How do multicellular animals overcome limitations of diffusion? Choose the most complete answer they often have increased surface areas in key structures and mechanisms to move molecules in bulk they have structures that have increased surface areas for absorption they have systems to move molecules by bulk transport all of the cells are in direct contact with the environment so diffusion is easier
