Answer the following question given this paragraph: Insects spread disease and destroy crops. However, they are essential for pollinating flowering plants. Q: What are essential for pollination, but can spread disease and destroy crops? Choices: - fruits - spiders - mice - insects A:
insects
Answer the following question given this paragraph: Q: The neck of the uterus, called the cervix, opens into what? Choices: - bladder - testicle - retina - vagina A:
vagina
Q: Answer the following question given this paragraph: In science, a theory has been repeatedly shown to be true. A theory is supported by many observations. However, a theory may be disproved if conflicting data is discovered. Many important theories have been shown to be true by many observations and experiments and are extremely unlikely to be disproved. These include the theory of plate tectonics and the theory of evolution. Q: What does a theory need to be supported by? Choices: - facts - peer reviewed journals - scientists - many observations A:
A: many observations
Question: Answer the following question given this paragraph: The nuclear envelope is a double membrane of the nucleus that encloses the genetic material. It separates the contents of the nucleus from the cytoplasm. The nuclear envelope is made of two phospholipid bilayers, an inner membrane and an outer membrane. The outer membrane is continuous with the rough endoplasmic reticulum. Many tiny holes called nuclear pores are found in the nuclear envelope. These nuclear pores help to regulate the exchange of materials (such as RNA and proteins) between the nucleus and the cytoplasm. Q: What is a double membrane of the nucleus that encloses the genetic material? Choices: - the complex envelope - the cell wall - the nuclear compression - the nuclear envelope A:
Answer: the nuclear envelope

Answer the following question given this paragraph: Caecilians are most closely related to salamanders. As you can see from Figure below , they have a long, worm-like body without legs. Caecilians evolved from a tetrapod ancestor, but they lost their legs during the course of their evolution. Q: What ancestors did caecillians evolve from? Choices: - ornithopod - arthropod - hominid - tetrapod A:
**Answer**
tetrapod

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:
**Answer**
inductance
