Q: Answer the following question given this paragraph: Saturated hydrocarbons are given the general name of alkanes. The name of specific alkanes always ends in ane and has a prefix to indicate how many carbon atoms it has. Q: Saturated hydrocarbons are given the general name of what? Choices: - enzymes - carbohydrates - lipids - alkanes A:

Q: Answer the following question given this paragraph: One common application of inductance is used in traffic lights that can tell when vehicles are waiting at the intersection. An electrical circuit with an inductor is placed in the road under the place a waiting car will stop over. The body of the car increases the inductance and the circuit changes sending a signal to the traffic lights to change colors. Similarly, metal detectors used for airport security employ the same technique. A coil or inductor in the metal detector frame acts as both a transmitter and a receiver. The pulsed signal in the transmitter coil induces a signal in the receiver. The self-inductance of the circuit is affected by any metal object in the path. Such detectors can be adjusted for sensitivity and also can indicate the approximate location of metal found on a person. (But they will not be able to detect any plastic explosive such as that found on the "underwear bomber. ") See Figure 23.43. Q: Metal detectors used for airport security work on which principle? Choices: - electricity - inertia - conductivity - inductance A:
A: inductance

Q: Answer the following question given this paragraph: Energy is a property of matter that is defined as the ability to do work. The concept of energy is useful for explaining and predicting most natural phenomena, and it is the foundation for an understanding of biology. All living organisms need energy to grow and reproduce. However, energy can never be created nor destroyed. Energy can only be transformed. That is, energy is always conserved. This is called the law of conservation of energy . Therefore, organisms cannot create the energy they need. Instead, they must obtain energy from the environment. Organisms also cannot destroy or use up the energy they obtain. They can only change it from one form to another. Organisms will either use their energy (for metabolism) or release it to the environment as heat. Q: What property of matter is defined as the ability to do work and is required by all living organisms in order to grow and reproduce? Choices: - growth - food - heating - energy A:
A: energy

Q: Answer the following question given this paragraph: Q: What kind of symmetry do echinoderm larvae have? Choices: - internal - radial - spherical - bilateral A:
