Shannon is making a Venn diagram to organize the characteristics of cell walls and cell membranes. Which pair of characteristics both belong in the two areas of the Venn diagram that do not intersect? helps with communication; contains mostly cellulose
contains mostly cellulose; forms the outer layer of animal cells
is found in plant cells; is found in animal cells
is semipermeable; found in animal cells

the answer is the second

Because cell wall made up of most cellulose while cell membrane the outer if the animal cell

B.

contains mostly cellulose; forms the outer layer of animal cells

Explanation: just took the test(❁´◡`❁)

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
