My final answer is C.increased use of plastics.
Hope this helps!
C. The cell took in another ancient prokaryotic cell, which began living inside it.
Answer:
Generally, K+ ions ensures re-polarization of the membrane potential. It always ensures that the neuron returns its resting state, protecting the neurons and ensuring episode of rest before the next action potential.
K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.
Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.
Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.

4 cells will result. Each cell will have 20 Chromatids which is half a chromosome. once sexual reproduction takes place, these 20 chromatids will match with those from the other parent cell to form chromosomes
