membrane transport

Explanation:

Since the problem is about membrane transport in cells, which is a topic in Biology (a subfield of Natural Science), and assuming we need to match the letters (though the terms to match aren't provided, we can explain the typical components):

• A: Likely represents passive transport (diffusion, facilitated diffusion) as molecules move down concentration gradients (purple, red, blue molecules move from high to low).
• B: Likely active transport (requires energy, shown by the yellow energy symbol) as orange/diamond molecules move against concentration gradients.
• C: Simple diffusion (purple molecules move through the lipid bilayer without a protein).
• D: Facilitated diffusion (red triangles move through a channel protein, E, down gradient).
• E: Channel protein (allows specific molecules through).
• F: Carrier protein (facilitates blue molecules' movement down gradient in A, or in B, maybe for active transport).
• G: Energy source (like ATP) for active transport in B.
• H: Plasma membrane (phospholipid bilayer).

To match, we analyze each letter:

• A: Passive Transport (includes simple/facilitated diffusion, no energy)
• B: Active Transport (needs energy, moves against gradient)
• C: Simple Diffusion (molecule moves through lipid bilayer)
• D: Facilitated Diffusion (molecule moves through channel/carrier down gradient)
• E: Channel Protein (integral membrane protein forming a pore)
• F: Carrier Protein (binds and transports molecule, can be passive/active)
• G: Energy (e.g., ATP) for active transport
• H: Plasma Membrane (phospholipid bilayer structure)

Answer:

• A: Passive Transport
• B: Active Transport
• C: Simple Diffusion
• D: Facilitated Diffusion
• E: Channel Protein
• F: Carrier Protein
• G: Energy (e.g., ATP)
• H: Plasma Membrane

(Note: If specific terms were provided, we'd match each letter to the correct term. The above is based on typical membrane transport figure components.)
