There are several different forms/methods of amplexus depending on the environment, body form, and relative dimorphism in the sexes. Sometimes the male will stick himself to the back of the female (called “gluing”), at another times he will straddle over the top. The drawing on the top of the next page shows the different forms.
Q24: (please type your answer) What form of amplexus did you see with the Panamanian Golden frogs?
Amplexus
Amplexus is a type of mating behaviour in externally fertilizing animals.

- Mumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face. However, the virus can also infiltrate the male reproductive system, causing the testes to atrophy. Some effects include oligospermia (low sperm count), azoospermia (no sperm in semen), and asthenospermia (reduced sperm movement). Describe how intrauterine insemination can be used to aid successful fertilization and explain why it helps. Make sure that the treatment process AND how the process helps to improve fertility are clearly explained.Which of the following statements is true? Women with endometriosis always have symptoms of the disease, even if they are only mild symptoms. Patients under 25 years of age with endometriosis are often treated with surgical hysterectomy. In endometriosis, endometrial tissue only grows on reproductive organs and cannot affect other structures in the pelvic or abdominal cavity. About 1/3 of women with endometriosis struggle with infertility.Mumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face.

- Label A-K as the following: -Seminar Vesicles -Hearts -Gizzard -Brain -Pharynx -Esophagus -Clitellum -Mouth -Septa -Seminal Receptacles -CropThere are 6 major events in fertilization. Discuss the process of fertilization or conception, with emphasis on the sperm-egg interaction. Proteins on the sperm plasma membrane bind to ZP3 molecules within the zona pellucida of the egg. Why is this event important? Zona binding triggers the acrosome reaction, in which the sperm plasma membrane fuses with the outer acrosomal membrane, causing exocytosis of acrosomal contents. What is in the "acrosomal content"? Acrosomal enzymes begin to dissolve a hole in the zona pellucida. This enzymatic degradation, accompanied by rapid sperm tail beating, moves the sperm through the zona. Where does the sperm intend to reach?Which of the following rows correctly identifies a difference between blastocysts and morula? Select one: A. Blastocyst Morula Contains trophoblast and a zygote Contains 8 cells that are totipotent B. Blastocyst Morula Contains inner cell mass with germ layers Contains 8 cells that are totipotent C. Blastocyst Morula Contains trophoblast with germ layers Contains 16 cells that can become any cells in the human body D. Blastocyst Morula Contains trophoblast and inner cell mass Contains 16 cells that can become any cells in the human body
