Which is the best hypothesis for the scientific question "How does light intensity affect the rate of photosynthesis?" O Light intensity, CO2 concentration, and temperature are factors that determine the rate of photosynthesis.
O 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.
Light intensity has an impact on the rate of photosynthesis.

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.

the answer is:

carbon dioxide

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.

it would be heredity
