1. For electromagnetic radiation with a wavelength of 559.9 nm: (a) What is the frequency of the radiation (in s-1)? (b) What is the energy (in J) of one photon of the radiation? (c) What is the energy (in kJ) of one mole of photons of the radiation?
2. Hydrogen atoms absorb energy so that electrons can be excited to the n = 5 energy level. Electrons then undergo these transitions, among others: (a) n = 5 → n = 4 (b) n = 5 → n = 3 (c) n = 4 → n = 2 (i) Which transition produces a photon with the least energy? (ii) Which transition produces a photon with the highest frequency? (iii) Which transition produces a photon with the shortest wavelength?
3. An atom of some element X has three electronic transitions, A, B, and C. Suppose that it has been found that the wavelength for transition A is 495.1 nm and that for B is 602.2 nm. (a) What is the energy (in J) for a photon given off in transition C? (b) What is the wavelength (in nm) for transition C?
It is a very curcial concept to understand how the immune response is mounted against viruses, bacteria, protozoans and helminthes. For an effective immune response, both innate and adaptive immunity should work together.
This Project report elaborates a critical review of important elements attached to Advanced Glycated End Products (AGEs). It is very crucial to understand the process called Millard reaction.
Soil stabilization is the permanent physical and chemical alteration of soils to enhance their physical properties. Stabilization can increase the shear strength of a soil and control the shrink-swell properties.
This assignment has three parts which contains questions related to Microbiology. It contains basic principles of microscopy, staining techniques in microbiology and microbial growth in the food industry.
Lipid metabolites are often seen as key elements in cellular signaling. Is this unique? Please provide several examples of the function of lipids as key elements in signal arrays and list the biologic functions these signals affect?
Please describe how one might search for chemical structure, biologic function relationships, involving small molecular weight lipophylic compounds. Provide one example.
