    D. Biologi adalahilmu yang mempelajari semua mahluk yang hidup dimasa kini dan masa silam
    Explanation
    The correct answer states that biology is the study of all living beings in the present and in the past. This definition encompasses the study of all organisms that have ever existed, allowing researchers to understand the evolution and interconnectedness of life on Earth. By studying the past, biologists can gain insights into the origins and development of different species, as well as the environmental factors that have shaped their evolution over time.

      Lingkungan dan gen

    • E.

      Gen

    Correct Answer
    E. Gen
    Explanation
    The given answer, "gen," is correct because the statement suggests that individuals of the same species are never exactly the same for all traits, and this is due to differences in genes. Genes play a crucial role in determining the characteristics and traits of individuals, and variations in genes result in variations in traits among individuals of the same species. Therefore, the answer "gen" accurately explains the reason for the lack of identical individuals in a species.

    • A.

      Sumber energi primer

    • B.

      Jenis produsen

    • C.

      Produktivitas

    • D.

      Komponen abiotik

    • E.

      Komponen biotik

    Correct Answer
    A. Sumber energi primer
    Explanation
    The correct answer is "Sumber energi primer." The question asks for the component that does not indicate the biodiversity of an ecosystem. The other options, such as jenis produsen (type of producers), produktivitas (productivity), komponen abiotik (abiotic components), and komponen biotik (biotic components), all contribute to the diversity and functioning of an ecosystem. The primary energy source, on the other hand, does not directly indicate the diversity of species or components within an ecosystem.

      Tingkat filogenik

    • E.

      Tingkat ekologi

    Correct Answer
    B. Tingkat jenis
    Explanation
    Keanekaragaman hayati ditunjukkan dengan adanya variasi dalam satu spesies atau jenis mahluk hidup. Tingkat jenis mengacu pada variasi yang ada di antara berbagai jenis mahluk hidup. Jadi, tingkat jenis merupakan ukuran keanekaragaman hayati berdasarkan variasi di antara jenis-jenis mahluk hidup yang ada.

    • D.

      Mengetahui kekerabatan antar mahluk hidup

    • E.

      Mengetahui cara eksplotasi secara besar-besaran

    Correct Answer
    E. Mengetahui cara eksplotasi secara besar-besaran
    Explanation
    The other options mentioned in the question all relate to the benefits of studying biodiversity, such as understanding the relationships between different species, their characteristics, and their interdependence. However, the option "Mengetahui cara eksplotasi secara besar-besaran" (Knowing large-scale exploitation methods) does not align with the positive aspects of studying biodiversity. Instead, it suggests a negative consequence of studying biodiversity, as it implies the potential for exploiting or harming the environment on a large scale.

    • E.

      Variasi dan keanekaragaman

    Correct Answer
    B. Taksonomi
    Explanation
    Taksonomi adalah cabang biologi yang mengkaji teori dan praktek pengelompokan mahluk hidup berdasarkan karakteristik yang dimiliki oleh mereka. Dalam taksonomi, organisme dikelompokkan ke dalam takson berdasarkan kesamaan dan perbedaan dalam ciri-ciri fisik dan genetik mereka. Dengan menggunakan taksonomi, kita dapat mengklasifikasikan organisme ke dalam tingkatan takson seperti kerajaan, filum, kelas, ordo, famili, genus, dan spesies.

      Konvergensi

    • E.

      Adaptasi

    Correct Answer
    B. Buatan
    Explanation
    The correct answer is "buatan" because it refers to a classification system that is based on artificial similarities in the morphology, anatomy, physiology, and reproductive organs of organisms. This suggests that the classification system is man-made or created by humans rather than occurring naturally in the environment.

    • D.

      Spesies

    • E.

      Kelas

    Correct Answer
    C. Genus
    Explanation
    The scientific name for corn is zea mays, where "zea" refers to the genus of the plant. In taxonomy, the genus is a rank above species and below family. It groups together closely related species that share common characteristics and are more similar to each other than to species in other genera. Therefore, the correct answer is "genus" because it accurately represents the taxonomic classification of the plant name zea mays.

    • E.

      Suku sama bangsa berbeda

    Correct Answer
    B. Genus sama, spesies berbeda
    Explanation
    The given answer, "genus sama, spesies berbeda" (same genus, different species), is correct because it states that the tebu plant (Sacharum officinarum) and the gelagah plant (Sacharum spontaneum) belong to the same genus (Sacharum) but are different species. This means that they share some common characteristics but also have distinct differences, such as their physical appearance, habitat, or genetic makeup.

    • D.

      Kelas

    • E.

      Genus

    Correct Answer
    D. Kelas
    Explanation
    The correct answer is "kelas" (class). The question is asking for the lowest taxonomic level that includes both kacang (beans) and mangga (mango) in the same systematic position. The taxonomic hierarchy starts with kingdom, followed by phylum, class, order, family, genus, and species. Since both kacang and mangga belong to the same class, it is the lowest taxonomic level that includes both of them.

    Correct Answer
    C. 2 dan 3
    Explanation
    The correct answer is 2 and 3. This is because Musa textilis and Musa paradisiaca are both species of the Musa genus, which means they are closely related. Curcuma domestika and Felix domestica are not related to Musa, so they are not the closest relatives.

    Correct Answer
    C. Felidae
    Explanation

    Correct Answer
    D. Bioma hutan hujan tropis
    Explanation
    The correct answer is "bioma hutan hujan tropis." The explanation for this answer is that tropical rainforests are known to have high biodiversity due to their unique combination of warm temperatures, high rainfall, and stable climate conditions. These factors provide a favorable environment for a wide variety of plant and animal species to thrive, resulting in a high level of biological diversity.

Linnaeus's work laid the foundation for the classification and organization of living organisms based on their shared characteristics. His system is still widely used today in the field of biology and has greatly contributed to our understanding of the diversity of life on Earth.
