Which statement describes the synapse?
it is the gap between neurons that ensures that information travels in multiple directions.
it is the gap between neurons that ensures that information travels in one direction only.
it is the part of the neuron that carries information through electrical impulses to the cell body.
it is the part of the neuron that carries information through chemical impulses to the cell body.

When an action potential reaches presynaptic terminal on a neuron, it will induce a release of neurotransmitters from the neuron. Neurotransmitters pass through the synaptic gap and bind to the receptor on the postsynaptic neuron. Thus, information travels in one direction only.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.
