Answer:
FALSE
Explanation:
These countries do not have large oil reserves and are major importers of this type of energy. Japan in particular has a shortage of fossil fuels. Given the geopolitical and economic importance of Japan and western European countries, the energy demand of these countries is huge and this makes the trading of oil a fundamental issue for the functioning of the economy of these countries.

#4- Homo sapiens
Explanation:
Homo habilis- Earliest humans also known as "handy man"
Neanderthals- were mainly in Europe and some parts of Asia
Denisovans- Cousins of Neanderthals who were in Asia
Hom sapiens- scientific name for the earliest modern human or "wise people"
The neurotransmitters in a synapse are stored in vesicles located in the presynaptic neuron. These neurotransmitters are released into the synaptic cleft to bind to the postsynaptic neuron for signal transmission.
In a synapse, neurotransmitters are located in vesicles found in the presynaptic neuron. Neurotransmitters are chemical messengers that transmit signals across a synapse, the small gap between neurons. The presynaptic neuron is the sending neuron which releases neurotransmitters from vesicles into the synaptic cleft, where they can then bind to receptors on the postsynaptic neuron, or the receiving neuron, to transmit the signal.

Neurotransmitters are stored in vesicles located in the presynaptic neuron. They are released into the synaptic cleft during signal transmission and eventually taken up by the postsynaptic neuron or cleared from the synapse through various mechanisms.
In a synapse, neurotransmitters are stored in vesicles primarily located in the presynaptic neuron. These vesicles release their neurotransmitters into the synaptic cleft when an action potential (signal) arrives at the terminal button of the neuron. This neurotransmitter then diffuses across the synaptic cleft and binds to receptor proteins on the postsynaptic neuron, leading to further action potentials in the new neuron if the signal is strong enough. Once the signal is delivered, excess neurotransmitters in the synaptic cleft are either broken down, drifted away, or reabsorbed in a process known as reuptake, in order to clear the synapse and regulate production of neurotransmitters. This process provides a clear on and off state between signals and helps in maintaining proper functioning of neurons.
