Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter. Many organisms use carbon to make calcium carbonate, a building material of shells and skeletons
Answer:
C, there is genetic variation within the population
Explanation:
Answer:
Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize. One particular species, Prochlorococcus, is the smallest photosynthetic organism on Earth.
Explanation:
Answer:
The answer is B- 12
Explanation:
The glycolysis of one glucose molecule produces two acetyl CoA molecules, the reactions in the glycolytic pathway and citric acid cycle produce six CO2 molecules, ten (10) NADH molecules, and two (2) FADH2 molecules per glucose molecule. Therefore the total number of NADH + FADH2 molecules produced is 12.
