Can archaebacteria live without oxygen
How do each of these events map onto geologic time? Most of them are not “instantaneous” events, and so they span multiple time periods as follows: 1. Hadean eon (4.6-4 BYA): No life present on Earth 2. Archean eon (4 to 2.5 BYA) 2.1. Origin of life (prokaryotic, anaerobic), 2.8-2.6 BYA 2.2.

Living things as diverse as bacteria, archaea, algae, fungi, protozoans, animals, and plants all consist of one or more cells. Cells are made up of components that help living things to eat, respire, excrete wastes, and perform all of the necessary functions of life.

WebThe two prokaryote domains, Bacteria and Archaea, split from each other early in the evolution of life. Bacteria are very diverse, ranging from disease-causing pathogens to beneficial photosynthesizers and symbionts. Archaea are also diverse, but none are pathogenic and many live in extreme environments. Weba. All extremophiles are in the Archaea domain. b. All Archaea are considered extremophiles. c. Extremophiles can survive without oxygen. d. Extremophiles are similar to types of bacteria. e. Extremophiles may have been some of the earliest living organisms on Earth. Problem 2.
WebAbout 21% of Earth’s atmosphere is oxygen, and most of the rest is nitrogen. But it hasn’t always been so. When life first arose (likely more than four billion years ago), there was no free oxygen in the atmosphere at all. Life was anaerobic, meaning that it did not need oxygen to live and grow.
