Ayam banyak dipelihara oleh manusia untuk dikonsumsi daging dan telurnya. Daging ayam merupakan sumber protein yang penting dalam makanan manusia, sedangkan telur ayam juga merupakan sumber protein yang baik dan sering digunakan dalam berbagai resep makanan. Oleh karena itu, manusia memelihara ayam untuk memanfaatkan daging dan telur yang dihasilkannya.

Lidah berfungsi sebagai pengecap rasa di dalam tubuh manusia. Lidah memiliki ribuan papila yang mengandung reseptor rasa yang peka terhadap berbagai macam rasa seperti manis, asam, asin, pahit, dan umami. Ketika makanan atau minuman masuk ke mulut, lidah akan merasakan rasa tersebut dan mengirimkan sinyal ke otak untuk diinterpretasikan. Oleh karena itu, lidah merupakan organ yang penting dalam proses mencicipi dan menikmati makanan.

The correct answer is "Cakar yang tajam." The macan is a carnivorous animal that is known for its sharp claws, which it uses for hunting and capturing prey. These sharp claws enable the macan to grip and hold onto its prey firmly, making it an effective predator.

Jatuhnya benang sari ke putik dinamakan penyerbukan. Penyerbukan adalah proses transfer serbuk sari dari benang sari ke putik pada bunga. Ini adalah langkah penting dalam reproduksi tumbuhan berbunga, di mana serbuk sari yang mengandung sel-sel sperma dari bunga jantan ditransfer ke putik bunga betina untuk membuahi sel telur dan membentuk biji.

Burung merpati termasuk hewan pemakan biji karena mereka biasanya memakan biji-bijian sebagai makanan utama mereka. Biji-bijian seperti biji bunga matahari, jagung, dan kacang-kacangan sering menjadi bagian dari diet burung merpati. Mereka memiliki paruh yang kuat dan cocok untuk memecahkan kulit biji dan mengkonsumsi isinya. Selain itu, burung merpati juga dapat memakan makanan tambahan seperti dedaunan, buah-buahan, dan serangga, tetapi biji-bijian tetap menjadi makanan utama mereka.

The correct answer is "Rangka tengkorak" because the skull is the bone structure that protects the brain. The skull acts as a protective casing, surrounding and enclosing the brain, thus providing it with physical protection from injury or damage.

The given options categorize animals based on their diet, including herbivores, carnivores, and omnivores. However, "ovipar" does not refer to a specific type of diet but rather to animals that lay eggs. Therefore, the correct answer is "ovipar" as it does not belong to the grouping based on food habits.

Carnivorous animals have sharp teeth to be able to chew and consume meat. These sharp teeth are specifically designed for tearing and ripping apart flesh, allowing them to effectively feed on their prey.

The correct answer is "Telur – ulat – kepompong - kupu-kupu" because it follows the natural life cycle of a butterfly. The butterfly starts as an egg (telur), then hatches into a caterpillar (ulat), which later forms a chrysalis or cocoon (kepompong). Inside the cocoon, the caterpillar undergoes metamorphosis and transforms into a butterfly (kupu-kupu).

The correct answer is "Klorofil" because chlorophyll is the pigment responsible for the green color in leaves. It plays a crucial role in photosynthesis, the process by which plants convert sunlight into energy. Chlorophyll absorbs light energy from the sun and uses it to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells, specifically in the chlorophyll molecules. Without chlorophyll, leaves would not be able to capture sunlight effectively and carry out photosynthesis, resulting in a lack of green color.

Biji adalah bagian tumbuhan yang merupakan bakal dari tumbuhan baru. Biji berisi embrio yang dapat tumbuh menjadi tumbuhan baru ketika ditanam atau jatuh ke tanah yang sesuai. Biji juga mengandung cadangan makanan yang diperlukan oleh embrio untuk tumbuh dan berkembang.

The correct answer is Kelinci, marmut dan rusa. These animals, namely kelinci (rabbit), marmut (guinea pig), and rusa (deer), are all herbivores. Herbivores are animals that primarily feed on plants and do not consume meat.

The given question is asking for a bone disease or disorder, and the options provided are Tifus, Folio, Rakitis, and Osteoporosis. The correct answer is Tifus because it is not a bone disease or disorder. Tifus is a bacterial infection caused by the bacteria Salmonella typhi and is characterized by symptoms such as high fever, headache, and abdominal pain. It primarily affects the gastrointestinal system and does not directly affect the bones.

