Explanation:
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins.
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.

Answer:
Teeth enables us to chew food properly.........
The following protocols in the facility would the care aide advocate changing are D) Wound dressings are applied promptly to all identified or potential pressure ulcers.
Dressings must be modified often and as quickly as they grow to be dirty with urine or feces to save you wound contamination. Each dressing extrade must be observed through concurrent wound reassessment.
hydrocolloid dressings – include a gel that encourages the boom of latest pores and skin cells withinside the ulcer, whilst retaining the encompassing wholesome pores and skin dry. different dressing types – which include foams, films, hydrofibres/gelling fibres, gels and antimicrobial (antibiotic) dressings can also be used.
