This happens because taproot formation is impossible, so trees developed shallow root beds.
Permafrost is soil that has a temperature below 0 °C (for about two years) and forms a solid matrix which can extend to a depth of hundreds of meters. Because of this structure the permafrost prevents trees from developing deep root systems. As a consequence, the shallow root bed of trees such as black spruce, causes them to lean or even fall.
Answer:
In chronic hypertension the baroreceptors get used to high blood pressure and does not respond effeciently.
Explanation:
Hypertension is the condition when blood pressure usually remains higher than normal. The systolic higher blood pressure is considered high above from 139 (mmHg) and diastolic is considered as above from 89 (mmHg).
The condition is considered to be chronic when it affects vital organs such as lung and hurt. There are several stimuli to which brain response to maintain normal blood pressure. Most important and fast of these is baroreceptors present in blood vessels that detect the change in blood pressure and signal to brain for proper response such as dilating the blood vessels in case of high blood pressure.
In coronary hypertension the walls of blood vessels become stiffer due to several factors such as smoking, stress and ageing. The high blood pressure produces tension in the wall of artery which is detected by baroreceptor. In coronary hypertension these barorecepetors get used to higher blood pressure thus does not response to it properly. So blood pressure remains high.
