As previously mentioned, a cell's cytoplasm is home to numerous functional and structural elements. These elements exist in the form of molecules and organelles — picture them as the tools, appliances, and inner rooms of the cell. Major classes of intracellular organic molecules include nucleic ...
Hope and love are popular themes of literature and art in many human societies. The human physiology of love and hope is less well understood. This review presents evidence that the lack of love and/or hope delays growth disturbs development and maturati
In that sense, Earth is probably unique. Although we may detect some life elsewhere, it will necessarily be completely different.从这个意义上说，地球可能是独一无二的。虽然我们可能会在其他地方发现一些生命，但那肯定是完全不同的。It was this mind-blowing series of improbable events that made Earth...
