Answer the following question given this paragraph: Refraction is another way that waves interact with matter. Refraction occurs when waves bend as they enter a new medium at an angle. You can see an example of refraction in Figure below . Light bends when it passes from air to water. The bending of the light causes the pencil to appear broken. Q: Light bends when it passes in from what to what? Choices: - air to ground - product to water - water to air - air to water A:
**Answer**
air to water

Answer the following question given this paragraph: Starches are complex carbohydrates that are polymers of glucose. Starches are used by plants to store energy. Consumers get starches by eating plants. They break down the starches to sugar for energy. Q: What complex carbohydrates are the polymers of glucose? Choices: - sugars - fats - fruits - starches A:
**Answer**
starches

Answer the following question given this paragraph: Primary Producers/Food Sources Protists are essential sources of nutrition for many other organisms. In some cases, as in plankton, protists are consumed directly. Alternatively, photosynthetic protists serve as producers of nutrition for other organisms. For instance, photosynthetic dinoflagellates called zooxanthellae use sunlight to fix inorganic carbon. In this symbiotic relationship, these protists provide nutrients for coral polyps (Figure 23.29) that house them, giving corals a boost of energy to secrete a calcium carbonate skeleton. In turn, the corals provide the protist with a protected environment and the compounds needed for photosynthesis. This type of symbiotic relationship is important in nutrient-poor environments. Without dinoflagellate symbionts, corals lose algal pigments in a process called coral bleaching, and they eventually die. This explains why reefbuilding corals do not reside in waters deeper than 20 meters: insufficient light reaches those depths for dinoflagellates to photosynthesize. Q: Without dinoflagellate symbionts, corals lose algal pigments in a process called coral bleaching and eventually die, while corals in turn provide protection, making this what type of relationship?. Choices: - idealistic - semantic - parasitic - symbiotic A:
**Answer**
symbiotic
