Question

A student has four snails, four sprigs of Elodea, eight test tubes of brom thymol blue, and two rooms (light and dark). The student wants to know what gases are produced by the snails and Elodea in light and dark conditions. Assuming the student only has time for one experiment, what setup will yield the most complete data?

Answer 1

A: Experiment 1

Step-by-step explanation:

this is the correct answer because you have a snail in the first one. an Elodea in the second one. nothing in the third acting as the control. and finally you have both the snail and elodea in the same container. you're going to get the most results with this in both light and dark conditions.

Answer 2

setup will yield the most complete data is experiment 1
