A cell is in equilibrium with an outside solution where Ψw = -1.0 bars. Water is added to the outside solution such that Ψw = -0.2 bars and the cell volume increases 1.5 times. What Pressure potential is required to stop the movement of water into the cell?

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
