zavuch27 [327]

Answer:

*Sensory adaptation* is the common adaptation in all three sense. Sensory adaptation is the process in which changes in the sensitivity of sensory receptors occur in relation to the stimulus. All senses are believed to experience sensory adaptation.

Explanation:

This adaptation is shared as well as used differently as explained below.

1) Hearing+balance :In terms of hearing, our ears adapt to loud sound as it hits the small bones located in the inner ear. The loud sound leads the inner ear bone/s to contract. This contraction causes the reduction or delay of transmission of sound vibrations to the inner ear. Detection of the vibrations follows. However, this process of auditory adaptation usually does not work very well with loud sounds that are sudden or instantaneous. Examples of these sounds are gun shots or explosions

2)Smell :Low concentrations of several chemicals present in the air can be detected by the sensory receptors in the nose. These chemicals that we quickly detect include those in perfumes or air fresheners

Activated charcoal is given to patients who have ingested certain substanmces because it?
mojhsa [17]

Activated charcoal adsorbs many noxious substances—medical drugs, phytotoxins and poisonous chemicals—onto its surface, preventing their absorption from the gastrointestinal tract.

<h3>What is activated charcoal ?</h3>

Activated carbon, sometimes known as activated charcoal, is a type of carbon that is frequently used for a variety of purposes, including the filtration of impurities from water and air. It is treated to have tiny, low-volume holes, which expand the surface area open to chemical reactions or adsorption.

  • For some poisonings, activated charcoal is utilised as an emergency therapy. It aids in preventing the body from absorbing the toxin from the stomach. To treat severe poisoning, activated charcoal may occasionally be given in multiple doses.
