Which sensory system(s) have receptors which die after awhile because it/they have direct exposure to the environment?\?

Anika [276]

The OLFACTORY AND THE GUSTATORY SYSTEMS have receptors which die out after sometimes because of direct exposure to the environment.
The olfactory system has to do with the perception of smell while the gustatory system has to do with taste stimuli. For these two basic sense organs, their perception rate is always highest when they are newly exposed to a stimuli, after continuous exposure to the stimuli their receptors die out.

What is the purpose of the electron transport chain in the thylakoid membrane?

Feliz [49]

Answer:

To produce energy in form of ATP

Explanation:

The thylakoid membrane harbors photosystems that will receive light photons, ejecting electrons from a main chlorophyl molecule in a reaction center, to other acceptors. These electrons will reach the electron transport chain to create a proton gradient, and subsequently, to produce ATP. Later on these electrons will reach the other photosystem, to produce reducing power. This is in plants.

Cyclic photosystems also exist, in some bacteria, for example, and only produce energy as ATP. They also have an electron transport chain.

Kristen cut her hand on a piece of glass. As the blood clots, how do white blood cells prevent bacteria on the glass from infect

gayaneshka [121]

So white blood cell’s(WBCs for short) main job is to fight infections.
They do this by swallowing the infection.

You see,WBCs do not have a permanent shape.this means that they enlarge and decrease size of parts of their body.So they grow two long arm like structures called pseudopodia which swallow the infection.(pseudopodia means false feet).
You can see the process in the photo I attached from google
