Answer the following question given this paragraph: Television broadcasts also use radio waves. Sounds are encoded with frequency modulation, and pictures are encoded with amplitude modulation. The encoded radio waves are broadcast from a TV tower like the one in Figure below . When the waves are received by television sets, they are decoded and changed back to sounds and pictures. Q: What are groups of tens to hundreds of thousands of stars held tightly together by gravity called? Choices: - elliptical clusters - elongated clusters - galaxy - globular clusters A:
globular clusters
Answer the following question given this paragraph: Unsaturated fats are found mainly in plant foods, such as vegetable oil, olive oil, and nuts. Unsaturated lipids are also found in fish, such as salmon. Unsaturated lipids are needed in small amounts for good health. Most lipids in your diet should be unsaturated. Q: Most lipids in your diet should be what type, found mainly in plant sources and also in fish? Choices: - fat - aromatic - saturated - unsaturated A:
unsaturated
Q: Answer the following question given this paragraph: 34.1 | Digestive Systems By the end of this section, you will be able to: Explain the processes of digestion and absorption Compare and contrast different types of digestive systems Explain the specialized functions of the organs involved in processing food in the body Describe the ways in which organs work together to digest food and absorb nutrients Animals obtain their nutrition from the consumption of other organisms. Depending on their diet, animals can be classified into the following categories: plant eaters (herbivores), meat eaters (carnivores), and those that eat both plants and animals (omnivores). The nutrients and macromolecules present in food are not immediately accessible to the cells. There are a number of processes that modify food within the animal body in order to make the nutrients and organic molecules accessible for cellular function. As animals evolved in complexity of form and function, their digestive systems have also evolved to accommodate their various dietary needs. Q: Animals that have feeding patterns that are somewhere between that of herbivores and carnivores can be called what? Choices: - insectivores - nematodes - megavores - omnivores A:
A: omnivores
Question: Answer the following question given this paragraph: Diffusion is the movement of a substance from an area of a higher amount toward an area of lower amount. A concentration gradient initially exists across the cell membrane. Equilibrium is reached when there is an equal amount of the substance on both sides of the membrane. Q: What do you call the movement of a substance from an area of a higher amount toward an area of lower amount? Choices: - filtration - extraction - precipitation - diffusion A:
Answer: diffusion

Answer the following question given this paragraph: Electromagnetic waves are waves that carry energy through matter or space as vibrating electric and magnetic fields. Electromagnetic waves have a wide range of wavelengths and frequencies. Sunlight contains the complete range of wavelengths of electromagnetic waves, which is called the electromagnetic spectrum. The Figure below shows all the waves in the spectrum. Q: What type of waves carry energy through matter or space as vibrating electric and magnetic fields? Choices: - light waves - mechanical waves - sound waves - electromagnetic waves A:
(Answer)
electromagnetic waves
