1. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?
- A. Wheezing
- B. Difficulty breathing
- C. Chest tightness
- D. Fever
Correct answer: D
Rationale: The correct answer is D: "Fever." Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing (A), difficulty breathing (B), and chest tightness (C). Wheezing is a high-pitched whistling sound that occurs during breathing, while difficulty breathing refers to the feeling of not getting enough air. Chest tightness is a common sensation of pressure or constriction in the chest. Fever is not a typical symptom of asthma but may occur in other respiratory conditions or infections. Therefore, fever is the correct answer as it does not align with the typical symptom profile of asthma.
2. Which hormone, produced by the pituitary gland, stimulates the production of milk in mammary glands during breastfeeding?
- A. Growth hormone (GH)
- B. Thyroid-stimulating hormone (TSH)
- C. Prolactin
- D. Follicle-stimulating hormone (FSH)
Correct answer: c
Rationale: The correct answer is C: Prolactin. Prolactin is the hormone produced by the pituitary gland that stimulates the production of milk in the mammary glands during breastfeeding. It plays a crucial role in lactation by promoting the growth and development of the mammary glands and initiating the production of milk. Growth hormone (GH) regulates growth and metabolism, not milk production. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland, not mammary glands. Follicle-stimulating hormone (FSH) is involved in reproductive processes, not milk production. Therefore, prolactin is the hormone directly responsible for stimulating milk production during breastfeeding.
3. Which of the following is NOT a characteristic of a chemical reaction?
- A. Formation of new substances
- B. Release or absorption of energy
- C. Change in color
- D. Change in temperature
Correct answer: C
Rationale: While color change can be an indicator of a chemical reaction, it's not always present, and some reactions occur without a visible color change.
4. Which of the following is a risk factor for developing kidney stones?
- A. Consuming a diet rich in fruits and vegetables
- B. Maintaining adequate hydration with water
- C. Having a family history of kidney stones
- D. Regularly engaging in moderate exercise
Correct answer: C
Rationale: Having a family history of kidney stones is a risk factor for developing them because genetics play a role in kidney stone formation. Individuals with a family history are more likely to inherit genetic factors that increase the likelihood of developing kidney stones. While consuming a diet rich in fruits and vegetables, maintaining adequate hydration with water, and regularly engaging in moderate exercise are generally healthy habits that can help prevent kidney stones, they are not direct risk factors for developing them. Therefore, option C, having a family history of kidney stones, is the correct answer.
5. How many moles of water are produced when 0.5 moles of methane (CH4) react with excess oxygen?
- A. 0.5 moles
- B. 1 mole
- C. 2 moles
- D. 3 moles
Correct answer: c
Rationale: The balanced equation is CH4 + 2O2 → CO2 + 2H2O, indicating a 1:2 ratio between CH4 and H2O.
6. Bile, a digestive juice, is produced by which organ?
- A. Stomach
- B. Liver
- C. Pancreas
- D. Small intestine
Correct answer: B
Rationale: The correct answer is B: Liver. Bile is a digestive juice that is produced by the liver and stored in the gallbladder. It plays a crucial role in the digestion and absorption of fats in the small intestine. The stomach primarily produces gastric juices that aid in breaking down food, while the pancreas secretes digestive enzymes and bicarbonate into the small intestine. The small intestine is responsible for the absorption of nutrients. Therefore, the liver is the organ that produces bile, making it the correct answer to this question.
