Problem: Tropical forests (rainforests) receive more insolation and rainfall over longer growing seasons than any other environment on earth. With these elevated temperatures, insolation and rainfall, biomass is extremely productive leading to the production of as much as 800 grams of carbon per square meter per year. Higher temperatures and larger amounts of water contribute to higher rates of chemical weathering. Increased rates of decomposition cause smaller amounts of fulvic acid to percolate and leach metals from the zone of active weathering. Thus, in stark contrast to soil in forests, tropical forests have little to no podzolization and therefore do not have marked visual and chemical contrasts with the soil layers. Instead, the mobile metals Mg, Fe and Al are precipitated as oxide minerals giving the soil a rusty red color. The Farlook forest is classified as a tropical forest, and the Celeste forest is not a tropical forest. Jessica is currently looking for a forest to go camping in and is trying to choose which of these two forests she will visit for a week. Jessica despises camping in the rain and also prefers a more moderate temperature. Luckily, her trip isn't for several months so she has plenty of time to make up her mind. Which forest should Jessica not go camping in?

A: Farlook

Problem: Given the question: Once again, a mutation is the change in the DNA or RNA sequence. In multicellular organisms, mutations can be subdivided into germline mutations and somatic mutations. Germline mutations occur in the DNA of sex cells, or gametes, and are therefore potentially very serious. These mutations can be passed to the next generation. If the zygote contains the mutation, every cell in the resulting organism will have that mutation. If the mutation results in a disease phenotype, the mutation causes what is called a hereditary disease. Somatic mutations , which occur in somatic, or body, cells, cannot be passed to the next generation (offspring). Mutations present in a somatic cell of an organism will be present (by DNA replication and mitosis) in all descendants of that cell. If the mutation is present in a gene that is not used in that cell type, the mutation may have no effect. On the other hand, the mutation may lead to a serious medical condition such as cancer. The specialists studied two groups of larvae. Group L displayed all kinds of mutations while group D didn't. Which group of larvae had more germline mutations?
++++++++++++++++++++++++++++++++
The answer is:
Group L

input question: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis. Greg is a doctor with the city hospital. Today, he is seeing two patients, patient A and patient B. Patient A maintains a high-fat diet, but patient B does not maintain a high fat diet. Greg is advising the patients how lifestyle change can improve their health. Which patient would have narrower arteries, patient A or patient B????
output answer: patient A

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 other small alkanes are listed in the 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 boil and melt at higher temperatures. Scientists are studying two alkanes in a laboratory, Mophane and Tripane. Scientists are analyzing the various characteristics of these alkanes to be used in future scientific studies. They discover that Mophane has more carbon atoms than Tripane. This information will definitely be useful in the future! Which alkane is smaller?
----
Answer: Tripane

Q: A firm with high fixed costs requires a large number of customers in order to have a meaningful return on investment. This is where economies of scale become important. Since each firm has large initial costs, as the firm gains market share and increases its output the fixed cost (what they initially invested) is divided among a larger number of customers. Therefore, in industries with large initial investment requirements, average total cost declines as output increases over a much larger range of output levels. City D's mayor wants to invite more businesses in the city. Three firms, firm A, firm B, and firm C, took advantage of this opportunity. Firm A does not require large initial costs, but firm B and firm C require large initial costs. Firm B managed to increase its market share, but firm C failed to increase its market share. Which firm would not have meaningful return on investment if they don't get large number of customers, firm A or firm B?
A: firm B

[Q]: During late adulthood, the risk of developing diseases such as cardiovascular diseases and cancer continues to rise. Most people also have a decline in strength and stamina. Their senses may start failing, and their reflex time typically increases. Their immune system also doesn't work as well as it used to. As a result, common diseases like the flu may become more serious and even lead to death. The majority of late adults develop arthritis, and as many as one in four develop Alzheimer's disease. Margaret is a sophomore in high school who just started her Spring break. With a week off from school, her family is spending some time driving out of state to visit her grandma, Kathy, who has a cabin up in the snowy mountains. Margaret always enjoys spending time with her grandma because she has interesting stories and makes some of the best pie around. Also, they always go skiing when visiting the cabin so Margaret is excited for that. Who would be more likely to get lost on the mountain?
****
[A]:
Kathy
