In this lab, you will plan and conduct an investigation to study the response mechanism of an invertebrate to external stimuli (e.g., the instinctive behaviour of an invertebrate in response to a stimulus such as light), using appropriate laboratory equipment and techniques. You will need to:
This is a lab on simple behaviour of Teneb
Tenebrio molitor, which is the Darkling beetle. You will be working with the larval form - the mealworm. These are insects that are often used to study lifecycles and simple behaviours.
A number of the mealworms will be kept so the M4's can observe its lifecycle. It goes through a complete metamorphosis from egg to larva (it goes through several instars where it molts -sheds its exoskeleton- to allow it to grow) to pupae to adult.
The mealworms are a good source of nutrients for birds during the egg-laying season AND are an alternative protein source for humans :-)

Begin with Background Information:
identify, briefly explain then distinguish between the two types of innate behaviours: reflexes and instinctive behaviour
which of these behaviours is more important for maintaining homeostasis? Defend your choice(s)
