"生物特征(biological characteristics)"指生物體在遺傳、生理、形态或行為等方面表現出的可觀察或可測量的固有屬性。這些特征是生物適應環境和維持生命的基礎,在不同學科中具有以下核心内涵:
遺傳特征
包括基因組成、DNA序列及遺傳變異等,決定物種的遺傳信息傳遞。例如人類血型、植物抗病基因等(來源:《遺傳學原理》)。
生理特征
涉及生物體的代謝活動、器官功能及生化反應機制,如體溫調節系統、光合作用能力等(來源:世界衛生組織生物醫學報告)。
形态特征
涵蓋生物體外部形态和内部結構,包括細胞構造、器官形态等解剖學特征,例如鳥類的喙形、植物的葉片脈絡(來源:《普通生物學》教材)。
行為特征
指物種特有的行為模式,包括遷徙習性、求偶儀式等先天性行為,以及學習能力等後天行為特征(來源:國家生物技術信息中心數據庫)。
這些特征的組合構成生物分類學依據,在醫學診斷、生态保護、進化生物學等領域具有重要應用價值。例如新冠病毒的刺突蛋白結構(形态特征)和傳播方式(行為特征)研究,為疫苗開發提供了關鍵依據(來源:《自然》期刊病原體專題)。
"Biological characteristics"(生物學特征)是指與生物體生命活動、結構或功能相關的固有屬性。以下從定義、分類和意義三個層面詳細解釋:
定義
指生物體在遺傳、生理、形态或行為層面表現出的可觀察或可測量的屬性,這些屬性由基因和環境共同作用形成,是區分不同物種或個體的基礎。
主要分類
科學意義
生物學特征是研究進化、生态適應、疾病診斷(如基因突變檢測)和生物分類的核心依據。例如,通過分析物種的形态特征可推斷其進化關系;醫學中利用血液生化特征輔助疾病篩查。
該術語常見于遺傳學、生态學、醫學等領域,強調生物體與生命規律的本質聯繫。
