A light microscope image of a purple sea urchin
(Strongylocentrotus purpuratus) egg after fertilization. The outer circle area is called the vitellien layer. Purple sea urchins may be found on rocky bottoms and grazing intertidal and subtidal waters. They feed primarily on algae and brown kelp.
Within an atom, electrons surround a nucleus composed of protons and neutrons in an electron configuration.
When electrons and positrons collide, they annihilate each other and produce pairs of high energy photons or other particles. On the other hand, high-energy photons may transform into an electron and a positron by a process called pair production, but only in the presence of a nearby charged particle, such as a nucleus.

Sublimation of an element or substance is a conversion between the solid and the gas phases with no intermediate liquid stage. Sublimation is a phase transition that occurs at temperatures and pressures below the triple point
At normal
pressures, most chemical compounds and elements possess three different states at different temperatures. In these cases the transition from the solid to the gaseous state requires an intermediate liquid state. However, for some elements or substances at some pressures the material may transition directly from solid to the gaseous state. Note that the pressure referred to here is the vapor pressure of the substance, not the total pressure of the entire system.
opposite of sublimation is deposition. The formation of frost is an example of meteorological deposition.
