An action potential is a very rapid change in membrane potential that occurs when a nerve cell membrane is stimulated. Specifically, the membrane potential goes from the resting potential (typically -70 mV) to some positive value (typically about +30 mV) in a very short period of time (just a few milliseconds).eurons can respond to stimuli and conduct impulses because a membrane potential is established across the cell membrane. In other words, there is an unequal distribution of ions (charged atoms) on the two sides of a nerve cell membrane.
Aardvarks are small pig-like mammals that are found inhabiting a wide range of different habitats throughout Africa, south of the Sahara. They are mostly solitary and spend their days sleeping in underground burrows to protect them from the heat of the African sun, emerging in the cooler evening to search for food.
Predators are any animals that hunt and eat otheranimals ( prey ). There are some plants , such asthe Venus Fly Trap, that eat bugs. Humans are predators, and ourpets ar â¦ e. Sometimes we are the prey, such as with tigers, lions andcrocodiles. predators are psychologically very tiny animals. They are very dumb and people of the lesser world (humans) will think differently but our scientific research shows that predators are idiots a lion hyena a lepoard and algae in the morning
