Describe the feeding biology of centipedes, spiders, mites and beetles. Compare and contrast these with the sexual biology of these same animals. How might differences in feeding relate to differences in mating behavior?
Why is mating important in external fertilization of animals?
A) It ensures survival of offspring
B) It ensures sperm dilution
C) For pleasure
D) It ensures fertilization
What is one challenge posed by copulation between separate sexes? What are some adaptations that grasshoppers have developed that address these challenges?

(B) What is it about the mating system of Eusocial hymenoptera that Hamilton used to explain the evolution of Eusocial behavior in this insect group? (C) Eusocial behavior has evolved in non-hymenoptera. The explanation depends on unique features of the ecology of these organisms. What might these be? (D) Use the Florida scrub jay, sponge shrimp or naked mole rat to explain your answer.arrow_forwardHow would self-sacrifice of male redback spiders be an adaptive behaviour? Select one: a. When males meet a female and self-sacrifice, it activates enzymes that make his sperm more fit and able to fertilize more eggs. b. Males are able to mate with one female, then mate with another female nearby, before being devoured by the first female. C. Males only use self-sacrificing behaviour once they have mated with several females and have exhausted their sperm supplies. d. The chance of a male meeting more than one female is quite low; self-sacrifice maximizes mating time with and sperm transfer to any female the male finds.arrow_forward
