WHOEVER ANSWERS FIRST GET A BRAINLY!!!!Provide a reason why no 2 communities are ever the same. Support your answer with an exam
Advocard [28]

Answer:

No two communities are the same because each one has something specific to them whether it is house structure, rules of the community, how big the community is, and the people that live there.

Explanation:

A great example of this is Weston, FL and Pembroke Pines, FL. In Weston you will find higher class people living there such as celebrities and athletes. The best community to use as a comparison is Botanica Weston. There are mansions in that neighborhood along with many sport icons living there. In Pembroke Pines, it is more of a family based city. In the community Pembroke Falls, you will see more family type houses and a large clubhouse with a pool, game room, and event room to host parties in. Each community has a different identity and no two communities are the same.

Contractions of the heart generate blood pressure, which is responsible for moving blood through the blood vessels.
malfutka [58]

The contractions of the heart is what creates out blood to pulse through out body and is the basis of our blood pressure; which means this statement is TRUE.


The systolic number (top) of the blood pressure is our heart physically pushing the blood out of the heart and to the rest of the body.

The outer hair cells respond to sound by slightly tilting and changing length. because of the consequence of this, the action of
serg [7]

Basilar membranes

In an active cochlea, basilar membranes vibrate more strongly than in a dead cochlea. because all of the outer hair cells slant significantly and alter in length in response to sound. In response to basilar membrane changes, outer hair cells swell and contract. The frequency tuning curve is impacted by damage to the outer hair cells.

<h3>What are the function of Basilar membranes?</h3>

The basilar membrane is the inner ear's primary mechanical component. Over its length, it has graded mass and stiffness characteristics, and its vibration patterns separate incoming sound into its component frequencies, which trigger various cochlear areas.

Impact do outer hair cells have on our hearing :

As a nonlinear amplifier that enables the cochlea to detect sounds with great sensitivity and accuracy, outer hair cells (OHCs) play a crucial role in hearing. These distortion products can be monitored as distortion-product otoacoustic emissions as a result of the nonlinear sound processing (DPOAEs)
