(03.01 MC) Loggerhead turtles need an incubation temperature between about 28 and 32 degrees Celsius. When temperatures are higher, more female turtles are produced. When temperatures are lower, more males are produced. When the temperatures exceed this range, the offspring don’t develop and die. Scientists have observed that, in Florida, 90 percent of the turtles born are females. If global climate change continues, what is the best prediction that can be made based on these observations? (3 points)

(02.02 LC)Transmission electron microscopes are best for viewing

(01.01 MC) A Spanish scientist observes that salmon produce more eggs when grown in warmer aquariums. He asks his colleague in the United States to conduct the same experiment using the same aquarium equipment. Should he expect the results to be similar? (3 points)

(02.01 MC)Which of the following best explains how hydrogen bonding affects the heat of vaporization for water?

(03.01 LC)Mutagens, such as pollutants, and UV light can cause mutations in DNA to occur at a higher rate than normal. These mutations may be beneficial in some cases, but often they lead to cancer. Which of the following best describes how cancer cells affect the body?

(01.01 MC)Jason and Matt have developed a new computerized timer for recording race times. Which of the following would be the best way to confirm the timer’s accuracy?

(02.05 MC)Michaela would like to reduce her risk of skin cancer. To help reduce her risk, she can do all of the following except

(03.06 MC)A type of plant that produces red flowers is crossed with a plant that produces white flowers. The alleles for flower color exhibit incomplete dominance, and all of their offspring have pink flowers. If two of the pink-flowered offspring were crossed, which of the following ratios of red, pink, and white flowers would you find in their offspring?

(03.01 LC)Mutagens, such as pollutants, and UV light can cause mutations in DNA to occur at a higher rate than normal. These mutations may be beneficial in some cases, but often they lead to cancer. Which of the following best describes how cancer cells affect the body?

(01.01 MC) Students in a high school Marine Science class are learning about the scientific process. Four students were asked to write a testable prediction about deep-sea vents found in the ocean. Their responses are shown in the chart. Student Response Jin Deep-sea vents are too deep. Elizabeth Deep-sea vents are more interesting than caves. Carly Interest in deep-sea vents will decrease in the future. Raymond Ocean surface temperatures are warmer than water at deep-sea vents. Which student’s prediction is the most testable using the scientific process? (3 points)
