Well, Carbon has 4 Valence Electrons. I'm sure you know this, but valance electrons allow electrons to covalently bond with one another. The elements, when sharing the electrons, want to have 8 valance electrons. So carbon has 4 valance electrons so it can bond with itself, or another say 4 hydrogen [becuase hydrogen can live with 2 valance electrons]. Hope this helps. Remember: Electrons <3 8 valance electron bonds Carbon's 4 + Carbon's 4= 8 true love at first bond! OR Carbon's 4+ Hydrogen's 1 [x4] = 8 hope this help
The aspect of his experimental process which is most important for obtaining reliable results is repeating his data collection many times.

Answer: summation
Explanation:
The process which determine if an action potential will be generated or not depends on the combined effects of the signal inputs from multiple sources of synapse or from the repeated signals from the same synapse.
If the input signals reach the threshold voltage, action potential will be generated. (all –or –none principle).Therefore, this process is a determinant of the likelihood of action potential generation and it is called summation.
Summation is the ability to integrate multiple PSPs at multiple synapses.it is the process that determine if an action potential will be generated by combined effects of inhibitory or excitatory signals.
Based on the pathways and voulme of applied stimuli in the presynaptic neuron;
The signals can be temporal summation ( consecutive signals produced from the same synapse)where action potential of high frequency in the PSN generated action potential in the post synaptic neuron, which summate with one another. Or Spatial where signals inputs are from multiple presynaptic cells.
