Ques:Answer the following question given this paragraph: Human beings and other primates also have the ability to see in color. We have special cells inside our eyes that can distinguish different wavelengths of visible light. Visible light is light in the range of wavelengths that the human eye can sense. The exact wavelength of visible light determines its color. Q: What determines the color of visible light? Choices: - wavelength speed - wavelength density - molecular wavelength - exact wavelength A:

Ans:exact wavelength

Ques:Answer the following question given this paragraph: Shape of Proteins Just as a fork cannot be used to eat soup and a spoon cannot be used to spear meat, a protein's shape is essential to its function. A protein's shape is determined, most fundamentally, by the sequence of amino acids of which it is made (Figure 2.26a). The sequence is called the primary structure of the protein. Q: A protein's shape is determined, most fundamentally, by the sequence of what type of acids? Choices: - lipids - acetic - lactic - amino A:

Ans:amino

Ques:Answer the following question given this paragraph: Food Chains and Food Webs A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers. These levels are used to describe ecosystem structure and dynamics. There is a single path through a food chain. Each organism in a food chain occupies a specific trophic level (energy level), its position in the food chain or food web. In many ecosystems, the base, or foundation, of the food chain consists of photosynthetic organisms (plants or phytoplankton), which are called producers. The organisms that consume the producers are herbivores: the primary consumers. Secondary consumers are usually carnivores that eat the primary consumers. Tertiary consumers are carnivores that eat other carnivores. Higher-level consumers feed on the next lower trophic levels, and so on, up to the organisms at the top of the food chain: the apex consumers. In the Lake Ontario food chain, shown in Figure 20.4, the Chinook salmon is the apex consumer at the top of this food chain. Q: Producers, primary consumers, higher-level consumers, and decomposers are levels in what? Choices: - food model - energy chain - food flowchart - food chain A:

Ans:
food chain
