Were you able to use the same weight on the stability ball? If not‚ why do you think you could not use as much resistance? What populations would benefit from stability ball training? Are there certain individuals who should not use a stability ball? How will this learning experience and the knowledge you have gained from it help you in your future training endeavors?

chrysalises each student put 1 of their containers into a cold climate approximately 45°F‚ 1 in a warm climate approximately 85°F and 1 stayed out at room temperature approximately 72°F. The larvae spent a total of 5 days in each climate‚ and then they were removed and brought back to room temperature. Then the waiting game started to see how long it took each larva to go through metamorphosis and emerge as a butterfly. Based on the data that was recorded it looks like the larvae turned into butterflies

Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can be used to find out how temperature

reaction can be explosive. 2KMnO4 + 2 H2SO4 → 2 KHSO4 + Mn2O7 + H2O These activities show that different substances catch fire at a different temperature. The lowest temperature at which a substance catch fire is called its ignition temperature. Combustible substances do not catch fire or burn as long as its temperature is lower than its ignition temperature. Now let me do an activity which tells you why reaching ignition temperature is necessary to burn an object. You know that paper catch fire with

The Activity of a Protease (Trypsin) Introduction Enzymes catalyze reactions by creating alternate reaction mechanisms whose transition states are more thermodynamically stable than uncatalyzed reactions (Berg et al.‚ 2002; UBC Department of Microbiology and Immunology‚ 2006). Increased thermodynamic stability in these transition states reduces the energy of activation‚ the minimum amount of energy input a chemical system requires for a reaction to occur (UBC Department of Microbiology

If it is looked as one continuous line‚ the first part of the trend line shows a steep‚ straight and constant decrease; then the 2nd part is not as steep and has a more gradual decline. Moreover‚ it shows how a reaction at 20°C a slower time for the cross to disappear compared to 40°C and especially 60°C. Both graphs show how temperature has a great effect on the speed of sulfur

the assignment to pick an experiment‚ change the independent variable‚ come up with a hypothesis‚ test our experiment with the new independent variable‚ and confirm or reject our hypothesis. We picked experiment 2. In this experiment‚ water was combined with baking soda. Then the temperature was taken‚ and finally calcium chloride was added‚ which formed a chemical reaction. Our lab question was how does the amount of calcium chloride affect the temperature of the product? We chose our independant

highest rate of reaction is at pH 7. This therefore supports my theory that at pH 7 the rate of reaction will be highest. This relate to other resources‚ such as books and the internet‚ which show that the optimum pH value for catalase is pH7‚ therefore there is no difference between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active. However the graph inadequately supports the second part of the prediction‚ that the rate will

because of the ocean temperatures rising? One reason the ocean temperature surges is because of the greenhouse gas. As greenhouse gas (a gas from the greenhouse effect that benefits by absorbing carbon dioxide‚ chlorofluorocarbons‚ and infrared radiation; different kinds of elements and gases) collects together and increases‚ it traps more heat energy into the Earth‚ and making the temperature rise. Another way this is caused is when the warmer ocean water makes movement‚ it changes the climate condition
