    Notes: [Auszug] ARE bacteria a class of plants, Schizomycetes, distinguished by the fact that they reproduce exclusively by simple fission, or are they not ? The name has one virtue, one of the two allowed by Mortimer Batten to the song of the kingfisher: nobody hears it. Because nobody, including the authors of ...

    Notes: [Auszug] A SURVEY taken by the Audience Research Department of the B.B.C. showed that, despite developments in the teaching of biology in secondary schools, few members of the general public have much accurate knowledge of the theories of evolution and the facts upon which they are based. What better ...

    Notes: [Auszug] These mid-water squid had enormous body cavities filled with fluid1. When the fluid, and it amounted to two-thirds of the squid s volume, was drained the squid sank; this showed that the buoyancy of the intact animals was given by the low densities of their coelomic fluids. From the volumes of ...

    Notes: [Auszug] Blood-sugar measurements were made using the modified method of Shaffer and Hartmann5 in the blood of the ear artery of rabbits. It was found that 5 hydroxytryptophan given intravenously in small doses (5 20 mgm./kgm.) definitely raised the blood-sugar level. Fig. 1 shows the blood-sugar rise after ...

    Notes: [Auszug] The quantitative assessment of mitochondrial clumping is not easy. We tried various indices, for example the ratio of total clumps (including single mitochondria) to total mitochondria, or the number of mitochondria in the largest clump in a field. Finally, we made a scale consisting of nine ...

    Notes: [Auszug] In 1950 L ns2, basing his argument on antigenic individuality of human red cells, proposed the method of determining paternity by the use of polyvalent immune serum. He assumed that the polyvalent serum absorbed by the red cells of the father and the mother would react with the red cells of all ...
