Fichas del conjunto (7)
- 1What are obligated aerobes?Organisms that require oxygen for cellular respiration
- 2What are obligated anaerobes?Organisms that are poisoned by oxygen and use fermentation or anaerobic respiration instead
- 3What are facultative anaerobes?Organisms that can survive with or without oxygen
- 4What are prokaryotes role in nitrogen fixation?Some prokaryotes fix the nitrogen by converting atmospheric nitrogen N2 into ammonia NH3 that other organisms can use too
- 5What is metabolic cooperation?Cooperation between prokaryotes allow them to use environmental resources they couldn't use as individual cells. Bio films for example are many prokaryotes working together to survive
- 6How has systematics in prokaryotes changed?Until the 20th century prokaryotic taxonomy was based on phenotypic criteria. At this time molecular systematic started to be used instead in prokaryotic phylogeny which worked better.
- 7What is an unresolved tricotomy?When we don't the exact rider of ancestors, meaning we also don't know the clad order in the cladogram
