Answer:

It is air pressure

Explanation:

"Air pressure is the weight of the atmosphere pressing down on the earth. It is measured by a barometer in units called millibars. Most barometers use mercury in a glass column, like a thermometer, to measure the change in air pressure."

I"m really sorry if this is wrong

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 thermometer. Also, they are gathering information about the growth of the plants. This could use a balance of a meterstick.

Next, recall the difference between quantitative and qualitative data.

Quantitative: Measurable and numerical results found using scientific instruments/devices
Qualitative: 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.
