Correct Answer: B
Rationale:
Question 2 of 5
What force primarily drives filtration in the kidneys?
Correct Answer: D
Rationale: Filtration in the kidneys is primarily driven by blood pressure. The glomerulus filters blood under pressure, allowing small molecules and fluids to pass through into the renal tubules while retaining larger molecules like proteins. Osmosis, smooth muscle contraction, and peristalsis do play roles in kidney function, but blood pressure is the main force responsible for the initial filtration process.

Question 4 of 5
A tissue examined under the microscope exhibits the following characteristics: cells found on the internal surface of the stomach, no extracellular matrix, cells are tall and thin, and no blood vessels are present in the tissue. What type of tissue is this?
Correct Answer: A
Rationale: The correct answer is A: Epithelial. Epithelial tissue is characterized by tightly packed cells that line the surfaces and cavities of organs. The description provided matches the characteristics of epithelial tissue, such as being found on internal surfaces like the stomach lining, having tall and thin cells, lacking an extracellular matrix, and not containing blood vessels. Connective tissue, muscle tissue, and cartilage do not match the described characteristics.
