Design IA Research Question How Does Increasing the Intensity of Exercise Affect Respiratory Rate? Hypothesis My experiment will involve sprinting which is a very demanding and fatiguing sport. In order to increase the intensity of it‚ I will be increasing the weight the subject has to carry as he sprints. My hypothesis is that as you increase the weight‚ the respiratory rate will also increase. At rest‚ the average breathing rate for adults is 12-24 breaths per minute and for new born babies

summarized by the equation: . Enzymes play a very significant part in respiration. During the different stages of respiration‚ enzymes that are often found in the matrix of the mitochondria are used to speed up reactions in the body by reducing a reaction’s activation energy‚ which means that less energy is required to start a reaction. Enzymes need to collide with their respective substrates in order to generate a reaction‚ increasing the temperature will give the enzymes and their substrates more energy

Matthew Saldanha Bio DCP lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it

two Title: Enzyme Function Purpose: To observe the role of enzymes in chemical reactions and to determine the kinds of cells that contain more of the enzyme catalase. Prior Knowledge: Enzymes are proteins that assist the chemical reactions of a cell by lowering the amount of activation energy needed to start the reactions‚ thereby enabling the cell to carry out the reactions at a faster rate; enzymes that lower the activation energy are therefore called catalysts. Moreover‚ the enzyme itself is

bung. 7. Take measurement of gas after 2 minutes. 8. Repeat. Investigating the effect of enzyme concentration on the rate of an enzyme-catalysed reaction. James Moore Conclusion: For the conclusion we see that in fact the hypothesis is correct. When independent variable increases so does the dependent variable. As the amount of enzyme concentration increases so will the rate of the enzyme catalysed reaction. In the human body substrate is always available therefore there is only one

IB Economics: Practice Internal Assessment The article “Chinese Dragon bites Local manufacture as Importers laughs last” stated that the imported products‚ majorly from China have became a threat to the local economy in Uganda. The Ugandan government have taken measure ease production on local traders by scrapping the pre-inspection fees and planning to construct industrial parks to lower the hiking cost of production of local products. Chinese products are cheaper and more competitive comparing

Introduction In the Caribbean and specifically in Jamaica‚ the most accepted language for communication is that language left to us by our European colonisers. The pidgin that developed from the contact of the African slaves and European masters later developed into their own individual languages (or Creoles). They (the elite in society) shun these languages as inappropriate or inadequate for public and sometimes even private use. This notion is widely accepted by even those who can speak nothing

General Introduction Teenage Pregnancy The topic I’ve selected is teenage pregnancy. The issue of teenage pregnancy has been a dominant factor affecting the lives of the members of my community Old Harbour Bay. The term teenage pregnancy can be best defined by “pregnancy in a young woman who has not reached her 20th birthday when the pregnancy ends regardless of whether the woman is married or is legally an adult age (14-21). Why I’ve decided to undertake the task of doing this topic is that

Commentary on: Pecan market is a-crackin’ In the last few years the economic growth of China has caused the demand (and supply) of all kinds of nuts‚ especially pecans‚ to rise and producers are facing a challenge meeting the soaring demand‚ says “The Globe and Mail” October 18th 2010. Demand and supply are the quantity of a good or service that consumers and producers are willing able to purchase and produce at a given price in a given time period. Equilibrium is a state of rest‚ self-perpetuating
