<u>The resting </u><u>membrane</u><u> potential would become </u><u>more positive</u><u> because researchers are taking negatively charged molecules out of the cell.</u>

Which methods were used to record the resting membrane potential and action potential of the squid axon choose all that apply ?

  • The squid axon's action potential and resting membrane potential were captured using the following experimental strategy.
  • Using a recording microelectrode inside the cell that is connected to a second electrode outside the cell .

What is cell membrane ?

  • All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
    A semipermeable lipid bilayer makes up the cell membrane.
  • The movement of materials into and out of the cell is controlled by the cell membrane.

What are the functions of a cell membrane?

  • The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out .
  • second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

Epsom salts are solutes that do not pass through cell membranes. If one soaks in a hypertonic solation of Epsom salts, which of
IceJOKER [234]

Answer:

B

Explanation:

The net movements of water from the region of higher water potential  to the region of low water potential through  a selectively permeable membrane is osmosis. It is a form of diffusion which involves the transport of water molecules.

In this present scenario  water molecules  pass through the selectively permeable membrane from higher water potential in the body, to lower water potential but high solute potential (Epsom salts). The later is called an hypertonic solution,this is because it has higher solute potential ,thus higher salt concentration than the surrounding medium,therefore water pass by osmosis into the Epsom salts.

If one is placed in this solution,the cells shrink as they lose water to the more concentrated Epsom.(hypertonic solution)

However, the body homeostatic mechanism through the kidney  ensure re-absorption of fluid back to the body from the DCT  and CT, via  anti diuretic hormone to preserve the cell and the person.
