Please answer this: I read this background article the other day: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in - ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane, with two carbon atoms. The chemical formulas and properties of methane, ethane, and several other alkanes are listed in Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally have higher boiling and melting points. I am facing a new situation today: Vic and Joe studied chemistry in school. Joe studied alkanes, while his friend Vic studied other acyclic hydrocarbons. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend studied more about methane gas?

Answer: Vic
Problem: I read this background article the other day: Plants can grow as much as 50 percent faster in concentrations of 1,000 ppm CO2 when compared with ambient conditions, though this assumes no change in climate and no limitation on other nutrients. Elevated CO2 levels cause increased growth reflected in the harvestable yield of crops, with wheat, rice and soybean all showing increases in yield of 1214% under elevated CO2 in FACE experiments.Increased atmospheric CO2 concentrations result in fewer stomata developing on plants which leads to reduced water usage and increased water-use efficiency. Studies using FACE have shown that CO2 enrichment leads to decreased concentrations of micronutrients in crop plants. This may have knock-on effects on other parts of ecosystems as herbivores will need to eat more food to gain the same amount of protein.The concentration of secondary metabolites such as phenylpropanoids and flavonoids I am facing a new situation today: Jerry and Gary each live in separate cities, but both run equally sized farms that grow the same produce. The cities they live in have very similar environments with the only difference being that the CO2 levels in Jerry's town are elevated, and in Gary's they are not. Jerry and Gary regularly talk on the phone and compare notes with each other since their farms are so similar. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will there be more or less micronutrients on Jerry's crops?

A: less
Problem: Given the question: I read this background article the other day: Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering. I am facing a new situation today: Rob is an environmental scientist. He is looking at two samples of soil, sample A and sample B. Sample A is from Amazon Rain-forest, where they get one of the highest rainfall in the world. Sample B is from the Atacama Desert, where they get one of the lowest rainfall in the world. He needs to determine the properties of these samples. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would new surfaces be exposed or stay covered in sample A?

The answer is:
exposed
input question: I read this background article the other day: Gibberellins are hormones that cause the plant to grow. When gibberellins are applied to plants by scientists, the stems grow longer. Some gardeners or horticulture scientists add gibberellins to increase the growth of plants. Dwarf plants (small plants), on the other hand, have low levels of gibberellins ( Figure below ). Another function of gibberellins is to stop dormancy (resting time) of seeds and buds. Gibberellins signal that it's time for a seed to germinate (sprout) or for a bud to open. I am facing a new situation today: Jeffrey is an avid grower of plants and he currently has some daisies and roses in his bedroom. Jeffrey's friend Robert gives Jeffrey a bottle of gibberellins one day and tells Jeffrey to pour some of the bottle onto the daisies. Jeffrey doesn't question this, because he is very trusting of his friend Robert, and pours the gibberellins onto the daisies, but not onto the roses. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Seeds and buds from which plant, the daisies or the roses, will now stop being dormant????
output answer: the daisies
I read this background article the other day: When soil is flooded, hypoxia develops, as soil microorganisms consume oxygen faster than diffusion occurs. The presence of hypoxic soils is one of the defining characteristics of wetlands. Many wetland plants possess aerenchyma, and in some, such as water-lilies, there is mass flow of atmospheric air through leaves and rhizomes. There are many other chemical consequences of hypoxia. For example, nitrification is inhibited as low oxygen occurs and toxic compounds are formed, as anaerobic bacteria use nitrate, manganese, and sulfate as alternative electron acceptors. The reduction-oxidation potential of the rhizhosphere decreases and metal ions such as iron and manganese precipitate. Aerenchyma is a modification of the parenchyma. I am facing a new situation today: Owen inherited two pieces of land. The Eastern land was covered in wetlands, not very good for building or farming on it, but the Western land had a good rich soil good for agriculture. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which land had fewer soil microorganisms consuming oxygen faster than diffusion occurs?
----
Answer: Western
Q: I read this background article the other day: The water level is seasonal, being lowered by about 10 feet (3.0 m) over the winter. The reservoir fills in the spring from snow melt and underground springs. The lake is usually at full level by late spring, but in the occasional years of low snow melt and low rainfall, it may remain up to several feet below its typical level. Water is let out of the lake in the fall so that ice will not damage docks and other structures around the lake. This also leads to excellent water quality, as a significant portion of the water is replaced every year. I am facing a new situation today: The water level in Large Lake was high in March, 3 feet higher in April, and 7 feet higher still in May. It dropped to a much lower level in September, October and November, when they released a significant portion of the water as a yearly chore. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: When was the water level lower, in April or in May?
A:
in April
