5)A spectroscopy would provide the different colours of the stars that make up the colour to be seen by the naked eye. It would provide the energy level that is made up in the star and would also tell astronomers what elements a certain star is made of. 6)Electrons in the Bohr theory are in perpetual motion‚ which says the electrons are constantly accelerating and decelerating. As the electrons are moving inward and outward they are moving through different energy levels‚ known as orbitals. In

three times per week. Scout the field margins in the early season and if adult beetles are detected‚ scout random locations in the center of fields. • Monitor with traps. Use cucumber beetle traps with attractive odors (pheromone traps baited with Eugenol or similar compounds‚ kairomone traps with cucurbit fruit‚ floral or root extracts) and colors (yellow sticky traps). Make sure you have traps specifically for either spotted cucumber beetle or striped cucumber beetle depending on the species of interest

Zebrafish Embryotoxicity Test (ZET) The ZET will be done following the method proposed by Beekhuijzen et al. (2015) with modifications. Six embryos will be exposed to each of the following treatments: 0.1‚ 0.05‚ 0.025‚ 0.0125‚ and 0.00625 mg/ml. Embryos will be incubated in 24-well plates with built-in lids. Each well will contain one embryo and 2 ml of the respective treatment. All test solutions will be renewed every 24h to maintain the integrity of the test concentrations. The embryos will

double bond to yield a vicinal dibromide. The next step was to perform a double elimination reaction by product gained to synthesize an alkyne‚ that is‚ 1‚2-diphenylacetylene. The two major techniques used in this lab were TLC analysis and UV-vis spectroscopy. TLC technique is non-destructive‚ that is‚ the molecules in the mixtures are separated physically without being chemically altered. Analytical TLC is used in drug analysis‚ consumer product monitoring‚ environmental pollution! studies‚ forensics

Not only did he have breakthroughs in imaging NMR‚ but in non-imaging NMR spectroscopy proving a method for the investigation of matter. Paul received many more awards during his life including the Gold Medal of the Society of Magnetic Resonance in Medicine‚ US National Medal of Technology‚ US National Medal of Science‚ and Roentgen

The objective for the experiment was to perform a reduction reaction on the ketone group of camphor to the OH group on isoborneol. In order to successfully synthesis the reactant to the product‚ NaBH4 was used as the main reagent to reduce the carbonyl double bond. One believes the formation of isoborneol was successfully due to the product’s percent yield‚ IR‚ and melting point. During the lab‚ .077 grams of isoborneol was yielded from the camphor reduction. In result‚ .077 g compared to an theoretical
