      Manis, asam, pahit

    Correct Answer
    D. Manis, asin, pahit
    Explanation
    The correct answer is "Manis, asin, pahit". This is because the question is asking about the sequence of tastes that can be sensed on different parts of the tongue. According to the question, the tastes that can be sensed are sweet (manis), salty (asin), and bitter (pahit). Therefore, the correct answer is the one that lists these tastes in the correct order.

    Rate this question:

  • 3. 

    Bagian mata yang berfungsi sebagai diafragma adalah ….

    • A.

      Kornea

    • B.

      Retina

    • C.

      Lensa

    • D.

      Iris

    • E.

      Pupil

    Correct Answer
    D. Iris
    Explanation
    The iris is the part of the eye that functions as a diaphragm. It controls the size of the pupil, which regulates the amount of light entering the eye. The iris contains muscles that contract or expand to adjust the size of the pupil, depending on the lighting conditions. This mechanism helps to protect the sensitive retina from excessive light and allows for clear vision in different lighting environments.

    Bagian yang membantu reseptor pembau menerima rangsangan gas kimia merupakan fungsi ….

    • A.

      Papilla

    • B.

    • C.

      Ludah

    • D.

      Lendir hidung

    • E.

      Rambut-rambut hidung

    Correct Answer
    D. Lendir hidung
    Explanation
    Lendir hidung membantu reseptor pembau menerima rangsangan gas kimia karena lendir tersebut berfungsi sebagai penangkap partikel-partikel kimia di udara yang masuk melalui hidung. Lendir ini mengandung reseptor pembau yang peka terhadap zat-zat kimia tertentu, sehingga ketika zat kimia tersebut masuk ke dalam hidung, reseptor pembau akan meresponsnya dan mengirimkan sinyal ke otak untuk diinterpretasikan sebagai bau.

      Iris

    • D.

      Kornea

    • E.

      Lensa

    Correct Answer
    A. Retina
    Explanation
    The given passage describes the cells in the middle layer of the eye, which consists of approximately 100 million rod-shaped cells and 3 million cone-shaped cells. This description matches the characteristics of the retina, which is the light-sensitive layer at the back of the eye responsible for converting light into electrical signals that are sent to the brain for visual processing. The other options (pupil, iris, cornea, and lens) do not match the description provided in the passage.

      Rodopsin

    • C.

      Retina

    • D.

      Bintik kuning

    • E.

      Bintik buta

    Correct Answer
    B. Rodopsin
    Explanation
    Rodopsin adalah zat warna jingga yang sangat rentan terhadap cahaya yang dihasilkan oleh sel-sel batang dalam retina. Rodopsin berperan penting dalam penglihatan pada kondisi pencahayaan rendah atau gelap. Ketika cahaya masuk ke mata, rodopsin akan teraktivasi dan mengirimkan sinyal ke otak untuk diproses menjadi gambar yang dapat kita lihat. Jadi, rodopsin merupakan zat yang dihasilkan oleh sel-sel batang dan berfungsi dalam penglihatan dalam kondisi pencahayaan rendah.

    • E.

      Iris

    Correct Answer
    A. Sklera
    Explanation
    The given passage describes the structure of the eye and mentions that the layer in front, called the cornea, is transparent and responsible for receiving and focusing incoming light. Among the options given, the only one that matches this description is the "sklera." The sklera is the white outer layer of the eye that covers most of its surface, while the other options mentioned (retina, bintik kuning, bintik buta, iris) do not fit the given information.

    Correct Answer
    B. 2) dan 1)
    Explanation
    The correct answer is 2) dan 1). This is because the Ruffini corpuscles are responsible for perceiving heat, while the Paccini corpuscles are responsible for perceiving strong pressure. Therefore, the correct combination for perceiving heat and strong pressure is 2) dan 1).

    Correct Answer
    A. Martil (mileus) - landasan (inkus) - sanggurdi (stapes)
    Explanation
    The correct answer is martil (mileus) - landasan (inkus) - sanggurdi (stapes). This is the correct sequence of the auditory ossicles in the middle ear. The malleus (martil) is the first bone, followed by the incus (landasan), and then the stapes (sanggurdi).

    • E.

      Korpuskel Krausse

    Correct Answer
    B. Korpuskel Meissner
    Explanation
    The correct answer is korpuskel Meissner. The Meissner corpuscle is a sensory receptor found in the skin that is responsible for detecting light touch and low-frequency vibrations. It is located in the upper layers of the skin, particularly in the fingertips, palms, soles of the feet, and lips. When stimulated by touch or pressure, the Meissner corpuscle sends signals to the brain, allowing us to perceive and respond to tactile sensations.

    • D.

      Tulang landasan

    • E.

      Tulang sanggurdi

    Correct Answer
    A. Koklea
    Explanation
    The correct answer is "koklea." The cochlea is a part of the inner ear that is responsible for hearing. It is shaped like a snail shell and contains tiny hair cells that convert sound vibrations into electrical signals that can be interpreted by the brain. The cochlea plays a crucial role in our ability to perceive and process sound.

  • 15. 

    Membran timpani adalah pembatas dari telinga bagian tengah dan telinga bagian tengah

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The given statement states that the tympanic membrane is the boundary between the middle ear and the outer ear. This is true because the tympanic membrane, also known as the eardrum, separates the external auditory canal from the middle ear cavity. It vibrates in response to sound waves and transmits them to the middle ear bones, which then transmit the sound to the inner ear for further processing. Therefore, the statement is correct.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Presbikus is not a condition caused by loud noises, but rather it refers to age-related hearing loss. It is a gradual and natural decline in hearing ability that occurs as people get older. Loud noises can contribute to hearing loss, but they do not specifically cause presbikus. Therefore, the correct answer is false.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
