Biochemistry is the chemistry of biological systems. The practical component of biochemistry is aimed at developing your interest in and understanding modern biochemical and molecular biological experimentation. The techniques learnt in the biochemistry lab will be applicable to all life sciences. THE OBJECTIVES OF THE BIOCHEMISTRY LABORATORY INCLUDE: (1) Learning the theory behind the techniques and biochemical pathways (2) Learning the physical skills and techniques of modern experimental biochemistry

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

Academic Dishonesty Academic Dishonesty “To cheat or not to cheat‚ that is the question.” This modified statement‚ borrowed from the soliloquy in Shakespeare’s Hamlet‚ aptly denotes the ethical dilemma faced by all students. The majority of students endeavor to conduct themselves in an upright manner. Yet the harsh reality is that many learning institutions‚ from high schools to universities‚ are becoming rife with academic dishonesty. The advent of technology has created a tantalizing

breathing. 8. Describe some possible causes of respiratory alkalosis. ACTIVITY 2: Rebreathing 9. In cases of acidosis‚ the pH of the blood is a. Between 7.4 and 7.55 b. Between 7.35 and 7.45 c. Less than 7.35 d. Greater than 7.55 10. In this lab simulation‚ the minimum pH during rebreathing was _______. 11. If a person is “treated” in a hospital emergency department by breathing in and out of a paper sack‚ this is a classic example of _________ to lower the blood pH. 12. Hypoventilation

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

10 Foreign films for people who don’t watch foreign films Fancy something a little bit different from cliché ridden blockbusters‚ predictable rom coms and endless comic book adaptations? When the current selection at your cinema doesn’t float your boat‚ it might be a good idea to explore foreign film instead. It’s not just for pretentious people‚ you know. I understand that a lot of people seem to be put off by the fact you have to use subtitles and while this can be annoying‚ there is so much

Irresistible? By Elizabeth Potter December 5‚ 2012 Lab Section 503 Abstract The over all goal of the Irresistible lab was to verify a buffer’s ability to resist changes in pH with consecutive 1mL additions of either a strong acid (HCl) or base (NaOH). The experiment entailed preparing a combination 10 buffered and non-buffered solutions and then monitoring the pH changes as a strong acid or base was added to the solution. By performing this experiment‚ it was found that with increasing amounts

PW 3-10: Understand children and young people ’s self directed play Outcome 1 1.1 The characteristics of Self-directed play are freely chosen‚ personally directed‚ intrinsically motivated and goalless. Freely chosen play is where the children choose what they would like to do. Personally directed is where children choose how they want to do it. Intrinsically motivated is where children choose why they do it. Goalless is where they play with no external goal or reward. 1.2 The importance

pH and Chromatography Lab Report Kevin Rivera Biology Mr. Langley 2C 10/7/13 Introduction In this lab‚ of pH and Chromatography‚ in the pH aspect of the lab we are trying to figure out the pH level of certain chemicals by writing down of known solutions to find the type of unkown solution using pH standards. In the Chromatography‚ we are trying to separate the chemicals using water and a piece of paper. Methodology Materials: Safety Goggles pH indicator & pH indicator key
