If you wanted to try and identify or classify archaea or eubacteria, you would _____
study their habitat
study their genetic make-up
study their shape and arrangement
conduct Gram staining
study how they gain energy and nutrients
study how they move
Answer: study their habitat
study their genetic make-up
conduct Gram staining
Step-by-step explanation:
Study their habitat: The members of domain Archea can be identified easily as these organisms are thermophiles and halophiles which means they can be found in extreme heat and extreme saline conditions. Eubacteria are prokaryotic organisms that can be found everywhere on planet Earth.
Study their genetic make-up: Although the members of domain Archea and domain Eubacteria are prokaryotes but they can be identified as separate organisms through their genetic-make up.
Conduct Gram staining: The cell membranes of the Archea do not possess peptidoglycan thus they take up the gram negative stain. The eubacteria may take up gram positive or gram negative stain.
