Answer:

Bigger brain helped our ancestor survives.

In a simple synapse, neurotransmitter chemicals are received by _______. A. the presynaptic membrane B. dendrites C. axon hilloc
artcher [175]

Answer:

In a simple synapse, neurotransmitter chemicals are received by the postsynaptic neuron.

Explanation:

The presynaptic membrane is where neurotransmitters are generated, whereas the postsynaptic membrane is where the neurotransmitter receptors have been located. The axon terminal is substantially far more structurally complicated at a neuromuscular junction.

Axon Hillock performs administrative duties by adding up all incoming signals, including inhibitory and stimulating. The action potential gets activated if this total surpasses the limiting threshold.

The neuron's cell body controls the structure of the neuron, houses its genetic material, and supplies energy for its various functions. Additionally, the dendrites' receiving information is processed by the cell body.

Dendrites gather and retain all data coming from the terminal of the axon. Dendrites get any incoming data or signals from the other neuron.

And natural selection is the concept of "survival of the fittest" where the organisms with the best adapted traits in an environment live long enough to pass on that best adapted trait to their offspring.
