physics

1. What property of a substance refers to its ability to undergo a chemical change and form new substances?

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo a chemical change or reaction, forming new substances with different properties.

2. What happens to the momentum of an object when there is no external force acting upon it?

Correct answer: c

Rationale: In the absence of external forces, momentum remains constant due to the conservation of momentum.

3. The term "goiter" refers to a condition characterized by:

Correct answer: B

Rationale: The term 'goiter' specifically refers to the abnormal enlargement of the thyroid gland. This can be due to various reasons such as iodine deficiency, Hashimoto's thyroiditis, or Graves' disease. Options A, C, and D are incorrect as they describe conditions related to other glands and hormones in the endocrine system. It is important to differentiate between different endocrine disorders to accurately diagnose and treat patients. Therefore, the correct answer is B, as a goiter is characterized by the excessive growth of the thyroid gland.

4. Urinary system health can be maintained through various lifestyle practices. Which of the following is NOT recommended for optimal urinary system health?

Correct answer: C

Rationale: The correct answer is C: Holding urine in the bladder for long periods. This is not recommended for optimal urinary system health because it can increase the risk of urinary tract infections and bladder problems. It is important to empty the bladder regularly to prevent bacteria from multiplying and causing infections. Limiting high-sodium foods in the diet helps maintain kidney health by reducing the risk of kidney stones and high blood pressure. Consuming cranberry juice can help prevent urinary tract infections due to its antibacterial properties. Regular moderate-intensity exercise promotes overall health, including good circulation to the kidneys and bladder.

5. Inhalation

Correct answer: B

Rationale: The correct answer is B: 'Respiration.' Inhalation refers to the process of breathing in air, while respiration is the overall process of gas exchange in the body, including both inhalation and exhalation. Expiration refers specifically to the process of breathing out air. Aspiration, on the other hand, refers to the act of inhaling foreign objects into the lungs, which can be harmful. Therefore, 'Respiration' is the most appropriate term related to 'Inhalation' as it encompasses the entire process of breathing and gas exchange in the body.

6. The structure surrounding and protecting the testes, maintaining optimal temperature for sperm production, is called the:

Correct answer: C

Rationale: The correct answer is C: Scrotum. The scrotum is the structure surrounding and protecting the testes. Its main function is to maintain the optimal temperature for sperm production by regulating the distance of the testes from the body to adjust to temperature changes. The epididymis (A) is a coiled tube where sperm mature, the vas deferens (B) is a duct that carries sperm from the testes to the urethra, and the prostate gland (D) is responsible for producing prostatic fluid that is a component of semen. Therefore, the scrotum plays a crucial role in protecting and regulating the temperature of the testes for proper sperm production.
