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:

Quantitative data involves numerical measurements. A thermometer measures temperature (numerical), a balance measures mass (numerical), a beaker can measure volume (numerical), and a timer measures time (numerical). These are used to gather quantitative data related to the growth of duckweed in relation to temperature. Qualitative data is non - numerical. Tools like a meterstick and flask are not the most relevant for this study, and a hand - lens is for observing non - numerical characteristics.

Answer:

They will gather quantitative data, using a thermometer and a balance.
