Lab 2 Quiz Bank Questions

Answer up to two questions to have reserve credit for the quizzes later in the semester. To get credit, write your answer in a paragraph IN YOUR OWN WORDS. You MUST CITE RELIABLE REFERENCES! You may add to existing comments with new information for credit, but once someone has answered (with properly cited sources), you won't get credit for repeating the information. Participation in the quiz bank questions is optional.

Please feel free to add comments & discussion to any question at any time, even if you are not answering the questions for credit. Sign your posts with your first name and last initial.

1. Why do fetal pigs have teeth? How does pig dental development (and number/type of teeth) differ from humans? (also – what about those hollow un-erupted teeth in the fetal pig? Is this what human teeth look like before they break through the gum?)

2. Do fetal pigs have an “appendix”? Why or why not?

3. What is the purpose of the soft tissue on the hooves of the fetal pig? What happens to this tissue when the pigs are born?

4. What is the stomach of the fetal pig? How does the fetal pig get food? What does the liver do in the fetal pig?

5. Pigs don’t have clavicles. Did they lose them in evolution, or did clavicles develop in other lineages of mammals? Explain the development / loss of the clavicle through evolutionary lineages.

6. Can you live without your pancreas?

7. Why are there so many large taste buds on the sides of the fetal pigs tongue?

8. How does the “morning after” pill work? Is it the same as the ‘progestin minipill’?

9. Why can some women have an orgasm and others can not? Does this have to do with the development or protrusion of the citreous? Is it true that some women can not have an orgasm at all?

10. Is there a genetic basis for homosexuality? Can homosexuality be derived from social experience?

11. Does whether or not a woman has an orgasm during intercourse affect her chances of getting pregnant?

12. How long can sperm survive inside a human body?

2. Did bones evolve from cartilage? How did bones develop?

4. Ratfish anatomy – someone please explain…

5. Brittle stars – What are their natural predators? How can they exist in such large populations without being eaten? Do they have a special type of defense?

6. What do scientists know about the adhesive of the starfish (or other animals with tube

feet that have adhesive)? Are material engineers studying this?

7. When did claws first evolve? What was their original purpose, and how has it changed with other animals?
