For staining flagella of bacteria use actively motile organisms 20 to 24 hours old, allow to diffuse in sterile water 20 to 30 minutes, transfer droplets of the suspension to clean slides and let evaporate without spreading. Then treat 2 to 4 minutes with the following mordant: tannic acid 10 or 20%, 50 cc.; ferric chloride 5%, 10 to 15 cc.; carbol fuchsin (Ziehl-Nielson), 5 cc.; hydrogen peroxide 3%, 6 to 8 cc. Wash and stain 2 to 3 minutes with a mixture of basic fuchsin, saturated alcoholic, 10 cc.; anilin oil (1 part) and 95% alcohol (3 parts) mixed, 5 cc.; distilled water, 30 cc.; acetic acid, 4%, 1 cc. Wash thoroly with water.
Answer:
b=6
Explanation:
f(x)=x3 - 3x2 + bx - 6
f(3)=27-27+3b-6
0=3b-6
3b=6
therfore
b=6/3
b=6
plz amrk me as brainleiest
Answer to question four is B
Yes. Currently we are going through global warming causing it to be cold one minute and hot the next
At the interface of two fluids, there is a difference in pressure. This leads to the existence of a surface force, the surface tension, that shapes the fluid.
The surface tension of water is roughly 72 dynes/cm,
However, that is highly dependant on the characteristics of the considered material (physical and chemical), and thus all fluids (and thus liquids) do not have the same surface tension.
