Write an abstract of the article below in Results (around 3-4 sentences): RESULTS AND DISCUSSION For the duplicate sets of reactors in experiments A and B, reactors inoculated with Pond 1 started gas formationsooner and peaked earlier than the Pond 2 and Horse Dung reactors. For both sets of reactors, the reactor seeded with pond bottom soil obtained from Pond 1 had the highest methane generation rate, as well as the largest cumulative volume of methane, followed by Pond 2 and finally the reactor seeded with Horse Dung, as shown in Figure 1(A) and (b) below. The possible reason is that Pond 1 is an older pond compared to Pond 2, and the bottom soil obtained from the Pond 1 may have more stable organic matter accumulated as well as higher nutrient concentrations, leading…

16) The following statements concern organisms called stromatolites. Which statements are true and which are false? Correct the false statements. The oldest fossil stromatolites are between 3.5 and 3.9 billion years old. No stromatolites are alive today. Ancient stromatolites were composed of microbial mats layered with sediments. The first stromatolites could fix CO2, but they did not produce O2. Stromatolites form around deep sea vents. Another name for stromatolites is “banded iron formations”. 17) Multicellularity is an important evolutionary innovation in the history of life on Earth. For the following statements, designate which is true (T) and which is false (F). Correct the false. Multicellularity has evolved independently a few times in the history of life. Multicellular members of domain Eukarya arose through the process of endosymbiosis. Multicellular organisms have cells specialized for different functions, with each cell type…
