permeable membrane through a process of diffusion. The movement of a solute through this membrane is called dialysis . Diffusion is a form of passive transport. It is the movement of molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors that will affect it’s rate. The rate of diffusion will vary depending on the size of

solutes move via passive diffusion through the plasma membrane. Diffusion is a process where molecules move from an area of high concentration to an area of low concentration. How quickly diffusion occurs is dependent on several factors‚ such as temperature‚ particle size‚ and the concentration difference on either side of the membrane. Testing the hypothesis relating to the effect of molecular weight to the diffusion rate‚ agar plate set-up was used to observe the diffusion of different substances

Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

Kunal Pathade 11/10/13 10-6 WHAP Hebrew Essay: Continuity and Cultural Diffusion The Jews lived to preserve their culture; that essentially represented the fundamental goal of life to the Jews. The Jews observed the decadence of the Sumerians as a cause of cultural diffusion‚ and wanted to make sure that same thing would not happen to them. Eventually‚ the Jews did become vulnerable to cultural diffusion around the 4th century CE when the Greek-Macedonians from the West came; the great and

The effect temperature has on the activity of the enzyme α- amylase. Introduction Enzymes are a biological catalysts‚ which means that they speed up the chemical reactions in living organisms. Almost all of enzymes are energized protein molecules that catalyse and regulate nearly all biochemical reactions that occur within the human body. The reason in which enzymes are sensitive to heat‚ pH and heavy metal ions is because they are made up of proteins. The food we eat is turned into energy by enzymes

Statistics definitions Bias-Bias is a term which refers to how far the average statistic lies from the parameter it is estimating‚ that is‚ the error which arises when estimating a quantity. Errors from chance will cancel each other out in the long run‚ those from bias will not. Primary data-Data observed or collected directly from first-hand experience. Secondary data-Published data and the data collected in the past or other parties Qualitative data-Qualitative methods are ways of collecting

Planaria Regeneration in Ideal Temperatures vs. Cold Temperatures Christina Malfas Abstract Planaria are flatworms that live in quiet freshwater bodies. They live in a narrow range of temperatures‚ from 22-24°C. They regenerate asexually‚ specifically through a process called epimorphosis‚ in which they completely regenerate one half of their bodies after splitting themselves in two. The diffusion gradient model assumes that cells in an organism “know” their orientation on that organism due
