For a brief time, a supernova can shine as brightly as an entire galaxy, but will fade again over a matter of days. The explosion occurs when a high-mass star finally runs out of nuclear fuel. ... The resulting shock wave creates an expanding shell of gas and dust called a supernova remnant.
The products of photosynthesis are sugar molecules (glucose) and oxygen. <span>Photosynthesis is the process in which light energy is converted to chemical energy. In this process, water and carbon dioxide combined with light energy produce glucose molecules (or other sugars) and oxygen is released as a byproduct. The glucose molecules provide organisms with two crucial resources: energy (glucose contains chemical energy) and fixed organic carbon atom. The energy of glucose is used in the process called cellular respiration where adenosine triphosphate-ATP is generated.</span>

Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.
