The correct Answer is:
To determine how many of the given statements about the human reproductive system are incorrect, we will analyze each statement one by one. ### Step 1: Analyze Statement A **Statement A:** The uterus is an inverted pear-shaped organ. - The uterus is indeed known as an inverted pear-shaped muscular organ. This statement is correct. ### Step 2: Analyze Statement B **Statement B:** Each testis possesses 150 testicular tubules. - This statement is incorrect. Each testis actually possesses approximately 250 testicular lobules (also referred to as seminiferous tubules). Therefore, this statement is incorrect. ### Step 3: Analyze Statement C **Statement C:** Mammary tubules open into the mammary ducts. - This statement is correct. The mammary glands consist of lobules that contain mammary tubules, which indeed open into the mammary ducts. Thus, this statement is correct. ### Conclusion Now, we summarize our findings: - Statement A: Correct - Statement B: Incorrect - Statement C: Correct Thus, out of the three statements, only **one statement (Statement B)** is incorrect. ### Final Answer **Only one statement is incorrect.** ---
