Professor Chavez is teaching a large seminar class about the human nervous system, and decides to try an interactive demonstration. He asks one student, Marcia, to stand up and walk to the middle of the room. "Marcia is a neuron, everyone," Professor Chavez says. "How many of you would have to stand up and surround Marcia to reflect the number of glia cells that exist for every single neuron in the human nervous system?" The students will be correct when students get up and stand around Marcia.

10                                              

Explanation:

Glia cell is also referred as "neuroglia" or "glial cells" and is described as different "non-neuronal cells" that are being present in an individual's "central nervous system" i.e, the spinal cord and the brain as well as the "peripheral nervous system" and it doesn't produce or create "electrical impulses".

Glia cells are responsible for forming myelin sheath, maintaining homeostasis, and providing protection & support to the neurons.

As per the question above, when 10 students will surround Marcia then it will be correct in demonstrating the glia cells around a specific neuron.

b) the planets year length would be longer

hope this !
