sergiy2304 [10]

Answer:

This question is incomplete, the complete part is asking to identify the variables of the experimental statement i.e. dependent and the independent variables.

Independent variable: different amounts of time light is on

Dependent variable: Number of eggs laid by chicken

Explanation:

In a scientific experiment, variables, which are factors that can be altered, are used. These variables are independent and dependent variables.

An independent variable is that variable that is subject to manipulation or control by the experimenter in order to bring about a change in the dependent variable. For this experiment, the independent variable is the DIFFERENT AMOUNT OF TIME LIGHT IS ON.

On the other hand, a variable is said to be dependent if it is the measurable or responding variable. The response of the dependent variable is dependent on the independent variable. In this experiment, the dependent variable is the NUMBER OF EGGS LAID BY CHICKENS. The number of eggs laid (dependent variable) is dependent on the amount of time light is on (independent variable).
