Penyakit kaki gajah adalah sejenis penyakit yang disebabkan oleh cacing yang ditularkan oleh nyamuk. Nyamuk bertindak sebagai vektor atau perantara dalam penularan penyakit ini. Ketika nyamuk menggigit manusia yang terinfeksi cacing penyebab penyakit kaki gajah, nyamuk tersebut juga terinfeksi cacing tersebut. Kemudian, nyamuk yang terinfeksi dapat menularkan cacing ke manusia lain melalui gigitannya. Oleh karena itu, nyamuk menjadi penyebab utama penyebaran penyakit kaki gajah.

Metamorfosis tidak sempurna adalah suatu proses perkembangan hewan yang melibatkan tiga tahap yaitu telur, nimfa, dan dewasa. Pada metamorfosis tidak sempurna, nimfa memiliki bentuk yang mirip dengan dewasa, tetapi ukurannya lebih kecil dan tidak memiliki sayap. Kecoa termasuk dalam jenis hewan yang mengalami metamorfosis tidak sempurna, karena mereka melewati tahap-tahap tersebut.

Porifera or sponges do not have a circulatory system, so food is distributed by the cells called amebocytes. These cells are responsible for transporting nutrients and other essential substances throughout the sponge's body. They also play a role in waste removal and the production of skeletal elements. Therefore, option c, sel amubosit, is the correct answer as it accurately describes the mechanism by which food is circulated in Porifera.

Crustacea memiliki alat gerak yang terletak di ruas abdomen mereka, dan alat gerak ini berupa kaki. Jadi, jawaban yang benar adalah c. kaki.

Insects with two types of sucking mouthparts, complete metamorphosis, and are vectors of dengue fever belong to the order Diptera. Diptera is the order of insects that includes flies, mosquitoes, and gnats. These insects have specialized mouthparts for piercing and sucking, which allows them to feed on the blood of humans and animals. They undergo complete metamorphosis, meaning they have distinct larval, pupal, and adult stages. The ability to transmit diseases like dengue fever makes them important vectors for public health concerns.

Arthropoda is a phylum of animals that includes invertebrates and has a diverse body structure. Arthropods with three pairs of legs on their thorax are classified in the class Insecta. This class includes insects, which are characterized by their six legs and three body segments (head, thorax, and abdomen). Therefore, the correct answer is b. insecta.

Obelia memiliki ciri-ciri sebagai berikut: fase dominannya adalah polip, fase yang membentuk medusa disebut gonangium, dan fase medusa berenang bebas. Namun, Obelia tidak menghasilkan tunas pada fase medusanya.

The correct answer is c. 1 dan 2. Dalam pertanyaan ini, terdapat 3 jenis cacing pipih yang disebutkan: Fasciola Hepatica, Taenia Saginata, dan Taenia Solium. Dikatakan bahwa yang hidup pada sapi adalah cacing pipih nomor 1 dan 2. Oleh karena itu, jawaban yang benar adalah c. 1 dan 2.

Cacing tambang adalah jenis cacing parasit yang masuk ke dalam tubuh manusia dalam bentuk telur. Setelah telur tersebut tertelan, larva cacing tambang akan menembus dinding usus dan masuk ke dalam aliran darah. Dari sana, larva akan berpindah ke paru-paru melalui pembuluh darah dan saluran napas. Di paru-paru, larva akan tumbuh dan berkembang biak, kemudian bergerak ke saluran pernapasan atas dan ditelan kembali. Siklus hidup cacing tambang melalui paru-paru ini terjadi secara terus-menerus, menyebabkan gejala seperti batuk, sesak napas, dan kadang-kadang darah dalam dahak.

Planaria memiliki tubuh yang bersegmen, jadi jawaban a. tubuh bersegmen adalah salah. Planaria juga memiliki tubuh bersilia, memiliki daya regenerasi tinggi, dan bersifat hermafrodit.

The correct answer is b. bernapas dengan lapisan mantel. Bivalvia memiliki ciri-ciri seperti memiliki 2 cangkang setangkup, berkaki pipih yang dapat dijulurkan, dan cangkangnya memiliki lapisan mutiara. Namun, mereka bernapas melalui insang, bukan dengan lapisan mantel.

In the life cycle of a frog, the youngest stage is the tadpole stage, where the frog breathes through external gills or gill slits, which are located on the sides of its head. This is known as breathing with external gills. As the frog grows and develops, it undergoes metamorphosis and the gills are replaced by lungs, allowing the adult frog to breathe through its nostrils. Therefore, option d, "bernapas dengan insang luar" (breathing with external gills), is the correct answer.

Nematosit is the correct answer because it refers to the body part in Coelenterata that serves as a defense mechanism and also helps in paralyzing its enemies. Nematosit are specialized cells that contain a coiled thread-like structure called a cnidocyst, which is used to inject venom into prey or attackers. This allows Coelenterata to protect itself and immobilize its enemies for feeding or defense purposes. Tentakel is incorrect as it refers to the elongated flexible appendages used for capturing prey or sensing the environment. Mesoglea is incorrect as it refers to the jelly-like substance that fills the body cavity. Cakram kaki is incorrect as it does not have any relevance to the defense mechanism in Coelenterata.

In the life cycle of Aurelia, the stage with characteristics of free-swimming, having cilia, and not having tentacles is called planula.

Cnidaria, such as jellyfish and sea anemones, release toxins through their tentacles to weaken their enemies and prey. Tentacles are equipped with specialized structures called nematocysts, which contain venomous cells called nematocytes. When triggered, nematocysts shoot out tiny harpoon-like structures called cnidocysts that inject venom into the target. This venom can paralyze or kill the prey, making it easier for the Cnidaria to capture and consume it.

The correct answer is d. melepaskan diri dari rangkaian proglotid. The other options listed, a, b, and c, are all functions of the air sacs in birds. Air sacs help birds produce louder sounds, regulate body temperature, and control the density of their bodies while flying. However, releasing oneself from a chain of proglotid is not a function of air sacs.

The correct answer is a. udang. The description mentions that the animal has legs with multiple segments on every part of its body, and its body is divided into cephalothorax and abdomen. These characteristics are typical of a shrimp, which is an invertebrate animal with segmented legs and a body divided into two parts.

The correct answer is a. reptilia. Reptiles are ectothermic animals, meaning they rely on external sources of heat to regulate their body temperature. They also undergo ecdysis or molting, where they shed their outer layer of skin periodically as they grow. This process allows them to replace damaged or worn-out skin and maintain optimal functioning. Amphibians, mammals, and birds, on the other hand, are endothermic animals and do not undergo ecdysis.

Eating vegetables that grow in water and are not cooked properly can pose a high risk of infection with Ascaris lumbricoides, a type of roundworm.

The correct answer is d. ikan hiu dan kuda laut. Osteichthyes is a class of fish that includes bony fish. Sharks (ikan hiu) and seahorses (kuda laut) are both examples of bony fish, so they belong to the class Osteichthyes.
