Question

a scientist asks, \how does the amount of salt in the water affect the number of shrimp eggs hatched?\ match each factor in the experiment below with the correct type of variable: the number of shrimp eggs that hatched the type of shrimp the amount of light the eggs are exposed to temperature of the water the amount of salt in the water the type of salt in the water :: independent variable :: control variable :: dependent variable

Explanation:

Step1: Identify dependent variable

The variable being measured, which is affected by another variable. Here, the number of hatched shrimp - eggs is what is being measured and is affected by the amount of salt. So, it is the dependent variable.

Step2: Identify independent variable

The variable that is changed or manipulated in an experiment. The amount of salt in the water is being changed to see its effect on egg - hatching, so it is the independent variable.

Step3: Identify control variables

Variables that are kept the same throughout the experiment to ensure that only the independent variable affects the dependent variable. The type of shrimp, amount of light, water temperature, and type of salt are kept constant, so they are control variables.

Answer:

The number of shrimp eggs that hatched: Dependent Variable
The type of shrimp: Control Variable
The amount of light the eggs are exposed to: Control Variable
Temperature of the water: Control Variable
The amount of salt in the water: Independent Variable
The type of salt in the water: Control Variable
