ANSWER QUICK PLEASE BEING TIMED 7. a. Identify two inputs of the model in figure 4. b. Explain how figure 2 and figure 4 support a claim that a transformation of energy occurs during photosynthesis. Irina repeated her experiment, but changed her setup slightly. Before starting the experiment, she blew into the solution with a straw to add more carbon dioxide to the solution. c. Using figure 2 and figure 4, explain how additional carbon dioxide will change the outputs of Irina’s experiment.

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.
