Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur.

Summary of hearing: Vibrations cause the cochlea’s membrane to shake. This causes ripples in the ____________, bending the _____

mash [69]

Answer:

1) Basilar membrane

2) Stereocilia or hair cells

3) Nerve cells

4) Auditory

5) Temporal lobe

Explanation:

Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.

Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.

Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.

Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.

Compare the amount of ATP made during aerobic cellular respiration to the amount of ATP made during anaerobic cellular respirati

andreyandreev [35.5K]

The answer is C. Because aerobic cellular respiration includes oxygen in the process, more ATP (specifically 36-38 ATP) is produced. Because anaerobic cellular respiration does not include oxygen in the process, it only produces 2 ATP.
