Scientists now think that a large proportion of these molecules came from outside planet Earth. Comets and asteroids could be the missing links of a long chain.科学家们现在认为，这些分子中有很大一部分来自地球以外的星球。彗星和小行星可能是生命的长链中缺失的环节。The chain began with the simple ...
There is great diversity of cell types in the cereal shoot, forming an equally diverse set of tissues. This can be shown anatomically as well as functionally and biochemically. Since this diversity was not considered in the original Cholodny-Went hypothesis for plant tropism, it has been ...
