Answer the following question given this paragraph: Speed just takes distance and time into account. How might direction be considered as well?. Q: Speed takes distance and what else into account? A:
OPTIONS:
- gravity
- matter
- energy
- time

Answer: time

Question: Answer the following question given this paragraph: Gravity near the Earth pulls an object downwards toward the surface of the Earth with an acceleration of . In the absence of air resistance, all objects will fall with the same acceleration. The letter is used as the symbol for the acceleration of gravity. When talking about an object's acceleration, whether it is due to gravity or not, the acceleration of gravity is sometimes used as a unit of measurement where . So an object accelerating at 2g's is accelerating at or. Q: What force pulls object downwards to the earth? A:
OPTIONS:
- momentum
- kinetic energy
- motion
- gravity
Answer: gravity

input with options: Answer the following question given this paragraph: Wind energy is energy provided by the blowing wind. Wind turbines, like those in Figure above , can turn wind energy into electricity. The wind blows because of differences in heating of Earth's atmosphere by the sun. There will never be a shortage of wind. Q: What do wind turbines turn wind energy into? A:
OPTIONS:
- hydrogen
- carbon
- oxygen
- electricy
output: electricy

Q: Answer the following question given this paragraph: When lactose is available, a lactose metabolite called allolactose binds to the allosteric site on the repressor. This interaction causes a conformational change in the repressor shape and the repressor falls off the operator, allowing RNA polymerase to bind to the promoter and initiate transcription. Allolactose is called an inducer because it turns on, or induces the expression of the lac genes. Q: Which inducer turns on the expression of the lac genes? A:

OPTIONS:
- xerophyte
- glucose
- galactose
- allolactose

A: allolactose

input: OPTIONS:
- sunlight
- warmth
- wind
- stimuli Now, answer this question: Answer the following question given this paragraph: All living things can sense and respond to stimuli in their environment. Stimuli might include temperature, light, or gravity. Q: What can all living things sense and respond to in their environment? A:
A:
output: stimuli

Question: Answer the following question given this paragraph: 10.3 Muscle Fiber Contraction and Relaxation A sarcomere is the smallest contractile portion of a muscle. Myofibrils are composed of thick and thin filaments. Thick filaments are composed of the protein myosin; thin filaments are composed of the protein actin. Troponin and tropomyosin are regulatory proteins. Muscle contraction is described by the sliding filament model of contraction. ACh is the neurotransmitter that binds at the neuromuscular junction (NMJ) to trigger depolarization, and an action potential travels along the sarcolemma to trigger calcium release from SR. The actin sites are exposed after Ca++ enters the sarcoplasm from its SR storage to activate the troponin-tropomyosin complex so that the tropomyosin shifts away from the sites. The cross-bridging of myposin heads docking into actin-binding sites is followed by the "power stroke"the sliding of the thin filaments by thick filaments. The power strokes are powered by ATP. Ultimately, the sarcomeres, myofibrils, and muscle fibers shorten to produce movement. Q: What is the smallest contractile portion of a muscle? A:
OPTIONS:
- filaments
- cell
- capillary
- sarcomere
Answer:
sarcomere
