Explain how x-rays are produced when an electron beam falls on a metal target. Explain how viruses reproduce. Explain what happens in photosynthesis. Describe how sulphuric acid is produced in the atmosphere. Define a catalyst and explain how a catalyst was discovered?
Pathways on the left are dominated by female-biased genes. Pathways on the right are dominated by male-biased genes. Gene abbreviations:Aao, abscisic-aldehyde oxidase;Aba2, xanthoxin dehydrogenase;Atdvr, divinyl chlorophyllide an 8-vinyl-reductase;C4 h, trans-cinnamate 4-monooxygenase;Cad, cinnamyl...
Explain how infrared radiation can travel the length of an optical fiber. Describe and explain applications of this. Infrared Radiation: In physics and engineering, infrared radiation refers to a type of radiation with a certain frequency or wavelength. Infrar...
In this study, we sought to better understand how the actomyosin machinery gives rise to such a diverse array of gliding movements and, more broadly, how actin and myosin are patterned or polarized to yield coherent force generation in this system. Tracking actin and myosin in motile Toxoplasma...
Study of shock wave dynamics produced by interaction of a fireball with the surrounding medium to it, to explain the x-ray afterglow of Gamma Ray Burst-GRBsThe Gamma-Ray Bursts - GRBs are one of the most energetic astronomical events in the universe that have not yet an adequate ...
How a scanning electron microscope (SEM) works A scanning electron microscope scans a beam of electrons over a specimen to produce a magnified image of an object. That's completely different from a TEM, where the beam of electrons goes right through the specimen. Electrons are fired into the...
A collaborative team of researchers from Argonne's Advanced Photon Source (APS), Midwestern University and Arizona State University wanted to study how beetles' tracheal systems change as their body sizes increase. The team took advantage of richly detailed X-ray images they produced at the APS to...
Describe the two types of metamorphic texture, and discuss how they are produced. What are the different theories of light? Explain the sun's structure. List and describe at least four terms that can describe the nature of a variable. Define a ray of light. Explain why Light travels faster...
to a point where it can even be used as an x-ray. Phosphors, not to be confused with the elementPhosphorus, are substances that glow when exposed to some other, typically more energetic, form of radiation, and can be used to produce a desired glowing effect by taking less useful parts ...
a) Define sensation and perception; explain the difference between the two terms. b) Describe signal detection theory. c) Define sensory adaptation. How are sensitization and desensitization different? What will be an ideal response...
