Question

11 multiple choice 1 point what function of the skeletal system is concerned with calcium and phosphorus ions important in muscle contraction and nerve impulse conduction? protection of internal organs support of the body mineral & fat storage 12 fill in the blank 1 point both choose your answer from choose your answer bones protect internal organs while choose your answer bones protect tendons 13 drag the attributes into the correct category. categ short sesamoid flat compact bone component(s)/attributes spongy bone component(s)/attributes no answers chosen

Explanation:

1. For question 11: The skeletal system stores minerals like calcium and phosphorus, which are critical for muscle contraction and nerve function; this is the role of mineral (and fat, via bone marrow) storage.
2. For question 12: Flat bones (e.g., skull, ribcage) protect internal organs, while sesamoid bones (e.g., patella) protect tendons.
3. For question 13: Compact bone is dense and forms the outer layer of bones, while spongy (cancellous) bone is porous and found inside bones; no attributes are pre-selected, so we assign the structural roles correctly.

Answer:

1. Question 11: Mineral & fat storage
2. Question 12:

• First blank: flat
• Second blank: sesamoid

1. Question 13:

• Compact Bone Component(s)/attributes: Dense outer bone layer, provides strength
• Spongy Bone Component(s)/attributes: Porous inner bone layer, houses marrow
