It is no secret that bottled water costs more than tap water‚ but is it reasonable to state it costs 1‚000 times more? It is very difficult to give an exact number for the difference between the two‚ but 1‚000 to 2‚000 times more is a reasonable estimate. This is based on the fact that on average‚ a gallon of bottled water costs $1.22. Protesters against bottled water industries use the highest prices of water bottles they can find as a way to show a bigger contrast between the two‚ essentially

Labs 4 & 5 Lab Four: Experiment 1 1. At what magnification do you first notice the ragweed pollen? I first noticed it when the magnification is at about 30 2. Which is bigger‚ rhinovirus or E. Coli? E. Coli is bigger 3. Based on the magnification‚ how many of the E. Coli can fit into the same space as the head of a pin? 10‚000 E. Coli 4. About how many red blood cells could fit across the diameter of a human hair. (Again‚ look at the magnification scale)? About 100 blood cells

Name: Mugabe Rodrigue Class: Grade 11B Subject: Biology Topic: DNA Extraction From Onion Date: 20/1/2014 Introduction: DNA‚ or deoxyribonucleic acid‚ is the hereditary material in organisms. Nearly every cell in an organism has the same DNA. Most DNA is located in the cell nucleus.The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of these bases determines the information available for

According to the data‚ the population size obtained for Group RG/CL is an outlier in respect to other groups’ population sizes. After two weeks of sampling and counting the population of mealworms‚ a population of 506 mealworms was calculated. A very broad confidence interval was also calculated‚ ranging from 143.58 to 868.42 (Table 1). Although other groups seem to have large confidence intervals‚ they are within a 200-300 limit. The confidence interval calculated for Group RG/CL has about a 700

Mailbox #55 Affects of Osmosis and Diffusion Introduction: Perfume spreads in a room‚ hands bloat when left in water for too long (shriveling is a common misconception)‚ a tea bag’s contents diffuse through the water. These are all examples of diffusion and osmosis. These phenomena happen everyday and people don’t realize what is actually happening. The purpose of the lab is to see the effects of diffusion and osmosis. In part B‚ the higher the concentration of solute‚ the higher the mass
