Jayden is taking a test. He has to write why scientists support the theory that life began near hydrothermal vents in the ocean.
Which point should he include in his answer? A.
Hydrothermal vents were closest to ocean surface, and therefore could receive oxygen.
B.
Oceans were dry and only had water near the hydrothermal vents in the earlier ages.
C.
Even today, all life forms are first born near hydrothermal vents and they later migrate to land.
D.
Fossils of archeabacteria, which are early common ancestors, were found near hydrothermal vents.
Archaebacteria are early life forms on earth. They utilized the process of chemosynthesis to make organic molecules from inorganic molecules and for energy. The word archae means ‘ancient’ life forms. These single-celled organisms evolved around sulfur-rich environments of the hydrothermal vents.
They have uncoiled to form long, thin strands. Interphase is made up of G1, S, and G2 phases where S is the synthesis phase and G2 prepares the cell for mitosis/meiosis.
