Question

match each condition to its effect on diffusion rate by dragging each label into the appropriate box. labels drop zones reset all vill and microvilli in the intestinal epithelium increases rate of diffusion (1/2) decreases rate of diffusion (2/2) decreased cell height, creating a flatter cell approaching diffusional equilibrium decreased molecular weight increased temperature

Explanation:

• Villi and microvilli in the intestinal epithelium increase surface - area, thus increasing diffusion rate.
• Decreased cell height (flatter cell) shortens diffusion distance, increasing diffusion rate.
• Approaching diffusional equilibrium reduces the concentration gradient, decreasing diffusion rate.
• Decreased molecular weight allows for faster movement, increasing diffusion rate.
• Increased temperature increases molecular kinetic energy, increasing diffusion rate.

Answer:

Increases Rate of Diffusion (1/2): Villi and microvilli in the intestinal epithelium, Decreased cell height, creating a flatter cell, Decreased molecular weight, Increased temperature
Decreases Rate of Diffusion (2/2): Approaching diffusional equilibrium
