Answer: A.
Explanation: When a chlorine atom gains an electron, its outermost principal energy level achieves an octet. In this case, the ion has the same outermost shell as the original atom, but now that shell has eight electrons in it.

<em>Rocks erode and sediment is deposited, and No sediment is deposited over a long time.</em>
<u>Explanation:</u>
The most common reason for the formation of <em>uncomformity is erosion</em>. The <em>times of formation of the rocks</em> above and below the uncomformity are different when no sediment is deposited over a long time.
The rock above the uncomformity are younger than the rocks below the uncomformity. Types of uncomformity are <em>angular uncomformity, discomformity and non comformity.</em>
In angular discomformity horizontal sedimentary rock layers are formed above sedimentary rock layers that are in tilted position. Discomformity lies between two <em>horizontal sedimentary rock layers</em>. Non comformity lies between<em> sedimentary and igneous rock layers or metamorphic rocks.</em>
The best answer would most likely be genetics or genetic theory.
There were many doubts about Darwin's theory because Darwin could not yet describe the mechanism of inheritance. Mendel's work on inheritance was already published, 2 years earlier, but this eluded Darwin. It was only till after Darwin's death that the science of genetics came about.
This union brought about the "modern synthesis," a theory that proposes that both genetics and natural selection is a result of evolutionary changes.
