2. Which hormone is responsible for the characteristic changes experienced during puberty, such as breast development and menstruation in females?

• A. Follicle-stimulating hormone (FSH)
• B. Luteinizing hormone (LH)
• C. Estrogen
• D. Progesterone

Correct answer: C

Rationale: The correct answer is C: Estrogen. Estrogen plays a crucial role in regulating the development of secondary sexual characteristics during puberty in females. It is responsible for breast development, widening of hips, and the onset of menstruation. Estrogen is mainly produced by the ovaries and is essential for the maturation of the reproductive system. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are pituitary hormones that regulate the menstrual cycle and ovulation but do not directly cause the characteristic changes seen during puberty. Progesterone is another hormone involved in the menstrual cycle and pregnancy but is not primarily responsible for the physical changes during puberty.

3. A medication dosage is listed as 1/4 gram. What is the equivalent dosage in milligrams (1 gram = 1000 milligrams)?

• A. 125mg
• B. 250mg
• C. 375mg
• D. 500mg

Correct answer: D

Rationale: Multiply the gram dosage (1/4) by the conversion factor (1000mg/gram) to get 250 milligrams.

4. Which of the following organs is responsible for churning and mechanically breaking down food?

• A. Small intestine
• B. Large intestine
• C. Stomach
• D. Esophagus

Correct answer: C

Rationale: Rationale: The stomach is responsible for churning and mechanically breaking down food. It contains muscles that contract and relax to mix food with digestive juices, breaking it down into smaller particles. This mechanical digestion process helps prepare the food for further digestion and absorption in the small intestine. The small intestine is primarily responsible for the absorption of nutrients, the large intestine absorbs water and salts, the esophagus is a muscular tube that transports food from the mouth to the stomach.

6. Which respiratory structure is responsible for the humidification and warming of inhaled air?

• A. Trachea
• B. Larynx
• C. Nasal passages
• D. Bronchi

Correct answer: c

Rationale: The correct answer is C: Nasal passages. The nasal passages are lined with mucous membranes that produce mucus to humidify and warm the inhaled air before it reaches the lungs. This process helps to protect the delicate lung tissues from drying out and becoming irritated. The trachea, larynx, and bronchi play important roles in the respiratory system, but specifically, the nasal passages are primarily responsible for humidifying and warming the air as it enters the body.
