Q: Which of the following is the key difference between endocrine and exocrine glands?  

Answer: D

The main difference between endocrine and exocrine glands is that endocrine glands release hormones directly into the bloodstream, while exocrine glands release their secretions into ducts or at the surface of the body. Endocrine glands are ductless, and their secretions travel through the bloodstream to reach their target organs, where they help to regulate various bodily functions. Exocrine glands, on the other hand, have ducts that transport their secretions to specific locations within the body or outside the body, such as sweat glands, salivary glands, and mammary glands.
