Organisms that can cause nongonococcal urethritis are classified with _____. One of the primary differences between halophilic Archaea and halophiles in the other domains of life is that Archaea exclusively use the salt-in strategy, whereas almost all other known halophiles use the compatible solutes strategy (Oren 2006). | PowerPoint PPT presentation | free to view Archaea - Archaea Domain belonging to archaebacteria. Many thermophiles are archaea, though they can be bacteria or fungi. Choanoflagellates are single-celled protists with a collar-like structure that resemble cells called choanocytes in sponges. "I know it's supposed to be a ciliate or an amoeba, but how am I supposed to know which it is?" Biology definition: A thermophile is an organism that is adapted to live at relatively high temperatures, about 60 to 140 C (113 to 252 F). They are classified as archaea, one of the three domains of all living beings. Methanogens are classified into 5 groups, depending on their differences in physiological properties, the substrates they need to do the methanogenesis, diet, their form, the way they move, and cell structure. Furthermore, A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015).
