u3t1: bone remodeling reading and questions

possible points: 4

bone remodeling serves several functions. it shapes the bones of the skeleton as a child grows, and it repairs tiny flaws in bone that result from everyday movements. remodeling also makes bones thicker at points where muscles place the most stress on them. in addition, remodeling helps regulate mineral homeostasis, because it either releases mineral from bones into the blood or absorbs mineral from the blood into bones. the figure below shows how osteoclasts in bones are involved in calcium regulation.

identify all reasons for bone remodeling.

maintain homeostasis
bone repair
digestive problems
stress from muscles
shape bones during growth

Explanation:

🆕 New Concept Discovered: Reading Comprehension & Evidence Extraction
Finding specific details directly stated in a text.

Step 1: Analyze the text for growth and repair functions

The text states: "It shapes the bones of the skeleton as a child grows, and it repairs tiny flaws in bone that result from everyday movements."

This directly matches two of the options:

• Shape bones during growth
• Bone repair

Step 2: Analyze the text for physical stress functions

The text states: "Remodeling also makes bones thicker at points where muscles place the most stress on them."

This directly matches the option:

• Stress from muscles

Step 3: Analyze the text for regulatory functions

The text states: "In addition, remodeling helps regulate mineral homeostasis, because it either releases mineral from bones into the blood or absorbs mineral from the blood into bones."

This directly matches the option:

• Maintain homeostasis

The text does not mention anything related to digestion or digestive problems.

Answer:

• Maintain homeostasis
• Bone repair
• Stress from muscles
• Shape bones during growth
