A water molecule consists of two hydrogen atoms attached to a single, larger oxygen atom. The angle between the two hydrogen atoms is 120 degrees--the same angle as the angles of a hexagon--which accounts for the characteristic six-sided structure of ice crystals. The phrase accounts for in...
aWater molecules consisting of H2O are small enough and get into the root. Nitrate is also a small molecule, NO3, and it is also absorbed into the root. Other nutrients such as phosphorous, potassium, iron, magnesium etc are all small enough to enter the roots 包括H2O的水分子是足够小的并...
A water molecule consists of an oxygen atom with two hydrogen atoms bound to it(see the figure below).The angle between the two bonds is106\deg.If the bonds are l=0.100nm long, where is the center of mass of the molecule?(...

By optical, ESR and ENDOR measurements the [H 2O -] s center in KC1, produced by photochemical reaction from [OH -] s, is identified as an F center with a water molecule trapped at <111> off-center sites. Above 30°K motional narrowing gives an ENDOR spectrum of cubic symmetry....
(Fig.4b)32. In contrast to the structure ofHbRC53, we did not find a water molecule as an axial ligand to the Mg(II) of A0; instead, we found two phosphatidyl glycerol (PG) lipids interacting with the A0pair within the PscA dimer (Fig.4c). These PG lipids also fit the un...
Here a prominent hydrogen evolution reaction (HER) of single water molecule on vanadium clusters Vn+ (3 ≤ n ≤ 30) is observed in the reaction of cationic vanadium clusters with water at room temperature. The combined experimental and theoretical studies reveal that the wagging ...
This DNA molecule has to be folded to fit in the protein coat. Which statements about single-stranded DNA are correct? 1 Single-stranded DNA cannot replicate semi-conservatively. 2 If only the percentage of cytosine is known, then the percentage of guanine can be calculated, but the ...
Serine-based β-lactamases of Class A, C and D all rely on a key water molecule to hydrolyze and inactivate β-lactam antibiotics. This process involves two conserved catalytic steps. In the first acylation step, the β-lactam antibiotic forms an acyl-enzyme intermediate (ES*) with the catal...
