The student planned to conduct an experiment to determine how a change in the pH of water affects the population growth rate of algae.To ensure that her experimental data are valid, she should use the same species of algae in all trials.

To ensure that her experimental data is valid she should check every pH with a sample of algae. She should also write down all the data collected such as what happens when the pH changes and how much algea has grown at an specific pH. In addition, she should collect data multiple times to ensure that the replication of the experiment will result in the same data being obtained.

Genetic Engineering is on purpose.

Explanation:

Genetic engineering could range from selective breeding to adding/removing DNA and RNA. Natural reproduction occurs with the sole purpose of creating successful offspring. The offspring could he tainted if the male and female are related leaving it to not have the DNA or RNA necessary to lessen the likelihood of dysfunctional genetics.
