Final answer:
The average human naturally sheds about 30,000 to 40,000 dead skin cells every minute from the stratum corneum, so the closest answer presented is b) 50,000 cells.
Step-by-step explanation:
The question of how many dead skin cells are shed every minute relates to the structure of skin and the process by which your body naturally replaces damaged or missing cells. The uppermost layer of the epidermis is called the stratum corneum, composed primarily of dead keratinocytes, which provides a waterproof barrier and protection to underlying layers. Over time, cells from the stratum corneum are shed from the body's surface.
Concerning the specific answer to the student's question, the average human sheds approximately 30,000 to 40,000 dead skin cells every minute. Since none of the options provided exactly match this range, it can be inferred that the closest correct answer from the options given is b) 50,000 cells.
