1. Glial cells are refereed to as forgotten cells because the number of scientific research carried out on glial cells is very small compared to the other nerve cells. The other nerve cells in the nervous system have been focus of research for years, this is done in order to better understand human brain; but the glial cells have not receive that same kind of attention from researchers.
2. The following differences exist between neurons ans glial cells:
a. Glia cells has only one process while neurons have two processes, which are axon and dendrites.
b. Glial cells can not generate action potentials while neurons can.
c. Neuron have resting potential; glia cells do not.
d. Neurons possess chemical synapses which use neurotransmitters. Glial cells do not possess chemical synapses.
e. The glial cells in the nervous system are much more in number than the neurons.
3. If the glial cells stop functioning in a human being, the entire nervous system will start to malfunctioning. This is because the roles that the glial cells play in the nervous system are very important ones that are very necessary for the overall functioning of the nervous system.
Answer:
sodium ions is the correct answer
Answer:
A. Methane
Explanation:
Methane is a gas not a solid. Every other answer choice is a solid.
Answer: d. None of the above is false.
Explanation: The reasons are:
Intermolecular forces should be reduced when molecules need to be vaporized, otherwise they will not be converted into vapours.
When the temperature increases, forces of attraction decreases which allows molecules to evaporate because energy will be increased which allows molecule to break bonding between them. Hence increasing temperature has effect on vaporization.
Dispersion forces is the weakest force between molecules and hydrogen bond is strong so molecule having only dispersion force will evaporate at the higher rate.
