Change in the color of litmus from purple to pink or pink-red throughout the tube. Upon further incubation a white ring of litmus forms at the bottom of the tube at the pink-red color is now present only at the top of the tube. Still further incubation leads to the formation of a rennet curd at the bottom of the

Environmental Systems Bio-cylinder Lab Report Planning: The question that we‚ as a class‚ were trying to answer was: How long can the organisms survive within a sample-closed ecosystem? To answer this three separate classes had the opportunity to create their own bio-cylinders‚ place a specified number of organisms‚ seal it‚ and observe the cylinder for however long the organisms were able to survive. Each class made small modifications to the number of fish and snails that placed within the

Patel Chem 101 10-13-09 Introduction The objective of this lab was to show how stoichiometry is applied to a specific chemical reaction. Stoichiometry is pretty much the math behind chemistry. Doing stoichiometry can calculate masses‚ moles‚ and percents with a chemical equation. The use of stoichiometry is how we were able to find the limiting reagent in this lab. A limiting reagent is the chemical that will be used up first. Many calculations had to be made throughout this lab. Some of

In the “Crush the Can” lab‚ we took an aluminum can‚ heated up some water in it‚ and turned it upside down into a tub of ice-cold water‚ crushing it with pressure. The movement of gas particles was a crucial component of this experiment. After the can was placed onto the hot plate‚ as the water heated up‚ the gas particles inside of the can started to move faster due to the relationship between temperature and the average kinetic energy‚ or average motion energy‚ of the gas particles. As the temperature

What Does The Evidence Reveal About The Death Of Otzi The Iceman? Advances in technology and scientific method over the last 25 years have provided new evidence which disproves the original theory that Otzi‚ the iceman‚ may have fallen‚ injured himself and died from hyperthermia. High resolution CT scanning as well as new scientific techniques which allow for the analysis of blood‚ tissue and DNA have resulted in entirely different evidence-based theories. Evidence now suggests that Otzi died violently

In the BIO 14 Lab‚ the organismal system used for the last of three labs this semester is the Mimosa pudica plant. In these three weeks the stimulus-response of these plants will used to conduct experiments on the phenotypic plasticity of Mimosa pudica. Phenotypic plasticity is the ability of an organism to change its phenotypic traits in response to changes in the environment. And while very beneficial in some ways such as by allowing organisms to adapt to a changing environment quickly‚ it also
