a border
A mountain range can serve as a barrier between different regions or countries, preventing easy passage.
It is, for example, a buffer zone between two hostile nations that serves to prevent conflict
The nuclear envelope also serves as the physical barrier, separating the contents of the nucleus (DNA in particular) from the cytosol (cytoplasm) basically, keeps the DNA safe, and separates the nucleus from the rest of the cell
According to the Urban Dictionary, buffer is The name by which gypsies call people who live on the grid, with social security numbers, attend school, and own a home. A buffer is the term that the gypsies call basically real people, whom they lift stuff off of.
The dividing line between North and South Korea is the Korean Demilitarized Zone (DMZ), which is a buffer zone established by the Korean Armistice Agreement signed in 1953. The DMZ runs along the 38th parallel north, effectively separating the two countries. This heavily fortified area is approximately 2.5 miles wide and stretches for about 160 miles across the Korean Peninsula. It serves as a symbol of the ongoing tensions and division between the two Koreas.
A saturated buffer is a specific type of buffer designed to treat runoff water from agricultural fields by allowing it to pass through a vegetated area slowly. It serves a similar function as traditional buffers by capturing nutrients and sediment, but its design is tailored for certain conditions.
The bicarbonate ion (HCO3-) present in seawater serves as a buffer, helping to maintain the pH balance of the ocean. It plays a key role in absorbing excess carbon dioxide from the atmosphere, contributing to the regulation of ocean acidity levels.
A buffer zone is a designated area that serves as a protective space between different land uses or environments, often to minimize conflict or mitigate impacts. It can be used in various contexts, such as environmental conservation, military operations, or urban planning, to provide a barrier against pollution, disturbances, or encroachments. The concept aims to enhance safety, preserve natural resources, and promote coexistence between conflicting interests.
India is separated from China by the Himalaya mountains. This natural barrier spans across the northern borders of India and serves as a geographical divide between the two countries.
It serves to break the tissue apart so the DNA can be subsequently extracted.

Salt in a buffer helps to maintain a constant ionic strength, which can affect the stability and effectiveness of the buffer solution. It also helps to minimize changes in pH that may occur due to dilution or added components.
