BIOS 135 Population Dynamics Intro This week ilab was to understand, compare, and calculate the world’s population rate. Interactive media, World Bank, CIA Factbook websites was use to gain the different elements which brought each country to its population level. Financial income plays a major role in the understanding of fertility rates, whether an increase leads to poverty or a decrease leads to a higher capital income. Procedure 1. Use the World Bank's definitions for low i...

BIOS 135 Lab Report Format for ModelChem Labs I. Title Fly Lab Week 6 iLab II. Introduction FlyLab will allow you to play the role of a research geneticist. You will use FlyLab to study important introductory principles of genetics by developing hypotheses and designing and conducting matings between fruit flies with different mutations that you have selected. Once you have examined the results of a simulated cross, you can perform a statistical test of your data by chi-square analysi...

BIOS 135 Lab Report Format for ModelChem Labs I. Title Leaf Lab Week 5 iLab II. Introduction Photosynthesis is a process that allows plants to capture the energy of light from the sun and utilizes it in order to change things like carbon dioxide and water into carbohydrates and oxygen. The following experiment will show the reactions of photosynthesis as they occur inside the tomato leaf compared to the corn leaf. The tomato leaf will perform a C-3 photosynthesis, but the corn leaf per...

BIO 135 Lab Report: Cations and anion reactions Cations and anion reactions II. Introduction • Reaction between cations and anions will be examined in this lab. The resulting precipitate is indicative of the reaction that occured. • In our lab a lead nitrate solution, Pb(NO3)2 will be mixed with a solution of potassium chromate, K2CrO4 , a yellow precipitate will forms. This precipitate must be a combination of K+ or Pb2+ cation and CrO4 2- or NO3 2- anion. Since most po...
