Investigation and Preparation of Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other.

Regents Biology Period _________ Date ______________________ LAB ____. ANATOMICAL EVIDENCE OF EVOLUTION In our studies of the anatomy and development of animals we have discovered that many living creatures that look quite different on the surface have similarities underneath their skin that suggest that they are related to each other. This is evidence that living creatures have evolved‚ or gradually changed over time. In this lab‚ you will learn about homologous‚ analogous‚ and vestigial structures

Lab 6 Experiment 2 1. It is important that bass caught and marked are returned to the lake unharmed because if they are harmed them they are less likely to be caught again or they may end up dying if they are returned harmed. 2. I don’t this type of population would be easier to count directly because I don’t think it would be possible to catch all of the bass in the population to conduct this experiment. 3. I think that sample size is relative to population density and will positively

rate change over time? How does this compare to a real enzyme? The enzyme’s rate did change over time. This compares to a real enzyme because an enzyme’s job is to speed up the reactions and as time allotted. That did happen since the enzyme in our lab was able to make more chainobeads as time progressed. 4. Graph 5.

Chapter 9 THE FIXED PRICE KEYNESIAN MODEL The Keynesian Critique of the Classical Model Wages‚ prices and interest may be “sticky‚” or inflexible‚ so that markets may not always clear. The classical model assumed that wages were flexible enough so that labor markets always cleared; the price level was flexible enough so the product market always cleared; and real interest rates were flexible enough so that saving is always equal to investment so that the loanable funds markets cleared.

1. Compare the hash values calculated for example.txt that you documented during this lab. Explain in your own words why the hash values will change when the data is modified. They change to keep authentication and integrity. 2. Why are the MD5sum and SHA1sum hash values the same every time you calculate for the “example.txt” sample fi le? What if they were different when you re-calculated the hash value at the other end? These are the same to verify authentication and integrity.
