I'm pretty sure it's heterozygous Rr.
If the stimulus reaches the threshold an action potential will be generated. If the stimulus doesn't reach it no action potential will be generated. If the stimulus will be stronger the action potential will have the same amplitude. The refractory period makes it harder to generate an action potential so they decrease the frequency of action potential production.
Chemoautotrophs made their food by themselves using the energy from the sun. This means that an ecosystem that depends on chemoautotrophs for food is DEPENDENT ON SUNLIGHT FOR FOOD AND SURVIVAL. This is because the chemoautotrophic organisms are the primary producers in that ecosystem.
