The correct answer is 2 because the image shows a picture of a knee joint, which is a hinge joint. The knee joint allows for flexion and extension of the leg, making it a type of synovial joint. The other options, such as a ball and socket joint (option 1), pivot joint (option 3), and gliding joint (option 4), do not accurately describe the joint shown in the image.

The correct answer is "Tulang punggung, tulang leher, tulang pinggang" because these are the bones that make up the spinal column or backbone. The spinal column is divided into different sections, including the cervical (neck) vertebrae, the thoracic (upper back) vertebrae, and the lumbar (lower back) vertebrae. Therefore, the bones mentioned in this answer choice are the ones that belong to the group of spinal bones.

The correct answer is "Daun telinga dan hidung". This is because the earlobe (daun telinga) and the tip of the nose (hidung) are both composed of cartilage. Cartilage is a flexible connective tissue that provides structure and support to various parts of the body. In the case of the earlobe and the tip of the nose, cartilage helps maintain their shape and allows for flexibility and movement.

The correct answer is "Sendi." Sendi refers to the joints that connect one bone to another. They allow for movement and flexibility in the skeletal system. Without joints, our bones would not be able to function properly and perform various movements. Therefore, it is the joints that connect one bone to another, not muscles (otot), the skeletal system (rangka), or collagen (kolagen).

Osteoporosis is a common bone disorder that occurs in older individuals. It is characterized by a decrease in bone density and strength, leading to an increased risk of fractures. This condition is more prevalent in older adults due to the natural aging process, which causes a decline in bone mass. Osteoporosis is often asymptomatic until a fracture occurs, making it a significant concern for the elderly population. Therefore, osteoporosis is the most likely bone disorder to occur in older individuals.

The given options are all types of bones that are part of the human body. However, "Tulang lengan" is not a correct term in Indonesian. The correct term for the bones in the arm is "Tulang lengan atas" (bones of the upper arm) and "Tulang lengan bawah" (bones of the lower arm). Therefore, "Tulang lengan" is not a valid option and is the answer to the question.

Tulang keras tersusun dari kolagen dan kalsium. Kolagen memberikan kekuatan dan fleksibilitas pada tulang, sementara kalsium memberikan kekerasan dan kepadatan. Kolagen adalah protein yang membentuk kerangka tulang, sedangkan kalsium adalah mineral yang memberikan kekerasan pada tulang. Kombinasi kolagen dan kalsium membuat tulang menjadi kuat dan tahan lama.

Otot lurik memiliki ciri-ciri yang sesuai dengan pernyataan yang diberikan. Otot lurik berfungsi dalam pergerakan tubuh, seperti gerakan lengan dan kaki. Otot lurik juga bekerja di bawah kesadaran kita, seperti saat kita berjalan atau mengangkat sesuatu tanpa kita sadari. Selain itu, struktur otot lurik memiliki pola gelap dan terang yang terlihat saat dilihat di bawah mikroskop. Oleh karena itu, jawaban yang tepat adalah otot lurik.

Tulang berperan dalam memberikan bentuk tubuh kita. Tulang-tulang ini membentuk kerangka yang memberikan struktur dan bentuk tubuh. Tanpa tulang, tubuh kita tidak akan memiliki bentuk yang jelas dan kokoh. Tulang juga berfungsi sebagai penyangga bagi organ-organ tubuh lainnya.

The correct answer is Lordosis. Lordosis is a condition where there is an excessive inward curvature of the spine in the lower back. This can be caused by poor posture, such as sitting in a slouched position for extended periods of time. In the given image, the disturbance in the bone is likely due to the incorrect sitting posture, leading to lordosis. Kifosis refers to an excessive outward curvature of the spine, skoliosis refers to a sideways curvature of the spine, and fraktura refers to a bone fracture.

Otot polos bekerja di bawah kesadaran kita, bukan di luar kesadaran kita. Otot polos tidak dapat kita kendalikan secara sadar, melainkan bekerja secara otomatis untuk mengatur fungsi-fungsi tubuh seperti peristaltik usus, kontraksi pembuluh darah, dan kontraksi rahim.

The correct answer is "Tulang pipih." Tulang pipih refers to flat bones, such as those found in the skull. These bones have a thin, flat shape and provide protection for vital organs, as well as support for muscles and other tissues. Unlike irregular bones, which have complex shapes, flat bones have a relatively simple and flat structure.

The correct answer is "Tulang pendek dan tulang pipih." This answer is correct because it states that "Tulang pendek dan tulang pipih" is not a form of bone. This implies that the other options, "Tulang bundar dan tulang pipih," "Tulang bundar dan tulang dada," and "Tulang bundar dan tulang pendek," are forms of bone.

The correct answer is "Sendi Peluru". A ball and socket joint, also known as a "Sendi Peluru", allows for free movement in almost all directions. This type of joint consists of a rounded end of one bone fitting into a cup-shaped socket of another bone. It provides a wide range of motion, allowing for movements such as rotation, flexion, extension, abduction, and adduction.

Otot bisa mengembang dan mengkerut untuk menggerakkan tulang. Ketika otot mengembang, tulang akan bergerak ke arah tertentu. Sedangkan ketika otot mengkerut, tulang akan kembali ke posisi semula.
