Which of the following statements about members of the family enterobacteriaceae is not true? it includes many medically relevant bacteria. members only reside in the intestinal tract of humans. it includes e. coli, enterobacter, salmonella, and shigella. members are facultative anaerobes. all of the choices are correct.

The correct answer will be option- All of the choices are correct.

Explanation:

Enterobacteriaceae are a group of bacteria belonging to a large family.

The group includes gram-negative and non-spore forming bacteria mainly like E. coli, Salmonella, Shigella, Enterobacter and Yersinia pestis. The main habitat of these bacteria is the lower gastrointestinal tract of various animals, the reason they are also known as 'enterics".

They are facultative anaerobes and feed on the carbohydrates like sugar and nitrates present in the tract. They ferment the sugars and reduce the nitrates to nitrites. many strains and species of these bacteria are used in the clinical department.

Thus, option- All of the choices are correct is the correct answer.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.

a compound light microscope is used to magnify objects in steps.
