Answer:
1.) How do solar thermal generators work?
D.) They use solar cells to covert sunlight directly into electricity
2.) Fossil fuel dependence has an impact on which of the following?
A.) the environment
3.) How much money does the United States lose each year due to the non-local resource trade deficit?
D.) 300 billion
Explanation:
In solar thermal generators. they depends solely on sun's energy for its energy generation and distribution. <em>The energy generation made use of solar cells which are cells joined together in series which helps in trapping the sun's energy and converting them into electric charges for its onward transmission to the circuit and battery leading to electricity. </em>
On the other-hand, over dependence on fossil fuel causes environmental issues like global warming due to gas flaring etc.
<h2>Major: Environmental Science</h2><h2>When coal and oil are burned, they form acids that fall to the earth as rain. Acid rain can do a lot of damage, such as killing off living things in lakes. Scientists figured out, however, that lakes on limestone rock were less affected than others. Why? Limestone weakens acid. So as a short-term solution, scientists added lime to lakes where it doesn't occur naturally.</h2>
<h2>No single science was enough to come up with this solution -- it took experts in biology, chemistry, geology, and other sciences. If you major in environmental science, you'll learn to use the ideas and methods of a number of biological and physical sciences to tackle some of the world’s most pressing problems</h2>
Here is your answer:
Your answer is C decrease!
Reason: That's because when their are two predators who eat the same animal their animal species will decrease because of new predators that will eat them!
Your answer is C.
