Please answer this: I can use this background: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. Now, I have a new situation: Two groups of microbiology students studied about the fermentation process. Group A studied about alcoholic and acetic fermentation, while group B studied about lactic fermentation. Answer this question please: Which group learned more about fungi?
++++++++
Answer: group B

Please answer this: I can use this background: Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. Now, I have a new situation: Guyana and Nigeria had thriving economies. Guyana's economy was based on conventional agriculture, while Nigeria attracted an enormous number of tourists to its splendid beaches each year. Answer this question please: Which country caused less human-created waste floating in a body of water?
++++++++
Answer: Guyana

Please answer this: I can use this background: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid. Now, I have a new situation: China used alternative fuels to generate electricity, while Mongolia burned lots of fossil fuels. There were frequent debates between the two countries on this matter. Answer this question please: Which country released fewer anthropogenic emissions?
++++++++
Answer:
China
