However, they started to mix with European honeybees already living there and produced a new kind of "Africanized" honeybees that are better at setting up hiyes and at reproducing than European bees. Keeping Africanized bees poses a challenge to beekeepers. Generally, beekeepers keep their bees in 11. wooden boxes, or hives. s.

And they may need to wear heavier beekeeping suits even in hot, 14. weather. Beekeepers may also collect less honey from Africanized bee hives. European bees form search parties and work together to collect flower nectar from which honey is made, while Africanized bees usually work alone in search of flowers. Therefore, less nectar is brought back to Africanized bee hives. Africanized bees also spend less time storing honey but more time caring for young bees. That may be because they 15. in a tropical climate where not much honey is needed for food during the winter. (C) starved AB 11.

想請教A選項染色體套數跟DNA量之間有什麼關係(一直以為是分開看ㄉ)🙇🏻‍♀️🙇🏻‍♀️🧬

52.~54. 題為題組 [無合成分裂〕 自從 1835 年德國植物學家馮莫爾(Hugo von Mohl)在綠藻的研究中發現細胞分裂以來, 細胞的分裂已被廣泛研究。目前已知的生物細胞分裂包含有絲分裂、減數分裂與無絲分裂,在 進入分裂期之前都須經過遺傳物質(DNA)的複製,確保新生成的子細胞具備母細胞的遺傳訊 息。 翔於天際 2 然而在 2022 年 4 月,國際期刊《自然〉刊登了一篇由臺灣中研院研究團隊發表的論文, 提到脊椎動物斑馬魚的表皮細胞,可在未經 DNA 複製的狀態下進行細胞分裂產生新細胞。由 於沒有經過 DNA複製階段,新生成的子細胞皆不具備完整的母細胞 DNA。此一特殊的細胞分 裂被研究團隊稱為「無合成分裂」,其產生的子細胞型態較小、較扁,且僅發生在斑馬魚體表 最表面一層的表皮細胞;再往內一層的表皮細胞可以進行正常的有絲分裂。這個現象讓研究人 員十分納悶。 ( 經過對斑馬魚生活史的了解,研究人員認為在斑馬魚幼魚早期生長階段,體長變化十分快 速,需要更多的表皮細胞覆蓋身體表面以提供保護,進行無合成分裂可快速增加表皮細胞數 量。目前已知,連續進行兩次無合成分裂,可提升表皮細胞數量達6成的體表覆蓋率。相較 於一般有絲分裂,可以在身體資源有限的早期發育階段,更快速、更有效率地增加表皮細胞數 量。請根據本文回答下列問題。 52. 有關本文的敘述,下列哪些正確?(應選2項) 斑馬魚可利用無合成分裂完成無性生殖 \(B)表皮細胞的覆蓋速度提升,有助於體型的增長 (1) 無合成分裂是斑馬魚增加表皮細胞的唯一方法 (D)斑馬魚的表皮細胞也會進行有絲分裂 (每個染色體完整的細胞僅能進行一次無合成分裂
