Question

a biology class is studying the effect of temperature on the amount of growth of duckweed in an aquarium. what type of data will the class need to collect, and which tools will most likely be used? they will gather quantitative data, using a beaker and a timer. they will gather quantitative data, using a thermometer and a balance. they will gather qualitative data, using a meterstick and a flask. they will gather qualitative data, using a thermometer and a hand lens.

Explanation:

The class is studying the effect of temperature on the growth of duckweed, which is a biological experiment. Temperature is a measurable quantity (quantitative data) and can be measured using a thermometer. Growth - related measurements might involve time (using a timer) and volume/amount - related measurements which could be done with a beaker. These are tools for gathering quantitative data.

Answer:

They will gather quantitative data, using a beaker and a timer.
