Answer:
In communication between cells, the SIGNALING CELL produces the signaling molecule, also known as the LIGAND; the RESPONDING CELL produces the RECEPTOR, to which the signaling molecule binds,
Explanation:
The term cell signaling refers to the mechanisms by which cells communicate with one another and mainly includes cells, ligands, and receptors. To send a signal, the signaling cell synthesizes and release signaling molecules called ligands. The ligands are to be transported if the responding cells are distantly located.
As the signal molecule reaches the responding cell, it binds to the receptors present on the surface of the responding cells. This process is called reception as the responding cell receives the signals. Some cells produce cytosolic or nuclear receptors for their signaling molecules.
I cannot find the propositions, so I just define what an alpha particle is:
Alpha particles (or alpha rays) are a form of radiation emitted by unstable nuclei of great atomic mass (alpha decay). They consist of two protons and two neutrons combined into a particle identical to the helium nucleus, so they can be written 4He2+ (or 4α2+). (the nuclei will lose 2 positive charges and 4 atomic masses)
Unlike other particles, a Beta particle is the emission of an electron (or a position), and gamma rays (not a particle) is the emission of a ray photon very high energy light.
I hope this could help you with you answering the question.
