Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Instructions for AP BIOLOGY Investigation 12-Fruit Fly Behavior *We will be using Roly-polies (Armadillidium vulgare) to study animal behavior instead of fruit flies. They are members of a family of woodlice in the order Isopoda that are able to roll into a ball. When writing up this lab‚ substitute A. vulgare or “roly-poly” or “pillbug” for Drosophila melanogaster throughout. **You still have to know the basics of fruit fly behavior‚ so be sure to read the lab carefully and save the lab handout to

Chapter 1 Reading and Study Guide Why This Chapter Matters 1. We are living in the golden age of biology. Biological discoveries revolutionize medicine‚ change agriculture‚ and impact human culture. 2. Life is united not by a single trait‚ but by a common set of characteristics. Appreciating what it means to be living is as complex as life itself. 3. Life exists at many levels of biological organization. Understanding how these levels interrelate provides insight into the mechanisms of living systems

While being white was the norm‚ at that time biology was important and science was influencing the population. Indeed‚ there were‚ are and will be physical differences between people. Yet‚ what is significant about these when it comes to race is not the biology of those differences‚ but the social weight we attach to them. Therefore‚ the race still exists not because it is biological or normal‚ but because
