Tiny regions at the surfaces of neurons and different cells which are touchy to neurotransmitters or hormones are called receptors.
The required details for receptors in given paragraph
Cellular receptors are proteins both internal a mobileular or on its floor which acquire a sign. In everyday physiology, that is a chemical sign in which a protein-ligand binds a protein receptor. The ligand is a chemical messenger launched with the aid of using one mobileular to sign both itself or a exceptional mobileular. Receptors are proteins that bind to outside messengers to create a chain of downstream consequences that mediate a selected reaction withinside the mobileular. Receptors have a ligand-binding area that acknowledges the particular ligand and the effector area that undergoes conformational modifications to provide a downstream event.
Receptors are available in many types, however they may be divided into categories: intracellular receptors, which can be determined internal of the mobileular (within side the cytoplasm or nucleus), and mobileular floor receptors, which can be determined within side the plasma membrane.

Answer:
The correct option is B) a pattern of biological functioning that occurs on a 24-hour cycle.
Explanation:
Biological rhythm is defined as the regular variation of an organic function related to the course of time, circadian biological phenomena (around the day), are those with a period of approximately 24 hours.
Circadian rhythms are physical, mental and behavioral changes that follow a daily cycle (the biological rhythm), and that respond primarily to light and darkness in an organism's environment. This cycle close to 24 hours, allows to recognize the sleep-wake phenomena and their homeostatic action, in the systemic processes of every living being. The circadian system is composed of photoreceptors, pacemakers and efferent pathways that allow a regular functioning of the sleep and wakeful state.
This is called the prophase which is the second stage of mitosis.
So it's going to be obviously oxygen XD ....so that's one
Next, it's going to be carbon dioxide, since it has to exit the cell, because it is a waste product ...so that's two
Finally, it's also going to be something you drink everyday.
*whispers* it's water XD because of osmosis
So recap:
1) Oxygen 2) Carbon Dioxide 3) Water
hope that helps!! :D
