Answer the following question given this paragraph: Lumbar Vertebrae Lumbar vertebrae carry the greatest amount of body weight and are thus characterized by the large size and thickness of the vertebral body (Figure 7.28). They have short transverse processes and a short, blunt spinous process that projects posteriorly. The articular processes are large, with the superior process facing backward and the inferior facing forward. Q: Which vertebrae carry the greatest amount of body weight and are thus characterized by the large size and thickness of the vertebral body? Choices: - artery vertebrae - invertebrae - thickness vertebrae - lumbar vertebrae A:
lumbar vertebrae
Answer the following question given this paragraph: Clearing land for agriculture and development is a major cause of habitat destruction. Within the past 100 years, the amount of total land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Agriculture alone has cost the United States half of its wetlands ( Figure below ) and almost all of its tallgrass prairies. Native prairie ecosystems, with their thick fertile soils, deep-rooted grasses, diversity of colorful flowers, burrowing prairie dogs, and herds of bison and other animals, have virtually disappeared ( Figure below ). Q: Clearing land for agriculture and development is a major cause of what negative result? Choices: - water destruction - human destruction - mineral destruction - habitat destruction A:
habitat destruction
Q: Answer the following question given this paragraph: Earth is warmed by energy that radiates from the sun. Earth radiates some of the energy back into space. Greenhouse gases (GHGs) trap much of the re-radiated energy, causing an increase in the temperature of the atmosphere close to the surface. Q: What is the major source of warmth for earth? Choices: - the Moon - seasons - equator - the sun A:
A: the sun
Question: Answer the following question given this paragraph: 19.3 The Human Population Earth's human population is growing exponentially. Humans have increased their carrying capacity through technology, urbanization, and harnessing the energy of fossil fuels. The age structure of a population allows us to predict population growth. Unchecked human population growth could have dire long-term effects on human welfare and Earth's ecosystems. Q: Human population is growing exponentially and humans have increased what normally limiting factor through technology, urbanization, and harnessing the energy of fossil fuels? Choices: - zero population growth - mass extinction - habitat loss - carrying capacity A:
Answer: carrying capacity
