1. When Alaina is working on her bicycle, she brings her entire tool kit out on the driveway and starts pulling wrenches from the tool kit at random, trying them until she finds one that fits. Alaina's approach when she is working on her bicycle could be best described asheuristic
forming subgoals
trial and error
working backward
alternate outcomes analysis
2. When a neurotransmitter is released, but it does not fit into a suitable receptor channel on the postsynaptic neuron the firing potential of the postsynaptic neuron will be inactivated
the strength of the action potential in the presynaptic neuron will increase
the firing potential of the postsynaptic neuron will not be affected
an inhibitory postsynaptic potential will be generated
an excitatory postsynaptic potential will be generated
