Q: 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

A: rods

input: OPTIONS:
- weight
- height
- size
- time Now, answer this question: Answer the following question given this paragraph: Calculating acceleration is complicated if both speed and direction are changing. It's easier to calculate acceleration when only speed is changing. To calculate acceleration without a change in direction, you just divide the change in velocity (represented by ) by the change in time (represented by ). The formula for acceleration in this case is:. Q: To calculate acceleration without a change in direction, you just divide the change in velocity by the change in what? A:
A:
output: time

Q: Answer the following question given this paragraph: Cell Structure The cells of protists are among the most elaborate of all cells. Most protists are microscopic and unicellular, but some true multicellular forms exist. A few protists live as colonies that behave in some ways as a group of free-living cells and in other ways as a multicellular organism. Still other protists are composed of enormous, multinucleate, single cells that look like amorphous blobs of slime, or in other cases, like ferns. In fact, many protist cells are multinucleated; in some species, the nuclei are different sizes and have distinct roles in protist cell function. Single protist cells range in size from less than a micrometer to three meters in length to hectares. Protist cells may be enveloped by animal-like cell membranes or plant-like cell walls. Others are encased in glassy silica-based shells or wound with pellicles of interlocking protein strips. The pellicle functions like a flexible coat of armor, preventing the protist from being torn or pierced without compromising its range of motion. Q: What functions like a flexible coat of armor, preventing the protist from being torn or pierced without compromising its range of motion? A:
Answer: pellicle

Problem:OPTIONS:
- muscles
- limbs
