(A) It causes immediate pathogen lysis.

This statement describes the importance of this system in early pathogen defense.

<u>Explanation:</u>

Lantern fish live in the middle ocean depths where there is no sunlight. which example is a response to this dark environment? q
densk [106]

Answer:

A lighting producing organ to attract mates and prey.

Explanation:

Camouflage would do very little for a fish that spends most of it's day in the middle of a dark ocean. Mimicking other deep sea creatures would actually be more of a disadvantage than an advantage, as the sounds would be more likely to scare away potential prey, rather than attract them. A light however, would attract the prey's curiousity and urge them to check out the light.
