Nature selects the variations that are most useful. Therefore, he called this type of selection natural selection. Q: Darwin coined what term to refer to an organism's relative ability to survive and produce fertile offspring? Choices: - momentum - metabolism - strength - fitness A:
fitness
Answer the following question given this paragraph: What is the difference between distance and displacement? Whereas displacement is defined by both direction and magnitude, distance is defined only by magnitude. Displacement is an example of a vector quantity. Distance is an example of a scalar quantity. A vector is any quantity with both magnitude and direction. Other examples of vectors include a velocity of 90 km/h east and a force of 500 newtons straight down. The direction of a vector in one-dimensional motion is given simply by a plus. Q: Displacement is a vector quantity, which means it has both direction and what else? Choices: - radiation - rate - waves - magnitude A:
magnitude
Q: Answer the following question given this paragraph: Q: The earliest stages of spermatogenesis occur closest to the lumen of the what? Choices: - interstitial tubules - viviparous tubules - epithelium tubules - seminiferous tubules A:
A: seminiferous tubules
Question: Answer the following question given this paragraph: Did you ever hear an echo of your own voice? An echo occurs when sound waves bounce back from a hard object. The man in Figure below is trying to create an echo by shouting toward a rock wall. When the sound waves strike the rock wall, they can't pass through. Instead, they bounce back toward the man, and he hears an echo of his voice. An echo is just one example of how waves interact with matter. Q: What sound can be heard when sound waves bounce back from a hard object? Choices: - loop - eerie - boom - echo A:

Answer the following question given this paragraph: Plate movements cause continents to drift closer to the poles or the Equator. Ocean currents also shift when continents drift. All these changes can affect Earth's temperature. Q: What causes continents to drift closer to the poles or the equator? Choices: - wind - sediment movements - tidal pull - plate movements A:
**Answer**
plate movements
