Biologi - Animalia (Kelas X)

Based on the observation provided, the animal in question has characteristics of living both in water and on land, possessing a vocal sac, and being a poikilothermic organism. These characteristics are commonly found in amphibians, which are known for their ability to live in both aquatic and terrestrial environments, have vocal sacs for producing sounds, and are cold-blooded. Therefore, the correct answer is Amphibia.

Demospongiae is the correct answer because it refers to a class of sponges that includes the sponges that can be used as bath sponges. This class is known for having a variety of shapes, sizes, and colors, and they are commonly found in marine environments. Demospongiae sponges are composed of a flexible, fibrous skeleton made of spongin, which gives them their soft and absorbent qualities that make them suitable for use as bath sponges.

Hirudo medicinalis, also known as the medicinal leech, is a beneficial animal in the field of healthcare. It is used to suck blood during infections. The saliva of the leech contains various bioactive substances that have medicinal properties, such as anticoagulants and anti-inflammatory compounds. These substances can help improve blood circulation and reduce swelling in infected areas. Additionally, the leech's saliva has been found to have analgesic properties, providing pain relief to patients. Therefore, the use of Hirudo medicinalis in medical procedures can aid in the treatment and recovery of certain infections.

Anak-anak banyak yang mengalami infeksi cacing perut (Ascaris lumbricoides) karena penularan cacing ini adalah dengan cara telur yang terbawa makanan atau minuman. This means that the main mode of transmission for Ascaris lumbricoides is through the ingestion of food or water contaminated with the eggs of the parasite.

Wucheria brancofti is a parasitic worm that causes a condition known as elephantiasis, which is characterized by the swelling and enlargement of limbs, particularly the legs. This condition is commonly referred to as "kaki gajah" in Indonesian, hence the correct answer choice is Wucheria brancofti. Fasciola hepatica is a liver fluke that causes fascioliasis, Chlorosinesis is not a recognized term or organism, Taenia volium is a tapeworm that causes taeniasis, and Ascaris lumbricoides is a roundworm that causes ascariasis.

Mammals are characterized by having mammary glands, which produce milk to nourish their young. This is a unique feature of mammals that sets them apart from other animal classes. While other characteristics listed, such as having hair, giving birth to live young, and having warm blood, are also common among mammals, it is the presence of mammary glands that specifically identifies an animal as a mammal.

Anggota Arthropoda yang memiliki rangka luar, tidak bersayap kepala menyatu dengan dada, dan bernapas dengan insang termasuk dalam kelas Crustacea.

The correct answer is Platypus. The question is asking for an example of a mammal that lays eggs and is also known as a transition between birds and mammals. The platypus fits this description as it is a unique mammal that lays eggs, has a duck-like bill, and possesses both mammalian and reptilian characteristics.

Cephalopoda is the correct answer because it is a group of Mollusca that have their locomotion organs located in their head region. Cephalopods, such as squid and octopus, have well-developed tentacles and arms that they use for movement and capturing prey. This characteristic distinguishes them from other groups of Mollusca, such as Amphineura, Bivalvia, Gastropoda, and Scaphopoda, which have different adaptations for locomotion.

The correct answer is "mengisap sari makanan dari usus" because Ascaris lumbricoides is a parasitic worm that lives in the intestines of humans. It obtains its nutrition by sucking the nutrients from the food that the host consumes in the intestines.

The correct answer is "mengedarkan sari makanan." Amebocytes in Porifera function to distribute and transport food particles throughout the sponge's body. They help in the digestion and absorption of nutrients by moving food particles to different cells within the sponge.

The correct answer is Gastropoda. Gastropoda is a class of mollusks that have a coiled shell, a muscular foot, and a head with tentacles. They are not considered invertebrates because they have a well-developed internal skeleton. The other options listed, Platyhelminthes, Annelida, Coelenterata, and Nemathelminthes, are all phyla of invertebrates that do not have a backbone.

Polychaeta is the correct answer because cacing palolo, or palolo worms, belong to this class. Polychaeta is a class of annelid worms that are characterized by having numerous bristle-like appendages called chaetae. Palolo worms are known for their unique reproductive behavior where they undergo mass spawning events, known as palolo rises, during specific times of the year. These worms are found in marine environments and are often used as a food source by humans and other animals.

Trematoda adalah kelompok hewan yang juga dikenal sebagai cacing isap. Mereka adalah parasit internal yang hidup di dalam tubuh inangnya dan memiliki struktur tubuh yang menyerupai cacing isap. Trematoda termasuk dalam filum Platyhelminthes, yang juga mencakup kelompok hewan seperti Cestoda (cacing pita) dan Turbellaria (cacing pipih). Rotifera dan Nemertea bukanlah kelompok hewan yang disebut sebagai cacing isap.

Octopus tidak memiliki cangkang karena mereka termasuk dalam kelompok Cephalopoda yang memiliki tubuh yang lebih lunak dan tidak memiliki cangkang pelindung seperti yang dimiliki oleh kebanyakan Mollusca. Mereka memiliki kemampuan untuk mengubah warna dan bentuk tubuh mereka serta memiliki sistem pertahanan yang berbeda seperti menyemburkan tinta untuk melindungi diri.

Lintah adalah contoh cacing yang tidak memiliki rambut atau seta.

Arthropoda adalah filum hewan yang memiliki ciri-ciri tubuh yang dilindungi oleh eksoskeleton luar yang keras dan terdiri dari segmen-segmen yang berulang. Kelas Heksapoda dalam filum Arthropoda terdiri dari serangga, yang memiliki enam kaki. Lalat rumah adalah salah satu contoh serangga yang termasuk dalam kelas Heksapoda karena memiliki enam kaki.

Pembelahan biner adalah proses reproduksi aseksual di mana organisme membelah menjadi dua bagian yang identik secara genetik. Pada planaria, pembelahan biner terjadi ketika tubuh organisme terbelah menjadi dua bagian yang sama ukurannya, dan setiap bagian tersebut akan tumbuh menjadi individu baru yang lengkap. Dengan demikian, pembelahan biner adalah cara reproduksi aseksual yang dilakukan oleh planaria.

Individu yang termasuk pada kelas Agnatha tidak memiliki rahang.

The correct answer is Isoptera because termites, or laron in Indonesian, have two pairs of thin wings of equal size and biting mouthparts, which are characteristics of insects in the order Isoptera.
