In an experiment, a scientist makes a radioactively labeled probe using human dna. she then discovers that the probe hybridizes to a small segment of dna isolated from a plant. what can she conclude from her results? a. the plant might have a gene that is similar to a human gene. b. the wrong method was used to detect radioactively labeled dna. c. a plant cell has a cell wall, whereas a human cell does not. d. plant dna was accidentally used as a template to make the probe.

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.
