Answer the following question given this paragraph: Introduction Coral reefs are home to about 25% of all marine species. They are being threatened by climate change, oceanic acidification, and water pollution, all of which change the composition of the solution we know as seawater. Dissolved oxygen in seawater is critical for sea creatures, but as the oceans warm, oxygen becomes less soluble. As the concentration of carbon dioxide in the atmosphere increases, the concentration of carbon dioxide in the oceans increases, contributing to oceanic acidification. Coral reefs are particularly sensitive to the acidification of the ocean, since the exoskeletons of the coral polyps are soluble in acidic solutions. Humans contribute to the changing of seawater composition by allowing agricultural runoff and other forms of pollution to affect our oceans. Solutions are crucial to the processes that sustain life and to many other processes involving chemical reactions. In this chapter, we will consider the nature of solutions, and examine factors that determine whether a solution will form and what properties it may have. In addition, we will discuss colloidssystems that resemble solutions but consist of dispersions of particles somewhat larger than ordinary molecules or ions. Q: Dissolved oxygen in seawater is critical for sea creatures, but as the oceans warm, oxygen becomes less what? A:
OPTIONS:
- insoluble
- abundant
- saturated
- soluble
soluble

Answer the following question given this paragraph: The differences in the biomes are due to differences in the abiotic factors , especially climate. Climate is the typical weather in an area over a long period of time. The climate includes the amount of rainfall and the average temperature in the region. Obviously, the climate in the desert is much different than the climate in the rainforest. As a result, different types of plants and animals live in each biome. Q: The differences in the biomes is due to differences in the what factors? A:
OPTIONS:
- biological
- temperature
- air quality
- abiotic

Answer: abiotic

OPTIONS:
- metamorphic

- silicon
- peridotite
Answer: peridotite
