Due to the short-term environmental change of a drought, much of the soil in an area can no longer support a species of wildflower. as a result, the plants now grow only in small regions within the area. which effect of an environmental change does this best illustrate? migration loss of habitat adaptation extinction

This change best illustrates the 3rd answer choice, Loss of Habitat.

The plants aren't migrating, but are rather only surviving in areas where there is enough moisture to support life. The wildflowers are not adapting to grow in dryer conditions, and the species is not going extinct, as there are still some areas where the plants can get enough moisture.

Hope this helped!

B. ) Loss of Habitat

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.
