Answer:
water and land
Explanation:
I assume this is an open-ended question, so you could make an argument for lots of things, but these are the two most important ones in my opinion. The amount of freshwater on Earth is pretty small, only about 2.5%, and most of that is locked in ice. As the demand for food grows, the demand for water for crops and livestock also grows. This is in addition to the increase in water that is needed for a growing population. Climate change increases this problem because of drought. The second most important resource that will be affected is land. If we need more food, we also need space to grow crops and raise livestock. The available space is also reduced because people need places to live and we need to be able to grow trees for wood to build houses and other buildings. I argue that land and water will be the most in-demand commodities as the population continues to increase.
Answer:
a solution of each sodium salt at the same concentration
Explanation:
If a scientist wishes to study the electrical potential that develops between ice and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.
This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.
Answer:
D) The area was on land.
Explanation:
We can tell that this is the answer because of the process of elimination.
- It is not A or C, because there is not enough information given to us to determine whether the area was hot or cold.
- It is not B, because ferns do not grow in the ocean. (Unless it a specific type of water fern that have not heard about... but this is <u>highly unlikely</u>, so don't worry.)
- This leaves us with: D) The area was on land. This is the correct answer because ferns do grow on land, and a sedimetary rock containing a fern fossil is much more likely to be found on land than on the ocean floor.
