All the populations of organisms living close enough together for potential interaction make up a community!
soil, rock, organic layer
Explanation:
Permeability is the ability of a layer of rock to transmit fluid such as oil or water
The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter
Rocks such as gravels, and sparingly cemented sands have high permeability
The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water
Therefore, water moves easily between layers soil, rock, organic layer
The answere is D. Shallow ground water because it is evaporated quickly
Answer: Oligodynamic and unaffected by antimicrobial resistance
Explanation:
Silver is one of the most affected effective antimicrobial which is so effective that the microbes die when being exposed to the silver.
It is used in case of wound dressing, and it is used to coat medical devices . It is used as an external application such as on the skin and while dressing.
The oligodynamic action of the metal is to block the free carbonyl and sufhydryl group present in the organism.
Even in the small concentration it can be used to kill the microbes.
