Q: Answer the following question given this paragraph: Birds reproduce sexually and have separates sexes. Fertilization occurs internally, so males and females must mate. Many bird species have special behaviors, such as unique songs or visual displays, for attracting mates. These special behaviors are called courtship. The white peacock in Figure below is putting on a stunning display of his amazing tail feathers to court a mate. Q: What are the special mating behaviors in birds called? A:
Answer: courtship

Problem:OPTIONS:
- solar fission
- nuclear fission
- combustion
- nuclear fusion

Answer the following question given this paragraph: Figure 32.19 Nuclear fusion in the Sun converts hydrogen nuclei into helium; fusion occurs primarily at the boundary of the helium core, where temperature is highest and sufficient hydrogen remains. Energy released diffuses slowly to the surface, with the exception of neutrinos, which escape immediately. Energy production remains stable because of negative feedback effects. Q: What process converts the sun's hydrogen nuclei into helium? A:
****
A: nuclear fusion

Answer the following question given this paragraph: Electric devices, such as lights and household appliances, change electric current to other forms of energy. For example, an electric stove changes electric current to thermal energy. Other common devices, such as mobile phones and computers, use electric current for another purpose: to encode information. A message encoded this way is called an electronic signal , and the use of electric current for this purpose is called electronics . For an overview of electronics and electronic signals, read the short article at this URL: http://www. bbc. co. uk/scotland/learning/bitesize/standard/physics/electronics/overview_rev1. shtml . Q: An electric stove changes electric current to what form of energy? A:
OPTIONS:
- thermodynamic
- kinetic
- nuclear
- thermal
thermal

Answer the following question given this paragraph: The skin is the major organ of the integumentary system , which also includes the nails and hair. In fact, the skin is the body's largest organ, and a remarkable one at that. Consider these skin facts. The average square inch (6.5 cm 2 ) of skin has 20 blood vessels, 650 sweat glands, and more than a thousand nerve endings. It also has an incredible 60,000 pigment-producing cells. All of these structures are packed into a stack of cells that is just 2 mm thick, or about as thick as the cover of a book. Q: What organ system consists of the skin, nails and hair? A:
OPTIONS:
- nervous system
- digestive system
- endocrine system
- integumentary system

Answer: integumentary system

Question: Answer the following question given this paragraph: An alkaline battery is a variation on the zinc-carbon dry cell. The alkaline battery has no carbon rod and uses a paste of zinc metal and potassium hydroxide instead of a solid metal anode. The cathode half-reaction is the same, but the anode half-reaction is different. Q: Deficiency of what is symptomized by nausea, fatigue and dizziness, and can be triggered by excessive sweating? A:
OPTIONS:
- impurities
- salts
- calories
- electrolytes
Answer: electrolytes

input: OPTIONS:
- pressure
- fuel
- exercise
- energy Now, answer this question: Answer the following question given this paragraph: Energy is the ability to do work. When work is done, energy is transferred from one object to another. Energy can exist in different forms, such as electrical and chemical energy. Most forms of energy can also be classified as kinetic or potential energy. Q: Kinetic and potential are two forms of what? A:
A:
output:
energy
