this display of various preserved species in the archaeological and natural history museum in berlin has used a palette of substances and dyes that will change in color over time. how long can you identify each? (a) silk (cotton-like fiber), (b) cotton, (c) wool, (d) hair fiber, (e) feathers, (f) velvet, (g) silk, (h) wool, (i) cotton, (j) silk, (k) cotton, (l) wool, (m) hair fiber, (n) feathers, (o) velvet. the best ink for tracing linear text is a pen containing natural pigments that fade in a day or two. tattoo inks are permanent, and abrasive or metallic inks will not erase. a black brush is best for hand writing, and a black and white pen is good for lettering.
geologists have been using a wide variety of specimens, including fossils, rocks, soils, surface materials, and sediments, to form their interpretations. geologists generally do not use a single specimen, but a group of similar specimens, all collected from the same environment. the geologist may use tools to extract these specimens. a hand drill is an example of such a tool.
geologists generally record their findings in the form of rock specimens, fossils, and soil profiles. the data recorded by geologists will vary in terms of the purpose, quantity, organization, and richness of information that is captured. thus, data collection varies depending on the purpose of the work being undertaken by the geologists.
stable isotopes of carbon (13c) and oxygen (18o) in the plant canopy and leaves of a plant reflect the plant assimilating atmospheric 13co2 and 18o2 via photosynthesis and respiration. just as in living organisms, the concentration of these isotopes in plant biomass depends on the balance between primary production and respiration. different plant species use different sources of carbon and carbon isotope composition for photosynthesis, and the isotope fractionation that occurs during respiration can vary significantly depending on species. the isotopic ratio of the plant canopy to surface soil can provide information on the strength of the net primary production versus respiration, and the relative contribution of different species to the local ecosystem.
in material science, the term density usually refers to the mass of a volume divided by its volume. density can therefore be thought of as a mass per volume of a material. however, the density of matter also has another meaning: for a given mass of matter, what is the maximum volume (called macroscopic volume in this book) for which this mass of matter will fill out? this is a quantity called the “gross density” of the material, and is usually denoted ρ.
the definition of the term “crystallization” is not necessarily well understood. therefore, the book has also analyzed the phase transition processes and the hydrophobic effects influencing the crystallization of lipids in the presence of water and how these processes are used for their controlled production in the fields of pharmaceutical, food and cosmetic. this chapter thus focuses on the structure of water, its properties, phases and the coexistence of water with organic and inorganic compounds as well as in the nanometric scale. the book then moves on to what is known as the functional groups of molecules and groups of atoms constituting organic materials. the book concludes by describing electron transfer processes in biology, how proteins are made and how they carry out their functions in biological processes.
the drawing depicts the secretion pathway from the endoplasmic reticulum (er) to the golgi apparatus. while the secretory pathway in yeast appears to be very simple, more complex is the case in multicellular eukaryotes. in addition to the above-mentioned hormone synthesis in the liver, the human body produces a plethora of chemicals: these include the well-known neurotransmitters and hormones, but also, in addition, the human body produces countless others, all destined to pass through this route.
