Unit 1 SAC 2: Area of Study 2
Analyse how specific systems in plants and animals are regulated.
Introduction
In this assessment, you will demonstrate an understanding of a homeostatic control system and how it functions to maintain a stable internal environment despite fluctuating environmental conditions.Â
Students are asked to explain the biological ideas related to the purpose and mechanism of homeostatic control systems used by an athlete to maintain a stable internal environment. This involves describing how the homeostatic mechanisms incorporate the components of systems and explaining how the systems respond to a range of external conditions in a scenario related to extreme environmental conditions. To demonstrate comprehensive understanding you must link biological ideas about maintaining a stable internal environment in an athlete.
Watch the YouTube clip about the Coast to Coast race in New Zealand. Think about:
Which homeostatic control systems will be working in each of the athletes?
What are the external conditions at each stage?
How might the athletes respond to these conditions?
