Answer to Question 1

The glass is classified as No. 10 shade. The welding arc contains light rays that burn, even from a
distance. Any material that blocks the light also stops the damaging rays because the human eye must
not be exposed to direct light from the welding arc.



Answer to Question 2

GMAW is gas metal arc welding. It is a method of welding where wire is fed automatically at a
constant speed as an electrode. It is used in welding exhaust systems, repairing mechanical supports,
installing trailer hitches, truck bumpers, and aluminum castings.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.

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).
