The specificity of signaling pathways may include which of the following : Group of answer choices the ability to be switched off instantly by hydrolysis of a single phosphate-ester bond flippase-catalyzed movement of phospholipids from the inner to the outer leaflet. the assembly of large multiprotein complexes phosphorylation of target proteins at the hydroxyl of certian amino acid residues. migration of signal proteins into membrane rafts.

wheres the answers ?

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.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
