Compare the amount of biodiversity in the United States to that of the rest of the world.

As the United States is a massive country the biodevirsity is also massive but around the world there are different biomes that would contain animals that USA simply doesn't because of its climate and environment. an example of this would be Antarctic or the middle East. a country with a large biodiversity is Brazil mainly due to its rainforests and sheer amount of different species residing in the Amazon rainforest

the rest of the world in the united states is bigger then some words and have much more people in it

Explanation: More than 200,000 native species have been identified in the United States, roughly 13 percent of the 1.5 million species worldwide currently recognized by taxonomists.

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.
