Question: An electromagnetic wave refractor in some aperture antennas is a component which due to its shape and position functions to selectively delay or advance portions of the electromagnetic wavefront passing through it. The refractor alters the spatial characteristics of the wave on one side relative to the other side. It can, for instance, bring the wave to a focus or alter the wave front in other ways, generally in order to maximize the directivity of the antenna system. This is the radio equivalent of an optical lens.
Try to answer this question if possible: What changes the structuak traits of a wave on either side?
Answer: refractor
Question: Epigenetic changes in eukaryotic biology serve to regulate the process of cellular differentiation. During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells. A single fertilized egg cell, the zygote, gives rise to the many different plant cell types including parenchyma, xylem vessel elements, phloem sieve tubes, guard cells of the epidermis, etc. as it continues to divide. The process results from the epigenetic activation of some genes and inhibition of others.
Try to answer this question if possible: What is the original cell of the plant?
Answer: the zygote
Question: Kievan Rus', although sparsely populated compared to Western Europe, was not only the largest contemporary European state in terms of area but also culturally advanced. Literacy in Kiev, Novgorod and other large cities was high. As birch bark documents attest, they exchanged love letters and prepared cheat sheets for schools. Novgorod had a sewage system and wood paving not often found in other cities at the time. The Russkaya Pravda confined punishments to fines and generally did not use capital punishment. Certain rights were accorded to women, such as property and inheritance rights.
Try to answer this question if possible: What were some of the rights women had during this time period?
Answer: property and inheritance rights
Question: In Sand Springs, an outdoor amphitheater called "Discoveryland!" is the official performance headquarters for the musical Oklahoma! Ridge Bond, native of McAlester, Oklahoma, starred in the Broadway and International touring productions of Oklahoma!, playing the role of "Curly McClain" in more than 2,600 performances.

Bond was instrumental in the title song becoming the Oklahoma state song and is also featured on the U.S. postage stamp commemorating the musical's 50th anniversary. Historically, the state has produced musical styles such as The Tulsa Sound and western swing, which was popularized at Cain's Ballroom in Tulsa. The building, known as the "Carnegie Hall of Western Swing", served as the performance headquarters of Bob Wills and the Texas Playboys during the 1930s. Stillwater is known as the epicenter of Red Dirt music, the best-known proponent of which is the late Bob Childers.
