Coarse adjustment is used to focus the image on the microscope under low or medium power by using larger motions of the lens. (Note: Coarse adjustment should never be used during High power)\n\nFine adjustment is used to focus the image on the microscope of only high power by using very tiny motions of the lens.

Plants take in oxygen, carbon dioxide and water, and produce sugar which contains carbon, oxygen and hydrogen atoms from all three. So they use more water than they put out. In fact, I don't believe they "exhale" water the way we do at all,

Note the answers on 2, 3, 5 and 7 ... that's where we all differ.\n\n1) organic compounds\n2) oxygen or respiration (the question is not clear)\n3) molecular basis for genetics (not chromosomes ... some DNA is outside the chromosomes ... and there's no RNA in chromosomes)\n4) condensation\n5) lobster (ask anyone from Maine)\n6) freezing or solidification\n7) weight (not mass ... mass is the amount of gravity exerted *by* the object, not acting *on* it.  I.e. mass is independent of the gravity acting on it ... since the more gravity experienced, the more it weighs, weight is more correct). \n8) boiling or vaporization (or if you're in England, vapourisation)
