Which is a true statement?
a.The sodium - potassium pump moves sodium and potassium down their concentration gradients.
b.Molecules stop crossing the membrane once equilibrium is reached
c.Water moves from a hypotonic solution to a hypertonic solution during osmosis
d.Cytolysis is common in plant cells.

Respuesta :

Answer:

Im pretty sure its C

Explanation:

Water does move from a lower to a higher concentration during osmosis and a hypotonic solution is a lower concentration and a hypertonic solution is a higher concentration.

Answer:

The true statement is water moves from a hypotonic solution to a hypertonic solution during osmosis.

Explanation:

Osmosis involves the passage of water from a space with a lower concentration of solutes to one with a higher concentration, passing through a semi-permeable membrane.

The phenomenon of osmosis is due to the presence of a concentration gradient, given by the differences in the amount of solutes dissolved in two solutions.

Once the equilibrium of concentrations has been established on both sides of the membrane, the concentration gradient disappears.

Other options are not true:

    a. Despite the difference in concentration of the sodium and potassium ions outside and inside the cell, the sodium-potassium pump responds to an active transport mechanism.

    b. Molecules do not stop crossing the membrane once equilibrium is reached .

    d. Plant cells can protect themselves from cytolysis thanks to the existence of the cell wall, so this phenomenon is not fecund.
