Big Thank you to Ms J Mergens for organizing the field trip to the Don Rix Distinguished Keynote

Genome BC welcomed our school with a sign with our school crest, gave us a personal Q and A with Dr. Budowle and regaled us with a gourmet dinner reception afterwards where we mingled with professionals in the field of forensics!  Wow.  A HUGE HEARTFELT THANK YOU TO Ms. Mergens for organizing this awesome event!!!! Our Bi 12 class is so very grateful!!

Don Rix Distinguished Lecture, photos

Apparently Sheila guessed correctly that you were all photogenic and asked if you are permitted to be photographed. Please bring ahandwritten parental note permitting photography

" We will have a photographer on site, taking photos of the talk itself and candid shots of the reception. Would be great if we could get some photos of the students. OK if I send you photo permission forms? Or was photo permission approved on the field trip permission forms that were sent out?



Thanks,



Sheila"

more questions...

number 15:  this question is about energy.  What organelle is used for energy?
mitochondria

Surface area to volume ratio:
number 58.  Remember that the cell that has the highest S.A. to Vol ratio can absorb the most nutrients
Just calculate them:
Cell A 3:1
Cell B 4:3
Cell C 3:2

If you do the calculation, then S.A /vol for Cell A is the highest at 3

Number 32 is easier if you replace the word "polypeptide" with "protein" and realize that all proteins are made by ribosome. hemogoblin, centrioles are all proteins

All lipids are made by smooth ER.
62 is an excellent organizer








Biology questions key, if there are any more questions, email me

We went over two questions in class 1.1
17:  Endomembrane system is part of the secretory process thus only secretion would be affected by a toxin.
30:  ADP is formed only when ATP is used
And ATP is used whenever energy is used
Thus only one choice uses energy. The other ones do not use energy.  Another way to ask this question is:  Which of the following processes use energy?
28.  If a channel protein or a pump stopped working, then whatever the channel might allow in would stop.  Thus amino acids would not be allowed in through the channel.

Poll results and meeting the FBI agent at the Don Rix distinguished lecture

First, your test poll.  Despite the fact that one person voted three times... this pie graph below indicates you prefer the test to be next thursday.
Next,  for those who are signed up for Oct 20,  your teachers have been given a list of your names.  They ought to give you an early dismissal at 2:45 next Tue so you can run to Nanaimo station and get to Convention Centre by, yikes, 3:30.  See if you can possibly get out prior to 2:45, in your finest, Business Casual attire.  You will be glad you dressed up a little, because Genomics BC gave us FRONT ROW SEATS so we can ask questions to the FBI agent.

Consent forms Poll for test date

Here is the consent form for the October 20 lecture. Download it.

Here's the consent form for the November 20 lecture. Download it

Here is the poll for when you want the test

Your quiz questions for next period are here and don't forget your homework is to do all the review questions for chapter 3.

Test coming up. Your review checklist. updated chapter review instructions

We are now at the end of Chapter three. We started the chapter looking at the fundamental criteria for life,  and cell organization, the definition of tissue, organ, organ system etc.

Then we took a look into the inner workings of the eukaryotic cell and its organelles.  Then we found that cells have a limit in size, due to the limitations caused by its surface area to volume ratio.   We examined Each organelle and discussed its role in the secretory process.   We briefly looked at the role of ATP generated by the mitochondria.  And we discussed how the cell transports things in and out of itself, using active and passive transport. 

YOUR STUDY CHECKLIST.  
1.  You made extensive two column notes on the fine details of chapter 3.  Use these to quiz yourself.
2.  You did your colouring in the biology colouring book: Focus on these diagrams:   The Animal Cell, The Plant Cell, Active and Passive Transport.  Know these vocab words on the diagrams.
3.  You did the Chapter Review questions at the end of Chapter 3.  DO UP TO NUMBER 62. Omit 8 and 12.  I  will look at these review questions to guide my questions for the test.
4.  You did all the labs and understand the main observations:  
a.  Lab 1  Gummi Bear lab:  Observe the effect of a hypotonic solution on Gummi Bear.  What happens to the Gummi and why.
b.  Lab 2  Sphagnum Moss lab:  Sphagnum moss is a primitive plant, a bryophyte with very thin tissue.  Observe the cell wall and vacuole under the light microscope
c.  Lab 3   Liver Anyone?   In this lab, observe the effect of the catalase enzyme from raw beef liver on a small sample of hydrogen peroxide.  Explain the function of catalase in your body.  

Lecture notes on oct9, Catalase lab


Lecture notes from Oct 7, turgor pressure, facilitated transport.


Correction: ions and amino acids use facilitated transport.  Simple diffusion is for Oxygen,  Carbon Dioxide and urea.

lecture notes on concentration gradient intro to active and passive transport
