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.
The Triassic /traÉªËaesÉªk/ traÉªËÃ¦sÉªk is a geologic period and system that extends from roughly 250 to 200 (mya.252 Â± 17.0 06 to.201 Â± 3.0 2 million years), ago an interval of.51 04 million. Years it is the first period of The Mesozoic, era and lies between The permian And jurassic. periodso coal deposits date from the start of the Triassic period. This is known as the coal gap and can be seen as part of the PermianâTriassic extinction event. Sharp drops in sea level at the time of the Permo Triassic boundary may be the proper explanation for the coal gap.
