4. conclusion

For this question, you need to come up with a problem and then use the steps to solve it. I will give you an example here but you can use any problem you like. I am just using the example below to illustrate the steps of the scientific method.

Example:

Problem: Do tomato plants grow taller with fertilizer?
Observation: Fertilizer is used by many farmers to grow bigger plants, Does fertilizer really help tomato plants grow taller?
Hypothesis: The fertilized tomato plants will grow taller than the unfertilized plants.
Experiment: Set up three unfertilized tomato plants and three fertilized plants. They must be the same size and they have to be kept under the same conditions. The only difference must be that there is fertilizer added to three of the plants. The other three plants serve as a control. ...

  • Discussion of Diffusion, Osmosis and Cell Membrane Potential

    This solution provides real world examples to help illustrate the scientific principles of diffusion and osmosis. Additionally, the cell membrane and membrane potential are also discussed. Useful links are included.

  • How do substances (ions, proteins, ligands etc. etc.) cross

    Separating the intra- and extracellular space is also a core component in the definitions of life. Diffusion - This method of moving substances utilizes potential energy stored in a gradient.

  • Part of the lab final





    Osmosis:

    Osmosis is a specialized form of diffusion, it is a type of diffusion. It deals specifically with the movement of water molecules across a concentration gradient.

  • Active/Passive Transport and role of ATP

    No external source of energy is required. What is the difference between diffusion and osmosis? Diffusion - movement of solutes Osmosis - diffusion of water.

  • Diffusion, osmosis, and facilitated diffusion

    The diffusion of a substance across a membrane is called passive transport. Diffusion is the spontaneous movement of a substance down its concentration gradient. Osmosis is the diffusion of water across a selectively permeable membrane.

  • Comparing Osmosis and Diffusion

    Diffusion is the movement of substances from an area of high concentration to an area of lower concentration. Osmosis is basically the diffusion of water.

  • Different Factors Influencing the Diffusion Rate

    Since diffusion is driven mainly by these collisions between solutes and solvents, the rate of diffusion would increase. Osmosis experiment 1.

  • Osmosis & Diffusion

    The solution discusses questions about osmosis and diffusion of sugar molecules.

  • Desert animals

    The proximal tubes of the kidneys re-absorb water by an intricate process of diffusion termed osmosis (definition of osmosis = transfer of a liquid solvent (H2O) through a semi-permeable membrane that does not allow dissolved solids (solutes) to pass.
