Question

select the correct answer. hormones are chemical molecules produced by glands. vasopressin is a hormone secreted by the cells of the hypothalamus, a part of the brain. the hormone regulates homeostasis through its effect on the kidney cells. which statement is true based on this information? a. all cells in the human body produce the same types of hormones. b. specialized cells allow for different organs to work together to perform a function. c. cells can work together only if they’re located in the same area of the body. d. all cells in the human body have the same structure and function.

Explanation:

• Option A: Different cells in the human body produce different hormones (e.g., thyroid cells produce thyroid hormones, pancreatic cells produce insulin), so A is false.
• Option B: Specialized cells form tissues, tissues form organs, and organs work together in organ systems. For example, hypothalamic cells (specialized) secrete vasopressin, and kidney cells respond to it, showing different organs (brain - hypothalamus, kidney) working together via specialized cells for homeostasis, so B is true.
• Option C: Cells can work together even if not in the same area (e.g., heart cells and liver cells are in different areas but part of the body's systems and interact indirectly), so C is false.
• Option D: Cells in the human body have different structures and functions (e.g., nerve cells vs muscle cells), so D is false.

Answer:

B. Specialized cells allow for different organs to work together to perform a function.
