請問12.的lost to這樣那一句要怎麼翻?lost to是固定用法嗎(我有上網找但沒找到) 感謝~

第11.至15.題為題組 Coined in 2020, the term "revenge travel" stems from a feeling of wanting to break free from the monotonous life of lockdowns. After being confined in their homes for months due to the fear of the highly contagious disease and subsequent worldwide lockdowns, many people are 11. to travel even more before the pandemic. It appears that now, rather than feeling afraid and worried, people are just ready to get back at something: the year 2020 12. lockdowns. With this mindset, the tourism industry has greatly bounced back right after the COVID wave starts declining. Many people want to go somewhere so eagerly as they have felt imprisoned for so long. Take India for example. Many people still go traveling out of sheer frustration and the feeling of annoyance from August to October, generally considered the off-season for travel because of unfavorable weather conditions. 13. the freedom of traveling is being celebrated, everything comes at a price. That is, revenge travel has the potential to 14. months of lockdown, which breaks the chain of COVID-19 spread. As tens of thousands of people flock to popular scenic sites, it is crucial for everyone to observe social 15. the chance to be infected will be the last thing people expect. distancing and mask wearing. , Although these new norms can be quite disturbing, in the post pandemic era, people have to be prepared whereas 然而,而 to change their behaviors. (B) ambitious (C) reluctant (D) desperate

Experiment 7 Experiment 7 The partition of Organic acid between Water and Organic solvent Objectives Understand the partition of a solute between two immiscible solvents. Introduction A chemical analysis that is performed primarily with the aid of volumetric glassware (e.g., pipets, burets, volumetric flasks) is called a volumetric analysis. For a volumetric analysis procedure, a known quantity or a carefully measured amount of one substance reacts with a to-be-determined amount of another substance with the reaction occurring in aqueous solution. The volumes of all solutions are carefully measured with volumetric glassware. The known amount of the substance for an analysis is generally measured and available in two ways: 1. As a primary standard: An accurate mass (and thus, moles) of a solid substance is measured on a balance, dissolved in water, and then reacted with the substance being analyzed. 2. As a standard solution: A measured number of moles of substance is present in a measured volume of solution - a solution of known concentration, generally expressed as the molar concentration (or molarity) of the substance. A measured volume of the standard solution then reacts with the substance being analyzed. The reaction of the known substance with the substance to be analyzed, occurring in aqueous solution, is generally conducted by a titration procedure. The titration procedure required a buret to dispense a liquid, called the titrant, into a flask containing the analyte. A reaction is complete when stoichiometric amounts of the reacting substances are combined. In a titration this is the stoichiometric point. In this experiment the stoichiometric point for the acid-base titration is detected using a phenolphthalein indicator. Phenolphthalein is colorless in an acidic solution but pink in a basic solution. The point in the titration at which the phenolphthalein changes color is called the endpoint of the indicator. Indicators are selected so that the stoichiometric point in the titration coincides (at approximately the same pH) with the endpoint of the indicator.

6.2 細胞呼吸:有氧狀態獲取的食物能量 我們通常使用呼吸 (respiration)一詞來表示呼吸動作 (breathing)。雖然在生物體層次 上呼吸不應該跟細胞呼吸(cellular respiration)混淆,不過這兩個過程是相當有關聯性的 (圖6.3)。細胞呼吸需要跟環境周邊交換兩種氣體,細胞以氣體中的氧分子形式吸入,而 以氣體中的二氧化碳(CO2)形式讓廢物離開。呼吸動作(respiration 或breathing)造成你的 血液與外面的空氣交換相同氣體,氧氣存在於你吸入的空氣中,擴散越過肺臟內襯並流 你的血流中,血流中的二氧化碳會擴散到你的肺部深處,並在你呼氣的同時離開。你呼出的 每一個二氧化碳分子最初都是在你身體細胞內粒線體中形成的。 就像汽車上的內燃器一樣,使用氧氣(藉由氣體吸入)去分解汽油,一個細胞也 需要氧氣分解自身的能源。細胞呼吸——像一個生命模式的內燃器,是一個從食物 中的化學能量轉變成 ATP 能量的主要方式。細胞呼吸是一個有氧 (aerobic) 反應 換一個說法則是細胞呼吸需要氧氣。把這些都組合在一起,我們現在可以為細胞呼 吸 (cellular respiration) 下一個定義:即在有氧的情況下,從有機分子獲得化學機 量。☑ 你與跑車有 個共同點:你們 都需要一個進氣系 統使燃燒燃料更 有效率。 ☑ 檢查點 在生物體與細胞層次上, 呼吸包含吸入氣體 並排出氣體 。 。 :: 圖 6.3 呼吸 (breathing) 與細胞呼吸的相關性。當你吸氣 時,你會吸入氧氣。氧氣被輸送到細胞中,這裡的氧氣在細胞 呼吸中被利用。細胞呼吸的廢棄產物二氧化碳會從你的細胞擴 散到血液中,再循環至你的肺部後離開。 (CO2 (CO₂ 細胞呼吸 0₂ (CO2 肺 ST 肌肉細胞 6.2.1細胞呼吸的概述 生物學的一個重要主題就是所有的生物都取決 於能量和物質的轉變。我們在整個生命研究中看到 了這種轉化的例子,但很少像燃料(食品分子) 中 的能量轉化為細胞直接使用的形式般重要。通常 細胞使用的燃料分子是葡萄糖,即具有分子式為 CgH2O% 的單醣(monosaccharide) (參見圖 3.6) (較 使用其他有機分子來獲得能量)。以下平衡式簡述了 細胞呼吸期間葡萄糖的轉變: C6H12O6 +60 葡萄糖 氧氣 ↑ ↑ 能量 轉換 6CO,+6H+約32 ATP 二氧化碳 水 一序列的箭頭表示細胞呼吸由許多化學步驟 成。每個反應由一個特定的酶所催化——整個反應 徑全部超過二十多個反應。事實上,這些反應構、 了幾乎所有真核細胞——植物、真菌、原生生物和 物中發現的最重要的代謝路徑之一。這種路徑提供 了這些細胞維持生命功能所需的能量。 構成細胞呼吸的許多化學反應可以區分為三個 主要階段:糖解作用(glycolysis)、檸檬酸循環(Citric acid cycle) 和電子傳遞(electron transport)。 圖 6.4 是一個路線圖,可以幫助你按照呼吸作用 的三個階段進行,並看看每個階段在你的細胞中發
