The still water of the lake in Figure above reflects almost all of the light that strikes it. The reflected light forms an image of nearby objects. An image is a copy of an object that is formed by reflected or refracted light. Q: A visual "copy" of an object that is formed by reflected or refracted light is called what? A:

Answer the following question given this paragraph: Living cells need organic molecules, known as nucleic acids . Nucleic acids are molecules that store genetic information. They pass that genetic information to the next generation. Deoxyribonucleic acid (DNA) is the nucleic acid that carries information for nearly all living cells today. DNA has done this for most of Earth's history. Ribonucleic acid (RNA) delivers genetic instructions to the location in a cell where protein is synthesized. RNA regulates protein synthesis. Some scientists think that RNA was the first replicating molecule. Q: Name the two types of nucleic acids. A:

OPTIONS:
- isoleucin and leucine
- dna ( trigraph acid ) and rna ( ribonucleic acid )
- lysine and methionine
- dna (deoxyribonucleic acid) and rna (ribonucleic acid)

Answer: dna (deoxyribonucleic acid) and rna (ribonucleic acid)

Problem: OPTIONS:
- mammals
- dinosaurs
- reptiles
- fish
Q: Answer the following question given this paragraph: The earliest vertebrates were jawless fish. They evolved about 550 million years ago. They were probably similar to modern hagfish (see Table above ). The tree diagram in Figure below summarizes how vertebrates evolved from that time forward. Q: The earliest vertebrates were jawless what? A:
Answer: fish

Problem:OPTIONS:
- path
- positive
- simple
- opposite

Answer the following question given this paragraph: Sodium and chloride ions have equal but opposite charges. Opposite electric charges attract each other, so sodium and chloride ions cling together in a strong ionic bond. You can see this in row 2 of the Figure above . (Brackets separate the ions in the diagram to show that the ions in the compound do not actually share electrons. ) When ionic bonds hold ions together, they form an ionic compound. The compound formed from sodium and chloride ions is named sodium chloride. It is commonly called table salt. You can see an animation of sodium chloride forming at this URL: http://www. visionlearning. com/library/module_viewer. php?mid=55. Q: Sodium and chloride ions have equal but what charges? A:
****
A: opposite

Answer the following question given this paragraph: Like mitochondria, plastids contain their own DNA. Therefore, according to endosymbiotic theory, plastids may also have evolved from ancient, free-living prokaryotes that invaded larger prokaryotic cells. If so, they allowed early eukaryotes to make food and produce oxygen. Q: Like mitochondria, plastids contain their own what? A:
OPTIONS:
- riboflavin
- bacteria
- molecule
- dna
dna
