethra. The urethra is the tube responsible for carrying urine from the bladder to the outside. The ureter transports urine from the kidneys to the bladder. The nephron is the structural and functional unit of the kidney involved in the filtration of blood and urine production. Therefore, the correct answer is the bladder, as it specifically fulfills the function of storing urine before its elimination.

2. Which of the following is a unit of work and energy?

Correct answer: B

Rationale: The correct answer is 'B: Kilowatt-hour (kWh).' The kilowatt-hour is a unit commonly used to measure electricity consumption, representing energy usage over time. A Pascal (Pa) is a unit of pressure, Coulomb (C) is a unit of electric charge, and Tesla (T) is a unit of magnetic flux density. Therefore, the kilowatt-hour is the appropriate unit for measuring work and energy in this context.

3. Which of the following is considered an extensive property?

Correct answer: A

Rationale: Weight is correctly identified as an extensive property. Extensive properties are dependent on the amount of the substance present. Weight is directly proportional to the quantity of the substance, making it an extensive property. In contrast, density, conductivity, and malleability are intensive properties, which remain constant regardless of the amount of substance. Therefore, the correct answer is 'Weight' as it changes with the quantity of the substance, aligning with the definition of an extensive property.

4. What is a contraceptive method that uses hormones to prevent ovulation?

Correct answer: C

Rationale: The correct answer is the Combined oral contraceptive pill (C). This method contains hormones (estrogen and progestin) that prevent ovulation, making it an effective contraceptive. Spermicide (A) is a substance that kills sperm and does not use hormones to prevent ovulation. Barrier methods (B) like condoms and diaphragms physically block sperm but do not involve hormone-induced prevention of ovulation. Intrauterine devices (IUDs) (D) prevent pregnancy through different mechanisms, such as altering the uterine environment and preventing sperm from fertilizing the egg, not by hormone-induced prevention of ovulation.

5. Dietary fiber, although not fully digested by the body, plays a crucial role in digestion. What is one of the main benefits of consuming sufficient dietary fiber?

Correct answer: C

Rationale: Consuming sufficient dietary fiber promotes satiety and gut health by adding bulk to the diet, helping with feelings of fullness, and supporting healthy digestion. Additionally, fiber aids in regulating bowel movements and maintaining a healthy gut microbiota, contributing to overall digestive wellness. It does not provide a concentrated source of energy as fiber is not fully digested for energy production, nor does it directly aid in the absorption of vitamins and minerals. Fiber does not break down complex carbohydrates but rather assists in their digestion and absorption by slowing down the process, which helps in maintaining stable blood sugar levels and promoting better overall health.
