Cultures of a bacterial species were incubated on the shelf of a refrigerator (5 C), out on a lab bench top (22 C), on the shelf
Setler79 [48]

D) Psychrotrophs.

Explanation:

  • Psychrotrophs are those bacteria which can tolerate cold temperature and have optimum growth above 15 degree Celsius.
  • Halophiles prefer high salt concentration.
  • Mesophiles prefer temperatures with a average of 37 degree Celsius.
  • Anaerobes grow in absence of oxygen.
  • In the given experiment, none of the bacterial cultures were placed in saline or anaerobic conditions. So, the bacterial species is not an anaerobe or halophile.
  • Again the cultures did not show growth at 37 degree celsius so they are not mesophiles.
  • Maximum growth at 22 degree celsius and a little growth in refrigerator make it obvious that the species is a Psychrotroph.

Help me please please
natita [175]

Answer:

1) A

2) Could be A, B,  or D

Explanation:

1)   Prokaryote is a single celled organism that has no distinct nucleus, membrane  - bound organelles, and specialized organelles (such as the mitochondria).

This definition would only match A) a bacteria cell because all the other cells are called Eukaryotas (which are more complex and have membrane - bound organelles).

2) The answer could be A because Prokaryotic cells lack membrane bound organelles

The answer could be B because the diagram has labeled the cell membrane as "plasma membrane"

The answer could NOT be C because Prokaryotic cells do not have nucleus's, but have free floating DNA.

The answer could be D because it is the only image that has a flagellum (which helps the cell move)

I am sorry I couldn't answer this question completely, but I think that this question has flaws.

Hope this helps! Let me know if you have any other questions!
