Question

which statement tells an advantage of multicellular organisms? one cell performs all of the necessary functions. all of the cells are the same. they can form complex organ systems. they can reproduce quickly.

Explanation:

Multicellular organisms have cells that differentiate and specialize. This allows them to form complex organ systems (e.g., circulatory, respiratory systems in humans) which perform specific functions more efficiently. In unicellular organisms, one cell does all functions (so the first option is a unicellular trait). Multicellular organisms have diverse cell types (not all same, ruling out the second option). Unicellular organisms often reproduce quickly (like bacteria via binary fission), so the fourth option is more for unicellular.

Answer:

They can form complex organ systems.
