Question

1. movement away from high solvent concentration or towards high solute concentration describes (click to select). 4. water diffusion thr membrane is made easier by membra (click to select) concentration gradient filtration high hydrophilic hydrophobic low osmosis osmotic pressure

Explanation:

Question 3

To solve this, we analyze each option:

• "concentration gradient": Describes the difference in solute/solvent concentrations, not the movement. Eliminate.
• "filtration": Involves pressure-driven movement, not solute/solvent concentration - based. Eliminate.
• "high"/"low": Are just concentration levels, not the movement process. Eliminate.
• "hydrophilic"/"hydrophobic": Relate to water - attraction/repulsion, not the described movement. Eliminate.
• "osmosis": Is the diffusion of water (solvent) from high solvent (low solute) to low solvent (high solute) concentration, which matches the description.
• "osmotic pressure": Is the pressure related to osmosis, not the movement itself. Eliminate.

• "concentration gradient": Drives osmosis but doesn't "make diffusion easier" in terms of membrane structure. Eliminate.
• "filtration": Not related to facilitating water diffusion through membrane structure. Eliminate.
• "high"/"low": Concentration levels, not facilitators. Eliminate.
• "hydrophilic": Membrane parts (like aquaporins) that are hydrophilic allow water to pass easily, as water is polar and hydrophilic regions interact favorably with it. This fits.
• "hydrophobic": Repels water, so would not make water diffusion easier. Eliminate.
• "osmosis": The process, not a facilitator. Eliminate.
• "osmotic pressure": Related to osmosis, not a facilitator. Eliminate.

Answer:

osmosis

Question 4 (Assuming the full question is about what makes water diffusion through a membrane easier, likely referring to aquaporins which are hydrophilic channels, but from the options, "hydrophilic" is the key as membrane components that are hydrophilic (like aquaporin channels) facilitate water diffusion. Let's confirm:
