Potassium has the greatest influence on the resting membrane potential. Resting membrane potential is caused by the differences in the concentrations of ions inside and outside the cell. At resting membrane potential there are more sodium ions outside the neuron and more potassium ions inside the neuron. For a neuron the resting membrane potential is about -70 mV.
Answer:
Potatoes grew in the mountainous regiosn of Bolivia and Peru because they prefers such climates. Climates that are on the cold side but not so cold that the ground would be frosty. A temperature of between 60° to 70°F is considered ideal and anything above 80° F is considered too warm for them even though they have been known to adapt.
The soil should be very mildly acidic with a pH of between 5.0 to 5.5. Potatoes prefer to be grown in the full presence of the sun in well drained soils that are not compact or constantly wet.
The Environmental conditions are therefore;
- Cold but not too cold
- Well drained soil
- Mildly acidic soil.
- Abundance of sunlight.
