Please answer this: You are given a new situation: Two gardeners started their planting season at the same time. Bill used mycorrizal fungi compost for the garden, while Hank used regular top soil. Bill was very happy with the harvest.  and a hint : A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant’s root system. The larger surface area improves water and mineral nutrient absorption from the soil.  Please answer this question : Which gardener had less fungus with constant and direct access to glucose?

Please answer this: You are given a new situation: Two countries are considering adopting the same currency. Country A will begin to use the currency of Country B if they agree to make this change. Currently there is a 2 to 1 exchange rate on currency from country A to country B but this changes over time. Also in order to exchange the currency you have to pay a 5% fee on whatever the amount is you would like to exchange. Under the new system there will be no exchange rate and there will no longer be a reason to pay the transaction fee as everyone will have the same currency.  and a hint : One of the main advantages of adopting a strong foreign currency as sole legal tender is to reduce the transaction costs of trade among countries using the same currency.[13] There are at least two ways to infer this impact from data. The first is the significantly negative effect of exchange rate volatility on trade in most cases, and the second is an association between transaction costs and the need to operate with multiple currencies.[14] Economic integration with the rest of the world becomes easier as a result of lowered transaction costs and stabler prices.[2] Rose (2000) applied the gravity model of trade and provided empirical evidence that countries sharing a common currency engage in significantly increased trade among them, and that the benefits of currency substitution for trade may be large.[15]  Please answer this question : Which Counties currency is worth more?

Please answer this: You are given a new situation: Ted and Larry studied environmental sciences. They are learning about greenhouse gasses this week. Ted reads about carbon dioxide, while Larry reads about methane gas.  and a hint : 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.  Please answer this question : Which student read less about anthropogenic emissions?
++++++++
Answer:
Larry
