As the temperature increases, the rate movement heat has the ability to accelerate the rate of diffusion due the increasing the speed of molecules thus enabling a quicker pace of reaction. Thus, an increase in the temperature of a substance implies that the average kinetic energy of the particles of the substance has increased. As the kinetic energy of the particles increases, the particles begin to move faster. The experiment aimed to determine whether temperature can influence the rate of a reaction. The investigation clearly showed that temperature is the pinnacle for a faster reaction, highlighting as the temperature increased, the speed of reaction increased, therefore diffusion occurred at a faster rate.SAMPLE TIME TAKEN COMPLETE DIFFUSION (s)Hot water90Cold water 646Figure 1.1

The demonstration of OsmosisMATERIALS AND METHODAs described in the Human Physiology 1 Practical Manual VU, 2019No changes were applied according to the materials and methods given.RESULTSIn this experiment, it illustrates the demonstration of osmosis and how different solutes effect the net movement of water. The overall result is aimed to utilise whether they are existing substances of either glucose, protein, or sodium chloride is prevalent to net movement. Glucose is not able to go through a plasma membrane and therefore needs assistance by facilitated diffusion.Protein has the ability to go through the selectively permeable membrane passively due to the size it is. Sodium chloride is an ion, therefore it is minuscule in size, creating the ability to go through the semi permeable membrane passively.
As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
