Answer the following question given this paragraph: Vertebrates have a closed circulatory system with a heart. Blood is completely contained within blood vessels that carry the blood throughout the body. The heart is divided into chambers that work together to pump blood. There are between two and four chambers in the vertebrate heart. With more chambers, there is more oxygen in the blood and more vigorous pumping action. Q: Leaves respond to these environmental stimuli by producing less what? A:

OPTIONS:
- oxygen
- carbonate
- energy
- chlorophyll

Answer: chlorophyll

Problem: OPTIONS:
- malignant
- chronic headache
- tension headache
- migraine
Q: Answer the following question given this paragraph: A migraine is a more severe type of headache. It occurs when blood vessels in the head dilate, or expand. This may be triggered by certain foods, bright lights, weather changes, or other factors. People with migraines may also have nausea or other symptoms. Fortunately, migraines can often be relieved with prescription drugs. Q: When blood vessels in the head dilate, what kind of severe headache can occur? A:
Answer: migraine

Problem:OPTIONS:
- hidden potential
- change potential
- false potential
- action potential

Answer the following question given this paragraph: Q: Temporal and spatial summation at the axon hillock determines whether a neuron generates what? A:
****
A: action potential

Answer the following question given this paragraph: Some solutes, such as sodium acetate, do not recrystallize easily. Suppose an exactly saturated solution of sodium acetate is prepared at 50C. As it cools back to room temperature, no crystals appear in the solution, even though the solubility of sodium acetate is lower at room temperature. A supersaturated solution is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature. The recrystallization of the excess dissolved solute in a supersaturated solution can be initiated by the addition of a tiny crystal of solute, called a seed crystal. The seed crystal provides a nucleation site on which the excess dissolved crystals can begin to grow. Recrystallization from a supersaturated solution is typically very fast. Q: What is used to recrystallize excess dissolved solute in a supersaturated solution? A:
OPTIONS:
- starter crystal
- energy crystal
- fertilizer crystal
- seed crystal
seed crystal
