Answer the following question given this paragraph: Ray-finned fish include the majority of living fish species. including goldfish, tuna, salmon, perch, and cod. They have a bony endoskeleton and a swim bladder. Their thin fins consist of webs of skin over flexible bony rays, or spines. The fins lack muscle, so their movements are controlled by muscles in the body wall. You can compare their ray fins with the fleshy fins of lobe-finned fish in Figure below . Q: Goldfish, tuna, salmon, perch, and cod are examples of which group of fish? A:
OPTIONS:
- spiny-lobed fish
- cartilaginous fish
- bony fish
- ray-finned fish
ray-finned fish

Answer the following question given this paragraph: Lipids consist only or mainly of carbon, hydrogen, and oxygen. Both fats and oils are made up of long chains of carbon atoms that are bonded together. These chains are called fatty acids. Fatty acids may be saturated or unsaturated. In the Figure below you can see structural formulas for two small fatty acids, one saturated and one unsaturated. Q: Both fats and oils are made up of long chains of carbon atoms that are bonded together. what are these chains called? A:
OPTIONS:
- amino acids
- metabolic acids
- nucleic acids
- fatty acids
fatty acids

Answer the following question given this paragraph: The transfer of electrons from the van de Graaff generator to the man is an example of conduction. Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons. A van de Graff generator produces a negative charge on its dome, so it tends to give up electrons. Human hands are positively charged, so they tend to accept electrons. Therefore, electrons flow from the dome to the man's hand when they are in contact. Q: A van de graff generator produces what type of charge on its dome, causing the tendency to give up electrons? A:
OPTIONS:
- positive charge
- similar charge
- no charge
- negative charge
negative charge
