nadya68 [22]

Answer: Option D

A biology class is studying the effect of temperature on the amount of growth of duckweed in an aquarium. What type of data will
iragen [17]

Answer:

\boxed {\boxed {\sf They \ will \ gather \ quantitative \ data \ using \ a \  thermometer \ and \ a \ balance}}

Explanation:

First, let's identify the tools needed.

Since the biology class is studying the temperature, they will likely need a <u>thermometer</u>. Also, they are gathering information about the growth of the plants. This could use a <u>balance </u>of a meterstick.

Next, recall the difference between quantitative and qualitative data.

  • <u>Quantitative</u>: Measurable and numerical results found using scientific instruments/devices
  • <u>Qualitative</u>: Data found using the senses, such as descriptions and diagrams.

Since the class is measuring temperature and growth using tools, it must be quantitative data.

We can eliminate choices A and B, because they claim the class will gather qualitative data. Then, we can eliminate choice D, because a beaker and timer won't help with temperature and growth. That leaves choice C as the correct answer.
