This fuel are used by vehicles, heavy machines to generate energy. The energy is a nonrenewable one.
Therefore, The increasing use of internal combustion engines could eventually deplete petroleum energy.

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.
