Answer the following question given this paragraph: Given that maximum air displacements are possible at the open end and none at the closed end, there are other, shorter wavelengths that can resonate in the tube, such as the one shown in Figure 17.28. Here the standing wave has three-fourths of its wavelength in the tube, or L = (3 / 4) , so that = 4L / 3 . Continuing this process reveals a whole series of shorterwavelength and higher-frequency sounds that resonate in the tube. We use specific terms for the resonances in any system. The lowest resonant frequency is called the fundamental, while all higher resonant frequencies are called overtones. All resonant frequencies are integral multiples of the fundamental, and they are collectively called harmonics. The fundamental is the first harmonic, the first overtone is the second harmonic, and so on. Figure 17.29 shows the fundamental and the first three overtones (the first four harmonics) in a tube closed at one end. Q: The lowest resonant frequency is called the what? Choices: - lowest - simplest - basic - fundamental A:
fundamental
Answer the following question given this paragraph: 36.5 | Vision By the end of this section, you will be able to: Explain how electromagnetic waves differs from sound waves Trace the path of light through the eye to the point of the optic nerve Explain tonic activity as it is manifested in photoreceptors in the retina Vision is the ability to detect light patterns from the outside environment and interpret them into images. Animals are bombarded with sensory information, and the sheer volume of visual information can be problematic. Fortunately, the visual systems of species have evolved to attend to the most-important stimuli. The importance of vision to humans is further substantiated by the fact that about one-third of the human cerebral cortex is dedicated to analyzing and perceiving visual information. Q: About one-third of the human cerebral cortex is dedicated to analyzing and perceiving information related to what sense? Choices: - hearing - touch - taste - vision A:
vision
Q: Answer the following question given this paragraph: Blue light has a shorter wavelength than red light. Which color has the higher frequency? Which moves faster in a vacuum?. Q: Compared to red light, blue light has a shorter what? Choices: - gravity - life span - absorption - wavelength A:
A: wavelength
Question: Answer the following question given this paragraph: Q: What do electromagnetic receptors detect? Choices: - dangerous radiation - background radiation - subtle radiation - electromagnetic radiation A:
Answer: electromagnetic radiation

Answer the following question given this paragraph: Other methods of surface mining include strip mining, placer mining, and dredging. Strip mining is like open pit mining but with material removed along a strip. A quarry is a type of open-pit mine that produces rocks and minerals that are used to make buildings and roads. Q: What is the type of mining called when materials are removed along a strip? Choices: - surface mining - edge mining - pit mining - strip mining A:
**Answer**
strip mining
Q: Answer the following question given this paragraph: Q: Although it is not vital to humans, calcitonin is important for calcium homeostasis in adults of some species in what group characterized by backbones? Choices: - mammals - reptiles - invertebrates - vertebrates A:
A: vertebrates
