Q: 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? A:

OPTIONS:
- lowest
- simplest
- basic
- fundamental

A: fundamental

input: OPTIONS:
- fallopian tube
- uterus
- kidney
- urethra Now, answer this question: Answer the following question given this paragraph: The penis is a cylinder-shaped organ. It contains the urethra. The urethra is a tube that carries urine out of the body. The urethra also carries sperm out of the body. Q: What tube carries urine out of the body? A:
A:
output: urethra

Answer the following question given this paragraph: 4. Ions move through the membrane to maintain electrical neutrality in the cell. In the cell illustrated above, sulfate ions will move from the copper side to the zinc side to compensate for the decrease in Cu 2+ and the increase in Zn 2+ . Q: Ions move through what to maintain electrical neutrality in the cell? A:

OPTIONS:
- the plasma
- the substrate
- the protein
- the membrane

Answer: the membrane

Problem: OPTIONS:
- cardiac system
- nervous system
- circulatory system
- cardiovascular system
Q: Answer the following question given this paragraph: The cardiovascular system consists of the heart, a network of blood vessels, and blood. Blood is a liquid tissue. The heart is a pump that keeps blood flowing through the vessels of the system. Q: Which system in the human body consists of the heart, a network of blood vessels, and blood? A:
Answer: cardiovascular system

Problem:OPTIONS:
- perspiration
- precipitation
- photosynthesis
- respiration

Answer the following question given this paragraph: The process of getting oxygen into the body and releasing carbon dioxide is called respiration. Q: What is the process of getting oxygen into the body & releasing carbon dioxide called? A:
****
A: respiration

Problem:OPTIONS:
- oxygen
- Nitrogen
- hydrogen
- carbon

Answer the following question given this paragraph: Figure 20.11 Carbon dioxide gas exists in the atmosphere and is dissolved in water. Photosynthesis converts carbon dioxide gas to organic carbon, and respiration cycles the organic carbon back into carbon dioxide gas. Long-term storage of organic carbon occurs when matter from living organisms is buried deep underground and becomes fossilized. Volcanic activity and, more recently, human emissions bring this stored carbon back into the carbon cycle. (credit: modification of work by John M. Evans and Howard Perlman, USGS). Q: Long-term storage of what element occurs when matter from living organisms is buried deep underground and becomes fossilized? A:
****
A:
carbon
