n many cells, when ACh binds to the ACh receptor protein it opens a set of channels thatconduct Na and K equally well. It is thought that both species of ions move throughthe very same channels. Because the conductanceto both ions are equal, you canassume that permeabilities to Na and K are equal to each other and set them equal to 1in the Goldman equation. What will Vm be in the cells that respond to ACh if thechannels stay open long enough for the system to reach equilibrium

looks like the answer is     c     to me!

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'

d. planting trees

the trees take in carbon to make oxygen.
