A bacterium is inoculated into a tube of thioglycollate and incubated. After incubation, turbidity appears throughout, top to bottom, with the greatest turbidty at the very top. This bacterium would be called a(n).

The question is incomplete is incorrect as it does not the options which are:

a. psychrotroph

b. facultative anaerobe

c. microaerophile

d. obligate aerobe

e. aerotolerant microbe

B) facultative anaerobe

Explanation:

The thioglycollate medium is a medium used to prepare the aero-tolerance or how the bacteria respond to the air or the presence of the oxygen.

The thioglycollate molecule reduces the amount of the oxygen in the water and the oxygen from the tube containing the medium is removed via autoclave.

But some oxygen comes again from the atmosphere therefore the bacteria are now able to utilize the oxygen and also lives in the absence of the oxygen. Such bacteria are known as the facultative anaerobe .

Thus, Option-B is correct.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.
