The discipline of archaeology is by no means a simple nor singular study of the past. Due to the wide range of evidence within the archaeological record‚ from organic to inorganic‚ many different methods and approaches are taken in order to deal with the wide spectrum of differing evidence. Nevertheless‚ the study of pottery is without doubt one of the most important tasks taken on by any archaeologist. A great wealth of information can be gained from the study of pottery‚ despite its inanimate state

Score 1. How do you calculate magnification on a microscope? Answer: The shortest lens is the scanning objective; you use it to locate the object on the slide. The medium-length lens is the low-power objective. The longest lens is the high-power objective. Multiplying the power of the eyepiece lens and the nose piece lens gives you the total number of times an object will magnified. (4 points) Score 2. Explain how to focus a microscope using the high power lens. Include any safety issues

instruments such as microscope‚ staining‚ stethoscope and X-rays. Of the five senses‚ the most important is sight. It aids in the process of gathering information about the environment that we are part of. However‚ this visual gathering is adequate only to a certain point. Beyond this point‚ the unaided human eye fails to help us; the amount of detail that it can provide is severely limited. In order to overcome this limitation‚ humans started to develop instruments like microscope. The development

It is often used in measurements of the electron transport chain in plants because of its higher affinity for electrons than ferredoxin. It is also used as an artificial electron acceptor for enzyme assays. ( ) A Hill Reaction is used to measure the rate of photosynthetic electron transport.
