The precambrian era makes up about 90% of the earths history, but there was little to no living organisms at the time other than microscopic ones. The first eukaryotes were found in the cambrian period after the precambrian period, not only that but at the end of the precambrian era in the Proterozoic era there was a mass extinction of about 70-80% of all living organisms
The period you’ve described would be the G2 phase which is considered a “checkpoint” that determines whether or not a cell can enter the mitosis phase
Answer:
Carbon pollution is changing the ocean's chemistry, slowing its ability to uptake CO2, making it more acidic, and harming shellfish and other marine life we depend on. The ocean has absorbed about 29 percent of global CO2 emissions since the end of the preindustrial era.Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming.
