Answer:
B. extraction
Explanation:
<u>In order to get oil for use, it needs to be extracted from under the ground.</u> Once the oil is located, the oil well is placed on the location. <u>The ground is drilled and the oil is popped out of the earth.</u>
While all the points in the oil handling process can be dangerous to the environment, <u>extraction has the biggest effect on the land and the sea as it can easily result in spills.</u> Oil spills affect many years later and are risky for the animals and plants. This way, the ecosystem is affected and the environment is hurt, impacting pollution and climate change.
1. Around 1900 the first dams were built on the Muskegon river, and this immediately cause a problem in the ecosystem by being a blockade for the movement of the water species, as well as causing higher mortality by killing them in the turbines.
2. By 1950 more dams were built, and the there were even more blockades on the way of the water species, so their movement was restricted even more, the mortality rates skyrocketed because of the disposing of the oxygen, temperature change, river flows changing etc.
3. Even though the scientists miss information from the period before the dams were built, since the information have started to be gathered it has been very obvious that the main factor for ruining the ecosystems on the Muskegon river are the dams by causing all sorts of changes in the water.
Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the colder air, causing an updraft. The updraft will begin to rotate if winds vary sharply in speed or direction1
All of them can be genitically modified thanks to science
Answer:
3+9 = 12
Explanation:
A <em>"counterexample" </em>is an example that shows the falseness of a statement.
Among the choices above,<em> 3+9 = 12</em> is the ideal counterexample. Its sum is an even integer (12); however, its addends are odd integers (3 and 9). So, this goes against the statement above.
The<u> first choice</u> (6+10 = 16) is clearly not a counterexample, but an example of the statement. The <u>second choic</u>e (14+9=23) is not a counterexample because its product is an odd integer, not an even integer. The statement is referring to the condition of an even integer for an answer.
