AP Biology (Period 3) Assignments

Read artificial selection lab handout and be prepared to set up the lab as a class.

Chapter 9 notes will be due on Wednesday so you may want to get started on them as well.

Read the Hardy-Weinberg lab and be prepared to start work on the computers on Tuesday.

I have ordered another AP Biology review book (Kaplan) and this one sounds like it will be useful for students. I hope to have it by Monday so I can bring it to class to show you. It was just released and the few teachers who have looked at it say that it is the first decent review book. There is another new review book (Barrons's) that is to be released on 2/1/2013. I will give you more information after it becomes available to examine.

DO NOT BUY THE PRINCETON REVIEW BOOK! It has NOT been updated for this new exam.

Notes on chapter 15-1,2,3.

HARDY-WEINBERG PROBLEMS:
1. A farmer bought a herd of 600 sheep, taken from a freely breeding population, and later found that 150 of the animals had an economically undesirable feature, crinkly-hair, caused by the recessive allele cr.
a. What is the frequency of this undesirable allele in the herd?
b. What proportion of the herd is likely to be heterozygous?
c. The owner then separates all those animals showing crinkly-hair and sends then for slaughter. He allows the remaining animals to breed freely. What proportion of the next generation of lambs would be expected to show crinkly-hair?
2. The alleles for red and white coat color in cattle show absence of dominance, the heterozygous being the color road.
a. In a freely breeding herd of 1000 head, how many would you expect to be of each coat color if the allele for white coat has a frequency of 0.4?
b. If all the white cattle were sold for slaughter and the red and roan animals were allowed to breed freely, about what percentage of the offspring would be expected to be white?
3. A different rancher decided to raise these cattle in an isolated valley and bought 1000 head, which he transported to the valley to establish a randomly mating population. When released, the animals consisted of 130 white-coated cows, 330 red, and 540 roan.
a. Does this represent a population in equilibrium?
b. What will be the proportions of coat color in the next generation?
4. If the frequency of one allele at a locus with two alleles is 0.73, the frequency of the other allele must be ______________________.
5. Suppose there are two alleles at the Duffy locus in a chimpanzee population: h1 and h2. If 95 individuals are homozygous for h1, 70 are heterozygous, and 35 are homozygous for h2, the allele frequency of h1 is ______________________.
6. Suppose that in a population of 1400, one finds 125 individuals homozygous for allele A7 and 350 heterozygous for the allele. The frequency of the A7 allele is ¬¬¬¬¬¬¬¬¬_____.
7. Under Hardy-Weinberg equilibrium, if the frequency of one allele is 0.7 and the frequency of the other allele is 0.3, then __________ of the population should be heterozygous.
8. In a population of two alleles at a locus that is at Hardy-Weinberg equilibrium, the maximum proportion of heterozygotes possible in a population is _____. This maximum point will be reached when the frequency of one allele is _____ and the other allele has a frequency of _____.

Complete the pedigree worksheet I gave you in class.

Data from class in another State - for chi square analysis for mitosis lab:


Interphase Mitosis
Control 460 75
Lectin 417 209
caffeine 549 26


YOUR CLASS DATA:

CONTROL 271 549
CAFFEINE 282 246


Entire lab - including chi square analysis is due the day you return from vacation on 1/7/2013. Answer ALL questions, include all data and statistical analysis, in your lab books.

NOTES ON CHAPTER 8 ARE ALSO DUE ON 1/7/2013.

http://www.youtube.com/watch?v=pOROHmEmqmU&list=PL0B4CED0AB112B993&index=5

This video reviews the mitosis and meiosis labs you are writing up. Remember that they are due on 1/7/13.


Here is the updated data you collected as a class. Please compare this class data (by chi square analysis) to the data I posted from a class in another state and to the data YOU collected from the prepared slides and index cards. Using only the data from the other class, please compare the control and experimental cells in mitosis (again by chi square analysis).

(see attached file)

For the meiosis portion, using the data you collected from the Sordaria cards, calculate the percent crossing over and the map unit distance between the genes.

Due to questions I have received from a few students, I will try to clarify the lab assgnment:

Okay. I see what happened. My formatting was lost when I saved the data to the site (I tried again, and still no luck). THIS is the data from the other AP class in another State:

Data from class in another State - for chi square analysis for mitosis lab:

xxxxxxxx number of cells in:
Treatment Interphase Mitosis
Control 460 75
Lectin 417 209
caffeine 549 26


Use THIS data to see if Lectin and/or caffeine affected the % of cells in mitosis. You should also compare these numbers for the control population with the numbers YOUR CLASS found on the slides you made (use the updated class control data from the previously attached file), numbers found on the pre-prepared slides, and numbers of cells in mitosis found on the cards to see it they are consistant with each other (ie. do a chi square analysis for each pair). Finally, compare the numbers of cells in mitosis in the control and lectin or caffeine from the slides prepared by YOUR CLASS.

Be sure to include explanations of what was happening and why it happened.

Finish your notes on chapter 7 if you have not done so already.

Read the ENTIRE mitosis/meiosis Lab packet and answer ALL Pre-Lab questions in your lab book. This is due on Monday. First we will model the processes with pipe cleaners. I hope to start the slide portion on Tuesday. I will be preparing the onion roots with the HCl and fixative for you. You will be staining the root tips, making the squashes, and counting cells.

Your lab write-up will be due 1/7/13.

make sure you review the chapter in your books on the immune system

Please read chapter 31 on Immunology this weekend.
Remember to bring headphones to the Tech Center on Monday.

