20/03/21 Good morning,it has been a long time🥸 I said before that I'm not in a good mood but now I am much happier than last week🥳 I got los of concern form a number of you !Thank you all💗 / This is the notes of biology 1-1 . But I haven’t added prokaryotes and eukaryotes yet🤧 I will finish as soon as possible! / Some people asked me if I went to see a psychologist in the end. “No.” Because I have no time🤣 It’s the friends around me and you who concerns about me that let me slowly come out of the low tide☺️ Thank you all !! / By the way...I received a gift from C2H4 @c2h4_study ✨ This thank may be come a bit late😅 But I really thank you very much !! Thank you for your blessing🥰 #112學測 #109會考 #studygram #study #studying #studyhard #math #고1 #고1공스타 #고1공스타그램 #勉強垢 #勉強垢さんと繋がりたい #勉強ノート #勉強記録 #學習 #studywithme #note #studynotes

世界有三域分立是事實 有研究話全球可能有一兆種生物，即係有99.999%生物仍然未被發現，但係科學家仍然可以將已知嘅生物分成三大「域」(domain)：「細菌」(Bacteria)、「古菌」(Archaea) 同「真核生物」(Eukaryotes)。 細菌結構簡單，基本上全部都係單細胞生物，冇細胞核，近乎無處不在，可能三十至四十億年前已經開始出現，好大機會係地球第一種生物黎架。 古菌都係單細胞生物，同樣冇細胞核，不過部份構造同細菌好唔同，有啲基因同代謝途徑甚至同真核生物更加相似，所以自成一域。 真核生物可以係單細胞生物，亦都包含所有多細胞生物，包括我地自己。真核生物同細菌古菌嘅決定性分別，在於真核生物有「真核」，即係細胞核 (true nucleus)，將基因資料包住，其他細胞構造亦都比較複雜。 「三域分立」係基本概念，係知識世界重要基石，就算有人刻意從教科書中抹去，我地照樣要將呢個概念傳承。 最近為主講一個動物學網上講堂系列做緊準備，個系列叫「我要進來了！動物界！」，唔使驚，唔會講細菌古菌，只講我地會生態旅遊去欣賞嘅動物界。歡迎去bio link睇睇更多資料啦，16/9正式開講! 「我要進來了！動物界！」講題一覽 第一講：鯊魚老過樹? 你見到的所有動物是如何煉成的 第二講：大笨象，唔打仗！非洲safari的大草原生態系統 第三講：鳥類才是真正的時間管理 KOL? 看懂動物界的啪啪啪行為! 第四講：攬炒生態學...? 生態旅遊在氣候變化時 #三域分立 #動物真有趣 #hkig #hkiger #hkguy #hkboy #travelgram #instatravel #travel #traveler #backpacker #backpacking #picoftheday #scenic #nature #letsgoout #lovetheworld

《Pulling & Mitochondria 粒線體》 When you pull yourself up, two major muscle groups work together. The latissimus dorsi, one of the largest muscles in your back, brings your upper arms closer to your troso, so your body rises to the bar. At the same time, the biceps muscles in your upper arms flex your elbows joints. To pull this iff, you need muscles with both strength and endurance. . . 👉Pull-ups take a lot of energy. As you workout, your heart pumps faster and you breathe more quickly, so you blood can carry more food and oxygen to your muscle cells. Mitochondria are tiny factories in your cells that turn food and oxygen into the fuel that powers your muscles. . 👉You inherit your mitochondria from your mother. . Mitochondria (singular, mitochondrion) are often called the powerhouses or energy factories of the cell. Their job is to make a steady supply of adenosine triphosphate (ATP), the cell’s main energy-carrying molecule. The process of making ATP using chemical energy from fuels such as sugars is called cellular respiration, and many of its steps happen inside the mitochondria. You may know that your body is made up of cells (trillions and trillions of them). You may also know that the reason you need to eat food—such as veggies—is so that you have the energy to do things like play sports, study, walk, and even breathe. But what exactly happens in your body to turn the food energy stored in broccoli into a form that your body can use? And how does energy end up stored in the broccoli to begin with, anyway? . Mitochondria are found inside of your cells, along with the cells of plants. They convert the energy stored in molecules from the broccoli (or other fuel molecules) into a form the cell can use.
