Which type of tissue is in the image? (Figure 1)
- A. Compact bone
- B. Fibrocartilage
- C. Smooth muscle
- D. Simple squamous epithelial
Correct Answer: D
Rationale: Simple squamous epithelial tissue is the correct answer because it consists of a single layer of flat cells, which is characteristic of the tissue shown in Figure 1. This type of tissue is found in areas where rapid diffusion or filtration is required, such as the lining of blood vessels and the alveoli of the lungs. Its thin structure allows for efficient exchange of gases and nutrients.

Which of the following receptors does not span the cell membrane 7 times
- A. beta-Adrenergic receptor
- B. Rhodopsin
- C. 5-HTic receptor
- D. Mineralocorticoid receptor
Correct Answer: D
Rationale: The mineralocorticoid receptor is an intracellular receptor that does not span the cell membrane. It belongs to the steroid hormone receptor family and acts as a transcription factor after binding to its ligand. In contrast, beta-adrenergic receptors, rhodopsin, 5-HTic receptors, and LH receptors are G-protein-coupled receptors (GPCRs) that span the membrane seven times.
