of Fermentation (How Yeast Get Energy) Purpose: To study how the rate of fermentation by yeast cells is affected by the concentration of molasses. You will be using yeast cells (microscopic organisms) and molasses (a product of photosynthesis in sugar cane). You will measure the rate of fermentation by measuring how much carbon dioxide (CO2) is given off by the yeast cells over a certain period of time. Materials Goggles 6 test tubes (18mm x 150 mm, for example), rimless

Transpiration and Leaf Resistance By: Bernina Berber Due: February 24, 2011 Lab: Thursday 1:40pm Section: 15227 Introduction Transpiration is a part of the water cycle process, and it is the loss of water vapor from parts of the plants. It is a process similar to evaporation. Evaporation and diffusion cause the plant tissue to have negative water potential. If you were to compare transpiration it would be like saying it is close to sweating (but in plants), especially in leaves but also

Characterization of Halophiles Student Name: Brittany Barnes Student Number: 5408224 Lab Section: 35 Date Experiment Performed: January 13, 2014 Lab Partners: Kayla Hutchinson Fallon Fersaud Ashley Maulucci Abstract Halobacterium salinarum and Haloferax volcanii come from the domain called Archaea and are considered to be halophilic, because they thrive in extreme environments. In this lab experiment, several tasks took place. In order to be able to observe the colony morphology

Yeast Culture Lab I. Introduction 1. Yeasts are eukaryotic, unicellular fungi that inhabit liquid or moist habitats. They are heterotrophs and rely on complex organic substances for nutrition. Yeasts require oxygen for aerobic cellular respiration but some are also anaerobic with alternative aerobic methods for producing energy. They do not require light to grow and their temperature range varies which means they can survive in a multitude of different environments. Very common, they can be found

THERMOCHEMISTRY OF NaOH AND HCl LAB Overview Teacher’s Instruction: Find the Molar Heat of Reaction for the NaOH reaction. Then, predict and calculate the change in enthalpy (ΔE) and change in heat (ΔH) when 5.00g NaOH reacts completely with HCl. Reaction Equation: NaOH(s) + HCl(aq) -> NaCl(aq) + H2O(liq) Net Ionic Equation: Na(OH)(s) + H+(aq) -> H2O(liq) + Na+(aq) The Big Question: If we combine solid NaOH and aqueous HCl, how will the temperature change? What will the change be with
