Answer the following question given this paragraph: Bones are far from static, or unchanging. Instead, they are dynamic, living tissues that are constantly being reshaped. Under the direction of osteocytes, osteoblasts continuously build up bone, while osteoclasts continuously break it down. You can watch an animated video of these processes in bone at http://www. youtube. com/watch?v=yENNqRJ2mu0 . Q: Bones are far from static, or unchanging. instead, they are what? Choices: - continuous - stable - fluid - dynamic A:
dynamic
Q: Answer the following question given this paragraph: Ozone near the ground harms human health. Ground-level ozone is a pollutant. But the ozone layer in the stratosphere protects us from harmful solar rays. That's why people were alarmed in the 1980s to learn that there was a hole in the ozone layer. Q: When did we learn there was a hole in the ozone layer? Choices: - 1950s - 1970s - 1990's - 1980s A:
A: 1980s
Question: Answer the following question given this paragraph: 27.1 | Features of the Animal Kingdom By the end of this section, you will be able to: List the features that distinguish the kingdom Animalia from other kingdoms Explain the processes of animal reproduction and embryonic development Describe the roles that Hox genes play in development Even though members of the animal kingdom are incredibly diverse, most animals share certain features that distinguish them from organisms in other kingdoms. All animals are eukaryotic, multicellular organisms, and almost all animals have a complex tissue structure with differentiated and specialized tissues. Most animals are motile, at least during certain life stages. All animals require a source of food and are therefore heterotrophic, ingesting other living or dead organisms; this feature distinguishes them from autotrophic organisms, such as most plants, which synthesize their own nutrients through photosynthesis. As heterotrophs, animals may be carnivores, herbivores, omnivores, or parasites (Figure 27.2ab). Most animals reproduce sexually, and the offspring pass through a series of developmental stages that establish a determined and fixed body plan. The body plan refers to the morphology of an animal, determined by developmental cues. Q: Because all animals require an external source of what, they are called heterotrophic? Choices: - fuel - energy - water - food A:
Answer: food

Answer the following question given this paragraph: Many soil scientists work both in an office and in the field. According to the United States Department of Agriculture (USDA): "a soil scientist needs good observation skills to analyze and determine the characteristics of different types of soils. Soil types are complex and the geographical areas a soil scientist may survey are varied. Aerial photos or various satellite images are often used to research the areas. Computer skills and geographic information systems (GIS) help the scientist to analyze the multiple facets [1] of geomorphology, topography, vegetation, and climate to discover the patterns left on the landscape. " Soil scientists play a key role in understanding the soil's past, analyzing present conditions, and making recommendations for future soil-related practices. Q: What kind of scientist is concerned with facets of geomorphology, topography, vegetation, and climate? Choices: - geophysicist - atstronomer - geologist - soil scientist A:
(Answer)
soil scientist
