Answer the following question given this paragraph: Ants and termites grow fungi in underground "fungus gardens" that they create. When the ants or termites have eaten a big meal of wood or leaves, they also eat some fungi from their gardens. The fungi help them digest the wood or leaves. The fungi secrete certain enzymes that the ants or termites cannot produce on their own. Q: What do ants and termites eat to help them digest wood and leaves? Choices: - pollen - berries - yeast - fungi A:
fungi
Answer the following question given this paragraph: A lipid is an organic compound such as fat or oil. Organisms use lipids to store energy, but lipids have other important roles as well. Lipids consist of repeating units called fatty acids. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids. Q: What are the two types of fatty acids? Choices: - saturated and biodegradable - saturated and endogenous - hydrochloric and carboxylic - saturated and unsaturated A:
saturated and unsaturated
Q: Answer the following question given this paragraph: This plot of temperature shows what happens to a 75 g sample of ice initially at 1 atm and 23C as heat is added at a constant rate: AB: heating solid ice; BC: melting ice; CD: heating liquid water; D E: vaporizing water; EF: heating steam. Thus the temperature of a system does not change during a phase change. In this example, as long as even a tiny amount of ice is present, the temperature of the system remains at 0C during the melting process, and as long as even a small amount of liquid water is present, the temperature of the system remains at 100C during the boiling process. The rate at which heat is added does not affect the temperature of the ice/water or water/steam mixture because the added heat is being used exclusively to overcome the attractive forces that hold the more condensed phase together. Many cooks think that food will cook faster if the heat is turned up higher so that the water boils more rapidly. Instead, the pot of water will boil to dryness sooner, but the temperature of the water does not depend on how vigorously it boils. Q: What happens to the temperature of a system during phase change? Choices: - increases - fluctuates rapidly - decreases - remains constant A:
A: remains constant
Question: Answer the following question given this paragraph: Cnidarians have an incomplete digestive system with a single opening. The opening is surrounded by tentacles, which are covered with nematocyst cells and used to capture prey. Digestion takes place in the digestive cavity. Nutrients are absorbed and gases are exchanged through the cells lining this cavity. Fluid in the cavity supports and stiffens the cnidarian body. Q: What organism is characterized by an incomplete digestive system and a single, tentacled opening? Choices: - annelids - prokaryotes - sponges - cnidarians A:
Answer: cnidarians
