One day while walking across campus, you see a female butterfly laying fertilized eggs, as shown in the image: 1. What type of ovarioles would the adult female butterfly have (hint: remember the Order of butterflies)? a. Panoistic ovarioles b. Plasmatocytic ovarioles c. Polytrophic ovarioles d. Collaterial ovarioles e. Telotrophic ovarioles 2. Which combination of mechanisms would the butterfly use to supply vitellogenins/maternal mRNAs to the developing oocytes? a. Follicular epithelial cells/trophocytes contained within the follicle b. Apical cells of germarium/nutritive cords c. Follicular epithelial cells/nucleus of the oocyte d. Prefollicular tissue in germarium/trophoocytes that remain in germarium 3. Which statement is correct with respect to the hormonal regulation of the development of the ovaries and vitellogenesis in the adult female butterfly? (Hint: the processes are the same as in a female mosquito.) a. After emerging as an adult, JH primes the fat bodies for vitellogenesis and primes the ovaries, resulting in a “resting ovary.” b. Once fully activated, the ovaries produce ecdysone, which fully activates vitellogenesis in the fat bodies. c. Vitellogenins are released into the hemolymph by the fat bodies, carried to the ovaries by lipophorins, and then taken up by the follicular epithelium under the influence of JH. d. All of these e. None of these
