The right option is; B. They carry neural signals about a sound wave’s frequency to the brain.
The cochlea is the sense organ that converts sound into neural signals that is sent to the brain. The cochlea contains hair cells that are responsible for hearing. The lower part of the hair cells are joined to the basilar membrane. Within the cochlea, sound waves make the basilar membrane to vibrate up and down and to generate nerve impulses. Below the hair cells are the auditory nerve fibers which pass the signals about a sound wave’s frequency to the brain.
Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
When an animal eats, food stays in the stomach for a period of time. When a unicellular organism, such as Paramecium, takes in food, the food is contained in which organelle? Amino acids link together by peptide bonds to form proteins.
