Which of the following statements correctly describe(s) the driving forces for diffusion of na+ and k+ ions through their respective channels? select all that apply. a. the diffusion of na+ ions into the cell is facilitated by the na+ concentration gradient across the plasma membrane. b. the diffusion of na+ ions into the cell is impeded by the electrical gradient across the plasma membrane. c. the diffusion of k+ ions out of the cell is impeded by the k+ concentration gradient across the plasma membrane. d. the diffusion of k+ ions out of the cell is impeded by the electrical gradient across the plasma membrane. e. the electrochemical gradient is larger for na+ than for k+.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;

genetic variation will increase because of a new habitat and food source.

explanation:

burning fossil fouls really decrease the carbon in the atmosphere so b
