An electrical synapse provides channel of proteins referred to as gap though which two neurons are connected. This connection allows the electrical signal to travel from cell to the other. Electrical synapses are commonly found in the brain and nervous system of an organism
In this synapse, there is a passive flow of ions from one neuron to the other through the gap junction pores. The neuron from which the current flows is called as presynaptic element and is also referred to as upstream neuron while the neuron which receives the current is called as postsynaptic or downstream neuron.
<span>Synapses in which gap junctions allow ions to diffuse quickly from cell to cell are called ELECTRICAL synapses. An electrical synapse is a mechanical and electrically conductive link between two neighboring neurons that is formed at a narrow gap between the pre-synaptic and post-synaptic neurons known as a gap junction.</span>
The answer is 4) determining the true age of rock layers.
Relative dating is only used to determine the rocks in sequential order from oldest to newest, absolute dating can give an estimated time to the age of the rock.
<span>The answer is A.
The wildfire decimates abiotic and biotic
factors in a populations' habitat hence reducing the resources
required to sustain the entire population. This devastates the population numbers
due to increased competition for reduced
resources. Wildfire especially decimates
primary producers hence affecting the organisms up the food chain. </span>
