Anatomy

1. The muscular tube that carries urine from the kidneys to the bladder is called the:

Correct answer: B

Rationale: The correct answer is B: Ureter. The ureter is the muscular tube that carries urine from the kidneys to the bladder. Nephrons are the functional units of the kidneys responsible for filtering blood. The urethra is the tube that carries urine from the bladder out of the body. The glomerulus is a cluster of blood vessels in the nephron that filters blood to form urine. Understanding the functions and locations of these structures is essential for comprehending the urinary system's overall process.

2. An object is thrown at an angle. Which of the following forces acts HORIZONTALLY on the object during its flight?

Correct answer: C

Rationale: Gravitational force acts downwards, normal force is perpendicular to motion at the launch point, and the throwing force is gone after release. Only air resistance acts continuously to oppose horizontal motion.

3. Where does fertilization, the fusion of sperm and egg, typically occur in the human body?

Correct answer: C

Rationale: The correct answer is C: Fallopian tube. Fertilization, the fusion of sperm and egg, typically occurs in the fallopian tube. After ovulation, the egg is released from the ovary and travels through the fallopian tube where it may encounter sperm for fertilization. The fertilized egg then moves to the uterus for implantation and development. The ovary releases the egg but fertilization occurs in the fallopian tube, making it the correct answer.

4. What happens to the potential energy of an object as it falls freely near the Earth's surface?

Correct answer: a

Rationale: As an object falls freely, its potential energy due to gravity decreases as it gets closer to the Earth's surface.

5. What is the function of the cell membrane?

Correct answer: A

Rationale: Rationale: The cell membrane, also known as the plasma membrane, serves as a protective barrier for the cell, separating the internal environment of the cell from the external environment. It is selectively permeable, meaning it controls the passage of substances in and out of the cell. This regulation of what enters and exits the cell is crucial for maintaining the cell's internal environment and ensuring proper functioning. Options B, C, and D are incorrect because storing energy, producing proteins, and synthesizing lipids are functions carried out by other cellular structures such as mitochondria, ribosomes, and endoplasmic reticulum, respectively, not the cell membrane.

6. A routine urinalysis is a common diagnostic test. What does a urinalysis typically evaluate?

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' A routine urinalysis is a comprehensive test that evaluates various aspects of urine to provide insights into overall health. Blood sugar levels can be assessed to screen for diabetes or monitor diabetes management. The presence of white blood cells in the urine can indicate a possible infection in the urinary tract. Additionally, kidney function can be evaluated by examining factors such as protein levels, creatinine, and electrolytes in the urine. Therefore, a urinalysis typically evaluates blood sugar levels, presence of white blood cells (indicating possible infection), and kidney function, making 'All of the above' the correct choice.
