Aclient is being treated for the ingestion of a neurotoxin that interferes with the depolarization phase of action potentials.
what physiologic process will be disrupted?

The inflow of sodium ions.

Explanation:

The generation of the action potential requires the change in the membrane potential of the cell. This membrane potential is maintained due to the unequal distribution of the ions.

The cell potential of the cell is -70mV and maintained due to the presence of potassium ions. The depolarization occurs due to the influx of the sodium ions and results in the change in the membrane potential upto +30mV. The neurotoxin that interferes with depolarization process might affect the sodium ions uptake.

Thus, the answer is inflow of sodium ions.

straight fertilizers

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
