8 Salloum 1 Key Issue 3: Why is Popular Culture Widely Distributed? Popular culture varies more in time than in place. Popular culture begins in one location, like folk culture, but diffuses rapidly across earth to locations with a variety of physical conditions. Rapid diffusion depends on a group of people having high level of economic development. Diffusion of Popular Housing, Clothing, and Food Some regional differences in food, clothing and shelter continue to persist in MDCs. Popular Housing Styles Housing built in the U.S. since the 1940s demonstrates how popular customs vary more in time than in place. Newer housing in the U.S. has been built to reflect changing fashion of houses. After WWII, most U.S. homes were built in modern style.

Analyses Osmosis and Diffusion Osmosis and Diffusion are processes of passive transport. In this lab we studied the basic concepts of molecular movement in solutions. During the execution of the experiment, I became aware that molecules are in constant motion and tend to move from areas of higher concentration to those of lower concentration. Diffusion is the movement of molecules following that concentration gradient. It occurs on the diverse states of matter. Osmosis refers to the specialized diffusion of molecules of water through a selectively permeable membrane.

AP Biology James Pre-Lab: Diffusion and Osmosis in Model Systems In parts 1 and 2 of this lab, you will have the opportunity to investigate the processes of diffusion and osmosis in model membrane systems. You will also investigate the effect of solute concentration on water potential as it relates to living plant tissues. Objectives: At the completion of this AP laboratory, you should be able to: Describe the mechanisms of diffusion and osmosis. Describe how solute size and molar concentration affect the process of diffusion through a selectively-permeable membrane. Describe the relationship between solutions that are hypotonic, hypertonic, or isotonic. Design an experiment to demonstrate water potential.

Toponymy: DEFINITION: Classification of Place Names: Provide a definition and example for each one. Descriptive: Toponym that derives from physical features Associative: toponym- Example- mill river (mill on the river) Incident: Ex battle creek (toponym) Possessive: named for a person, perhaps founder Commemorative: commemorating someone well known (washington dc) Commendatory: praising names like ones that lured pioneers to the american west (pleasant valley) Folk-Etymology: a false meaning extracted from a name based on its structure when being named Manufactured: names that are made up like tesnus(sunset spelled backwards) Mistake: historical errors in identification when naming (west indies) Shift
