input: OPTIONS:
- iris
- pupil
- meniscus
- lens Now, answer this question: Answer the following question given this paragraph: Light from objects at different distances is focused by the lens of the eye. Muscles in the eye control the shape of the lens so the light is focused on the back of the eye no matter how far the object is from the lens. Q: Light from objects at different distances is focused by what part of the eye? A:
A:
output: lens

Answer the following question given this paragraph: Innate behavior is any behavior that occurs naturally in all the animals of a given species. It doesn't have to be learned, and it occurs in the same way in all members of the species. Examples of innate behaviors include the waggle dance in honeybees and the grasp reflex in human babies. Q: What type of behavior occurs naturally in all animals of a given species? A:

OPTIONS:
- stimulated
- learned
- acquired
- innate

Answer: innate

Problem: OPTIONS:
- magnetism
- sound
- minerals

Q: Answer the following question given this paragraph: Conceptual Questions 33.3 Accelerators Create Matter from Energy 1. The total energy in the beam of an accelerator is far greater than the energy of the individual beam particles. Why isn't this total energy available to create a single extremely massive particle? 2. Synchrotron radiation takes energy from an accelerator beam and is related to acceleration. Why would you expect the problem to be more severe for electron accelerators than proton accelerators? 3. What two major limitations prevent us from building high-energy accelerators that are physically small? 4. What are the advantages of colliding-beam accelerators? What are the disadvantages?. Q: Colliding-beam accelerators create matter from what? A:
Answer: energy

Answer the following question given this paragraph: Recall that the cell membrane is semipermeable. It does not allow everything to pass through. Some molecules can pass easily through your cell membranes, while others have more difficulty. Sometimes molecules need the help of special transport proteins to move across the cell membrane. Some molecules even need an input of energy to help get them across the cell membrane. The movement of molecules across a membrane without the input of energy is known as passive transport . When energy (ATP) is needed, the movement is known as active transport . Active transport moves molecules against their concentration gradient, from an area of low concentration to an area of high concentration. Q: What do you call the movement of molecules across a membrane without the input of energy? A:
OPTIONS:
- obvious transport
- reactive transport
- active transport
- passive transport

Answer:
passive transport
