I personally selected a maroon clownfish with two anemones. I also chose 5 sergeant majors‚ 2 bleenies and a yellow tang. 2. What changes did you make to your reef tank during the 12 weeks and why did you make them? After I selected my fish‚ I noticed that the tank

Lab 6 Biomechanics of Frog Skeletal Muscle I. Purpose This exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

Starch is composed of α-amylose and amylopectin. The structure of α-amylose consists of long polymer chains of glucose units connected by an α (1-4) linkage. Amylopectin consists mainly of α (1-4) linked glucose residues but is a branched molecule with α (1-6) branch points every 24 to 30 glucose residues on average. As a result of the bond angles in the α (1-4) linkage‚ amylose actually forms a spiral much like a coiled spring. Amylose is responsible for the formation of a deep blue color in the presence

My lab group studied the effect of PH on reaction rate/ enzyme activity measured by foam height. PH is the measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration‚ the lower the pH. Every enzyme has an optimal PH‚ meaning they have a very small window in which they are most active. Our enzyme (potato smoothie) had an optimal PH of 7.0-7.5. We know this because we measured the enzyme’s reaction rate by measuring foam height. The largest foam height we

The purpose of my experiment is to determine which temperature will allow Luminol to glow at its greatest capacity. My hypothesis is that the glow will illuminate for the longest time in a cold temperature because it will take longer to dissolve. I also predict that in the warmer temperature‚ the glow will be at it’s brightest. Luminol is a chemical‚ which exhibits chemiluminescence with a blue glow. It is a solid that is soluble in most polar solvents‚ but insoluble in water. Luminol is widely

There are approximately 40‚000 enzymes living in one human cell‚ each responsible for a chemical reaction. Enzymes are complex 3D protein molecules created by amino acids‚ forming a unique sequence that produces hydrogen bonds‚ eventually formulating an enzyme within plants and animals (Boyle & Senior‚ 2002). Working alongside other molecules‚ they uphold a stable reaction system. The function of an enzyme is to aid and increase chemical reactions and organise metabolism‚ while maintaining homeostasis

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded
