1. What is the medical term for an ingrown hair?

• A. Folliculitis
• B. Hirsutism
• C. Pseudofolliculitis Barbae
• D. Alopecia

Correct answer: A

Rationale: The correct answer is A, Folliculitis. Folliculitis is the medical term for the inflammation of hair follicles, which can be caused by ingrown hairs. Hirsutism refers to excessive hair growth, pseudofolliculitis barbae is a condition where shaving causes ingrown hairs, and alopecia is hair loss. Therefore, choices B, C, and D are incorrect as they do not specifically refer to ingrown hairs.

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

• A. Limiting high-sodium foods in the diet
• B. Consuming adequate amounts of cranberry juice
• C. Holding urine in the bladder for long periods
• D. Getting regular moderate-intensity exercise

Correct answer: C

Rationale: Holding urine in the bladder for long periods is not recommended for optimal urinary system health. It can increase the risk of urinary tract infections and other bladder-related issues. When urine is held for a long time, bacteria have more time to multiply in the bladder, leading to infections. Additionally, holding urine for prolonged periods can also contribute to bladder distension, which may affect bladder function over time. Therefore, it is crucial to empty the bladder regularly to maintain good urinary system health. Limiting high-sodium foods helps reduce the risk of kidney stones and high blood pressure, while consuming cranberry juice may help prevent urinary tract infections by interfering with the adhesion of bacteria to the bladder walls. Regular moderate-intensity exercise promotes overall health, including maintaining a healthy weight and reducing the risk of chronic conditions that can impact the urinary system.

3. An object is initially at rest. Which of the following will definitely NOT cause it to move?

• A. A constant force acting on it
• B. No force acting on it
• C. A force that increases in magnitude over time
• D. A force that decreases in magnitude over time

Correct answer: B

Rationale: The correct answer is B because if an object is initially at rest and no force is acting on it, it will remain at rest due to Newton's First Law of Motion. This law states that an object at rest will stay at rest unless acted upon by an external force. Choices A, C, and D all involve forces acting on the object, which would cause it to move according to Newton's laws of motion. Choice A, a constant force acting on the object, would cause it to move at a constant velocity. Choice C, a force that increases in magnitude over time, would accelerate the object. Choice D, a force that decreases in magnitude over time, would decelerate the object.

4. What is the name for the process by which a cell divides into two daughter cells?

• A. Meiosis
• B. Mitosis
• C. Fission
• D. Binary fission

Correct answer: B

Rationale: Mitosis is the correct process by which a cell divides into two genetically identical daughter cells. Meiosis involves two rounds of cell division resulting in four daughter cells with half the number of chromosomes as the parent cell. Fission refers to the division of a single-celled organism into two separate organisms, while binary fission specifically describes the division of prokaryotic cells. Therefore, the correct answer is Mitosis as it accurately represents the process of a cell dividing into two daughter cells.

5. Which part of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs, which is then pumped into the left ventricle and out to the rest of the body. The right atrium receives deoxygenated blood from the body and sends it to the right ventricle to be pumped to the lungs for oxygenation. Choices B, C, and D are incorrect as they do not directly receive oxygenated blood from the lungs.
