黃金的化學符號是 Au,源自拉丁詞「aurum」,意思是「閃耀的黎明」。黃金是一種珍貴的金屬,以其黃色光澤而聞名,在有記載的歷史中一直用於鑄幣、珠寶和其他藝術品。阿爾伯特·愛因斯坦因其開創性的相對論而聞名,這些理論徹底改變了我們對空間、時間和能量的理解。他著名的 E=mc² 方程式影響了從核能到全球定位系統技術的一切事物。鐙骨是人體最小的骨頭,位於中耳。它約2-3毫米長,在將聲波振動傳遞到內耳以進行聽覺方面起著關鍵作用。艾薩克·牛頓在17世紀發現了萬有引力定律,解釋了物體如何根據質量和距離相互吸引。這一定律為經典力學奠定了基礎,並有助於預測行星運動。氮氣約佔地球大氣層的78%,是我們呼吸的主要氣體。它對生命至關重要,形成蛋白質和DNA,並通過細菌的固氮等過程在環境中循環。鐵的元素週期表符號是Fe,來自拉丁文「ferrum」。鐵是一種重要的金屬,用於建築、工具,甚至作為血紅蛋白的一部分存在於我們的血液中,負責將氧氣輸送到全身。金星因其相似的大小、質量和組成而被稱為地球的雙胞胎。然而,它濃厚的大氣層會 trapping 熱量,使其成為太陽系中最熱的行星,表面溫度超過460°C。粒線體被稱為細胞的發電廠,因為它們通過細胞呼吸產生ATP形式的能量。它們擁有自己的DNA,並被認為是從古老的細菌演變而來的。愛德華·詹納在1796年使用牛痘材料開發了第一種天花疫苗。這項突破為現代免疫學奠定了基礎,並通過預防傳染病挽救了無數生命。元素週期表上的「O」代表氧,氧氣對呼吸和燃燒至關重要。它約占地球大氣層的21%,是水和有機分子中的關鍵組成部分。查爾斯·達爾文於1859年在其著作《物種起源》中提出了自然選擇的進化論。它解釋了物種如何通過提高生存和繁殖的變異來隨時間適應。土星以其廣泛的環系統而聞名,該系統由冰、岩石和塵埃顆粒組成。這些環最早由伽利略於1610年觀測到,據信是彗星或衛星的殘餘物。水的化學符號是H2O,由兩個氫原子和一個氧原子組成。水對所有已知生命形式都至關重要,覆蓋地球約71%的表面並調節氣候。皮膚是人體最大的器官,成人覆蓋約2平方公尺。它能抵抗病原體、調節體溫,並包含觸覺、疼痛和熱的感覺受器。在標準大氣壓下,水在100°C沸騰,從液體變為氣體。這個溫度被用作攝氏溫標的參考點,該溫標是根據水的冰點和沸點定義的。葉綠素是綠色的,是植物中吸收陽光進行光合作用的色素。它賦予葉子顏色,對於將二氧化碳和水轉化為葡萄糖和氧氣至關重要。我們太陽系有8顆行星:水星、金星、地球、火星、木星、土星、天王星和海王星。冥王星於2006年被國際天文聯合會重新分類為矮行星。鑽石是地球上最堅硬的天然物質,在莫氏硬度表上得分為10。它在高壓和高溫下在地幔中形成,用於珠寶和工業切割工具。當皮膚暴露在陽光中的UVB射線下時,會產生維生素D。它有助於吸收鈣以促進骨骼健康,並支持免疫系統,預防佝僂病等疾病。顱骨是保護大腦並形成頭部的骨骼結構。它由22塊骨骼組成,並容納眼睛和耳朵等感覺器官,對於保護和功能至關重要。植物在光合作用中吸收二氧化碳以產生葡萄糖並釋放氧氣。這個過程對於碳循環至關重要,並通過減少大氣中的二氧化碳水平來幫助減緩氣候變化。安培(A)是電流的單位,測量電荷的流動。它以安德烈-瑪麗·安培的名字命名,在電學中是基礎的,例如在電路和電池中。鴿子是和平的象徵,經常被描繪成銜著橄欖枝,源自聖經故事,如諾亞方舟。在現代,它被用於反戰運動和國際符號。純水的pH值為7,表示在pH尺度上為中性,pH尺度測量酸度或鹼度。值低於7是酸性,高於7是鹼性,這對生物化學反應至關重要。蝙蝠是唯一能夠持續飛行的哺乳動物,牠們的翅膀是由皮膚拉伸在細長的指骨上形成的。牠們在授粉、種子傳播和昆蟲控制中扮演關鍵角色。重力是使行星圍繞太陽運行的力,如牛頓萬有引力定律所描述。它平衡了行星的慣性,創造了穩定的橢圓軌道。天文學是研究恆星、行星和宇宙的學科。它利用望遠鏡和衛星觀察天體,幫助我們了解黑洞和星系等現象。