Answer:
Electrolytes are nothing but minerals that have electric charge when it is mixed in liquid like blood. thus the sodium and potassium electrolytes will help regulate the nerve and muscle function. They also maintain the acid-base balance by regulating the electric charge on the cells and water flow across the membrane.

E. All of the above
Explanation:
In cardiac contractile cells there is rapid depolarization, then a plateau phase and repolarization.
when an action potential stimulates the cell, voltage-gated channels open quickly commencing the positive-feedback mechanism of depolarization. This in turn raises the membrane potential to approximately +30 mV, and this closes the sodium channels. Next comes the plateau phase, where membrane potential declines relatively slowly due to the opening of the slow Ca2+ channels, allowing Ca2+ to enter the cell while few K+ channels are open, leading to K+ to exit. Once the membrane potential reaches approximately zero, the Ca2+ channels close and K+ channels open, allowing the exit of K+. The repolarization lasts approximately for a while and here is when the membrane potential drops until it reaches resting levels once more and repeats the cycle.
Answer:
0.25
Explanation:
The population of panthers consists of 60 black panthers with the dominanat allele PP. 30 are pink panthers with the genotype Pp and 10 panthers are white with the phenotype pp.
The frequency of p allele in the population can be determined by
the number of individual with pp genotype + 1/2the number of individual with Pp genotype divided by the total number of individual.
Frequency = 10+1/2*30/100
Frequency = 0.25.
Thus, the frequency of p genotype is 0.25.
