membrane more permeable as there are now gaps in the cell membrane allowing bigger molecules such as the betalains to get through. The lipids and proteins in the cell membrane would be destroyed allowing the betalains to leak through the cell. Diffusion Diffusion which is the movement of substances from a higher concentration to a lower concentration through a partially permeable wall will still has to happen as the cell gets its other molecules needed such as carbon dioxide and oxygen through this

The effect of size on the effectiveness of diffusion Aim: To use agar blocks infused with 0.1 Molar sodium hydroxide (NaOH) and phenolphthalein to investigate the relationship between shape and surface area: volume ratio on the effectiveness of diffusion. Hypothesis: That for a cube of agar‚ the time taken for complete colourisation due to diffusion of HCl is directly proportional to the cubes volume. Materials: |A block of agar (10cm x 5cm x 3cm) with 0.1M NaOH and |1x 250mL

Title: Effect of Polarity In Diffusion Of Molecules Across Cellular Membrane Abstract: Cell membranes play an important role in regulating what goes in and out of the cell. Diffusion‚ the process of movement of substances across the cell membrane from higher concentrations to areas of lower concentration‚ plays an active role in the transport and the regulation through cellular membrane. Sometimes‚ there are cases when cells are placed in hypotonic solutions and substances will diffuse through the

The Bystander Effect Why is it so easy to turn away from a problem? To ignore an issue and pretend nothing happened. When we see a crime being committed‚ the easiest option is to sit back and hope that someone else will step in and intervene‚ right? The problem doesn’t concern me; I am not responsible to act. The case of Catherine “Kitty” Genovese in the early 1960s is a painful reminder of the crucial need to intervene. Kitty Genovese‚ a 28-year old daughter of Italian-American parents‚ was

GENERAL DESCRIPTION This innovation‚ originally developed by Microsoft under the codename of Project Natal‚ was finally released under the Kinect name on November 4‚ 2010 and entered the Guinness World Record Book by being the fastest-selling customer electronics device . Even though it was initially designed for video games‚ it now applies to real-world uses. Kinect is a motion-sensing system based around a depth camera that enables the user to control and to interact intuitively‚ and especially

murder. The murder of a young woman with as many as 38 witnesses and none who helped until it was too late. The bystander effect is individuals seeing an emergency situation but not helping. There are many reasons why individuals do not respond: diffusion of responsibility‚ not noticing or unsure if it is an emergency‚ and not wanting to be liable if the person still dies are a few.
