Salvador would like to take a paternity test to determine if he is pilar’s father. he asks pilar’s mother, antonia, to provide dna samples for both her and pilar. which technique will most likely be used to compare the three dna samples?

d. Autoradiographies

Explanation:

Based on the information provided within the question it can be said that the technique that is mainly used for this are Autoradiographies. This is a technique that is mostly used for X- ray film to visualize molecules or fragments of molecules that have been radioactively but are also used for  analyzing the length and number of DNA fragments using a special method called gel electrophoresis which is then used to compare the various DNA samples.

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.
