In geology, a key bed (syn marker bed) is a relatively thin layer of sedimentary
rock that is readily recognized on the basis of either its distinct
physical characteristics or fossil content and can be mapped over a very
large geographic area.[1]
As a result, a key bed is useful for correlating sequences of
sedimentary rocks over a large area. Typically, key beds were created as
the result of either instantaneous events or (geologically speaking)
very short episodes of the widespread deposition of a specific types of sediment. As the result, key beds often can be used for both mapping and correlating sedimentary rocks and dating them. Volcanic ash beds ( and bentonite beds) and impact spherule beds, and specific megaturbidites
are types of key beds created by instantaneous events. The widespread
accumulation of distinctive sediments over a geologically short period
of time have created key beds in the form of peat beds, coal beds, shell beds, marine bands, black in cyclothems, and oil shales. A well-known example of a key bed is the global layer of iridium-rich impact ejecta that marks the Cretaceous–Paleogene boundary (K–T boundary). Please let me know if it works.
The empress of India during this period; the so called Sepoy Rebellion was Queen Victoria of the British Empire, who was now also consequently the queen of India.
Her reign was a very specific and characteristic rule where she enforced different rules and made different changes to the everyday life of people.

The cells of animals, plants, and fungi, as well as those of algae and other protists, all engage in cellular respiration.
- Cellular respiration is the process that all living things use to convert organic molecules into energy.
- The chemical process that breaks down food molecules to produce adenosine triphosphate, which is used for energy, is known as cellular respiration (ATP). As a result, organisms can now use energy from food molecules to perform everyday tasks.
- Oxygen is normally present when cells respire. This is called aerobic respiration. Anaerobic respiration occurs when oxygen is absent or present in very small amounts.
- Anaerobic respiration is essential to the life of some organisms, including many bacteria. Yeast and some bacteria use an anaerobic respiration process known as fermentation. The cellular respiration equation describes the process by which glucose molecules combine with oxygen to produce energy.
Therefore, all most all organisms use cellular respiration.
