| the order of death of organisms larger than bacteria. | in a previous paper it has been shown that the logarithmic order of death of bacteria can be accounted for by the assumption of some very unstable molecules so essential for reproduction that the inactivation of only one such molecule per cell prevents reproduction and makes the cell appear "dead" according to the standard method of counting living bacteria. in the present paper dealing with the order of death of larger organisms, only a motile alga, chlamydomonas, is shown to have the same orde ... | 1931 | 19872588 |
