A falcultative anaerobic organism is able to perform aerobic respiration in the presence of oxygen and fermentation in the absen

ce
of oxygen. An example of a falcultative anaerobic organism is brewer's yeast, which is used in the production of alcoholic
beverages. If sealed in a vessel containing oxygen gas, water, and sugar (glucose), the yeast will eventually deplete the oxygen
gas. As long as glucose is available, however, the yeast can still survive.
Brewer's yeast use oxygen preferentially because???

Cyanobacteria can cluster together into colonies called _______, with some discovered in Western Australia that are 3.5 billion
Anna [14]

Answer:

1.) stromatolites

2.) photosynthesis

3.) Ordovician

4.) Cambrian

5.) oxygen

6.) As Earth cooled, carbon dioxide dissolved in the early ocean. Cyanobacteria consumed carbon dioxide and converted it to oxygen. Methane was removed from the atmosphere as oxygen was produced, eventually leading to the Cambrian Explosion.

7.) Metabolic processes that use oxygen produce more energy than anaerobic metabolism. Simple diffusion of oxygen would limit the size of a multicellular eukaryote, but animals evolved ways to transport oxygen to their tissues, which permitted an increase in size.

Which culturing method proivded the clearest results, the semisolid medium tube or the soft agar plate?
sattari [20]
The answer to this question would be soft agar plate.

The semisolid medium tube is mostly used for containing the specimen. It is hard to examine semisolid medium since the bacteria can grow in the upper part, middle part or even the lower part of the medium. In agar plate, the bacteria always growth in the upper part so it is easier to count the bacteria.
But semisolid can give some more information in determining whether the bacteria is anaerobic by looking for bubble inside the medium. Anaerobic bacteria can do fermentation that will produce air.
