Question

how scientists explain this: the muscular system cant move the arm without help from the skeletal system. as the force animations demonstrate, the nervous system activates the proper number of muscle bundles and learns how much force is needed to lift objects of different weights. the blood flow animations show that the circulatory system brings blood, oxygen, and sugar to the muscles so that they can function. the respiratory system delivers oxygen to the blood. your conclusions: the circulatory, respiratory, and nervous systems. what do you think? how does your conclusion compare to how scientists explain this?

Explanation:

The conclusion correctly identifies the circulatory, respiratory, and nervous systems as important for arm - movement as per the scientific explanation. The scientific explanation elaborates on the specific functions each system plays. The nervous system controls muscle activation, the circulatory system supplies nutrients to muscles, and the respiratory system provides oxygen for the blood. The conclusion aligns with these key points.

Answer:

The conclusion is consistent with the scientific explanation as it mentions the relevant systems and their general importance in arm - movement, though the scientific explanation provides more detailed functions of each system.
