Characteristics of fungi living in wood as a group, are polyphyletic under the microscope for education.
Particles, medical concept
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet), ampicillin (red).
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.

Stem of Nerium indicum T.S. under light mircoscope with white background
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
