You are asked to explain the relationship between current and voltage. Select the statement that would be an accurate reply.
Group of answer choices
Voltage is how much current passes a point in a given time. If we want to increase the voltage, we would need to increase the current.
Voltage is the force that resists the flow of electricity; if we increase the voltage, and do not change the resistance, we will decrease the current.
Voltage is the force that drives electric current. When we increase the voltage, and do not change the resistance, we have an increase in current.
Voltage describes the amount that a material resists the flow of electrons. If we want to increase the voltage we need to increase the resistance.

Question 211 pts
Desalinization plants remove the salt from sea water and make it usable for drinking and irrigation. Review the following statements and select the one that best describes how this technology has had a positive impact on the environment.
Group of answer choices
Of all the water on Earth, 97% is salt water, 3% is fresh water and much of this is locked up in ice. All living things need fresh water to survive. As populations grow, the demand for fresh water will increase. If humans can use desalinization plants to make the fresh water they need, more fresh water will be available for the plants and animals that need it.
Some areas by the coast are very remote and far from fresh water supplies. These areas are great places to build vacation resorts. These resorts use desalinization plants to provide their guests with fresh water. Desalinization plants will allow for more resorts to be built in remote areas along the coast.
Some islands in the Caribbean do not have any fresh water. This has limited growth on these islands. Building a desalinization plant could provide jobs for the local people. This can make the economy on these islands more stable.
Desalinization plants are expensive to build and maintain; however, on some small islands, where there is no fresh water, they provide water to those who need it. Without these plants people were dependent on capturing rainwater in order to survive. In times of drought, when there was not enough rain, people used to have to buy water that was imported from other areas.
