- Name two advantages of using intramuscular EMG electrodes compared to traditional surface EMG electrodesarrow_forwardMrs. Elaine Markus is a 37-year-old woman with a history of migraine headaches and visual field disturbances. She has a left medial lower quadrant defect (an area of reduced visual function) that was noted in December of 2014 and has been stable. She recently developed a right temporal lower quadrant defect, which was first noted in September of 2019 and has had worsening symptoms in October. Prior Imaging An MRI in November showed a normal study of the brain including visual cortex and periventricular white matter, with a normal study of the orbits, optic nerves, and extra ocular muscles. A pituitary microadenoma (small benign tumor of the pituitary gland) of approximately 3 mm on the left side of the gland was found with no compromise of the optic chiasm. Mrs. Markus underwent further evaluation by MRI with pituitary cuts and the microadenoma was again noted left of midline causing no compression of the optic nerves nor invasion of the cavernous sinus. The microadenoma is…arrow_forwardWhich is produced first a gametophyte or sporophyte in plant productionarrow_forward
- Differentiate between photochemical process and photophysical process.arrow_forwardPhotochemical activation is much more selective, allowing only one type of molecule to be excited (photochemical reactions), while raising the temperature increases the E of all molecules present (chemical reactions). Is this statement correct?arrow_forwardChoose the 2 incorrect statements. Hfr lacks an F episome, so normal conjugation cannot occur. Natural transformation occurs only in specific strains. Gene mapping can be performed using conjugation and transduction. Complementation studies can be conducted using an F' episome. Temperate bacteria enter the lysogenic cycle.arrow_forward
