C. Read the hypotheses below, and identify the independent (what you

manipulate/change) and dependent variables (what you measure). Write

them by putting a comma in between in the space provided

12. If hatching brine shrimp is related to salinity (how salty the water is),

then the greater the salt concentration, the higher the hatching rate.

Nour answer

Independent variable: Salinity/Salt concentration

Dependent variable: hatching rate

Explanation:

As rightly stated in this question, INDEPENDENT VARIABLE, in an experiment, is the variable that the experimenter changes or manipulates in order to bring about a measurable response while the DEPENDENT VARIABLE is the variable that the experimenter measures in an experiment. Dependent variable as the name implies is dependent on the independent variable.

In this question where an hypothesis was given as follows: "Hatching brine shrimp is related to salinity (how salty the water is), then the greater the salt concentration, the higher the hatching rate". The hypothesis relates the independent and dependent variables i.e. it tells us how the independent variable affects the dependent variable.

Hence, according to the hypothesis, it is telling us how a change in SALINITY OR SALT CONCENTRATION will affect HATCHING RATE. Therefore;

Independent variable: SALINITY/SALT CONCENTRATION

Dependent variable: HATCHING RATE
