17
Correct Answer
A. 1Explanation
In an experiment, it is recommended to test only one variable at a time. This is because if multiple variables are tested simultaneously, it becomes difficult to determine which variable is responsible for the observed results. By testing one variable at a time, it allows for a clear understanding of the impact of that specific variable on the experiment's outcome.Rate this question:

A researcher was studying how water pollution affects fish populations in a local stream. He took samples from two areas, A and B, and these were his results. td p { margin-bottom: 0in; }p { margin-bottom: 0.08in; } Did sample have pollutants? Number of fish observed Site A Yes 3 Site B No 15 If you were the researcher, What CONCLUSION would you state about this data?
-
Pollution doesn't change how many fish there are
-
Pollution might affect the number of fish living in a stream
-
Pollution makes water dirty so fish can't breathe
Correct Answer
A. Pollution might affect the number of fish living in a streamExplanation
Based on the data collected, it can be concluded that pollution might affect the number of fish living in a stream. This conclusion is drawn because in the area with pollutants (Site A), only 3 fish were observed, whereas in the area without pollutants (Site B), 15 fish were observed. This suggests that the presence of pollutants may have a negative impact on fish populations.Rate this question:

If you wanted to know what kind of sports ball bounced the highest, what answer would be the best hypothesis to test?
-
If a soccer ball and a tennis ball are bounced, both might bounce, but they could be different
-
I think this is the wrong experiment
-
If a soccer ball and tennis ball are dropped from 3 feet up, then tennis ball will bounce higher.
-
The tennis ball will be more bouncy, but the soccer ball will go higher.
Correct Answer
A. If a soccer ball and tennis ball are dropped from 3 feet up, then tennis ball will bounce higher.Explanation
The best hypothesis to test in order to determine what kind of sports ball bounces the highest is: "If a soccer ball and tennis ball are dropped from 3 feet up, then the tennis ball will bounce higher." This hypothesis suggests conducting an experiment by dropping both balls from the same height and observing which ball bounces higher. This experiment would provide a clear comparison between the two balls and determine which one has a higher bounce.Rate this question:
