The Affect of Water Temperature on Goldfish Breathing Rate Carlos Vega Vanessa Santamaria Rasa Hodges 9/12/2013 Introduction The main objective of our lab was to see how temperature affects the breathing patterns of an Ectothermic animal. Ectothermic is the same thing as cold-blooded. It means that the animal‚ in this case a goldfish (Carassius Aauratus)‚ does not produce its own heat internally so the animals temperature depends on the temperature of its surroundings. So

A2 Practical Investigations Title: The effect of Temperature on the growth of Aspergillus oryzae Develop a Hypothesis This particular investigation is to discover how a range of temperatures effects the growth rate of the fungi Aspergillus oryzae. Most fungi’s tend to survive within the temperature range of 5-35oC‚ with the optimum depending on their normal environmental temperature. The fungi Aspergillus oryzae is heterotrophic which means they taken in their food from dead organic matter and cannot

Animal were purchased from the animal house of the faculty of Medicine Mansoura University. The animals were housed in standard stainless steel cages at room temperature 25-28ﾟC‚ humidity of (50-60%) and maintained at 12 hrs alternating day and night cycle. The rats were fed standard pellet diet and water ad libitum. The

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

Lab Report 1: Cell Transport Mechanisms and Permeability Using PhysioEx 8.0 Introduction The purpose of these experiments is to examine the driving force behind the movement of substances across a selective or semiperpeable plasma membrane. Experiment simulations examine substances that move passively through a semipermeable membrane‚ and those that require active transport. Those that move passively through the membrane will do so in these simulations by facilitated

Data Analysis Does temperature affect the strength of Gorilla Glue? If two pieces of wood are glued together at a 90° angle and one is put in the freezer‚one at room temperature‚ and one heated‚ then the glued wood from the freezer will be stronger. The independent variable was the temperature. The dependent variable was the strength of the glue. Some constant variables were the amount of glue‚ the type of glue‚ and the type of wood used. The experimental group was the temperatures. The control group

which pertains to how much energy is needed for chemical reactions to take place. Enzymes also known as catalysts is one of the main factors in producing energy in individual’s bodies. The experiment conducted was to test how different temperatures effected the catabolizing of fungal and bacterial amylase‚ as well as the optimal temperature needed for the enzyme to correlate with the bacteria and fungi. The enzyme’s break down within the starch was observed through different temperatures and time periods

PART B YOU WILL NOW DESIGN AN EXPERIMENT TO STUDY THE EFFECT OF A FACTOR AFFECTING VITAMIN C IN FRUIT JUICES WHAT IS THE EFFECT OF TEMPERATURE ON VITAMIN C IN FRUIT JUICES? The purpose of this experiment is to determine if the difference in temperature will damage vitamin C in any type of fruit juices. Five different temperatures of fruit juices will be used(5‚ 22‚ 50‚ 70‚ 90) degree Celsius to see how temperature affects the loss of vitamin C in fruit juices. The amount of vitamin C in the fruit
