INTRODUCTION Iodine deficiency disorders are still very much prevalent in the world today. Two billion people‚ estimated by the WHO‚ still lack a sufficient level of iodine in their diets which leads to a range of disorders known as iodine deficiency disorders (IDD). So what is iodine? Iodine is an essential micronutrient in the diet which is used by the thyroid gland (located in the throat) to produce thyroid hormones which help control the body’s metabolism. The two most important thyroid

Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of the potato after being

I will be measuring and controlling many different variables‚ these include; - The dependent Variable Weight of potato chip Independent Variable Concentration of sucrose Control Variables consist of; - 1. Temperature 2. Surface area of potato 3. Volume of sucrose solution 4. Same

I recently wrote an essay about the development of the star persona of Ice Cube‚ the rapper/actor who has made the unusual transition from hardcore gangsta rapper to leading man in such “family-friendly” films as Are We There Yet? The essay‚ entitled “With an Attitude: The Development of Ice Cube’s Star Persona‚” will soon be published in the online film journal 16:9; I’ll link to it as soon as it’s up. The thesis of the essay is that‚ for all the apparent and unexpected alterations to his “street”

Diffusion In Agar Cubes Is Bigger Better? OR Is Smaller Smarter? Adapted from Flinn Scientific Publication No. 10110 Introduction: Diffusion is one of the very important processes by which substances such as nutrients‚ water‚ oxygen‚ and cellular wasted are transported between living cells and their environment. This activity will help you explore the relationship between diffusion and cell size by experimenting with model “cells.” In this experiment‚ you will use agar cubes to which the

Research Project: Potato The potato originated in the South American Andes‚ but its heartland of wild genetic diversity reaches from Venezuela‚ Colombia‚ Ecuador‚ Peru‚ Bolivia‚ Argentina‚ Chile‚ Uruguay‚ Paraguay‚ southern Brazil‚ northward into Central America‚ Mexico‚ and the southwestern United States. Potato was first cultivated between 3 and 7 thousand years ago‚ some scientists believe they may have grown wild in the region as long as 13‚000 years ago. Potato is the third most important
