Q: Answer the following question given this paragraph: Millions of fossils have been found since Darwin's time. They show that evolution may occur in fits and starts. Long period of little or gradual change may be interrupted by bursts of rapid change. The rate of evolution is influenced by how the environment is changing. Today, Earth's climate is changing rapidly. How do you think this might affect the rate of evolution?. Q: Fossil records show that what process may occur in "fits and starts"? A:

OPTIONS:
- generation
- isolation
- variation
- evolution

A: evolution

input: OPTIONS:
- glucose
- carbon dioxide
- oxygen
- glycogen Now, answer this question: Answer the following question given this paragraph: Glycogen is an even more highly branched polysaccharide of glucose monomers that serves a function of energy storage in animals. Glycogen is made and stored primarily in the cells of the liver and muscles. Q: What is made and stored primarily in the cells of the liver and muscles? A:
A:
output: glycogen

Answer the following question given this paragraph: A fleshy bead of tissue called the uvula drops down from the center of the posterior edge of the soft palate. Although some have suggested that the uvula is a vestigial organ, it serves an important purpose. When you swallow, the soft palate and uvula move upward, helping to keep foods and liquid from entering the nasal cavity. Unfortunately, it can also contribute to the sound produced by snoring. Two muscular folds extend downward from the soft palate, on either side of the uvula. Toward the front, the palatoglossal arch lies next to the base of the tongue; behind it, the palatopharyngeal arch forms the superior and lateral margins of the fauces. Between these two arches are the palatine tonsils, clusters of lymphoid tissue that protect the pharynx. The lingual tonsils are located at the base of the tongue. Q: Although some have suggested that the uvula is what type of organ, it actually serves an important purpose? A:

OPTIONS:
- essential
- parietal
- remnant
- vestigial

Answer: vestigial

Problem: OPTIONS:
- oceanic alps
- blue ridge mountains
- sea mounds
- mid-ocean ridges
Q: Answer the following question given this paragraph: mid-ocean ridges : A long chain of mountains that rises up high above the deep seafloor. An example is the light blue gash in middle of Atlantic Ocean. Light blue is higher elevation than dark blue. Q: A long chain of mountains that rises up high above the deep seafloor is called? A:
Answer: mid-ocean ridges

Problem:OPTIONS:
- fluid
- crystal
- ice
- gas

Answer the following question given this paragraph: Depending on the surrounding conditions, normal matter usually exists as one of three phases: solid, liquid, or gas. A phase change is a physical process in which a substance goes from one phase to another. Usually the change occurs when adding or removing heat at a particular temperature, known as the melting point or the boiling point of the substance. The melting point is the temperature at which the substance goes from a solid to a liquid (or from a liquid to a solid). The boiling point is the temperature at which a substance goes from a liquid to a gas (or from a gas to a liquid). The nature of the phase change depends on the direction of the heat transfer. Heat going into a substance changes it from a solid to a liquid or a liquid to a gas. Removing heat from a substance changes a gas to a liquid or a liquid to a solid. Two key points are worth emphasizing. First, at a substance's melting point or boiling point, two phases can exist simultaneously. Take water (H2O) as an example.

Problem:OPTIONS:
- abducent nerve
- trochlear nerve
- oculomotor nerve
- optic nerve

Answer the following question given this paragraph: When light hits rods and cones, it causes chemical changes. The chemical changes start nerve impulses. The nerve impulses travel to the brain through the optic nerve . Q: Through what does the nerve impulses travel to the brain? A:
****
A:
optic nerve
