Put these greenhouse effect events in order, starting with light's origin. Incident infrared radiation is blocked.
1 Visible and ultraviolet radiation heat Earth,
* Infrared radiation is blocked and heats Earth.
1 Earth radiates infrared radiation.

Earth radiates infrared radiation.

Incident infrared radiation is blocked.

Infrared radiation is blocked and heats Earth.

Visible and ultraviolet radiation heat Earth.

Explanation:

When the sunlight enters earth's atmosphere, it has short wavelength but after hitting the earth surface, it has long wavelength which allow very less solar radiation by the clouds and greenhouse gases to go into the atmosphere and as a result the earth heat up. if the greenhouse gases are increased in the atmosphere so more heat is blocked by these greenhouse gases and as a result global warming occur.

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.
