Awoman is heterozygous for the cf-associated gene (the alleles are represented here by the letters a and a). assuming that meiosis occurs normally, which of the following represents eggs that she can produce?

As she is heterozygous, her genotype would be Aa. The eggs she produce would have one allele from her genotype, and thus she can produce A or a eggs.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
