Question

question 8 (1 point) listen describe in one sentence an appropriate control for the experiment to investigate if night lights foster depression in hamsters? in this experiment, a group of hamsters is kept in chronic dim light throughout the night.

Explanation:

To determine an appropriate control for the experiment investigating if night lights foster depression in hamsters (where the experimental group is kept in chronic dim light at night), we need a group that differs only in the variable of interest (night - light exposure) while other conditions are the same.

Step 1: Identify the control group setup

The control group should be a group of hamsters that is kept in a normal, dark (or with natural - level darkness, e.g., the typical light - dark cycle without the added dim light at night) environment at night, with all other environmental and living conditions (such as food, water, cage size, temperature, etc.) being identical to the experimental group of hamsters kept in chronic dim light at night.

Step 2: Formulate the description

We can describe the control as: A group of hamsters is kept in a completely dark (or in their natural light - dark cycle without any added dim light) environment at night, with all other factors (like diet, cage conditions, temperature) being the same as the group of hamsters kept in chronic dim light throughout the night.

Answer:

A group of hamsters is kept in a completely dark (or in their natural light - dark cycle without any added dim light) environment at night, with all other factors (like diet, cage conditions, temperature) being the same as the group of hamsters kept in chronic dim light throughout the night.
