Question 2 of 5
Which type of tissue is characterized by cells found on the internal surface of the stomach, no extracellular matrix, tall and thin cells, and the absence of blood vessels?
Correct Answer: A
Rationale: The tissue described in the question, where cells are found on the internal surface of the stomach, are tall and thin, lack an extracellular matrix, and do not contain blood vessels, corresponds to epithelial tissue.

Question 4 of 5
Which of the following hormones decreases the concentration of blood glucose?
Correct Answer: A
Rationale: Insulin is the hormone responsible for decreasing the concentration of blood glucose levels by promoting the uptake and storage of glucose in cells. When blood glucose levels rise, insulin is released to help cells absorb excess glucose, thereby lowering its concentration in the bloodstream. Glucagon, growth hormone, and glucocorticoids, in contrast, all play roles in increasing blood glucose levels through different mechanisms.
