Answer the following question given this paragraph: The echinoderm nervous system has a nerve ring at the center and five radial nerves extending outward along the arms. There is no centralized nervous control. Echinoderms have separate sexes and release their gametes into the water where fertilization takes place. Echinoderms may also reproduce asexually through regeneration from body parts. Q: What process takes place when echinoderms release their gametes into the water? A:
OPTIONS:
- migration
- stimulation
- isolation
- fertilization
fertilization

Answer the following question given this paragraph: Ocean water also absorbs gases from the atmosphere. The most important are oxygen and carbon dioxide. Oxygen is needed by living things in the oceans. Much of the carbon dioxide sinks to the bottom of the seas. Carbon dioxide is a major cause of global warming. By absorbing carbon dioxide, the oceans help control global warming. At least as long as the carbon dioxide stays in the seas. Q: Oceans help control global warming by absorbing what? A:
OPTIONS:
- hydrogen
- ozone
- methane
- carbon dioxide

Answer: carbon dioxide

Question: Answer the following question given this paragraph: Potassium Potassium is the major intracellular cation. It helps establish the resting membrane potential in neurons and muscle fibers after membrane depolarization and action potentials. In contrast to sodium, potassium has very little effect on osmotic. Q: What is the major intracellular cation? A:
OPTIONS:
- magnesium
- sodium
- glucose
- potassium
Answer: potassium

input with options: Answer the following question given this paragraph: The rate at which a device changes electric current to another form of energy is called electric power . The SI unit for powerincluding electric poweris the watt. A watt equals 1 joule of energy per second. High wattages are often expressed in kilowatts, where 1 kilowatt equals 1000 watts. The power of an electric device, such as a hair dryer, can be calculated if you know the voltage of the circuit and how much current the device receives. The following equation is used:. Q: What unit of power is equal to 1 joule of energy per second? A:
OPTIONS:
- hertz
- byte
- volt
- watt
output: watt

Q: Answer the following question given this paragraph: Water is an example of a common chemical compound. As you can see in the Figure below , each water molecule consists of two atoms of hydrogen and one atom of oxygen. Water always has this 2:1 ratio of hydrogen to oxygen. Like water, all compounds consist of a fixed ratio of elements. It doesn't matter how much or how little of a compound there is. It always has the same composition. Q: What molecule consists of two atoms of hydrogen and one atom of oxygen? A:

OPTIONS:
- carbon monoxide
- hydrogen peroxide
- air
- water

A: water

Answer the following question given this paragraph: Bombarding a target of one element with high-energy nuclei or subatomic particles can create new elements. Electrostatic repulsions normally prevent a positively charged particle from colliding and reacting with a positively charged nucleus. If the positively charged particle is moving at a very high speed, however, its kinetic energy may be great enough to overcome the electrostatic repulsions, and it may collide with the target nucleus. Such collisions can result in a nuclear transmutation reaction. Q: What normally prevent a positively charged particle from colliding and reacting with a positively charged nucleus, but may be overcome by kinetic energy?. A:
OPTIONS:
- kinetic repulsions
- toxic repulsion
- evaporation repulsions
- electrostatic repulsions
electrostatic repulsions
