What does the place theory of pitch perception suggest? different amplitudes of the basilar membrane are sensitive to sounds of different waves. different portions of the basilar membrane are sensitive to sounds of different frequencies. different portions of the ear are sensitive to sounds of different decibels. different sections of the cochlea are sensitive to sounds of different frequencies?

Option B

Explanation:

The pitch perception theory suggests that the basilar membrane of the ear responds differently to the different sound frequency.

The base of the base of the this membrane responds best to the high frequency and the low frequency sound is responded by the tip of the basilar membrane.

The hair at the base is best suited for high pitch receptors and tip of the hair are high frequency receptor.

The correct answer is option B

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
