Answer the fоllоwing questiоns in the spаce below concerning the gаs exchаnge strategy and its relationship to the body plan of sponges and cnidarians.  Please label your answers as (a) and (b) -------------------------------------------- a) Sponges and cnidarians do not have specialized gas exchange structures. The body plan of these animals is constrained as a result. What property of diffusion is responsible for a constraint on the body plan of these animals?   b) The sponge and anemone  body wall consists of an outer layer of cells and an inner layer of cells.  Which of the following is true of the cells in the body walls of these animals? Write i, ii, iii, or iv in the space below. i) Each layer of cells in the body wall forms tissues that are better able to support the process of diffusion. ii) Each layer of cells in the body wall is several cells thick which increases the efficiency of diffusion. iii) Each layer of cells in the body wall are only one cell thick. iv) The number of cells in each of the layers of the body wall depends on the size of the sponge since size determines how much oxygen is needed.
