Answer:
At lower temperature, membranes maintain fluidity by having a higher percentage of unsaturated fatty acids.
Explanation:
The fluidity of the membranes is affected by temperature. At lower temperature conditions, tight packing of saturated fatty acids makes the membranes more rigid. Therefore, membranes incorporate a higher proportion of unsaturated fatty acids to maintain the required fluidity. This is why the membrane lipids from the tissue near the hooves have a higher proportion of unsaturated fatty acids as the temperature of the tissues of a reindeer near extremities is lower than that of the tissues from the upper leg.
Okay well the signal or the movement coming through the neuron(and its axon) is about the ions. The ion is a charged like particle, such as Na+ (If you remember that). Na+ is a sodium ion. So most of those ions I was talking about before just simply flow in or out of the cell. I hope this helps! <3
