The gulf of california is located on the tropic of cancer. at what position of earth, will the sun be exactly overhead at the gulf of california? position 1 position 2 position 3 position 4

Option (D)

Explanation: Position D in the image represents the summer solstice. It is the condition when the sun is directly overhead the tropic of cancer (the gulf of California). It takes place on round 22nd of June every year, in which the norther hemisphere experiences summer solstice and the southern hemisphere experiences winter solstice.

The correct answer supporting the position is option (D).

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.
