Question: 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 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. Will Gary's water bill be higher or lower than Jerry's?
Answer: higher

[Q]: Ocean acidification occurs when excess carbon dioxide in the atmosphere causes the oceans to become acidic. Burning fossil fuels has led to an increase in carbon dioxide in the atmosphere. This carbon dioxide is then absorbed by the oceans, which lowers the pH of the water. Ocean acidification can kill corals and shellfish. It may also cause marine organisms to reproduce less, which could harm other organisms in the food chain. As a result, there also may be fewer marine organisms for humans to consume. San Francisco and Baltimore both have large manufacturing and production industries and both border large oceans. San Francisco has been burning large amounts of fossil fuels recently to fuel their increased manufacturing and production of automobiles. Baltimore, however, has shifted to renewable resources recently, and as a result they have drastically decreased the amount of fossil fuels that are used to produce and manufacture steel. Which city, San Francisco or Baltimore, releases more carbon dioxide into the atmosphere?
****
[A]: San Francisco

input: Please answer the following: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe. Two brothers took a blood test. The doctor found out that Tim had hemophilia, while his brother Rick had normal blood cells and was healthy. Which brother had a hereditary disease?
++++++++++
output: Tim

Please answer this: A wood-decay fungus is any species of fungus that digests moist wood, causing it to rot. Some species of wood-decay fungi attack dead wood, such as brown rot, and some, such as Armillaria (honey fungus), are parasitic and colonize living trees. Excessive moisture above the fibre saturation point in wood is required for fungal colonization and proliferation.[1] Fungi that not only grow on wood but permeate its fibrous structure and actually cause decay, are called lignicolous fungi. In nature, this process causes the breakdown of complex molecules and leads to the return of nutrients to the soil.[2] Various lignicolous fungi consume wood in various ways; for example, some attack the carbohydrates in wood and some others decay lignin. The rate of decay of wooden materials in various climates can be estimated by empirical models.[3] The mycologist wanted to move to a rural area, to further his research, and found these two villages situated 10 miles from each other. The interesting fact about these villages was that while both villages had a forest nearby, one presented more signs of water saturation than the other, so that the rate of decay in wood was greater in Peak Forest. More fungi were present in Peak Forest. The Valley Forest was dryer, although the rain amounts were similar, partially because of a drainage system composed of ditches, that were dug by the locals. The rate of wood decay continued to increase in the Peak Forest, while being significantly reduced in the Valley Forest. Which forest will have more honey fungus?
++++++++
Answer: Peak Forest

Problem: Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn't matter whether the radiation comes from tanning lamps or the sun. Two friends had different lifestyles. Tom adopted a healthy lifestyle choice to prevent cancer, but Bill didn't. Bill was diagnosed with cancer a year later. Which of the two friends avoided carcinogens?

A: Tom

input: Please answer the following: As for the public health or food safety concern, organic foods are intended to be healthy, free of contaminations and free from agents that could cause human diseases. Organic milk is meant to have no chemical residues to consumers, and the restrictions on the use of antibiotics and chemicals in organic food production has the purpose to accomplish this goal. Although dairy cows in both organic and conventional farming practices can be exposed to pathogens, it has been shown that, because antibiotics are not permitted as a preventative measure in organic practices, there are far fewer antibiotic resistant pathogens on organic farms. This dramatically increases the efficacy of antibiotics when/if they are necessary. Two farms were growing food for several nearby cities. Vole farm grew organic produce and produced organic milk, while Anthill farm did not possess the USDA organic certification. Which farm produces more milk with no antibiotics?
++++++++++
output:
Vole
