Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.
The stabilization of a radioactive parent element into a stable daughter element occurs through the process of radioactive decay. The unstable atomic parent emits radiation and loses its energy. This leads to the formation of a daughter element, which is less radioactive or is stable.
Just like a Lego house is made of bricks, proteins are made up of lots of tiny building blocks. These building blocks are called amino acids. To build a protein, first the amino acids are connected into long chains.

A neurotransmitter is a chemical substance that is released by a nerve fiber due to the presence of nerve impulses; it transport chemical information from one nerve to the other. A receptor refers to a protein molecule that is found on the cell membranes of every cell, it functions by responding in an appropriate manner to chemical signals that are coming from outside of the cell.
The relationship between the neurotransmitter and the receptor is that the neurotransmitter molecules typically bound with the appropriate receptors and bring about the expected changes in the targeted postsynaptic cell.
