Answer is D cilia are absent in plant cells
Answer:
The correct answer is - negative.
Explanation:
Cl- ion is more concentrated outside of the cell, as it is given 140 and therefore it will try to move to the inside of the given cell as inside ion concentration is low.
At last, the diffusive force will be get to equilibrium due to an electrostatic force pulling Cl- ions back out of the cell. At this equilibrium point, Cl- ions will moved towards to the the neuron and cause the membrane potential to be more negative.
