Which of the following is not true about neurulation? Choose all possible answers. a. Segregation of neural ectodermal rudiment from the epidermal ectoderm. b. In primary neurulation, the neural plate thickens along its midline into a solid cord of cells that is displaced internally and cavitates to form a hollow tube. c.

How do you expect Kartagener syndrome leads to infertility? A. The lack of a plasma membrane means that pathogens and foreign substances can permeate the sperm and damage the DNA B. The lack of microtubules mean the sperm do not have tails and cannot swim to fertilize the egg C. The lack of dynein means that the sperm cannot bend their tails to swim and fertilize the egg

In a possible future scenario, male fertility drops to zero, but, luckily, scientists develop a way for women to pro-duce babies by virgin birth. Meiocytes are converted di-rectly (without undergoing meiosis) into zygotes, which implant in the usual way. What would be the short- andlong-term effects in such a society?

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.…
