Answer to Question 1

The travel of a laser beam can be timed from one plate to another by bouncing it from a satellite and
by calculating the difference in arrival times of a quasar signal at two plates over a period of time.



Answer to Question 2

Hot spots appear to be fixed in the mantle relative to each other, so they can be used as a reference
frame. If the age of a basalt and its distance from the hot spot is determined, then the rate of movement
of that rock can be calculated. If a number of these samples are taken from various distances from the
hot spot, the calculation can be quite accurate.

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
