Imagine a study that has tested the effects of spider toxins on action potential propagation in axons of crickets. When the toxin is applied to the axon, the propagation of action potentials is modified so that the amplitude of action potentials is reduced by 80% from 90 mV to 18 mV. Voltage-gated sodium and potassium channels are not affected by the toxin. The toxin does not activate or inhibit either one of the two channels that generate the action potential. It cannot be ruled out that an unknown ion channel is targeted by the toxin. What unknown mechanism could cause the 80% reduction in the action potential amplitude in the axon? Explain

Apopulation of rabbits live in a local forest. some had a mutation for a large body and long legs. the graph below shows the number of both the mutant and the normal rabbits over 5 generations. which of the following statements is true for this scenario? question 7 options: the rabbits with the mutation were more successful with restricted food than the normal rabbits. both sets of rabbits were equally successful with the restricted food source.i the normal rabbits were more successful with restricted food than the rabbits with the mutation. the graph does not let us know which rabbit was more successful.
