Assume a single-celled organism was discovered in water above 100°C.  On closer inspection, it is determined that this organism is classified under the Archaea domain.  Given this information, this organism most likely has:A.a peptidoglycan layer in its cell wall.B.a circular chromosome.C.telomeres.D.an endoplasmic reticulum.

When a water sample from a hot thermal vent was tested, it was found to contain a single-celled organism having a cell wall lacking a nucleus. What is its classification most likely?(a) Eukarya(b) Fungi(c) Protista(d) Archaea

Scientists have discovered a new cell near a very hot water vent at the bottom of the ocean. This cell has no mitochondria, and it has a cell wall that lacks peptidoglycan. What kind of cell is this most likely to be?Group of answer choicesFungiAnimalPlantBacterialArchaea

You identify a novel living organism that needs to be classified into one of the three domains of life. The organism has a cell wall containing pseudopeptidoglycan (pseudomurein), a plasma membrane, and a nucleoid region. Based on this information, which of the three domains would be the correct classification?ANSWERProkaryotesBacteria and ArchaeaBacteria onlyArchaea only

What is the major cell wall component of the members of Domain Archaea?CelluloseChitinPeptidoglycanPseudomurein

1. Organisms with prokaryotic cells are separated into two domains, Bacteria and Archaea.target 1 of 82. Protistsare the most diverse and widespread prokaryotes.target 2 of 83. Most of the prokaryotes known as archaealive in extreme environments, such as salty lakes.target 3 of 84. All organisms with eukaryotic cells are grouped in domain Eukarya.target 4 of 85. Bacteriaare a diverse collection of mostly single-celled eukaryotes, which are sorted into several kingdoms to reflect their evolutionary relationships.target 5 of 86. Kingdom Plantae consists of multicellular eukaryotes that produce their food by photosynthesis.target 6 of 87. Kingdom Fungi includes eukaryotic organisms that mostly decompose organic wastes and absorb nutrients into their cells.target 7 of 88. Kingdom Animalia consists of multicellular eukaryotes that obtain their food by ingesting (eating) other organisms.
