Answer the following question given this paragraph: The rate of evolution depends on how many of an organism's genes have changed over a period of time. Evolution is usually so gradual that we do not see the change for many, many generations. The rate of evolution also depends on the generation time of a particular species. Q: The rate of what process depends on how many of an organism's genes have changed over a period of time and on the generation time of a particular species? A:

OPTIONS:
- digestion
- respiration
- photosynthesis
- evolution

Answer: evolution

Problem: OPTIONS:
- helpful
- consistent
- active
- constructive
Q: Answer the following question given this paragraph: 2t = n / 2, 3 n / 2, 5 n / 2, . To know whether interference is constructive or destructive, you must also determine if there is a phase change upon reflection. Thin film interference thus depends on film thickness, the wavelength of light, and the refractive indices. For white light incident on a film that varies in thickness, you will observe rainbow colors of constructive interference for various wavelengths as the thickness varies. Example 27.7 Soap Bubbles: More Than One Thickness can be Constructive (a) What are the three smallest thicknesses of a soap bubble that produce constructive interference for red light with a wavelength of 650 nm? The index of refraction of soap is taken to be the same as that of water. (b) What three smallest thicknesses will give destructive interference? Strategy and Concept Use Figure 27.33 to visualize the bubble. Note that water). There is a. Q: Different types of interference include destructive and what else? A:
Answer: constructive

- ocean floor

Answer the following question given this paragraph: Scientists have learned a lot about the ocean floor. For example, they know that Earth's tallest mountains and deepest canyons are on the ocean floor. The major features on the ocean floor are described below. They are also shown in Figure below . Q: Surprisingly, where would you find the earth's tallest mountains and deepest canyons? A:
****
A: ocean floor

Answer the following question given this paragraph: Barrier islands provide natural protection to shorelines. Storm waves strike the barrier island before they reach the shore. People also build artificial barriers, called breakwaters . Breakwaters also protect the shoreline from incoming waves. You can see an example of a breakwater in Figure below . It runs parallel to the coast like a barrier island. Q: What kind of islands provide natural protection to shorelines? A:
OPTIONS:
- patch islands
- locational islands
- edge islands
- barrier islands
barrier islands
