Carbohydrates have a general formula CH2O, while fats typically have a general formula of C10H19O. Which of these classes of foods has greater oxygen content as a percentage of molecular mass? Which of these will release more energy when metabolized? Expl ...

aYou had better go to see a doctor 您应该去看医生[translate] aGenerally,atoms on the surface are bonded more weakly than atoms in the bulk material which have a higher coordination number. 通常,原子在表面在粒状材料更加微弱地比有一个更高的协调数字的原子被结合。[translate]...
The protein structures were pretreated: hydrogen atoms were fixed and cocrystallized ligands and water molecules in protein-ligand complexes were removed. Finally, we used Cytoscape 3.2.0 to build a 'component-target-disease' interaction network. To clarify the in vivo pathways involved in the ...

The device (1) for determining and acting on free electrons, atoms and ions, in particular, alkalis in gaseous media comprises one or more electrically conductive probes (4) which are surrounded by different materials, as well as by a ceramic cover (8). This cover can be made selectively ...
It is at all events matter for argument whether theism cannot offer a more promising solu- tion of the problem of value than the optimism which pins its faith to the evolutionary process. But this is a view which, I fear, would scarcely find favour among those who collaborated in this ...
8.This would explain why isotopes can smell different: their vibration frequencies are changed if the atoms are heavier.Turin's mechanism, says Marshall Stoneham of the UCL team, is more like swipe-card identification than a key fitting a lock. 9.Vibration-assisted electron tunnelling can undou...
Nowadays, scientists still use microscopes that use light to see small objects such as cells and micro-organisms.5. These electron microscopes have a magnification(放大) of a million times and now we can see molecules(分子)and atoms.
