cis-elementstomatal developmenttranscriptional regulationRegulating the stomatal aperture to adapt to environmental changes is critical for plants as stomatal guard cells are responsible for gas exchange between plants and the atmosphere. We previously showed that a plant-specific DNA-binding with one ...
Which is a pure substance? (a) Element (b) Compound (c) Mixture (d) Both (a) and (b). Matter: Anything that has mass and occupies a certain amount of space can be called a matter. Classifying matter is essential to correctly attribute the properties, both physical a...
This problem is also shared when data is used to populate simulations such as crystal plasticity finite element methods [13] or FFT methods [14]. In many cases the convention with which these data are described may be sufficient, as the data is either qualitatively used (such as for grain ...
--->> 1 input the maximum displacement and with fix diagonal or non-diagonal element like this: 0.01 T F it means maximum displacement is 0.01 the diagonal element will be fixed, while random disturbing will be add to non-digaonal element --->> 0.01 T F 表示最大‘位移’为0.01,第一个...
CDefinition - Relative molecular mass is the average mass of one molecule of an element or compound on a scale on which one atom of the isotope of carbon has a mass of 12 units.A is incorrect. Relative molecular mass is a ratio. is incorrect. It should be the ratio of the average ma...
A photosensitive resin composition for forming a laser engravable printing element, comprising: (a) 100 parts by weight of a resin which is in a solid state at 20° C., wherein the resin has a number average molecular weight of from 5,000 to 300,000, (b) 5 to 200 parts by weight ...
Recently a new class of semiconductors has emerged, whose fundamental properties are dramatically modified through the substitution of a relatively small fraction of host atoms with an element of very different electronegativity, the so called highly mismatched alloys (HMAs). III-V alloys in which gro...
