are exposed daily to oxygen (such as fruits‚ vegetables and animals). Background Information The Catalase enzyme in this experiment is known for being less affective the warmer the temperature is. According to “Science fair projects” an enzyme becomes unstable at higher temperatures and the shape of the enzyme changes. The enzyme is also used to remove hydrogen peroxide from clothing in the textile industry. This would make sense because when an enzyme encounters a substrate molecule

Problem Question: * What effect does temperature have on the rate of Diffusion? Hypothesis: If we put the antacid in hot water‚ then it will dissolve faster than in cold water or room temperature water. Material List: * One thermometer * 3 beakers (of the same size) * 3 antacid tablets * Cup of ice * Hot plate * Paper towels * Water Procedures: Step 1: Gather materials Step 2: Label the beaker #1‚ #2‚ and #3 Step 3: Fill each beaker with the same amount of

The Effect of Varying Temperatures to the Rate of Respiration of Bufo marinus Statement of the problem: At which environmental temperature‚ do toads have the highest respiration rate? Most animals obtain oxygen‚ which comprise 21% of the air‚ from the environment. Oxygen combines with hemoglobin of the blood to form oxyhemoglobin. Oxyhemoglobin is transported to the tissues where oxygen is released and used for the metabolic functions of the animal. The functions produce waste materials‚ such

Hypothesis: I believe that the racket ball will have a faster average speed than the tennis ball for both distances because the racket ball is bouncy. Materials: *Tennis ball *30yards of space *Racket ball *Set of stairs *Stop watch *measuring tape Procedures: 1) Measure out 30 yards of space‚ have of member stand

The Speed Reading Course By Peter Shepherd & Gregory Unsworth-Mitchell Email: shepherd@trans4mind.com Web site: Tools for Transformation Copyright © 1997 Peter Shepherd The Basics of Reading Introduction We all learn to read at school‚ after a fashion. But for most of us‚ this is not an optimal use of our brain power. In this course you will learn to better use the left brain’s focused attention combined with the right brain’s peripheral attention‚ in close harmony. Good communication

The effects of environmental temperature on respiration rates of mice were observed in this experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable

seemingly intricate things in nature can be understood in terms of relatively straightforward mathematical relationships. These mathematical relationships are a recurring concept in the fields of Kinematics and Dynamics which focuses on ways in which objects/matter move whilst evaluating behaviours like displacement‚ acceleration and velocity (Wise Geek‚ 03-13). Kinematics derives its name from the Greek word for “motion” (kinema) (Sparknotes‚ 2011). This field is centred under a sub branch of mechanics

Introduction Cell respiration is the process of a cell converting sugars into ATP (energy) in the mitochondrion. It is an essential process which enables organisms to survive and function (Biology Online‚ 2010). Not only does it produce ATP‚ but also carbon dioxide (though decarboxylation)‚ NADH and FADH and in the case of some organisms‚ alcohol. Saccharomyces cerevisia‚ a bacterium commonly known as yeast‚ is used in various aspects of life‚ from winemaking to baking. It respires both anaerobically

recognition of the 3D blocks. It seems that in the rotation of these images familiarity plays a very important role‚ since it can be assumed that if familiarity is true‚ then subjects who are familiar with any object or behavior will find it easier to make a mental rotation. 2. The results showed the typical effect of mental rotation on response times. There were moments when I could not tell if the shapes were different or the same. As when a rotated object is presented to us‚ we mentally tend to turn
