All Living Organisms … ◆ Acquire energy & matter from their surroundings ◆ Made of a cell ◆ Have the ability to reproduce ◆ Have populations that can evolve ◆ Respond to the environment ◆ Metabolism that is anaerobic or aerobic ◆ Have DNA ◆ Are carbon & water based Are viruses Alive ? ◆ No ● Not cellular ● Can't acquire energy from surroundings ● Can't respond to environmental stimuli Three Domains of Life : ◆ Eukaryotes ● Have nucleus ● Membr...

Archaea what are they? where can they be found? how do they get energy? - Answer-similar to bacteria since they are also unicellular prokaryotic organisms (lack nucleus/organelles) many are extremophiles (living in extreme salt, pH, or temps) use whatever energy they find (organic compounds, ammonia, hydrogen gas, metal ions, photosynthesis) Symbiotic relationships: mutualistic, parasitic, commensal? - Answer-mutualistic - beneficial to both parasitic - beneficial to one + ha...
