The leak channels allow Na+ and K+ to move across the cell membrane down their gradients (from a high concentration toward a lower concentration). With the combined ion pumping and leakage of ions, the cell can maintain a stable resting membrane potential.
Codominance occurs when the two alleles of a gene are neither dominant or recessive over one another. As a result, both the alleles are expressed and the phenotype shows the traits of both the alleles of the gene. In the scenario discussed in the question, both brown and white coat were seen in the coats of the rabbits because of co- dominance. Both the alleles were being expressed for the trait colour.
Answer – Repetitive Transcranial Magnetic Stimulation (rTMS)
Repetitive transcranial magnetic stimulation (rTMS) is a type
of brain stimulation therapy used in the treatment of depression and anxiety;
it’s most especially used for the treatment of severe depression. During the
procedure, a magnetic field generator (coil) is placed near the head of the
person to deliver repeated pulses of magnetic energy.
