I am studying a species of octopus and find that some individuals have more resistance (immunity) to a common skin disease than others. I hypothesize that immunity will trades off with investments in other major life history traits. I predict that if I sample skin cells from different octopi in the wild, and assay them for immunity, females with higher immunity will produce fewer eggs. Which of the figures below would be the best choice for showing my prediction? B KA A A B

Immunology

Immunology is the division of science involved with the immune reactions occurring in living organisms. The organisms are accustomed to evolving internal defense mechanisms to evade the invasion of microbial pathogens. Diverse cells are connected with stimulating the immune responses, which produce inhospitable conditions to the microbes prompting their lysis and thus inhibits the multiplication of the pathogens. The immune system can distinguish the pathogens through the aid of cellular intercommunication and launch responses to destroy them.
