Answer the following question given this paragraph: 46.3 | Biogeochemical Cycles By the end of this section, you will be able to: Discuss the biogeochemical cycles of water, carbon, nitrogen, phosphorus, and sulfur Explain how human activities have impacted these cycles and the potential consequences for Earth Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for chemoautotrophs) and leaving as heat during the many transfers between trophic levels. However, the matter that makes up living organisms is conserved and recycled. The six most common elements associated with organic moleculescarbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfurtake a variety of chemical forms and may exist for long periods in the atmosphere, on land, in water, or beneath the Earth's surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle. Water contains hydrogen and oxygen, which is essential to all living processes. The hydrosphere is the area of the Earth where water movement and storage occurs: as liquid water on the surface and beneath the surface or frozen (rivers, lakes, oceans, groundwater, polar ice caps, and glaciers), and as water vapor in the atmosphere. Carbon is found in all organic macromolecules and is an important constituent of fossil fuels. Nitrogen is a major component of our nucleic acids and proteins and is critical to human agriculture. Phosphorus, a major component of nucleic acid (along with nitrogen), is one of the main ingredients in artificial fertilizers used in agriculture and their associated environmental impacts on our surface. Q: What do we call the recycling of inorganic matter between living organisms and their environment? Choices: - phosphorus cycle - nutrient cycle - water cycle - biogeochemical cycle A:
biogeochemical cycle

Answer the following question given this paragraph: Figure 33.16 Adipose is a connective tissue is made up of cells called adipocytes. Adipocytes have small nuclei localized at the cell edge. Q: Adipose is a connective tissue made up of cells called what? Choices: - keratinocytes - oocytes - hepatocytes - adipocytes A:
(Answer)
adipocytes
Ques: Answer the following question given this paragraph: Seed plants are vascular plants that reproduce with seeds. Modern seed plants are called spermatophytes. Seeds allow the plants to reproduce without water. Most vascular plants today are seed plants. Q: What is the term for vascular plants that reproduce with seeds? Choices: - Reproductive Plants - mother plants - strain plants - seed plants A:
Ans: seed plants
(Q).
Answer the following question given this paragraph: A unit cell is the smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire crystal. A crystal can be thought of as the same unit cell repeated over and over in three dimensions. The Figure below illustrates the relationship of a unit cell to the entire crystal lattice. Q: What is the smallest portion of a crystal lattice? Choices: - ionic cell - function cell - element cell - unit cell A:
(A).
unit cell
Ques:Answer the following question given this paragraph: Q: What is the name of the fungi that are ubiquitous in lakes and soil? Choices: - eomycota - zygomycota - sporozoans - chytrids A:

Ans:chytrids
Question: Answer the following question given this paragraph: The Carboniferous Period : Next, during the Carboniferous Period (360290 million years ago), widespread forests of huge plants left massive deposits of carbon that eventually turned to coal. The first amphibians evolved to move out of the water and colonize land, but they had to return to the water to reproduce. Soon after amphibians arose, the first reptiles evolved. They were the first animals that could reproduce on dry land. Q: During what period on earth was coal formed? Choices: - Mesozoic - Neoproterozoic - Neoproterozoic era - the carboniferous period A:
Answer:
the carboniferous period
