Homeostasis ( Year 2 - new )

Question 1

What is homeostasis?

Answer 1

The maintenance of a dynamic equilibrium within narrow ranges in the body. This is done by monitoring changes in the internal environment. For example, we keep pH, water balance of body fluids and core temp within a narrow range.

Question 2

Why do multicellular organisms need good communication systems?

Answer 2

This is because they need to coordinate the activity of organs, so a good communication system will cover the whole body and allow rapid and specific communication. It also enables short term and long term responses.

Question 3

Why is homeostasis important?

Answer 3

This ensures the right internal conditions are maintained and therefore allows enzymes to work efficiently. Enzymes are used in metabolic reactions to break down larger nutrient molecules into smaller nutrient molecules
