Ques: Answer the following question given this paragraph: Figure 9.3 This car is in dynamic equilibrium because it is moving at constant velocity. There are horizontal and vertical forces, but the net external force in any direction is zero. The applied force F app between the tires and the road is balanced by air friction, and the weight of the car is supported by the normal forces, here shown to be equal for all four tires. Q: When is a moving car said to be in dynamic equilibrium? Choices: - at rest - at homeostasis - when accelerating - zero net force A:
Ans: zero net force
(Q).
Answer the following question given this paragraph: All plants have a characteristic life cycle that includes alternation of generations . Plants alternate between haploid and diploid generations. Alternation of generations allows for both asexual and sexual reproduction. Asexual reproduction with spores produces haploid individuals called gametophytes . Sexual reproduction with gametes and fertilization produces diploid individuals called sporophytes . A typical plant's life cycle is diagrammed in Figure below . Q: The plants alternation between haploid and diploud generations allow it to do what? Choices: - reproduce asexually and simultaneously - reproduce sexually and autonomously - reproduce asexually and biologically - reproduce asexually and sexually A:
(A).
reproduce asexually and sexually
Ques:Answer the following question given this paragraph: Many pathogens that cause respiratory diseases spread by droplets in the air. Droplets are released when a person sneezes or coughs. Thousands of tiny droplets are released when a person sneezes ( Figure below ). Each droplet can contain thousands of pathogens. Viruses that cause colds and the flu can spread in this way. You may get sick if you breathe in the pathogens. Q: How many pathogens can each droplet contain? Choices: - tens - billions - hundreds - thousands A:

Ans:thousands
