    • Zigot - blastula - morula - gastrula - tubuh organisme

    • Zigot - morula - gastrula - blastula - tubuh organisme

    • Zigot - blastula - gastrula - morula - tubuh organisme

    Correct Answer
    A. Zigot - morula - blastula - gastrula - tubuh organisme
    Explanation
    The correct answer is "zigot - morula - blastula - gastrula - tubuh organisme". This is the correct sequence of developmental stages in animal embryogenesis. The zygote is formed by the fusion of sperm and egg, which then undergoes cell division to form a solid ball of cells called the morula. The morula then undergoes further cell division and rearrangement to form a hollow ball of cells called the blastula. The blastula then undergoes gastrulation, where the cells rearrange and differentiate to form the three germ layers (ectoderm, mesoderm, and endoderm) and the body plan of the organism is established.

    Pernapasan pada Platyhelminthes berlangsung dengan cara ...

    • Melalui sistem pernapasan sederhana

    • Menggunakan trakea

    • Melalui faring dan kerongkongan

    • Difusi melalui permukaan tubuh

    Correct Answer
    A. Difusi melalui permukaan tubuh
    Explanation
    The correct answer is "difusi melalui permukaan tubuh" (diffusion through the body surface). Platyhelminthes, also known as flatworms, have a simple body structure with a thin and flat body shape. They lack specialized respiratory organs such as gills or lungs. Instead, they rely on the process of diffusion to exchange gases with their environment. Oxygen from the surrounding water or air diffuses across their thin body surface and enters their cells, while carbon dioxide produced by cellular respiration diffuses out of their body. This method of respiration is efficient for small and flat organisms like Platyhelminthes.

    • Koanosit

    • Sel skleroblas

    • Arkeosit

    • Sel ameboid

    Correct Answer
    A. Sel ameboid
    Explanation
    Porifera, or sponges, do not have a circulatory system. Instead, food is distributed through the body by amoeboid cells. These cells are capable of changing their shape and moving around, allowing them to transport nutrients to different parts of the sponge's body. This method of food distribution is necessary for sponges since they lack specialized organs or systems for digestion and circulation.

    • Koanosit

    • Pinakosit

    • Sel skleroblas

    • Sel ameboid

    Correct Answer
    A. Pinakosit
    Explanation
    Porifera dapat menanggapi rangsang dari luar tubuhnya karena memiliki bagian pinakosit. Pinakosit adalah jenis sel yang terdapat pada tubuh Porifera dan berfungsi sebagai sel pelindung serta berperan dalam proses penangkapan dan pencernaan partikel makanan. Sel-sel pinakosit ini juga berperan dalam merespons rangsang dari luar tubuh, seperti cahaya atau sentuhan. Dengan adanya sel pinakosit, Porifera dapat merespons dan berinteraksi dengan lingkungannya.

    • Triploblastik selomata

    • Hidup sebagai parasit

    • Telur berkembang menjadi larva

    Correct Answer
    A. Tubuh pipih dorsoventral
    Explanation
    The correct answer is "tubuh pipih dorsoventral." This means that the general characteristic of Platyhelminthes is having a flat body that is compressed from top to bottom. This adaptation allows them to live in various habitats, including aquatic environments and as parasites in other organisms. The flat shape also helps them to absorb nutrients efficiently through their body surface.

    • Medusa - skifistoma - stobila - efira - zigot - planula

    Correct Answer
    A. Zigot - planula - skifistoma - strobila - efira - medusa
    Explanation
    The correct order of development for Aurelia is zigot (fertilized egg) - planula (larva) - skifistoma (polyp) - strobila (polyp with reproductive structures) - efira (young medusa) - medusa (adult jellyfish). This sequence represents the typical life cycle of Aurelia, starting from the fertilized egg, progressing through different larval and polyp stages, and finally reaching the adult medusa stage.

    • Zat tanduk

    • Zat kutikula

    • Zat kitin

    • Lapisan lendir

    Correct Answer
    A. Zat kutikula
    Explanation
    The correct answer is "zat kutikula". Parasitic worms have a protective outer covering called cuticle, which helps them avoid being digested by their host. The cuticle provides physical resistance and prevents the worm from being broken down by the host's digestive enzymes. This adaptation allows the worm to survive and continue its parasitic lifestyle.