食鹽是氯化鈉(NaCl),一種對神經功能和體液平衡至關重要的離子化合物。它從礦床中開採或從海水中蒸發而來。水星是離太陽最近的行星,平均距離為5800萬公里。它具有極端的溫度波動和類似月球的佈滿隕石坑的表面。真空中的光速約為每秒30萬公里,是物理學中的一個常數。它是宇宙中的最大速度,是愛因斯坦相對論的核心。每天一蘋果,醫生遠離我,這句諺語強調了蘋果的健康益處,例如纖維和維生素。蘋果富含抗氧化劑,已被種植了4000多年。氫的原子序數為1,這意味著它的原子核中只有一個質子。它是宇宙中最輕、最豐富的元素,通過核聚變為恆星提供燃料。太平洋是最大的海洋,覆蓋了地球表面約30%的面積。它包含地球上最深的地方——馬里亞納海溝,並影響全球天氣模式。木星是最大的行星,直徑超過地球的11倍,質量是所有其他行星總和的兩倍。它是一個氣態巨行星,有一個持續了幾個世紀的大紅斑風暴。矽約佔地殼的28%,存在於岩石、沙子和石英等礦物中。它是半導體、玻璃和陶瓷的關鍵,推動著現代科技。遊隼以超過240英里/小時(386公里/小時)的速度俯衝,使其成為最快的動物。它的適應性包括流線型的身體和敏銳的視力,用於空中狩獵。碳的原子序數是6,表示它有六個質子。它是有機化學的基礎,形成多種化合物,如鑽石、石墨和維持生命的分子。外核由熔融的鐵和鎳組成,是液態的,並通過對流產生地球的磁場。它約1400英里厚,極其高溫。胰島素由胰腺產生,通過促進細胞吸收來降低血糖。糖尿病是胰島素缺乏或抵抗導致的,影響能量代謝。古生物學研究化石以了解古代生命、演化和生態系統。它利用骨骼和印記等證據來重建史前世界,從恐龍到早期人類。You scored 0 out of 40You scored 1 out of 40You scored 2 out of 40You scored 3 out of 40You scored 4 out of 40You scored 5 out of 40You scored 6 out of 40You scored 7 out of 40You scored 8 out of 40You scored 9 out of 40You scored 10 out of 40You scored 11 out of 40You scored 12 out of 40You scored 13 out of 40You scored 14 out of 40You scored 15 out of 40You scored 16 out of 40You scored 17 out of 40You scored 18 out of 40You scored 19 out of 40You scored 20 out of 40You scored 21 out of 40You scored 22 out of 40You scored 23 out of 40You scored 24 out of 40You scored 25 out of 40You scored 26 out of 40You scored 27 out of 40You scored 28 out of 40You scored 29 out of 40You scored 30 out of 40You scored 31 out of 40You scored 32 out of 40You scored 33 out of 40You scored 34 out of 40You scored 35 out of 40You scored 36 out of 40You scored 37 out of 40You scored 38 out of 40You scored 39 out of 40You scored 40 out of 40
