Regents Biology Period _________ Date ______________________ LAB ____. ANATOMICAL EVIDENCE OF EVOLUTION In our studies of the anatomy and development of animals we have discovered that many living creatures that look quite different on the surface have similarities underneath their skin that suggest that they are related to each other. This is evidence that living creatures have evolved‚ or gradually changed over time. In this lab‚ you will learn about homologous‚ analogous‚ and vestigial structures

Chapter 4 In Howard Zinn’s book‚ Passionate Declaration: Essays on War and Justice‚ I read chapter four titled “The Use and Abuse of History.” Zinn in this chapter discusses how history is used and abused. Many in society today only tell “impartial history‚” meaning we leave parts of history out to make a certain group or event stick out. History in the United States of America is swayed always to make us look like the good ones. We are a biased country and the government will do anything to censor

PHOTOSYNTHESIS LAB Alyssa Wright VARIABLE: LIGHT INTENSITY AIM: to investigate the effect of light intensity (lux) on the amount of oxygen produced (number of bubbles) HYPOTHESIS: I predict that the rate of oxygen produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen

Post-Lab Questions 1. Using the information provided in the Introduction and your observations from Part 1‚ hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint. a. Aqueous Sodium Hydroxide—NaOH (aq) is a very strong base‚ which will completely disassociate into Na+ and OH- ions‚ which would make it a very strong electrolyte. Chemical reaction of the disassociation of Sodium Hydroxide: NaOH (aq)Na+ (aq)+ OH-(aq)
