The activity of bees and their lives are strongly influenced by the changing seasons. Each month brings about new changes in behavior to a beehive and its occupants. Obviously‚ a beehive is less active during the colder months and more active when the weather is warm‚ but that doesn’t mean you get to ignore the hive completely while they are inactive. That raises the question: is it better to start a beehive in cold weather or warm weather? Understanding how and when bee activity is altered due to

Substrate concentration and yeast catalase Aim: To see how the substrate concentration in hydrogen peroxide affects the rate of an enzyme controlled reaction using yeast catalase. Introduction: An enzyme is a biological catalyst made of protein. Enzymes are protein molecules found in living organisms and in this case I will use a yeast catalase. Catalase is an enzyme that catalyzes the reduction of hydrogen peroxide. Hydrogen peroxide is a poisonous by-product of metabolism‚ so it is very

2 Part 1: In favor of: • Strengths- There is enough conclusive evidence that a reduced salt diet will help decrease future health risks. This shows that over time people that they studied that had a diet that contained less salt showed a decrease risk of developing cardiovascular disease. The fact that they have a few large companies on their side somewhat trying to reduce the amount of salt in their food works well to try and get others to follow. This shows that the companies that will

aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths in 10 seconds

Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product

Mass of water in sample is the mass lost by heating (initial minus final). Water % is 100 times the g of water divided by the initial g of hydrate sample. 4. a. See step A1 in the procedure. b. A hot sample on the balance creates air currents and causes thermal expansion‚ both of which decrease
