Where could the organisms have come from in the 1768 broth experiment described?
the organisms could come from the heat in the broth if you boil it,cause if you boil it,it creates organisms. It will only work if you put a cap on top of the bottle you are boiling. the one with the cap on is not cantaminated. The one without the cap is cantaminated and already has organisms in it.so the organisms come from the oxygen in the one where it does not have the cap on
Why do some microorganisms characteristically form a growth of the pellicle type?
in pellicle formation small masses of cells gather at the top of the nutrient broth. these organisms (masses of cells) are aerobes. the oxgen concentration is greatest at the top which would explain growth of the pellicle type.
How could you tell the bacteria were growing in the culture?
Bacteria growing on a petri dish can have more than one bacteria growing on it, but different characteristics can be seen like cilia, motility and color. To know more specifically what those other bacteria strains are, get a sample and grow it on agar by itself.
Are brothes soup?

How does thioglycollate work?
Thioglycollate broth is an enriched medium used to determine the oxygen requirements of microorganisms. The diffusion of oxygen from the top of the broth provides a range of concentrations.
How do you make moist cornbread?
You can make your cornbread dressing more moist by adding more broth to the recipe. When you pour the dressing into the baking pan, if you have a little broth standing on top, it should turn out moist. Another way is, when you add the broth to the dressing mixture, stir it well, and let it sit for a little while to allow the cornbread to absorb the moisture. Then add more broth. I have also checked the dressing during baking, and if it seems to be getting dry, I drizzle broth over the top and put it back in the oven. The broth you add will absorb into the dressing.

What is the film of cells at the surface of a broth called?
When bacteria are grown in broths such as trypticase soy broth (TSB), they may exhibit patterns of growth ranging from a sediment at the bottom of the tube, turbid growth throughout the tube, or a pellicle (thick growth at the top of the tube).
