Tessa knows that the sea grape tree can grow well in areas of high st and poor soil. She has seen sea grape growing along the beach strands and coastal hammocks of south Florida. She sets up an experiment to see which amount of salt is best for sea grape. She chooses two plants. She gives pure water to the first plant and a strong salt water solution could Tessa do to improve her experiment? the econd. Then, she measures growth.

The answer of this question is B. Tessa could use more plants and multiple trials

Explanation: In Tessa’s experiment, she has two sea grape plants and gives one pure water and the other a strong salt water solution. Tessa is trying to determine which amount of salt is the BEST for sea grape. With the experiment she set up however, she isn’t going to be able to determine which amount of salt is the BEST for the sea grape because she is only giving one sea grape plant salt. If Tessa were to have more sea grape plants and gave them all different amounts of salt, she could determine which amount of salt is best for the sea grape.

Hope this helped! If you have any questions about my answer feel free to comment on the question.
