Answer the following question given this paragraph: Each kind of pigment absorbs specific wavelengths (colors) of light (dashed lines). Sunlight contains many different wavelengths, which you see when they separate into a rainbow. Not all colors of light are used in photosynthesis (solid line). Most plants, algae, and photosynthetic bacteria appear green because they reflect green wavelengths. Their pigments have absorbed the violet-blue and red wavelengths. The amount of photosynthesis depends on the wavelength of light available. Beta-carotene is another type of pigment that absorbs sunlight. Q: Sunlight contains many different wavelengths, which you see when they separate into what? A:
****
A: rainbow

Answer the following question given this paragraph: Like all organisms, plants detect and respond to stimuli in their environment. Unlike animals, plants can't run, fly, or swim toward food or away from danger. They are usually rooted to the soil. Instead, a plant's primary means of response is to change how it is growing. Plants also don't have a nervous system to control their responses. Instead, their responses are generally controlled by hormones , which are chemical messenger molecules. Q: Instead of a nervous system, plant responses are generally controlled by what type of molecules, which serves as chemical messengers? A:
OPTIONS:
- receptors
- enzymes
- sugars
- hormones
hormones

Answer the following question given this paragraph: Amphibians are vertebrates that exist in two worlds. They divide their time between freshwater and terrestrial habitats. They share a number of features with air-breathing lungfish, but they also differ from lungfish in many ways. One way they differ is their appendages. Amphibians are the first true tetrapods, or vertebrates with four limbs. Modern amphibians include frogs, salamanders, and caecilians, as shown Figure below . Q: Vertebrates with four limbs are also called what? A:
OPTIONS:
- Amphibians
- Birds
- Mammals
- tetrapods

Answer: tetrapods

Question: Answer the following question given this paragraph: Some of the most interesting kinds of evidence for evolution are body parts that have lost their use through evolution ( Figure below ). For example, most birds need their wings to fly. But the wings of an ostrich have lost their original use. Structures that have lost their use through evolution are called vestigial structures . They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure, or using it for a different purpose. Q: Structures that have lost their use through evolution are called _______ A:
OPTIONS:
- primordial structures
- residual structures
- symbiotic structures
- vestigial structures
Answer: vestigial structures

input with options: Answer the following question given this paragraph: Due to the difference in the distribution of charge, water is a polar molecule. Q: Due to the difference in the distribution of charge, water is what type of molecule? A:
OPTIONS:
- ionic
- uneven
- crooked
- polar
output: polar

Problem: OPTIONS:
- kinetic energy
- potential energy
- geothermal energy
- solar energy
Q: Answer the following question given this paragraph: The energy in sunlight, or solar energy, can be used to heat homes. It can also be used to produce electricity in solar cells. However, solar energy may not be practical in areas that are often cloudy. Q: The energy in sunlight is also known as what kind of energy? A:
Answer:
solar energy
