barriers, such as the skin and mucous membranes that prevent pathogens from entering the body, and cellular responses, such as circulating macrophages that respond to foreign invaders. Our acquired immune system mounts a specific antibody response when the body is exposed to a foreign invader, and our immune cells attack the invader Question 2.

in quickly destroying invaders (Alberts et al 2002). Melanism is a key response to insects’ innate defenses that serves many functions like improving fitness. Melanin darkens the insects’ cuticle, which is facilitated by the enzyme phenoloxidase that converts dopamine to melanin (True 2003). So when the insect is infected, host hemocytes surround around an invader and from a melanized capsule, and as the capsule darkens, cytotoxic intermediates are produced and the invader loses its ability to survive
