Answer the following question given this paragraph: Insects are capable of a surprising range of behaviors. Most of their behaviors, such as flying and mating, are instinctive. These are behaviors that don't need to be learned. They are largely controlled by genes. However, some insect behaviors are learned. For example, ants and bees can learn where food is located and keep going back for more. Q: What types of incest behaviors are controlled by genes? Choices: - byproduct behaviors like flying and mating - psychological behaviors like flying and mating - physical behaviors like flying and mating - instinctive behaviors like flying and mating A:
instinctive behaviors like flying and mating
Answer the following question given this paragraph: The magnitude, direction, and point of application of the force are incorporated into the definition of the physical quantity called torque. Torque is the rotational equivalent of a force. It is a measure of the effectiveness of a force in changing or accelerating a rotation (changing the angular velocity over a period of time). In equation form, the magnitude of torque is defined to be. Q: What is the rotational equivalent of a force? Choices: - momentum - power - centripetal force - torque A:
torque
Q: Answer the following question given this paragraph: A circuit must be closed for electric devices such as light bulbs to work. The arrows in the diagram show the direction in which electrons flow through the circuit. The current is considered to flow in the opposite direction. Q: A circuit must be what in order for electric devices such as light bulbs to work? Choices: - open - down - cyclical - closed A:
A: closed
Question: Answer the following question given this paragraph: The control rods play an important role in the modulation of the nuclear chain reaction (usually a collision of a neutron with uranium). Each collision produces more neutrons than were present initially. If left unsupervised, the reaction would soon get out of control. Rods are commonly made of boron or a number of metals and metal alloys. The purpose of the control rods is to absorb neutrons to regulate the rate of the chain reaction so that the water does not overheat and destroy the reactor. Q: What play an important role in the modulation of the nuclear chain reaction? Choices: - radiation rods - control neutrons - particle rods - control rods A:
Answer: control rods

Answer the following question given this paragraph: Lenses make use of the refraction of light to create images. A lens is a transparent object, typically made of glass, with one or two curved surfaces. The more curved the surface of a lens is, the more it refracts light. Like mirrors, lenses may be concave or convex. Q: Lenses make use of what to create images? Choices: - envelopment of light - stimulation of light - resonance of light - refraction of light A:
**Answer**
refraction of light
(Q).
Answer the following question given this paragraph: Meteoroids are smaller than asteroids, ranging from the size of boulders to the size of sand grains. When meteoroids enter Earth's atmosphere, they vaporize, creating a trail of glowing gas called a meteor. If any of the meteoroid reaches Earth, the remaining object is called a meteorite. Q: When a meteoroid reaches earth, what is the remaining object called? Choices: - comet - meteor - orbit - meteorite A:
(A).
meteorite
