2. What is the dynamic range problem and how does it affect the efficiency of a chromatographic analysis?
what is the dynamic range for an instrument? how is it related to a calibration curve?
The ionization potential of a hydrogen atom is 13.6 eV. How does this compare to the energy of a typical particle at the recombination epoch, when the temperature of the universe was 3000 K. How does that compare to the energy of photons at the peak of the Planck function at that time? What can you conclude from these comparisons?
Explain what a neuron's dynamic range is and why it is important for neural function and coding. Include in your answer the advantages and disadvantages for large and small dynamic ranges How does the neurotransmitter bind to the postsynaptic membrane/receptor and what happens to the postsynaptic neuron? Explain in the most detail that you can Explain how neurons can encode the intensity of a stimulus and how neurons can preferentially respond to changes in the environment

1. In general, compare the Static data model, to the Dynamic data model, to the Normalized data model. 2. What does the Dynamic data model add? (behavior classes, communication diagrams) 3. What does the Normalized Data Model add or change (association classes, FK, attributes)?
2- ECD 3- ICP-AES 4- TCD 5- AAS 6- GLC 7- SHE 8- SEC Q4- What kind of chromatography wil be most applicable to separate the following substances: (choose from the following: gas- liquid chromatography, liquid-solid partition chromatography, reversed phase partition chromatography, adsorption chromatography, ion-exchange chromatography, gel filtration chromatography, gel permeation chromatography) (3.5 points) Chromatographic separation technique Mixture a- Gasoline fuel components (mostly a mixture of aliphatic hydrocarbon compounds) b- Free amino acids (*NH3-CHR-COO) (Analine, Leucine, Valine, aspartic acid, Glycine...
Describe the mass, radius, and thus density of a typical white dwarf star. How does this compare to the density of water? What kind of pressure is used by a white dwarf to oppose its strong gravity? How does a white dwarf’s radius depend on its mass, and how does this set the maximum mass of a white dwarf?
