Answer:

Explanation:

Eukaryotic cell contains both membranous and non-membranous organelles. The membranous organelles are the nucleus, endoplasmic reticulum, Golgi apparatus, chloroplast(plants), mitochondria, lysosomes, etc.

Ribosomes, centrosomes are the non-membranous structures. Ribosomes are found in both eukaryotic and prokaryotic cells. In prokaryotes 70s ribosomes are present and in eukaryotes 80s ribosomes are present. Prokaryotes do not have a membrane-bound nucleus and organelles.

Ribosomes helps in protein synthesis in both prokaryotes and eukaryotes. Therefore the right answer is the ribosome.

The sensation of hearing occurs when sensory impulses from the ears are transmitted to the auditory cortex in the _________ lobe
timofeeve [1]

Answer;

-Temporal, vestibulocochlear

-The sensation of hearing occurs when sensory impulses from the ears are transmitted to the auditory cortex in the temporal lobe from the vestibulocochlear.

Explanation;

-The vestibulocochlear nerve is responsible for both hearing and balance and brings information from the inner ear to the brain. A human's sense of equilibrium is determined by this nerve.

-Two special organs help the nerve function properly: the cochlea and the vestibular apparatus. The cochlea transforms sound waves into electrical signals that the brain can interpret. The vestibular apparatus senses changes in the position of the head in relation to gravity.

-The Temporal Lobe mainly revolves around hearing and selective listening. It receives sensory information such as sounds and speech from the ears. It is also key to being able to comprehend, or understand meaningful speech.
