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

Which is the correct order in the scientific process? ask a question ® form a hypothesis ® make an observation ask a question ® make an observation ® form a hypothesis make an observation ® form a hypothesis ® ask a question make an observation ® ask a question ® form a hypothesis

Explain the cellular functions that occur when antibiotics attack a bacteria cell. a. antibiotics target the cell wall, cell membrane, and the processes of protein and nucleic acids production in bacteria to rupture the cell. b. antibiotics create dormant resistant endospores to preserve the genetic material and rupture the cell. c. antibiotics target the cell wall and form a bridge-like connection to form conjugation. d. antibiotics use binary fission to grow twice its size, replications its dna, and split into two cells.

During convection, less dense fluid rises and denser fluid sinks.
