A local citizen science group is monitoring the water quality of a nearby lake. They gather water samples once a week on Wednesday between the hours of 7 A.M. and 9 A.M. from the same location. One day in August they were unable to sample within that time frame and collected the sample at 3 P.M. How might this difference in sample collection time affect the results?

• Water sampled later in the day may be warmer and therefore have lower dissolved oxygen levels.

• Water sampled later in the day may have increased insect respiration and therefore higher dissolved oxygen levels.

• There would be no difference
