Verified step by step guidance

Step 1: Begin by understanding the structure and function of the human skeleton. The skeleton provides support and protection for internal organs, serves as a site for blood cell production, and stores minerals such as calcium and phosphorus. These are all correct statements about the skeleton.

Step 2: Recall the number of bones in the adult human skeleton. While a newborn has approximately 270 bones, many of these fuse during development, resulting in an adult skeleton containing 206 bones. This is a key fact to identify the incorrect statement.

Step 3: Compare the given statements to the known facts about the skeleton. The statement 'The adult human skeleton contains over 300 bones' contradicts the established fact that adults have 206 bones.

Step 4: Conclude that the incorrect statement is 'The adult human skeleton contains over 300 bones,' as it does not align with anatomical knowledge.

Step 5: Review the other statements to ensure their accuracy. Confirm that the skeleton provides support and protection, serves as a site for blood cell production, and stores minerals like calcium and phosphorus, all of which are correct.
