Those of us who use sun glasses must've noticed that some sun glasses block both UV A as well as UV B What is the difference between UV A and UV B?

UV A are long wave solar rays while UV B(more dangerous than UV A) are short wave solar rays. SPF(sun protection factor) mentioned on sunscreen creams protects against UV B.

PETN is non metallic therefore X ray machines are unable to detect it.

Yes, it is plastic in nature and can be carried through detectors easily. Even sniffer dogs can miss it if it is inside some tight container!!
Thats why its use is very regulated (mostly used by military).

Kala rang baaki rango ka adhikta mein hone ke karan banta hai. Chai ke kale rang mein lal rang ki adhikta hoti hai jisme safed rang milne se kalapan kam ho jata hai aur wo lalima le leta hai.

From Wikipedia:

The age at which graying begins seems almost entirely due to genetics. Sometimes people are born with gray hair because they inherit the trait.

Two genes appear to be responsible for the process of graying, Bcl2 and Bcl-w.[citation needed] The change in hair color occurs when melanin ceases to be produced in the hair root and new hairs grow in without pigment. The stem cells at the base of hair follicles produce melanocytes, the cells that produce and store pigment in hair and skin. The death of the melanocyte stem cells causes the onset of graying.[10]

During tea leaf processing, redish brown- orangish colored compounds (Theaflavins, Thearubigins etc) are produced which are released in the tea extract made from hot water. The black color of tea leaves is not water soluble, hence it gets sieved out with the tea leaves. When this orangish-red-brown extract gets mixed with white milk, the resultant color is a lighter shade of the original extarct.
