SCORE:
This assignment is worth 30 points.
Using your textbook and/or reliable Internet references, answer the following questions.
You may wish to review several websites or sources to verify your answers.
Submission Directions
Type out (do not handwrite) your answers to the questions below within this MS Word
document by typing your answers between the questions listed below. BE SURE TO TYPE
OUT YOUR NAME ABOVE. Print out your completed assignment WITH YOUR NAME ON IT
and submit it in printed form to Blake in lab or to Blake’s Box in EBS 212 (the Biology Office)
NO LATER THAN 5 pm on the due date indicated on the ASSIGNMENTS page of the course
website. Multiple students MAY NOT submit the exact same answers for credit – do your
own work and write your answers in your own words.
DO NOT CUT AND PASTE FROM WEBSITES OR DOCUMENTS ON THE INTERNET.
BE SURE TO ANSWER ALL OF THE PARTS FOR EACH NUMBERED QUESTION.
1. The National Park Service (NPS) and the Nature Conservancy have removed the feral
pigs from Santa Cruz Island and other islands in the Channel Islands off of Santa
Barbara. The feral pigs are invasive non-native species. This will help increase the
survival of the largest mammal on the islands. What mammal is this? What specific
mammal and what bird species’ are involved and briefly describe the food web involved.
Note the answer involves the mammal, two different eagle species and a pesticide.
2. What is Bernoulli’s Principle? Describe how Bernoulli’s Principle relates to bird flight.
3. Relative to primate locomotion, what is brachiation? List three different primate species
that demonstrate brachiation. What is the evolutionary advantage of this type of
locomotion in these species?
4. How does the structure of a chimpanzee pelvis differ from the structure of a human
pelvis? What is “knuckle-walking”? Give an example of a primate that is a “knucklewalker”? Why must this animal walk using this posture? List three ways to distinguish
between a human male and human female pelvis.
5. What is Boyle’s law? How does Boyle’s law related to the function of the respiratory
system in mammals?
6. What is a prosimian? Give two different examples of prosimians. How are prosimians
different from apes and monkeys?
7. What is a nephron? In what vertebrate organ are nephrons found? Draw a simple
diagram of a nephron and clearly label each of the parts. Generally, what types of
molecules and in which direction (from blood to tubules or tubules to blood) do
molecules move during each of the three processes involved in urine formation:
 glomerular filtration
 tubular reabsorption
 tubular secretion?

8. How does an erythrocyte carry oxygen? What specific molecule and ion is involved?
How is most of the carbon dioxide in the blood transported? What important enzyme is
involved? How does the enzyme that helps transport carbon dioxide in the blood also
function in the stomach (what does this enzyme do in the gastric pits)?
9. What is the oxygen level of the blood transported by the umbilical arteries versus
umbilical veins (oxy or deoxy)? List two different structures in the mammalian fetal
heart that shunt blood away from the fetal lungs and to the placenta.
10. What is a therapsid? To what class of vertebrates did this group evolve? What is the
evidence for this evolution?
11. Why do some animals migrate? List three different animals in three different classes
and briefly describe their migration. List at least two different explanations of how
these animals navigate during their migration; note these need not necessarily be
vertebrate species.
12. Relative to mammals, what is a home range? Which has a larger home range, a larger
or a smaller mammal and why?

the timing of the following events together as they occur during the menstrual
FSH has dominant effects on the ovary
LH has dominant effects on the ovary
increased estrogen production
increased progesterone production
follicular phase of ovary & proliferative phase of uterus versus,
secretory phase of uterus & luteal phase of the ovary
increased basal body temperature
copious, watery cervical mucous versus thick, viscous cervical mucous
during the menstrual cycle, when do the menses and when does ovulation each
occur (around what days of the menstrual cycle)?
