Question

complete each sentence by dragging the proper word or phrase into the appropriate blank. respiration movement support communication protection acid - base balance sensory reception minerals nutrient delivery the bones of the skeleton provide structure to the body and serve as a __________ to hold up the body and maintain proper positioning of some organs. the skull, pelvis, ribs, vertebral column, and sternum provide ________ to many delicate organs of the body by encasing them in hardened shell - like or caged structures. in the ________ of limbs and other skeletal elements, muscles span across joints to attach onto bones, which then serve as levers. the skeleton acts as a reservoir for the storage of __________ such as calcium, which is needed to support many cellular functions, including exocytosis and muscle contraction. marrow is contained within the hollow interiors of bones, and is responsible for

Explanation:

The first blank is about the function of bones providing structure and holding up the body, which is support. The second blank refers to the protective function of certain bones for delicate organs, so it's protection. The third blank is related to what muscles act upon in terms of limbs and skeletal elements for movement, which is movement. The fourth blank is about what the skeleton stores like calcium, which are minerals. Marrow in bones is responsible for hematopoiesis (production of blood - cells), but this option is not given, and the most relevant function among the options for marrow - related function is often considered in the context of its role in the body's physiological processes related to blood - cell production and storage which is not directly listed here but we can assume it's related to nutrient - delivery in a broad sense as it's connected to the body's overall physiological functions.

Answer:

1. support
2. protection
3. movement
4. minerals
5. nutrient delivery
