Astronomers use the distancebetween Earth and sun, which is 93 million miles, as a new unit of measure called the Astronomical Unit. It is defined to be exactly 1.00 for the Earth-Sun orbit distance, and we call this distance 1.00 AUs.
Answer:
Well, first off, I live in America. In America, it is night time per se. And on the other side of the earth, it is the afternoon. Because, the earth orbits the sun. So, it changes depending on the time of day it is.
Explanation:
Wind affects plant growth, reproduction, distribution, death, and ultimately plant evolution. Some of the effects depend on the air boundary layers next to the aerial parts of a plant, across which gas and heat exchanges with the environment occur.
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.
