When the membrane is at the potassium equilibrium potential, in which direction (in or out) is there a net movement of potassium

ions?

  • The balance between the chemical and electrical forces pushing potassium through potassium channels and across the membrane is represented by the potassium equilibrium potential.
  • At the equilibrium potential of potassium, which is -80mV, there is no net movement of potassium ions.

<h3>At potassium's equilibrium potential, what happens?</h3>
  • At equilibrium, the electrical potential gradient across the membrane precisely balances the gradient of K+ concentration.
  • There is no net migration of K+ from one side to the other, despite the fact that K+ ions continue to traverse the membrane via channels.

<h3>How does potassium diffuse in order to influence the membrane potential?</h3>
  • Potassium ions will flow down their concentration gradient, or towards the exterior of the cell, because the membrane is permeable to them.
  • Although the membrane is not permeable to sodium, there is a concentration gradient that favors sodium diffusion in the opposite direction.

Give an example of a direct and indirect interaction between two organisms
horsena [70]

Answer:

The example of direct interaction between two organisms is in coral reefs some fishes behave as a cleaner for the other fish.

Explanation:

The fish eats the parasites which harms the other fish. In this the cleaner fish gets food and the other fish gets rid of parasites. The example of indirect interaction between two organisms is when the birds eat the caterpillar, there is a positive impact on the plants because the Caterpillars used to the leaf of the plants.

The direct interaction between two organisms is defined as when the action of one organism has a direct impact on the other organism. The indirect interaction between two organisms is defined as when the action of one organism is responsible for indirect impact on the other organism.

Based on this information what is the likely relationship between common garter snakes and rough-skinned newts
SVEN [57.7K]

The relationship between the garter snakes and rough-skinned newts is their evolutionary race.

Grater snakes are resistant to the TTX (the toxin of the rough-skinned newts).

TTX-resistant snakes (resistance was formed via mutation) cause natural selection to favor ever-more poisonous newts (so they can survive), and the “new” newts drive selection for higher resistance in snakes.
