6. The ph solutions that were used were 2‚4‚7‚9 and 10. All of these solutions affected the beetroot‚ but the most acidic solutions were the ones that did the most damage to the membrane. This is because the ph affects the proteins within the phospho lipid bi-layer. The acidic ph breaks the hydrogen bonds therefore denaturing the proteins and allowing beetroot pigment to secrete form the cell. 7. The ethanol solutions that were used were 11%‚ 25% and 50% ethanol. The beetroot cell was almost immediately

Chapter 5: Cost Behavior: Analysis and Use As we shall see in later chapters‚ the ability to predict how costs respond to changes in activity is critical for making decisions‚ controlling operations‚ and evaluating performance. Three major classifications of costs were discussed in this chapter—variable‚ fixed‚ and mixed. Mixed costs consist of variable and fixed elements and can be expressed in equation form as Y = a + bX‚ where X is the activity‚ Y is the cost‚ a is the fixed cost element‚ and

used to help determine the concentration of an unknown solution (the analyte) by using a solution of known concentration (the titrant).1 In medicine‚ titration helps doctors determine unknown concentrations of substances in the blood or urine‚ and it is useful in determining the proper dosage of medication. Titration can determine fat and water contents‚ and unknown concentrations of vitamins. With food‚ titration can be used to determine whether cheese or wine is adequately aged for delivery.2 The
