HELP i need to create a story about cells and their functions the organelles are Cell membrane
Katen [24]

Answer:

More than 8.7 million species are living on the planet. Every single species is composed of a cell and it includes both single-celled and multicellular organisms.

The cells provide shape, structure and carries out different types of functions to keep the entire system active. The cell contains different functional structures which are collectively called Organelles, and they are involved in various cellular functions.

Where exactly on the map does the size and concentration of the boxes appear to be the highest?
pav-90 [236]

The concentration and size of boxes the same at all locations is not the same size. The deaths due to cholera vary depending upon the location. The relative sizes represents that died at that certain spot.

Explanation:

The black boxes represent relative numbers of death due to cholera. Cholera is referred to as a disease of poverty because of the lack of social development in the areas in which it occurs. Crowded camps are fertile ground for a cholera outbreak. Other humanitarian crises including flooding and earthquakes, civil unrest or war that causes disruption of water and sanitation systems.

zalisa [80]

Answer:

The correct answer is - option B.

Explanation:

Greenstick fractures are the type of fractures where one side of the cortex is intact and flexed while the other side is fractured. This type of fracture known as the incomplete fracture,

If any fracture have two or more lines of fracture it is called as Comminuted fractures. Impacted fractures have one segment on other. Due to the performing same activity again and again stress fracture occures that is characterized by failure of one cortical bone.

Thus, the correct answer is option B.

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)
