us and the environment. We used Nutrient Agar which is a growth medium used to culture microorganisms or small plants and Sabourand Dextrose Agar plates used to cultivate moulds and yeasts. The objective of it was to demonstrate that microbes are everywhere. We expected to find a variety of bacteria‚ moulds and yeasts. We were introduced to aseptic techniques as they help ensure that only certain microorganisms are present in the plate. These methods also guarantee that microorganisms do not escape

3A Task 1 Aim: the aim of the experiment is to find the best temperature to ferment yeast at. Hypothesis: the yeast will ferment the best at 60 degrees Celsius. Independent variable: the temperature of the water the yeast is put in to ferment. Dependent variable. The amount of air bubbles the yeast produces. Controlled variable: the amount of yeast and glucose in each syringe. Uncontrolled variables: human error in counting. Materials : Plastic soft drink bottle cut to size Marking pen

RaeAnne Smith HL Biology Y2 Soule: Period 7 10 October 2011 Affect of Sugars on Yeast Respiration Introduction Cellular respiration can be defined as the release of energy‚ or the breakdown of carbohydrates into carbon dioxide and water1. Cell respiration takes place in the mitochondria of animals and in the cytoplasm of plants. The formula for aerobic cellular respiration is: c6H12O6+ 6O2→6CO2+6H2O Aerobic respiration occurs when oxygen is present‚ while anaerobic respiration occurs when

Nebojsa Kuljic 10066717 Partner: Kendra Skalyn B02 Introduction Cells of all organisms can obtain energy through the combustion of sugars‚ either in the presence of oxygen (Aerobically) or without oxygen (Anaerobically). The purpose of this experiment was to perform a quantitative investigation of the differences between Anaerobic and Aerobic metabolism using pea seedlings and yeast organisms [1]. Aerobically‚ sugars such as glucose are transformed into pyruvate [2] and

face the challenges of having an “abnormal baby”‚ others are willing to accept their child as he/she is. In this story‚ The Monster on Her Cheek‚ Rebecca Roland demonstrates the emotional struggle but choosing to embrace her child either way. In the setting‚ Roland started off her narrative with a baby who was just born with a strange “monster” on her cheek. The nurse couldn’t look at Wendy‚ the mother‚ in the eyes and even apologized. This shows how even the nurse felt awful for the mother‚ leaving

Would you change your culture to please other people? In the descriptive short story‚ Fish Cheeks‚ describes a family meal where two different groups of people shared their culture. Amy Tan explained the story in great detailed and also taught an excellent lesson about not being afraid to be diverse from other people. “You must be proud you are different. Your only shame is to have shame.” People act different‚ culture wise yet‚ at the end of the day everyone is alike. Sharing your heritage

Cellular Respiration in Yeast Lab Report Form Your Name: “What do you think? – What do you know?” Questions: In this lab‚ we will investigate the effect of sucrose concentration on the rate of cellular respiration in yeast. Under specific conditions‚ yeast will convert sucrose into glucose and then use this glucose in cellular respiration. 1. Yeasts have been used by humans in the development of civilization for millennia. What is yeast? How have humans used yeasts? They are most common

Misconception #1: All locksmiths use the same products. No. Just like everything else in the world - there are good products and there are bad products. There are excellent‚ precision locks and there are low-grade locks. You get what you pay for. If you pay for quality locks you will get quality performance. If you cut corners and use cheap locks‚ they will probably not last very long and will perform poorly if attacked. Misconception #2: All locksmiths give you the same service. No. There are

temperature on the rate of fermentation in yeast by measuring the height of CO2 produced in a graduated cylinder at varying degrees Celsius. Yeast can perform cellular respiration and fermentation‚ the first needing oxygen (aerobic) and the second not (anaerobic). Cellular respiration is the normal way human bodies’ make energy‚ but when lacking oxygen‚ cells undergo fermentation‚ which creates less energy than respiration‚ CO2‚ and lactic acid (though in yeast‚ ethel alcohol is made instead of lactic

In the story Fish Cheeks by Amy Tan is about a event in Amy’s. Amy is a young Chinese girl that has a crush on the minister’s son. At one point in Amy’s life her mother invites the minister’s family over for a Christmas eve dinner. After being told she was very apprehensive of the minister’s son and his family coming over for dinner. The reason she was so apprehensive was because of the meal that her mother cooked wasn’t a traditional American dinner. But it was all traditional Chinese food. Amy
