QUES: The oak forests of the southern and central Appalachians consist largely of black, northern red, white, chestnut and scarlet oaks (Quercus velutina, Q. rubra, Q. alba, Q. prinus and Q. coccinea) and hickories, such as the pignut (Carya glabra) in particular. The richest forests, which grade into mesic types, usually in coves and on gentle slopes, have dominantly white and northern red oaks, while the driest sites are dominated by chestnut oak, or sometimes by scarlet or northern red oaks. In the northern Appalachians the oaks, except for white and northern red, drop out, while the latter extends farthest north.

QUES: The sensors are primarily single cells that detect light, chemicals, pressure waves and contact, and are present on the head, appendages (if any) and other parts of the body. Nuchal ("on the neck") organs are paired, ciliated structures found only in polychaetes, and are thought to be chemosensors. Some polychaetes also have various combinations of ocelli ("little eyes") that detect the direction from which light is coming and camera eyes or compound eyes that can probably form images. The compound eyes probably evolved independently of arthropods' eyes. Some tube-worms use ocelli widely spread over their bodies to detect the shadows of fish, so that they can quickly withdraw into their tubes. Some burrowing and tube-dwelling polychaetes have statocysts (tilt and balance sensors) that tell them which way is down. A few polychaete genera have on the undersides of their heads palps that are used both in feeding and as "feelers", and some of these also have antennae that are structurally similar but probably are used mainly as "feelers".

QUES: Two of Chopin's long-standing pupils, Karol Mikuli (18211897) and Georges Mathias, were themselves piano teachers and passed on details of his playing to their own students, some of whom (such as Raoul Koczalski) were to make recordings of his music. Other pianists and composers influenced by Chopin's style include Louis Moreau Gottschalk, Edouard Wolff (18161880) and Pierre Zimmermann. Debussy dedicated his own 1915 piano Etudes to the memory of Chopin; he frequently played Chopin's music during his studies at the Paris Conservatoire, and undertook the editing of Chopin's piano music for the publisher Jacques Durand.
