introduction of the microscope as a tool for the biologist brought about a complete reappraisal of the micro- composition of biological tissues‚ organisms and cells. In the infancy of its application to organic materials‚ it was the implement of anatomists and histologists in particular‚ where previously unimagined structures in cells were revealed. More recent developments in biological specimen preparation have come from biochemists and physicists who have used the microscope to examine cells and

Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a

My Life under the Microscope SOCS 185 The older I grow the more everything in my past seems to make sense in relation to the person I am today. The trials and tribulations my family and I experienced have shaped and become the definition of this thing called “life”. I’m pretty clear about whom I am as a person‚ but now that I know different sociological concepts and perspectives‚ I’m interested on how society views me as a person. I will attempt to explore the sociological concepts I’ve learned

Identification of a Copper Compound by Percent Mass Unknown Compound: #9 Abstract: The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this‚ the mass of copper in the unknown was calculated and then divided by the mass of the whole compound to get the percent copper. The molecular weight was also calculated by dividing mass of copper compound used by moles of compound in unknown sample. The percent copper averaged out to 31.6% while the molecular

The Branch Davidian Compound was established as living-worship center for the members of the sect to reside. The residents of the compound lived‚ worked‚ learned‚ and worshipped in the isolated community. Because of the nature of the isolation and basis of the belief system of the Branch Davidian church created a unique way of life for the residents. Life in the compound was mostly dictated by David Koresh because he was a self-proclaimed messiah (equip.org) in which the members followed. Because

Organic Chemistry/Biochemistry 1: Compounds Important to Life • Biologists classify compounds into organic compounds and inorganic compounds. Organic Compound: a compound that is derived from living things and contains carbon Inorganic Compound: a compound generally derived nonliving things • Water Water is an inorganic molecule with unique properties that make it one of the most important compounds for living things. In the water molecule (H2O)‚ the hydrogen and oxygen atoms bond
