A student made the following table comparing the support structures in animals: Examples of Support Structures in Animals Exoskeleton Skeleton .The hard covering on the outside of invertebrates Helps support the body but prevents some movement The internal skeleton or backbone of vertebrates .Helps support the body and protects the internal organs. What statement best explains why the list is incorrect? Soft skin covers the exoskeleton in invertebrates. The exoskeleton helps support movement by working with the muscles. Invertebrates contain an internal skeleton or backbone. The skeleton protects and prevents movement in vertebrates.

18. determine whether each stateme blank space given. ach statement is true (t) or false (f). place your answer in the 8. when a cell is put into an isotonic solution, individual wat put into an isotonic solution, individual water molecules cannot move back and forth across the cell membrane. d. when a cell is put into a hypertonic solution, there is a net movement of water molecules across the cell membrane into the cell. c. when a cell is put into a hypotonic solution, there is a net movement of water molecules across the cell membrane out of the cell. d. the movement of any solvent across a semi-permeable membrane is called osmosis. e. carrier proteins have the ability to change shape and physically move molecules across the cell membrane. f. in facilitated diffusion, the concentration of the molecules to be moved across the cell membrane is higher inside the cell.
