Answer the following question given this paragraph: Squamous Cell Carcinoma Squamous cell carcinoma is a cancer that affects the keratinocytes of the stratum spinosum and presents as lesions commonly found on the scalp, ears, and hands (Figure 5.19). It is the second most common skin cancer. The American Cancer Society reports that two of 10 skin cancers are squamous cell carcinomas, and it is more aggressive than basal cell carcinoma. If not removed, these carcinomas can metastasize. Surgery and radiation are used to cure squamous cell carcinoma. Q: What is the second most common skin cancer? Choices: - basal cell carcinoma - melanoma - precancerous cell carcinoma - squamous cell carcinoma A:
squamous cell carcinoma

Q: In seedless vascular plants such as ferns, the sporophyte releases spores from the undersides of what basic plant structures? Choices: - roots - fruits - stems - leaves A:
leaves
Q: Answer the following question given this paragraph: Predation is a relationship in which members of one species consume members of another species. The consuming species is called the predator. The species that is consumed is called the prey. In Figure below , the wolves are predators, and the moose is their prey. Q: What do you call the relationship in which members of one species consume members of another species? Choices: - parasitism - competition - exploitation - predation A:
A: predation
Question: Answer the following question given this paragraph: Though the above fruit may not result, it would be nice to scientifically predict what would result. Predicting the possible genotypes and phenotypes from a genetic cross is often aided by a Punnett square. Q: Predicting the possible genotypes and phenotypes from a genetic cross is often aided by a what? Choices: - balusters square - dinobot square - axle square - punnett square A:
Answer: punnett square

Answer the following question given this paragraph: A fluorescent light bulb produces visible light by fluorescence. Fluorescence occurs when a substance absorbs shorter-wavelength ultraviolet light and then gives off the energy as visible light. The compact fluorescent light bulb (CFL) in the Figure below contains mercury gas that gives off ultraviolet light when electricity passes through it. The inside of the bulb is coated with a substance called phosphor. Phosphor absorbs the ultraviolet light and then gives off most of the energy as visible light. Q: What light-producing process occurs when a substance absorbs shorter-wavelength ultraviolet light and then gives off the energy as visible light? Choices: - candescence - resistance - luminescence - fluorescence A:
**Answer**
fluorescence

Answer the following question given this paragraph: Did you ever wonder what happens to a candle when it burns? A candle burning is a chemical change in matter. In a chemical change, one type of matter changes into a different type of matter, with different chemical properties. Chemical changes occur because of chemical reactions. You can see more examples of chemical changes at this URL: http://www. youtube. com/watch?v=66kuhJkQCVM . Q: Chemical changes occur because of what? Choices: - liquid reactions - evaporation - toxic reactions - chemical reactions A:
