Transcranial magnetic stimulation also known as repetitive transcranial magnetic stimulation. TMS is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. In TMS, brain cells are stimulated using a powerful magnetic field produced by a wire coil placed on a person's head that temporarily inactivates neural circuits. TMS devices operate completely outside of the body and affect central nervous system activity by applying powerful magnetic fields to specific areas of the brain that we know are involved in depression.
Cell have to spilt themselfs apart to make more cells for the system. Tree are like cells because they sometimes have seeds in them that help generations of trees grow!
transgenic organism has a specific desirable gene transplanted to another organism. so the first step is to identify the desirable gene. ans is D. Find a gene in one species that would be useful if added to the DNA of another species.
