input: OPTIONS:
- scales
- plates
- spines
- teeth Now, answer this question: Answer the following question given this paragraph: Mammalian teeth are also important for digestion. The four types of teeth are specialized for different feeding functions, as shown in Figure below . Together, the four types of teeth can cut, tear, and grind food. This makes food easier and quicker to digest. Q: In mammals, four specialized types of what serve to cut, tear, and grind food? A:
A:
output: teeth

input: OPTIONS:
- frictional forces
- tension forces
- hydrodynamic forces
- centripetal forces Now, answer this question: Answer the following question given this paragraph: In the absence of a net force, objects move in a straight line. If they turn that is, if their velocity changes, even only in direction there must be an applied force. Forces which cause objects to turn around continuously in a circle are known as centripetal forces. When an object moves in a circle its velocity at any particular instant points in a direction tangent to the circle. The acceleration points towards the center of the circle, and so does the force acting on it. This is only natural, when you think about it if you feel a force pushing you towards your left as you walk forward, you will walk in a circle, always turning left. Q: Forces which cause objects to turn around continuously in a circle are known as? A:
A:
output: centripetal forces

input: OPTIONS:
- they are half
- they are double
- they are triple
- they are equal Now, answer this question: Answer the following question given this paragraph: In an electrically neutral atom, the number of protons equals the number of electrons. Q: How does the number of protons compare to the number of electrons in an electrically neutral atom? A:
A:
output:
they are equal
