In the chemical reactor there's a vacuum very close to that of interstellar space. And the temperature is minus 200° Celsius.在化学反应堆中有一个非常接近星际空间的真空空间。温度是- 200摄氏度。We made the ice, we can see a bit here, a sort of growth on the edge of the window. The ...
the hologenome concept has been put forth to describe the evolutionary unit formed by the genome of an organism and its microbiome (Zilber-Rosenberg and Rosenberg, 2008, Bordenstein and Theis, 2015, Moran and Sloan, 2015, Douglas and Werren, 2016, Theis et al., 2016, Roughgarden et al.,...

This membranous mat is embedded with spicules and a series of interconnected canals used for nutrient flow and water movement throughout the organism. The polyps are embedded in this surface as well. On many Octocorals the polyps may be housed within little bumps raised up on the surface, ...
Bacteria are the pioneer of life forms in barren lands like deserts, rocks, etc. Every living organism living today are evolved from some eukaryotes which were developed from bacteria some 2.0 billion years ago. Bacteria are present as normal flora in our body. They help fight against invading...
