The options for all of them are: Hypertonic Hypotonic Isotonic.
The plasma membrane has a hydrophobic interior due to the two present in each phospholipid found in the phospholipid bilayer of the cell membrane. The plasma membrane allows some molecules to cross but not all. Therefore, the plasma membrane is said to be Molecules that are nonpolar and hydrophobic will cross the membrane with ease by Does this process require energy? When molecules move across the plasma membrane by passive transport, they will move down or with the_ from an area of concentration to an area of. concentration. Polar, hydrophilic molecules and charged ions will move across the plasma membrane by the process of_ This does not require energy, but it does require a A special case of diffusion is known as which is the movement of water across the plasma membrane. If a cell is placed into a solution that is hypertonic compared to the inside of the cell, the cell would If a cell is placed into a hypotonic solution compared to the inside of the cell, the cell water. would…
Why methylene blue, a basic dye, can be used to stain cytoplasm, a basic structure? Why cytoplasm is basic and at the same time negatively charged? I am confused with the terms "basic dye" and "acidic dye". Is it true that a basic dye is positively charged? If so, why is cytoplasm which is negatively charged called basic materials? Could you please explain more on these?
Can you help me with this practice question?
