A new organism was discovered in a deep sea vent at the bottom of the ocean. The researchers collected the sample and made careful observations of it. The picture at right shows a microscopic image captured at 1000X its actual size. Below are some other observations made: • When DNA was isolated from the cell, it was mixed with an equal portion of histone proteins • There are no visible organelles present inside the cell • The specimen seem to die in the presence of oxygen • Able to live in conditions that mimic deep sea vents without any external food source provided Based on these observations, determine each of the following and provide a clear rationale. A) To which domain would you assign this organism? Why? B) Propose a hypothesis of how they obtain nutrients. Are these most likely autotrophs or heterotrophs? Provide a rationale.
