Answer the following question given this paragraph: Describe why algae is a good source of biofuel. Q: What type of organism is algae? Choices: - virus - amoeba - yeast - bacteria (cyanobacteria) A:
bacteria (cyanobacteria)
Answer the following question given this paragraph: Lysosomes Some of the protein products packaged by the Golgi include digestive enzymes that are meant to remain inside the cell for use in breaking down certain materials. The enzyme-containing vesicles released by the Golgi may form new lysosomes, or fuse with existing, lysosomes. A lysosome is an organelle that contains enzymes that break down and digest unneeded cellular components, such as a damaged organelle. (A lysosome is similar to a wrecking crew that takes down old and unsound buildings in a neighborhood. ) Autophagy ("self-eating") is the process of a cell digesting its own structures. Lysosomes are also important for breaking down foreign material. For example, when certain immune defense cells (white blood cells) phagocytize bacteria, the bacterial cell is transported into a lysosome and digested by the enzymes inside. As one might imagine, such phagocytic defense cells contain large numbers of lysosomes. Under certain circumstances, lysosomes perform a more grand and dire function. In the case of damaged or unhealthy cells, lysosomes can be triggered to open up and release their digestive enzymes into the cytoplasm of the cell, killing the cell. This "self-destruct" mechanism is called autolysis, and makes the process of cell death controlled (a mechanism called "apoptosis"). Q: What structure is an organelle that contains enzymes that break down and digest unneeded cellular components? Choices: - peroxisome - tissue - centrosome - lysosome A:
lysosome
Q: Answer the following question given this paragraph: The part of each nephron called the glomerulus is where blood in the capillaries is filtered. Excess water and wastes are filtered out of the blood. The tubule of the nephron collects these substances. Some of the water is reabsorbed. The remaining fluid is urine. Q: Which part of the nephron collects wastes in the blood? Choices: - filter - vesicle - waste sac - tubule A:
A: tubule
Question: Answer the following question given this paragraph: In many species, display behaviorsrather than actual physical attacksare used to show aggression. This helps prevent injury and death. Male gorillas, for example, are more likely to put on a display of aggression than to attack another male. In fact, gorillas have a whole series of display behaviors that they use to show aggression. They beat on their chest, dash back and forth, and pound the ground with their hands. Q: In many species, display behaviors, like a gorilla beating on its chest, are used instead of actual physical attacks to show what? Choices: - dominance - friction - stress - aggression A:
Answer: aggression

Answer the following question given this paragraph: Roots grow in length and width from primary and secondary meristem. Q: Roots grow in length and width from the primary and secondary what? Choices: - pistil - frill - leaf - meristem A:
**Answer**
meristem
Q: Answer the following question given this paragraph: Viscosity measures a fluid's resistance to flow the higher the viscosity, the slower the flow of the material. One factor that affects viscosity is the strength of the intermolecular forces in the material. Molecules that exhibit higher intermolecular forces tend to have higher viscosities. Temperature also influences viscosity. A higher temperature results in a decrease in viscosity, since molecules are moving faster and the intermolecular forces are more easily disrupted. Most cooking oils are more viscous than water, but when heated, the viscosity decreases and the oil spreads more easily. Motor oils are ranked by viscosity. Lower viscosity oils provide less drag on the engine, but they are also used up faster than a higher-viscosity material. Q: What measures a fluid's resistance to flow? Choices: - elasticity - density - surface tension - viscosity A:
A: viscosity
