Answer

  1. Diffusion:
    1. Provide a diagram showing molecules moving from high to low concentration.
    2. Molecules move from an area of high concentration to low concentration.
    3. No energy is needed for diffusion.
    4. It is passive because it does not require energy input.
    5. Small, nonpolar molecules like oxygen and carbon dioxide use diffusion.
  2. Facilitated Diffusion:
    1. Provide a diagram showing molecules moving through a protein channel.
    2. Molecules move from an area of high concentration to low concentration.
    3. No energy is needed for facilitated diffusion.
    4. It is passive because it does not require energy input.
    5. Larger or polar molecules like glucose and ions use facilitated diffusion.
    6. Facilitated diffusion uses protein channels, unlike regular diffusion.
  3. Osmosis:
    1. Provide a diagram showing water moving across a semipermeable membrane.
    2. Water moves from an area of low solute concentration to high solute concentration.
    3. No energy is needed for osmosis.
    4. It is passive because it does not require energy input.
  4. Active Transport:
    1. Provide a diagram showing molecules moving against the concentration gradient.
    2. Molecules move from an area of low concentration to high concentration.
    3. Energy is needed for active transport.
    4. It is active because it requires energy input, usually in the form of ATP.
  5. Homeostasis Application:
    1. Homeostasis is the maintenance of a stable internal environment in an organism.
    2. Examples include: regulation of blood glucose levels through insulin and glucagon, and maintaining ion balance through the sodium-potassium pump.
  6. Final Grade:
    1. Calculate the total score out of 100.
    2. Add +0 for 2D or +10 for 3D projects.
    3. Provide the final grade.