I just received this invitation to a competition that some of you might like to attend:

I am writing to cordially invite your students to compete in the annual Los Angeles Brain Bee, a neuroscience competition for high school students. The LA Brain Bee will be held at the Zilkha Neurogenetic Institute at the University of Southern California on January 26th, 2013. The event aims to stimulate interest in neuroscience education and research in all communities. STUDENTS DO NOT NEED A COACH OR SPONSOR. Students simply prepare for the Brain Bee by studying a free downloadable book provided by the Society for Neuroscience. Prizes will be awarded to the top 3 competitors, and the winner of the Brain Bee will get a trophy, a monetary stipend, and a trip to compete in the National Brain Bee (March, Washington D.C.). In LA, we invite students, parents, teachers, and everyone to a full day’s program. In addition to the competition, there will be laboratory tours at USC, a student-guided panel session on college life and the sciences, posters, games, and a talk from a distinguished speaker. For complete details and more information on the Los Angeles Brain Bee, please go to: http://www.losangelesbrainbee.com.

Next chapter test is November 19 and 20. It covers organelles, membranes, diffusion, cell signaling, etc. It is mostly chapters 4 and 5, with touches of chapters 26 and 29 and of course, the labs. Make sure that you keep up!

On Friday, we will finish the presentations and you will have time to examine the posters in more detail and/or go over the chapter 4/5 packets with your classmates.

Be sure to bring the packets to class!

The test on membranes, organelles, membrane transport, and cell signaling is on MOnday and Tuesday.

The cell signaling poster is due on 11/13. Be prepared to present your 5-7 minute talk explaining your topic on this day. Obviously, some groups will present the next day as well, but you need to be prepared.

Your poster should be simple poster board - the kind that comes 10 sheets in a package for $4-5. You can get together with classmates and split the cost of a package. See me if this is financially a problem.

Make sure that you are spending some time watching the youtube videos I posted earlier. they should be helpful.

As requested, I have changed the due date of the cell size lab until Thursday.

The cell size lab is due November 8. Please write up the lab in your lab books (individually). This is a less formal lab; you will need to have an introduction, materials, procedure, a hypothesis only for the first part (which is a comparison of 2 different sizes of cubes). For part 2, explain why you chose that size and shape and answer the questions on the handout.

We will start working on the math of water potential and discuss the lab on Thursday, so make sure that you have read through the entire packet you received today.

As promised, here are several videos that discuss osmosis, diffusion, and water potential.

Lab mini-posters due on Wednesday.

The cell size lab will be due next week, November 7. Please write up the lab in your lab books (individually). This is a less formal lab; you will need to have an introduction, materials, procedure, a hypothesis only for the first part (which is a comparison of 2 different sizes of cubes). For part 2, explain why you chose that size and shape and answer the questions on the handout.

The FRQ portion of your test is on Friday. Be prepared!

The enzyme lab poster will be due on Wednesday. Work with your group between now and then. You may pick up the folders for the mini-posters from me tomorrow or Monday.

Monday, we will begin our study of cells, membranes, and communication between cells. We will cover primarily chapters 4 and 5 in POL. You should also review chapter 11 in Campbell. Your next test will be November 19 and 20 - just before the Thanksgiving vacation.

Take a look at the following site. It discusses induced fit of enzymes.

http://web.chem.ucsb.edu/~molvisual/ABLE/induced_fit/index.html

Also, I have attached the file for the catalase lab. Be prepared to get to work on this as soon as you get to class on Tuesday. Please note that there may be a few changes in this version and the one you received in class.

I saw many instances of students contaminating reagents today. FOLLOW DIRECTIONS! Think about what you are doing before you act. Be careful or the experiment will not work for anyone.

Please read the Toothpickase lab I have attached to this homework before class on Friday.

Finish up the Origins of Life lab - both the guided inquiry and the full inquiry portions before Monday.

Review enzymes!

Please try to hand in your Origins of Life lab (both the guided inquiry and the open inquiry parts) on Thursday.

If you have a pair of heavy winter gloves, please bring them to class on Friday.

Notes for chapters 2 and 3 are due on Wednesday.

READ THE FRUIT FLY BEHAVIOR LAB AND BE READY TO START WORK ON IT ON MONDAY.

Bring lab books, new textbooks, your Appendix B packets and your questions to class on Monday.

You will work with your partner to compute a chi square analysis of your Brine shrimp data, go over the Appendix B questions with your lab bench partners, and begin work on the chapter 1/18 packet that you will receive in class.

Remember that your chapter 1 notes (NEW book) are due on Tuesday, your lab report is due on Thursday, and your first Ecology test is on Friday. The Ecology test will cover the chapters you took notes on this summer which correspond to chapter 42, and parts of 44 and 46 in the new book.

Answer the questions that go with the Appendix B handout you received in class. Try to do some each day. If necessary, I will extend the time, but I would rather not do so. You will be tested on graphing!

Short test on Statistics and graphing! Be prepared with a four function calculator - NOT a graphing calculator or a scientific calculator.

Read about Brine Shrimp lab and begin your lab report in your lab book. Decide with your partner which experimental condition you will use and bring any needed materials to school on Monday. I will have the basics, plus extra salt, pH paper, HCl and NaOH. I have empty cabinets available or you can bring aluminum foil if you want to use amount of light as an experimental condition. I will have limited internet access this weekend, but you may send questions if you wish and I will do my best to answer them when I can.

Complete the Chi-Squared worksheet in the packet I gave you today. Read the left-hand side of the page first.

You may want to watch the following youtube video:
