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:
****
A: soluble

Answer the following question given this paragraph: All plants are adapted to live on land. Or are they? All living plants today have terrestrial ancestors, but some plants now live in the water. They have had to evolve new adaptations for their watery habitat. Q: Where do all plants come from? A:
OPTIONS:
- phylogenetic ancestors
- distant ancestors
- cetacean ancestors
- terrestrial ancestors
terrestrial ancestors

Answer the following question given this paragraph: Matter can be classified on the basis of how light interacts with it. Matter may be transparent, translucent, or opaque.

Answer: light

Question: Answer the following question given this paragraph: Isotopes with magic numbers of protons and/or neutrons tend to be especially stable. Elements with magic numbers of protons tend to have more stable isotopes than elements that do not. Q: Elements with magic numbers of what tend to have more stable isotopes? A:
OPTIONS:
- nucleus

- protons
Answer: protons

input with options: Answer the following question given this paragraph: Hearing is the ability to sense sound waves, and the ear is the organ that senses sound. Sound waves enter the auditory canal and travel to the eardrum (see Figure below ). They strike the eardrum and make it vibrate. The vibrations then travel through several other structures inside the ear and reach the cochlea. The cochlea is a coiled tube filled with liquid. The liquid moves in response to the vibrations, causing tiny hair cells lining the cochlea to bend. In response, the hair cells send nerve impulses to the auditory nerve , which carries the impulses to the brain. The brain interprets the impulses and "tells" us what we are hearing. Q: What is the organ that senses sound? A:
OPTIONS:
- nose
- eye
- skin
- ear
output: ear

Problem: OPTIONS:
- instantaneous
- fluctuations
- planned
- spontaneous
Q: Answer the following question given this paragraph: Chemists want to be able to predict the outcome of reactions. They would like it to be possible to predict what will happen when reactants are added together under a given set of conditions. The conditions of a reaction might include things like temperature, pressure, and concentrations of various reaction components. If the given conditions favor the formation of products, the reaction is said to be spontaneous . Q: How is a reaction described when the given conditions favor formation of products? A:
Answer:
spontaneous