Tebu (sugar cane) is the correct answer because it does not have leaves with finger-like veins. The other three plants mentioned (pepaya, ketela, jarak) have leaves with finger-like veins, which is a characteristic of plants with netted venation.

The correct answer is "Omnivora" because tikus, bebek, and ayam are all animals that have a diet consisting of both plants and other animals. They have the ability to consume and digest both plant matter and meat, making them omnivores.

Stomata are small openings on the surface of leaves that allow for gas exchange in plants. They regulate the intake of carbon dioxide for photosynthesis and the release of oxygen and water vapor. Stomata also play a crucial role in controlling water loss from the plant through transpiration. Therefore, stomata are the correct answer as they are the respiratory organs in plants found on the leaves.

The given options describe the functions of the skeletal system in the human body. The skeletal system provides support and protection to important organs, serves as an attachment point for muscles and tissues, and allows for movement in the body. However, the function of "sebagai alat peraba tubuh" (as a body touch sensor) is not a recognized function of the skeletal system. Therefore, it is the correct answer.

The given options are all examples of animals that undergo complete metamorphosis, except for the cockroach. Cockroaches undergo incomplete metamorphosis, where they hatch from eggs as nymphs and gradually develop into adults without undergoing a dramatic change in body structure. On the other hand, flies, frogs, and butterflies all go through distinct stages of metamorphosis, including larva, pupa, and adult stages, with significant changes in their body structure and behavior.

Kekurangan vitamin D dan sinar ultraviolet dapat menyebabkan rakhitis karena vitamin D berperan penting dalam penyerapan kalsium dan fosfor oleh tubuh. Kekurangan vitamin D mengakibatkan penyerapan kalsium dan fosfor yang tidak efisien, sehingga dapat mengganggu pertumbuhan tulang yang normal. Sinar ultraviolet juga diperlukan untuk merangsang produksi vitamin D di dalam tubuh. Jadi, kekurangan vitamin D dan sinar ultraviolet dapat menyebabkan pertumbuhan tulang yang tidak wajar dan menjadi faktor penyebab rakhitis.

The correct answer is "Manis" because the phrase "ujung lidah sangat peka terhadap rasa" translates to "the tip of the tongue is very sensitive to taste." This suggests that the question is asking about which taste sensation is detected by the tip of the tongue, and the taste sensation associated with sweetness is "manis."

The question asks for the part that is not a part of a flower. The options provided are "Akar bunga" (flower root), "Tangkai bunga" (flower stem), "Kelopak bunga" (flower petals), and "Putik" (pistil). Among these options, "Akar bunga" is the correct answer because it is not a part of a flower. The root of a plant is responsible for absorbing water and nutrients from the soil, but it is not directly involved in the reproductive process of a flower.

Akar tumbuhan memiliki beberapa fungsi penting, termasuk menyerap air dan zat hara dari tanah, memperkokoh tumbuhan dengan menahan dan menopangnya, serta menjadi alat pernapasan melalui proses pernapasan aerobik. Namun, akar tumbuhan tidak dapat menyerap cahaya matahari karena fungsi ini dilakukan oleh daun tumbuhan melalui proses fotosintesis. Oleh karena itu, pilihan "Menyerap cahaya matahari" adalah pengecualian dalam daftar fungsi akar tumbuhan.

The correct answer is "Daur Hidup Hewan". This is because the question is asking for the sequence of events from the birth of an animal until it reproduces. "Daur Hidup Hewan" refers to the life cycle of an animal, which includes various stages such as birth, growth, reproduction, and death. Therefore, it encompasses the entire process from birth to reproduction, making it the most suitable answer.

The correct answer is "Telur – nimfa – kecoa" because it follows the correct sequence of the life cycle of a cockroach. The life cycle starts with eggs (telur), which hatch into nymphs (nimfa). The nymphs then go through several molting stages before reaching adulthood and becoming cockroaches (kecoa).

The given correct answer states that the incorrect characteristic of incomplete metamorphosis is the sequence of metamorphosis being egg → young animal → adult animal. In incomplete metamorphosis, the correct sequence is egg → nymph → adult. This explanation highlights the correct sequence of incomplete metamorphosis and identifies the incorrect option among the given choices.
