Sex-peptide is the molecular basis of the sperm effect in Drosophila melanogaster. Proc Nat Acad Sci USA 100: 9929-9933 Mating elicits two major changes in the reproductive behavior of many insect females. The egg-laying rate increases and the readiness to accept males (rece... H Liu,E ...
Second, sperm transferred to a female contribute to several of her post- mating responses, such as increased egg-laying and reluctance to remate. Third, molecules transferred from male to female, either as contact pheromones or in the seminal fluid, can affect the female. In D. melanogaster, ...
The placenta is an endocrine gland that is vital to pregnancy. Learn about the structure and function of the placenta, and explore its hormones including estrogen, progesterone, and hCG. Review the corpus luteum and recognize which hormone is produced ...
Identify the hormone from the given action: Stimulates egg and sperm formation in ovaries and testes. Based on the histology of the epiphyseal (growth) plate, explain the mechanism by which bone grows in length at the epiphyseal plate during ...
- LH is responsible for triggering ovulation in females. It causes the mature follicle to release an egg. Thus, this statement is correct. Conclusion: After analyzing all the statements, we find that the incorrect statement is: -Statement i: "LH and FSH decrease gradually during the follicular...
PLD inhibitors (FIPI or 1-butanol) had no effect on the size of the hotspots, but slightly delayed their production (suggesting that PA production may play a role in sperm-egg interaction or fusion, but not the generation of the local calcium increase). The PLD inhibitors delayed and ...
