The test may cause momentary gagging because the back of the throat is a sensitive area, but it should not be painful. The sample your doctor collects is taken to a laboratory, where it is put on a plate that allows any bacteria on it to grow. This process is called a culture.
Often these are called transition zones which represent the start and end of a specific region and can be large or small. For example, the transition zone between Sub-Saharan Africa and North Africa is rather large because there is a mixing between the two regions. Regional geographers study this zone as well as the distinct characteristics of Sub-Saharan Africa and North Africa.
On a glacier, the accumulation zone is the area above the firn line, where snowfall accumulates and exceeds the losses from ablation, (melting, evaporation, and sublimation).The annual Glacier equilibrium line separates the accumulation and ablation zone annually.The accumulation zone is also defined as the part of a glacierâs surface, usually at higher elevations, on which there is net accumulation of snow, which subsequently turns into firn and then glacier ice.Part of the glacier where snow builds up and turns to ice moves outward from there.he accumulation zone is also defined as the part of a glacierâs surface, usually at higher elevations, on which there is net accumulation of snow, which subsequently turns into firn and then glacier ice.
