Most churches do not charge for the funeral service of an active member of their congregation, but it can be customary to give a donation of $50-$200 or more to the church. Non-members may be charged rental fees of $200-$500 or more, depending on the number and type of facilities, and the length of time they are needed.
A chemoreceptor, also known as chemosensor, is a sensory receptor that transduces a chemical signal into an action potential. In more general terms, a chemosensor detects certain chemical stimuli in the environment. Examples of direct chemoreceptors include: 2  Taste buds in the gustatory system: The primary use of gustation as a type of chemoreception is for the detection of tasteants. 3  Aqueous chemical compounds come into contact with chemoreceptors in the mouth, such as taste buds on the tongue, and trigger responses.
All of these nerve cells send impulses back to the brain. Chemoreceptors can also be found in the brain itself, monitoring pH level and alerting the brain to the presence of chemicals which could indicate a problem. A special area of the brain called the chemoreceptor trigger zone receives input from those receptors which are sensitive to chemicals which can be dangerous.
