Question

Your teacher gives you an unknown bacterium to observe. Select the method that would help you determine whether the bacterium is a chemotroph.

exposing the bacterium to carbon dioxide to see if it fixes carbon

growing the bacterium in a sulfur solution to see if it breaks the inorganic molecules down

exposing the bacterium to direct sunlight to see if it converts light to chemical energy

growing the bacterium in an agar tube filled with protein to see if it breaks the organic molecules down

Answer 1

Answer:

growing the bacterium in a sulfur solution to see if it breaks the inorganic molecules down

Explanation:

Answer 2

The method that would help determine if the bacterium is a chemotroph is : ( B ) growing the bacterium in a sulfur solution to see if it breaks the inorganic molecules down

Chemotrophs obtains its energy through Carbon dioxide and other inorganic molecules  in its environment . Chemotrophs can be grouped as organic or inorganic and the process of obtaining energy by Chemotrophs is called Chemosynthesis. They are found mainly in places without the reach of sunlight.

Therefore to determine if a bacterium is a chemotroph grow the bacterium in a sulfur solution to see if it breaks down the inorganic molecules which is a source of energy for Chemotrophs.
