The ability to obtain energy via the oxidation of reduced sulfur compounds (e. g., H2S) is widespread among prokaryotes (both Bacteria and Archaea). Unfortunately, the nature of the major reaction end product has what effect on the immediate environment?

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

the fossil record provides evidence of a common ancestor to many species.
