Answer the following question given this paragraph: Figure 6.11 The frictional force supplies the centripetal force and is numerically equal to it. Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the F c , the smaller the radius of curvature r and the sharper the curve. The second curve has the same v , but a larger. Q: What force is perpendicular to velocity and causes uniform circular motion? Choices: - centripetal torque - circular friction - tangential force - centripetal force A:
centripetal force

Answer the following question given this paragraph: Migration Migration is the long-range seasonal movement of animals. It is an evolved, adapted response to variation in resource availability, and it is a common phenomenon found in all major groups of animals. Birds fly south for the winter to get to warmer climates with sufficient food, and salmon migrate to their spawning grounds. The popular 2005 documentary March of the Penguins followed the 62-mile migration of emperor penguins through Antarctica to bring food back to their breeding site and to their young. Wildebeests (Figure 45.35) migrate over 1800 miles each year in search of new grasslands. Q: What evolved, adapted response to resource availability is the long-range seasonal movement of animals? Choices: - changing - Stagnation - regulating - migration A:
(Answer)
migration

(Q).
Answer the following question given this paragraph: Imagine scuba diving and coming upon a jellyfish. Would you be startled if the jellyfish suddenly started to glow with bright yellow light, like the jellyfish in the picture above? If so, then the jellyfish would have done its job. Jellyfish give off light to startle possible predators. The light they emit is visible light. Q: What do jellyfish give off to startle possible predators? Choices: - energy - plankton - electricity - light A:
(A).
light
Ques:Answer the following question given this paragraph: A chemical reaction is a process in which some substances, called reactants, change into different substances, called products. During the reaction, chemical bonds break in the reactants and new chemical bonds form in the products. Q: What type of reaction is a process in which some substances, called reactants, change into different substances, called products? Choices: - reversible reaction - physical reaction - toxic reaction - chemical reaction A:

Ans:chemical reaction
Ques:Answer the following question given this paragraph: Vertebrates reproduce sexually, and almost all of them have separate male and female sexes. Generally, aquatic species have external fertilization, whereas terrestrial species have internal fertilization. Can you think of a reason why aquatic and terrestrial vertebrates differ in this way?. Q: In which way do vertebrates reproduce? Choices: - bisexually - unisexually - asexually - sexually A:

Ans:
sexually
