As animmunologist, you are curious about how S. laker protectsitself from environmental threats.
- What are 3 different mechanisms that S. laker mightprevent microbial infection or toxinexposure during feeding? Briefly explain. Describe how you wouldexperimentally test whether S. laker uses thismechanism.
