Because most leaves have two sides, do you think you have to double your calculation to obtain the surface area of one leaf? why or why not?

     Let's imagine that a leave is like a triangle, so, with this, how do we do the math to know the area? It's pretty simple right? A= l^2/4

      With that, if you imagine a leave as a triangle, what you need to know is its height by measuring it, and then do the math to find the result. You don't have to double ta calculation because you're already using the entire surface area by the height.

the correct answer is (

explanation:

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.
