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

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.

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 find a cell of a type you have never seen before. The cell has both a nucleus and a cell wall. Therefore, you conclude that it is likely to be a(n) ________ cell.animalplantbacterialprokaryotic
