150mL test tube. Cover, invert tube twice and put tube in the rack. Start timing the reaction promptly. 5. Over a 5-minute period observe any colour changes while being sure to rotate the tube before reading it. Record observations at 1 minute intervals 6. Reference the colour chart on page 156 of the AP Biology Investigation Labs book to compare colour progression. 7. Repeat steps 1- 4 again. After combining the enzyme and the substrate together, quickly and meticulously pipette the solution…

ancient human remains. It is very precise and accurate and is therefore used for a range of biological specimens as well (Mason, 2017). An American scientist called Willard Frank Libby first perceived the basis of a dating method supported by the prediction of the existence…

Until recently it was believed that the earth had only experienced 4 to 5 glacial periods, all of which occurred in the past 2 million years. (Louis Agassiz, 1837) However, globally conducted research has revealed that countless glacial advances have appeared over 200 million years ago, thus broadening our insight of the history of the earth system by 100 times. These astonishing advances have witnessed the introduction of a new sub-discipline—palaeoclimatology, which specialises in the study of…

Student success is defined as a student who has received a final GPA in the class of a 3.0. Student success is defined by the student’s ability to master tasks associated with presented information as well as recount the skills at different intervals during the particular school year and beyond. Success is also defined by the student’s ability to participate as a hardworking, productive member of society. We measured student success using the GPA scale. We are able to compare the GPAs of…

Edwin Gordon is one of the several influential educators in the music education field. Gordon is well known as a researcher, educator, and creator of the music learning theory. He has also made important contributions to the field of music education by creating music aptitude testing that can be used in the classroom for all ages. Gordon began is education career as a string bass performance major at Eastman School of Music where he received his bachelor’s and master’s degrees. After graduating…

The title of the test in review is the Test of Nonverbal Intelligence, Fourth Edition, also known as the TONI-4. Linda Brown, Rita J. Sherbenou and Susan K. Johnsen originally wrote the test. The test is currently published by PRO-ED, which is located at 8700 Shoal Creek Boulevard in Austin, Texas. The company’s website is www.proedinc.com. It is recommended that the testing process take approximately 15 minutes, although, there is no specific time limit for test takers to respond during the…

The purpose of this experiment is to determine the rate of Escherichia coli (E. coli) growth over 100 minutes in a liquid growth medium (control), and to determine the rate of E. coli growth over 100 minutes in a heated liquid growth medium. The prediction is that the control E. coli culture will grow at a faster rate exponentially over 100 minutes than the experimental bacteria culture. Consequently due to heat application, the experimental bacteria will not grow over the 100 minutes, and will…

Imprecision The lowest coefficients of variation for precision within and between series over the whole tested concentration range were found for the LIAISON CLIA and LC-MS/MS method. Then followed the RIA. The Immulite CLIA showed the highest overall values and thus the lowest precision. A detailed list of all calculated variation coefficients is provided in Table 1 (A). Sensitivity The limit of blank (LoB), limit of detection (LoD) and limit of quantification (LoQ) were determined for all…

weeks after the accident and again one year after and were requested to recall the disaster. The results found overall only 3% of participants formed FBMs. Although this accident was surprising, personally significant and a public event, the authors prediction that it would result in a highly emotional response and thus trigger FBMs was…

fracture is predominantly a phenomenon of later life, and 80% are female (Handoll, Camerson, Mak, & Finnegan, 2009). An estimated 1.26 million hip fractures occurred in adults in 1990. With the projected increase in population over 65 years of age, predictions range from 7.3, to 21.3…
