19 BIO.A Compare the mechanisms that transport materials across the plasma membrane (i.e., passive transport diffusion, osmosis, facilitated diffusion; and active transport pumps, endocytosis, exocytosis). Correct Answer: Web s: DOK Level 2 Analyzing/Analysis Solution Sample Answer What happens to the slug Dies and shrinks Why - This is due to osmosis. The skin of the slug acts as a semi-permeable membrane where there are different concentrations of salt and water on each side. Remember that water will move from an area where there is more water to an area where there is less water. The salt that you sprinkle on the slug mixes with water in the slime on the outside of the slug to make a salty solution. In any solution there is only so much room, so if there is a lot of salt, there is not a lot of water. There is more water, less salt on the inside of the slug, so water leaves the slug to mix with the salt outside the slug in order to equalize (or "more equalize") the water on both sides of the membrane. There is a net loss of water from the slug and it dehydrates to death.

20 35. Your teacher will provide you with instructions on where to answer this question. The cycle diagram represents the relationship between photosynthesis and cellular respiration. What materials do box 1 and box 2 represent? Explain the cycle diagram using the two types of energy transformation including the efficiency of the cycle. Make sure you explain using the biological process and biological terminology. BIO.A Compare the basic transformation of energy during photosynthesis and cellular respiration. Correct Answer: Web s: DOK Level 2 Analyzing/Analysis Solution Sample Answer What materials do box 1 and box 2 represent? Box 1 - Oxygen, Box 2 - Carbon Dioxide Explain the cycle diagram - Photosynthesis is the energy process used by plants and it produces oxygen, which is then used by animals as an element in cellular respiration. The product of cellular respiration is carbon dioxide, which is used by plants in photosynthesis. And the cycle continues indefinitely and is very efficient each process producing what the other process needs.
