If for a short period of time circuits goes to some different logic level then it is spposed to have then it is called static hazard. e.g., If the final logic value of output of given circuit becomes one vent if if is supposed to be zero then it is called static-0 Hazard and vice versa. Dynamic Hazard is the one in which the circuit output goes to some other logic level more than once then finally settling down to some appropriate level.

Biogeochemical cycles are crucial to ecosystem function because ::

1. Chemical elements are available in only limited amounts and must be recycled.

2. Nutrients and other life-sustaining molecules are in limited supply and must be continually recycled.

The primary agent of contact metamorphism is heat or temperature.

In the early 1950s two scientists, Rosalind Franklin and Maurice Wilkins, studied DNA using x-rays. Franklin produced an x-ray photograph that allowed two other researchers, James Watson and Francis Crick to work out the 3D structure of DNA. The structure of DNA was found to be a double helix.

A stupa is a mound-like or hemispherical structure containing relics that is used as a place of meditation.Buddhist sources claim that during the 3rd century BCE, the Mauryan Emperor Ashoka the Great ordered these eight stupas to be opened, further distributed the relics of the Buddha into 84,000 portions, and had stupas built over them all over the expanding Buddhist world.They were located on trade routes in order to propagate Buddhism.However, there were no evidence of them being located in rural areas.
