The Changes of Heart Rate of Students during Human Dive Response when Resting and Submerged Abstract The dive response is known more popularly as a mammalian dive reflex. It is a survival mechanism built into mammal’s bodies‚ essentially. Over the years‚ scientists have been determined to find what triggers mammals to have a decreased heart rate when submerged under water allowing them to stay under the water longer when they do not typically live under water. In this experiment‚ we tested

The data found in this experiment supported the initial statement in the hypothesis‚ that blue would have the highest rate of photosynthesis (see Figure 7). The second part of the prediction was refuted by the data‚ as green had a higher rate than both yellow and red. This result seems to go against the experiment‚ however the answer is in Figure 5. When adding green food coloring to the solution (see Methods) dilution also took place. When comparing the wavelength of 540 nm (see Tables 1 & 2) with

Throughout the course of my high school education‚ I was treated as "one of the exceptions"‚ meaning that to my white peers‚ and even black peers

Enzyme Activity How does temperature affect enzyme activity? In this practical investigation‚ my aim is to discover how temperature will affect enzyme activity‚ by looking at the rate of reaction. I predict that the higher the temperature will be‚ the faster the reactions take place. However‚ I also think that there will be an optimum temperature‚ at which the reaction will work at its fastest; if the temperature goes beyond that‚ the reactions will stop altogether as the enzymes would have
