Question

The amount of chlorophyll in a leaf changes based on outside temperature. What's the independent variable in the situation?

Answer 1

Answer:

Step-by-step explanation:

Given that the amount of chlorophyll in a leaf changes based on outside temperature. Here there are two variables.

i) Amount of chlorophyll in a leaf

ii) outside temperature

Here outside temperature is an independent variable as amount of chlorophyll in a leaf cannot control it.

But on the other hand, Amount of chlorophyll in a leaf depends on the outside temperature and hence cannot be independent but dependent variable

Recall the definition of dependent and independent variable

An independent variable is the variable that is controlled in a scientific experiment to test the effects on the dependent variable.

A dependent variable is the variable being tested and measured in a scientific experiment.
