Answer the following question given this paragraph: The size and shape of the beak is related to the food the bird eats and can vary greatly among different birds. Parrots have down-curved, hooked bills, which are well-adapted for cracking seeds and nuts ( Figure below ). Hummingbirds, on the other hand, have long, thin, pointed bills, which are adapted for getting the nectar out of flowers ( Figure below ). Hawks, eagles, falcons and owls have a sharp, hooked beak. Q: What characteristic of birds is related to the food they eat? Choices: - feathers - tail - feet - beak A:
beak

understory
Ques: Answer the following question given this paragraph: Almost all surfaces reflect some of the light that strikes them. 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? Choices: - mirror - instance - photo - image A:
Ans: image

(A).
mineral nutrients
Ques:Answer the following question given this paragraph: rest after sticking together, conserving momentum. But the internal kinetic energy is zero after the collision. A collision in which the objects stick together is sometimes called a perfectly inelastic collision because it reduces internal kinetic energy more than does any other type of inelastic collision. In fact, such a collision reduces internal kinetic energy to the minimum it can have while still conserving momentum. Perfectly Inelastic Collision A collision in which the objects stick together is sometimes called "perfectly inelastic. Q: A perfectly inelastic collision reduces internal kinetic energy to the minimum it can have while still conserving what? Choices: - heat - energy - elements - momentum A:

Ans:momentum
Answer the following question given this paragraph: Just like it sounds, a wheel and axle is composed of two connected cylinders of different diameters. Since the wheel has a larger radius (distance) than the axle, the axle will always have a larger force than the wheel. The ideal mechanical advantage of a wheel and axle is dependent on the ratio between the radii:. Q: The ratio between the radii of a wheel and axle determines what? Choices: - fundamental mechanical advantage - introduced mechanical advantage - theoretical mechanical advantage - ideal mechanical advantage A:
ideal mechanical advantage
