This quiz reviews key concepts in Goal 5
- 1.
Alexander compares three water samples. The volume of each sample is 200mL. He measured the temp of each sample and recorded it. Which water sample contains the highest level of Dissolved oxygen (DO)? Water Sample 1: Temp 68 degrees F, source kitchen sink Water sample 2: Temp 35 degrees F, source frozen puddle that just thawed Water sample 3: 50 degrees F, source a stream that sits in the Sun
- A.
Sample 1
- B.
Sample 2
- C.
Sample 3
- D.
Temp does not affect oxygen levels
Correct Answer
B. Sample 2Explanation
Because sample 1 came from a sink, there are no organisms there to contribute to the DO level. Sample three is going to have a lower DO because it is in the direct sunlight. Sample 2 is the best answer.Rate this question:
