Answer: hello your question lacks the options related attached below is the complete question
answer :
A brief positive current inward due to sodium entry through voltage gated sodium channels ( Option 4 )
Explanation:
What you would expect to see following the bathing of a sensory neuron in tetra ammonium chloride and MgCl2, given that the voltage clamp moves from -70 to -5 mV is A brief positive current inward due to sodium entry through voltage gated sodium channels.
This is because as Cl^- enters the cells it causes the entrance of Na^+ into the cell ( i.e. voltage gated Na^+ ions channels will open ) hence the mixture will cause a lower negative membrane potential to be present .
Ranking on hormonal levels presents on mutant ob, db and normal rats parabiosed to either.
(db rat +ob rat) ( db rat + normal rat) (ob rat + norma rat )(normal rat + normal rat )
Rats are ranked according to leptin levels. Leptin levels are directly proportional to the production of adipose fats present.
