Which is the best hypothesis for the scientific question "How does light intensity affect the rate of photosynthesis?" Light intensity, CO2 concentration, and temperature are factors that determine the rate of photosynthesis
Light intensity has no effect on the rate of photosynthesis.
If the distance between the source of light and the plant is increased, the rate of photosynthesis will decrease
O Light intensity has an impact on the rate of photosynthesis

i have to report this, it doesn't relate to biology

answer: wheres the options

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.

explanation:

on disadvantage of hydroelectric power is the cost. another disadvantage of using hydroelectric power is finding a water source powerful enough to harvest hydroelectric power.
