Biologi Kelas 12

Biologi adalah ilmu alam yang mempelajari kehidupan, dan organisme hidup, termasuk struktur, fungsi, pertumbuhan, evolusi, persebaran, dan taksonominya.[1] Ilmu biologi modern sangat luas, dan eklektik, serta terdiri dari berbagai macam cabang, dan subdisiplin. Namun, meskipun lingkupnya luas, terdapat beberapa konsep umum yang mengatur semua penelitian, sehingga menyatukannya dalam satu bidang. Biologi umumnya mengakui sel sebagai satuan dasar kehidupan, gen sebagai satuan dasar pewarisan, dan evolusi sebagai mekanisme yang mendorong terciptanya spesies baru. Selain itu, organisme diyakini bertahan dengan mengonsumsi, dan mengubah energi serta dengan meregulasi keadaan dalamnya agar tetap stabil, dan vital.
