6、 the stability of the Black family encouraged the transmission of and so was crucial in sustaining the black heritage of folklore, music, and religious expression from one generation to another, a heritage that slaves were continually fashioning out of their African and American experiences.8, this
7、preference for exogamy, Gutman suggests, may have derived from West African rules governing marriage, which, though they from one tribal group to another, all involved some kind of prohibition against unions with close kin.9, His thesis works relatively well when applied to discrimination against Bl

10、monstrate by other methods refined structural differences among neuron types; however, proof was lacking that the quality of the impulse or its condition was influenced by these differences, which seemed instead to influence the developmental patterning of the neural circuits.12, although qualitativ
11、e variance among nerve energies was never rigidly disproved, the doctrine was generally abandoned in favor of the opposing view, namely, that nerve impulses are essentially homogeneous in quality and are transmitted as “common currency” throughout the nervous system.13, other experiments revealed sl
12、ight variations in the size, number, arrangement, and interconnection of the nerve cells, but as far as psychoneural correlations were concerned, the obvious similarities of these sensory fields to each other seemed much more remarkable than any of the minute differences.14, although some experiment
13、s show that, as an object becomes familiar, its internal representation becomes more holistic and the recognition process correspondingly more parallel, the weight of evidence seems to support the serial hypothesis, at least for objects that are not notably simple and familiar.15, in large part as a

26、size that could be collected in a net (net phytoplankton), a practice that over-looked the smaller phytoplankton (nannoplankton) that we now know grazers are most likely to feed on, led to a de-emphasis of the role of grazers in subsequent research. 30, studies by Hargrave and Green estimated natura
27、l community grazing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers.31, in the periods of peak zooplankton abundance, that is, in the late spring and in
28、the summer, Haney recorded maximum daily community grazing rates, for nutrient poor lakes and bog lakes, respectively, of 6.6 percent and 114 percent of daily phytoplankton production.32, the hydrologic cycle, a major topic in this science, is the complete cycle of phenomena through which water pass

Though historically there is a discernible break between Jewish law of the sovereign state of ancient Israel and of the
39、Diaspora (the dispersion of Jewish people after the conquest of Israel), the spirit of the legal matter in later parts of the Old Treatment is very close to that of the Talmud, one of the primary codification of Jewish law in the diaspora.43, Islam, on the other hand, represented a radical breakaway
40、 from the Arab paganism that preceded it; Islam law is the result of an examination, from a religious angle, of legal subject matter that was far from uniform, comprising as it did the various components of the laws of pre-Islamic Arabia and numerous legal elements taken over from the non-Arab peopl
