Question: Answer the following question given this paragraph: 26.3 Color and Color Vision The eye has four types of light receptorsrods and three types of color-sensitive cones. The rods are good for night vision, peripheral vision, and motion changes, while the cones are responsible for central vision and color. We perceive many hues, from light having mixtures of wavelengths. A simplified theory of color vision states that there are three primary colors, which correspond to the three types of cones, and that various combinations of the primary colors produce all the hues. The true color of an object is related to its relative absorption of various wavelengths of light. The color of a light source is related to the wavelengths it produces. Color constancy is the ability of the eye-brain system to discern the true color of an object illuminated by various light sources. The retinex theory of color vision explains color constancy by postulating the existence of three retinexes or image systems, associated with the three types of cones that are compared to obtain sophisticated information. Q: The four types of light receptors include different types of cones and what else? A:
OPTIONS:
- quarks
- neutrons
- joints
- rods
Answer: rods

input with options: Answer the following question given this paragraph: character increases. Silicates contain anions that consist of only silicon and oxygen. Aluminosilicates are formed by replacing some of the Si atoms in silicates by Al atoms; aluminosilicates with threedimensional framework structures are called zeolites. Nitrides formed by reacting silicon or germanium with nitrogen are strong, hard, and chemically inert. The hydrides become thermodynamically less stable down the group. Moreover, as atomic size increases, multiple bonds between or to the group 14 elements become weaker. Silicones, which contain an SiO backbone and SiC bonds, are high-molecular-mass polymers whose properties depend on their compositions. Q: Aluminosilicates are formed by replacing some of the si atoms in silicates by which atoms? A:
OPTIONS:
- fe
- ce
- ad
- al
output: al

Q: Answer the following question given this paragraph: Color is probably the easiest property to observe. Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a golden color and think it is gold. But it might actually be pyrite, or "fool's gold," which is made of iron and sulfide. It contains no gold atoms. Q: Although it is the easiest to observe, what property is not ideal as a sole way to identify minerals? A:

OPTIONS:
- temperature
- density
- composition
- color

A: color

input: OPTIONS:
- electron
- proton
- orbit
- the nucleus Now, answer this question: Answer the following question given this paragraph: A neutron is one of three main particles that make up the atom. It is found in the nucleus and is neutral in electric charge. It has about the same mass and diameter as a proton. Neutrons are found in all atoms except for most atoms of hydrogen. Q: Where in the atom is a neutron found? A:
A:
output: the nucleus

Answer the following question given this paragraph: Eris is the largest known dwarf planet in the solar system. It is 27 percent larger than Pluto ( Figure above ). Like Pluto and Makemake, Eris is in the Kuiper belt. But Eris is about three times farther from the Sun than Pluto. Because of its distance, Eris was not discovered until 2005. Early on, it was thought that Eris might be the tenth planet. Its discovery helped astronomers realize that they needed a new definition of "planet. " Eris has a small moon that orbits Eris once about every 16 days. Q: What large dwarf planet in our solar system was only discovered in 2005? A:

OPTIONS:
- artemis
- Cerus
- zeus
- eris

Answer: eris

Q: Answer the following question given this paragraph: Figure 19.24 Coral is the foundation species of coral reef ecosystems. (credit: Jim E. Maragos, USFWS). Q: What is the foundation species of coral reef ecosystems? A:

OPTIONS:
- anemones
- crystals
- molluscs
- coral

A:
coral
