植物透過光合作用吸收二氧化碳並釋放氧氣作為副產品,為我們提供了生存所需的空氣。這個過程在葉綠體中利用太陽能進行。金星自轉一圈需要243個地球日,但公轉太陽只需225天,因此它的一天比一年還要長。它濃密的大氣層導致了這種緩慢的自轉。粒線體透過細胞呼吸將營養物質轉化為ATP,是細胞的能量工廠。它們甚至擁有從您母親那裡繼承的DNA。胃分泌鹽酸(pH值1-2)來分解食物並殺死細菌。它足夠強大,可以隨著時間腐蝕一些金屬。重力將行星拉向太陽,平衡它們的向前運動以形成穩定的軌道。牛頓定律描述了這種普遍引力。氖氣在管中通電時會發出明亮的紅橙色光,創造出標誌性的霓虹燈。其他惰性氣體會產生不同的顏色。白血球(leukocytes)透過免疫反應偵測並摧毀病原體。它們對於對抗感染至關重要。每個作用力都有一個相等且反向的反作用力——就像你靠在牆上時,牆也會推回來。暴露於UVB射線的皮膚會合成維生素D,有助於吸收鈣質以維持骨骼健康。缺乏會導致佝僂病。電子在電子雲中以接近光速繞著原子核運行,決定了化學行為。它們帶負電。吸入氦氣會加速聲波在聲帶中的傳播,提高音調到尖銳的水平。它比空氣輕。腎臟過濾血液中的廢物和多餘液體形成尿液,調節平衡。它們每天處理大約180升血液。火成岩(如花崗岩或玄武岩)是由冷卻的岩漿或熔岩結晶而成。「火成」意指源於火。安培(amp)測量電流的流動速率——一安培等於每秒一庫侖。光合作用利用二氧化碳和水在葉綠體中將光能轉化為葡萄糖。方程式為 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂。DNA(去氧核醣核酸)以雙螺旋結構儲存遺傳指令。它存在於細胞核中。根據相對論,光在真空中以約299,792公里/秒的速度傳播,這是宇宙的速度極限。腎上腺素(epinephrine)會觸發戰鬥或逃跑反應,增加心率和能量。它由腎上腺釋放。平流層中的臭氧層吸收大部分紫外線輻射,保護生命免受DNA損傷。人類通過細胞呼吸排出二氧化碳,植物在白天利用它進行光合作用。伽利略通過比薩實驗證明,物體以相同的速率墜落,無論質量如何(忽略空氣阻力)。根部從土壤中吸收水分和礦物質,同時固定植物。根毛增加表面積。水銀的高沸點和受熱膨脹使其成為溫度計的理想材料,直到出現更安全的替代品。頻率越高的聲波產生越高的音高;頻率以赫茲 (Hz) 為單位測量。海洋生態系統擁有從浮游生物到鯨魚的各種物種,調節氣候和氧氣。當原子共享電子以實現穩定時,就會形成共價鍵,就像在 H₂O 分子中一樣。哈伯太空望遠鏡繞行於大氣層之上,自1990年以來捕捉遙遠星系的清晰影像。木星的大紅斑是一個比地球還大的反氣旋風暴,自17世紀以來就被觀測到。pH值為7表示中性;純水具有此值。低於7為酸性,高於7為鹼性。歐尼斯特·拉塞福的金箔實驗揭示了原子核,為核物理鋪平了道路。彈性位能儲存在壓縮的彈簧中,解開時釋放為動能。蜥蜴是外溫動物,吸收環境熱量來調節體溫。葉綠素吸收紅光和藍光進行光合作用,反射綠光。它存在於葉綠體中。細胞是生命的基本結構和功能單位,能夠進行新陳代謝和繁殖。凹面鏡向內彎曲,聚焦光線產生放大影像,例如在化妝鏡中。煤是由數百萬年前壓縮的植物物質形成,燃燒後產生電力。松果體分泌褪黑激素,根據光照調節睡眠-覺醒週期。中子是原子核中的中性粒子,有助於原子質量和穩定性。芮氏規模對地震震級進行對數量化;每一步代表10倍的能量。當酸和鹼反應形成水和離子鹽時,就會發生中和反應,平衡pH值。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
