Scientist 2 explains that ice sublimes to water vapor and enters Europa&39;s atmosphere. If ultraviolet light then broke those water vapor molecules apart, which of the following gases would one most likely expect to find in Europa&39;s atmosphere as a result of this process？

A . Thread management inside the JVM process might be less effective than context switching between processes on the OS level. It is better to combine both these technologies to achieve full saturation of resources. B . Current CPUs are multicore units. So starting managed servers in the amount of physical cores and pinning them 1:1 to cores will always get the best performance. C . By a combination of prioritization of processes on the OS level and Work Manager in WLS, one  could tune the whole environment more precisely. D . Assigning more than one managed server to hardware will never bring better performance.  E . More instances means more connections to databases, so one could serve more concurrent calls on the database level. This is primarily why this approach will give better performance numbers.   F . Depending on the profile of the application, having more JVMs with smaller heaps will lead to more predictable response times than fewer JVMs with a large heap.

A . Amplification is prevented if global changes have only a local effect as opposed to systems in which global changes have a local effect B . Amplification is prevented if local changes have only a local effect as opposed to system inwhich localchange have a global effect C . Internet domain does not suffer from“The Amplification Principle”as BGP takes care of misbehaving advertisers D . None of the above

David Salt is an expert on plants at Purdue University in West Lafayette, Indiana. He is working with plants that store large amounts of metals. In recent years, scientists have shown interest in using such plants to clean up harmful waste materials. Professor Salt says such plants also could be used to improve people's diets or even to create foods that fight cancer. Humans need a number of metals in their diets, including iron and zinc. These metals are needed in very small amounts, however. That is why they are called micronutrients. The lack of micronutrients is blamed for health problems in many developing countries. Children and pregnant women are mostly affected. Recently, Mr. Salt announced that he has identified and copied the genes from a kind of plant that stores metals in its tissues. He says his study suggests it may be possible to develop plants that contain minerals needed for good health. For example, the metal selenium is a strong anti-cancer agent. Some wild plants store selenium naturally. Mr. Salt says foods to fight cancer might be created if genes from these plants could be moved into crop plants. Locoweed, which is a common plant in the western U.S., stores selenium. Professor Salt says it may be possible to create cancer-fighting foods from it. He and scientists from a company called Unicycle Therapies have copied the gene that causes locoweed to take up selenium from the soil. Many people take pills to add important minerals or vitamins to their diet. However, Mister Salt notes that most selenium products sold in health food stores are of little use. That is because the human body can only take in and use selenium if it is in the right chemical form. The scientist says his team would like to develop a vegetable crop high in selenium. He wants to create an anti-cancer product in the foods we already eat. According to Pro. Salt, plants that take up large amounts of metal in their tissues can be used to ______. A．clean polluted soil and cure disease like cancer B．clean up harmful waste materials in soil and improve people's diet C．produce large number of micronutrients such as iron and zinc D．create food with important minerals or vitamins
