Tamara lives in the united states. she has been hospitalized several times due to severe respiratory allergies. ozone affects her condition the most. she enjoys spending time outdoors but is very careful when she steps outside. in which scenario will it be best for tamara to do her outdoor activities? a.) noon in juneb.) 1 pm in octoberc.) 5 pm in juned.) 1 pm in july

B. 1pm in October

Lowest ozone levels ever recorded are in early October and in the pm (noon to 6 pm) air pollutions is at its lowest levels.

The correct answer is B

Explanation:

A) Considering conditions of noon in June US, the summer months experiences the stratosphere layers to become vulnerable due to erosion exposing the livestock, crops to ozone and harmful radiation.

B) 1 pm in October is period when winter sets in so the heat is reduced much wherein the stratosphere is not vulnerable to erosion.

C) 5pm in June is again summer month when the sun's inclination is reduced. But as it is summer, the heat is still prevalent.

D) 1p in July is part of summer period.

From above, we can observe that the best period when Tamara would not be affected by ozone is 1pm in October.

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.
