How did the Lumber industry contribute to the pollution in Sudbury (Located in Canada)
Vika [28.1K]

As of now Sudbury has some of the cleanest air in all of Ontario. That’s hard to believe given the city once emitted 2.5 million tonnes of sulfur dioxide per year due to the Lumber industry. In the 1980s, the “Sudbury” became known as a unit of pollution, against which other industrial cities were measured. It’s now become known as a unit of restoration.

VikaD [51]
<h3>Answer:</h3>

The Correct answer is... <em>C.</em><em> Protists are a catch-all group for eukaryotes that aren't plants, fungi, or animals</em>.

<h3>Explanation:</h3>

Let's break it down!

~~~

A. Protists are all <u>heterotrophic</u>.

The given statement in answer choice A. is (partially correct) FALSE.

<em>The following statement is TRUE... The protist is classified as </em><em>either</em><em> </em><u><em>autotrophs</em></u><em> or </em><u><em>heterotrophs</em></u><em>.</em>

~~~

B. Protists can't <u>live in freshwater</u>.

The given statement in answer choice B. is also FALSE.

<em>TRUE... Nearly </em><em>all protists exist</em><em> in </em><u><em>some type of aquatic environment</em></u><em>, </em><u><em>including freshwater</em></u><em>.</em>

~~~

C. Protists are a catch-all group for <u>eukaryotes</u> that aren't <u>plants, fungi, or animals</u>.

The given statement in answer choice C. is CORRECT!

<em>TRUE... As the </em><em>catchall term</em><em> for </em><u><em>eukaryotic organisms</em></u><em> that are </em><em>not animals, plants, fungi</em><em>, or any single phylogenetically related group, it is not surprising that few characteristics are common to all protists.</em>

~~~

D. Protists are all <u>parasitic</u>.

The given statement in answer choice D. is (partially correct) FALSE.

<em>TRUE... </em><em>Many</em><em> protists are </em><u><em>pathogenic </em></u><u><em>parasites</em></u><em> that must infect other organisms to survive and propagate.</em>

<em>~~~</em>

Therefore, the correct answer choice is C.
