(b) The experiment reveals a potential mechanism for action potential transmission in other nerve cells. (c) The findings imply a mechanism for action potential transmission in other nerve cells. (d) Further studies are required on the membrane properties of neurons from various species to validate the squid axon's findings. (e) Additional research on the membrane properties of neurons from other species is necessary to confirm the squid axon's findings. **(b) The experiment reveals a potential mechanism for action potential transmission in other nerve cells.** **(d) Further studies are required on the membrane properties of neurons from various species to validate the squid axon's findings.** **What methods were used to record the resting membrane potential and action potential of the squid axon? Choose all that apply.** - Using a separate stimulating electrode to depolarize the nerve cell to its threshold potential. - Applying a separate stimulating electrode to hyperpolarize the nerve cell to its threshold potential. - Placing a recording microelectrode inside the cell referenced to a second electrode located outside the cell. - Placing a recording microelectrode adjacent to the outside of the cell referenced to a second electrode. **- Using a separate stimulating electrode to depolarize the nerve cell to its threshold potential.** **- Placing a recording microelectrode inside the cell referenced to a second electrode located outside the cell.** **Which statement serves as an alternative hypothesis for the experiment?** (a) Changes in membrane potential resist movements of charged ions across the membrane.
