What conditions made the hydrothermal springs the likely place for the Deginning of life? Relate the conditions of the early oceans to the likely metabolism of the first cells B. What is the source of the two organelles in eukaryotic cells that orniginated in endosymbi nd what function is performed by each of these organelles?Explanation / Answer
Answer A
Hydrothermal are attractive in that they supply the gaseous components such as CO2, CH4, and nitrogen species from which organic molecules can form and that they supply nutrients for the metabolism of organisms, such as P, Mn, Fe, Ni, Se, Zn,
hydrothermal provided an ideal environment with all the ingredients needed for microbial life to emerge on early Earth
hydrothermal proto-metabolism," says it provides further indication that life is present and widespread below the seafloor which is very exciting. By methanethiol forming as a breakdown product of microbial life

The hemoglobin which is present in the worms combines with hydrogen sulfide and then gives this product to the bacteria.
