Answer to Question 1

Between 1cm to 30 cm wavelengths is a radio window that is open for communication. Even this restricted window contains millions of possible radio-frequency bands and is too wide to monitor easily, but astronomers may have thought of a way to narrow the search. Within this broad radio window lie the 21-cm spectral line of neutral hydrogen and the 18-cm line of OH. The interval between those lines has especially low background interference and is named the water hole because H plus OH yields water.

Answer to Question 2

Jovian planets do not have solid surfaces for water droplets to create organic rich oceans, and the strong atmospheric currents would quickly carry away any reproducing molecules into the hot, inhospitable regions of each respective planet.

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).
