WebA selectively permeable (or semi-permeable) membrane is a thin layer of material that contains holes of various sizes, or pores. Selective permeability means that small substances and fluid, such as small sugar, salt and water, can move freely in either direction across the membrane but the movement of larger substances are prevented … WebSome molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic core. In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from … Here, the cell can't import glucose for free using diffusion, because the natural … WebLugol’s iodine causes cornstarch to turn a blue - black color. Starting with three test tubes containing 10 mL of the three Lugol’s iodine solutions (A, B, or C). We will run 3 trials in which we vary the concentration of iodine in our setup. We will observe how the rate of diffusion of iodine across the plastic membrane varies with iodine ... blichmann boil coil
