Question: Southampton has been used for military embarkation, including during 18th-century wars with the French, the Crimean war, and the Boer War. Southampton was designated No. 1 Military Embarkation port during the Great War and became a major centre for treating the returning wounded and POWs. It was also central to the preparations for the Invasion of Europe in 1944.
Try to answer this question if possible: What did the military use Southampton for during wars in the 18th century?
Answer: embarkation
Question: Many pesticides can be grouped into chemical families. Prominent insecticide families include organochlorines, organophosphates, and carbamates. Organochlorine hydrocarbons (e.g., DDT) could be separated into dichlorodiphenylethanes, cyclodiene compounds, and other related compounds. They operate by disrupting the sodium/potassium balance of the nerve fiber, forcing the nerve to transmit continuously. Their toxicities vary greatly, but they have been phased out because of their persistence and potential to bioaccumulate.:239240 Organophosphate and carbamates largely replaced organochlorines. Both operate through inhibiting the enzyme acetylcholinesterase, allowing acetylcholine to transfer nerve impulses indefinitely and causing a variety of symptoms such as weakness or paralysis. Organophosphates are quite toxic to vertebrates, and have in some cases been replaced by less toxic carbamates.:136137 Thiocarbamate and dithiocarbamates are subclasses of carbamates. Prominent families of herbicides include phenoxy and benzoic acid herbicides (e.g. 2,4-D), triazines (e.g., atrazine), ureas (e.g., diuron), and Chloroacetanilides (e.g., alachlor). Phenoxy compounds tend to selectively kill broad-leaf weeds rather than grasses. The phenoxy and benzoic acid herbicides function similar to plant growth hormones, and grow cells without normal cell division, crushing the plant's nutrient transport system.:300 Triazines interfere with photosynthesis.:335 Many commonly used pesticides are not included in these families, including glyphosate.
Try to answer this question if possible: What essential plan funtion is interrupted by triazines?
Answer: photosynthesis
Question: Compact fluorescent lamps (aka 'CFLs') use less power to supply the same amount of light as an incandescent lamp, however they contain mercury which is a dispose hazard. Due to the ability to reduce electric consumption, many organizations have undertaken measures to encourage the adoption of CFLs. Some electric utilities and local governments have subsidized CFLs or provided them free to customers as a means of reducing electric demand. For a given light output, CFLs use between one fifth and one quarter of the power of an equivalent incandescent lamp. One of the simplest and quickest ways for a household or business to become more energy efficient is to adopt CFLs as the main lamp source, as suggested by the Alliance for Climate Protection. Unlike incandescent lamps CFL's need a little time to 'warm up' and reach full brightness. Care should be taken when selecting CFL's because not all of them are suitable for dimming.
Try to answer this question if possible: What does CFL stand for?
Answer: Compact fluorescent lamps
Question: Pain is a distressing feeling often caused by intense or damaging stimuli, such as stubbing a toe, burning a finger, putting alcohol on a cut, and bumping the "funny bone". Because it is a complex, subjective phenomenon, defining pain has been a challenge. The International Association for the Study of Pain's widely used definition states: "Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage." In medical diagnosis, pain is a symptom.
Try to answer this question if possible: Why has defining pain been a challenge?
Answer:
complex, subjective phenomenon
