Worked Solution & Example Answer:An experiment was conducted to determine the effects on body function of increasing ambient temperature - HSC - SSCE Biology - Question 24 - 2009 - Paper 1
Step 1
Identify the dependent and independent variables in this experiment.
Answer
The independent variable in this experiment is the ambient temperature of the room, which is manipulated by increasing the temperature. The dependent variables are the physiological responses measured, specifically the sweating and heart rate of the participants.
Step 2
Identify the body system that monitors and responds to changes in external temperature.
Answer
The body system that monitors and responds to changes in external temperature is the thermoregulatory system, which includes components of the nervous system and skin receptors that detect temperature changes.
