The _electroencephalogram (EEG)_ is a device that takes advantage of the changing magnetic fields produced by the electrical activity of the brain to produce a record of neural activity in the awake brain.
After crystal violet staining, the Gram-positive bacteria may appear dark blue or violet. The cell wall of gram positive bacteria have thick peptidoglycan layer, thus it retains the crystal violet stain compared to gram negative bacteria.
Hope this helps! Have a good day!

What is endoplasmic reticulum?
Endoplasmic reticulum (ER), a continuous membrane structure in biology, is vital for the synthesis, folding, modification, and transport of proteins. It forms a series of flattened sacs within the cytoplasm of eukaryotic cells. An endoplasmic reticulum can be found in all eukaryotic cells (ER). The ER typically makes up more than 50% of the cell's membranous composition in animal cells. The two forms of ER, known as rough ER and smooth ER, can be distinguished by differences in certain morphological and functional properties.
