Question

what is the primary purpose of organ systems in multicellular organisms? (1 point) process environmental signals perform specific body functions maintain structural integrity generate cellular energy

Explanation:

Organ systems in multicellular organisms are groups of organs that work together to perform specific functions for the body. For example, the digestive system processes food, the circulatory system transports substances. They are not mainly for processing environmental signals (that's more of the nervous - sensory system in part), maintaining structural integrity (though they contribute, it's not the main purpose), or generating cellular energy (that's mitochondria's role mainly).

Answer:

Perform specific body functions
