Question

d. Deatii pilase Ifan organism grows optimally at 500 in 20% NaCl it would be considered a a. Thermophile and alkilophile b. Thermophile and halophile c. Mesophile and acidophile d. Thermophile and obligae anaerobe e. Mesophile and halophile 9. To fix nitrogen refers to the ability of an organism to convert nitrogen gas in the atmosphere to a. NO3 b. NH3 c. CH2N d. CN 10. Assume an organism is able to completely break down the following compounds, would it have everything it needs to survive? Methionine (amino acid that contains C, N, O, H and S) DNA (contains C, N, O, P, H) Mineral water containing NaCI, KCI, FeS04, MgClz, Ca carbonate and other trace minerals a. Yes b. No

Explanation / Answer

8. b. Thermophile and halophile

Since the organism can grow at a temperature more than 40 degrees, so it must be a thermophile. And since it grows in a high concentration of salt NaCl, so it must be a halophile.

9. b. NH3

Nitrogen fixation is the conversion of atmospheric nitrogen to ammonia.

10. a. Yes

Since the basic need of a microorganism is C, N, O, H, P, S, and some trace element. So it has all the things it needs to survive.
