IB Bio
Henrico High School IB Biology
 
Week of June 1st


We will continue the bioethical issue debates.  After their completion, you will present a summary of your lab.

Those students will an overall C average must take the final exam.  See me for a study guide.  You have an exam schedule.

Please check K12 Planet or see me about makeup work.  All work should be made up at this time.

Bring your books in if not taking the exam.





FOR ALL IB STUDENTS STUDYING FOR TUESDAY'S PAPER 3:

Students:  Below I have given you some insight into answers as discussed in after school tutoring sessions.  Please refer to your handouts (both the one we were using and the most recent ones given to you last week) for the answers You must re-read all of these chapters
prior to tomorrow.  Also, after you have read the chapters, go to the syllabus questions with scratch paper and write the answer --- or at least key words --- to assure you know what to write.  If not, LOOK IT UP!!! It is not too late.

I give you Option D first; then A.  Please excuse poor spellings as I am doing this after school as many did not show up for the Tuesday review.

You will do well!!!!  I have such confidence in  you.  Love, Mrs Scott




Option D:   Evolution

1.1  Outline the conditions of prebiotic earth:
    
1.  high ultraviolet light levels
2.  reducing atmosphere of )2 (because there was little or no free oxygen; hence, compounds that were polymerizing were not quickly broken  (oxidized or reduced) by oxygen; hence, this promoted the formation of macromolecules
   3. gases included:  h,c, and N
4.  sources of energy:  lightning, radiation from sun, UV from sun, radioactivity from elements on earth, high temperatures due to no ozone in atmosphere


1.2 Miller and Urey’s experiment - know  the 3k inorganic compounds that were responsible for producing the first amino acids; know the electric source of energy for this

1.3 Why clay and Rna were responsible for polymerization:
1.  RNA , rather than DNA, can replicate and act as a catalyst
                        2.  Clay serves as a bond for the monomers in forming polymers
and can also catalyze certain reactions, including the formation of poly peptides from amino acids.

1.4  1.4:  RNA’s role in all of this:  has the ability of self replicating

1.5:  Origin of membranes and prokaryotic cells:

a.  membranes:  Phospholipids naturally group together to form bilayers.
The membranes form into sphere-like structures called microspheres.  They are made of droplets of fluids surrounded by membranes and can aggregate and have an identity of their own.  These microspheres are called coaservates,
                        b. prokaryote origin:  go into   endosymbiosis ( what IB likes) as well as invagination

              1.  endosymbiosis:  the chloroplast  and mitochondrion --- two prokaryotic organisms, became incorporated by endosymbiosis into another prokaryote.  Instead of being digested or killed, they remained as endosymbionts in the cell; hence, the origin of the eukaryote.  Both have their own DNA; both care capable of self-replication

1.6. Endosymbiosis - see above


2.1 Lamarck’s theory:  discuss the theory of acquired characteristics, including the example of the giraffes or the smithy's muscles; also discuss use and disuse;  why this is not plausible:  what is acquired during a lifetime cannot be passed on genetically --- must be in the genes to be passed on

2.2.  see above

2.3 Darwin-Wallace theory of evolution:  discuss the 4 principles we went over in class:

1.  there is variation in the population caused by genetic factors (crossing over, mutations,laws of inheritance, etc)
2.   Some organisms are better suited to adapt and are selected by the environment through natural selection
3.  Those selected are due to adaptations
4.  They will be able to survive and reproduce

2.4 Special creation - biblical explanation; Panspermia - microfossils of bacteria on meteorites from outer space

2.5 Evidence for theories

a.  Darwin-Wallace - the 4 evidences in the question below
b.  Panspermia - the fossils
c.  Special creation  - the Bible
d.  panspermia - meteorite fossils

3.1 Evidences of evolution - You know these:

1..  geographical
2.  anatomical (vestigial, homologous, also include analogous if you wish)
3.  embryological
4.  biochemical - the most exact
5.   fossil - discuss radioactive dating if necessary


3.2. Ways things have been preserved:  amber, ice, peat, fossils, imprints and casts, fossils

3.3. Radioactive dating:
Know this******
how it is determined:  by deducing the half-life;  the time it takes for 1/2 of the radioactive element in the sample to become stable.  PLEASE READ ABOUT THIS IN TEXT OR STUDY GUIDE REPRINT!!!!!

3.4 half-life - define

3.5 Look at  decay curve on study guides!!!!! A MUST!!!!!   p. 127 on most recent study guide; p. 276 on the one we used frequently

3.6Paleoontological evidence has to do with bones --- fossils  : You must use one example--- use the horse or Lucy

3.7 Biochemical evidence - Explain that this is the most accurate.  Can use DNA nitrogen base sequences; amino acids in proteins; etc.  Shows evolutionary relationships and ancestry

3.8 Variations in biochemicals can show phylogeny:  Again, use the evidence of amino acid sequences in a molecule such as hemoglobin.  See p. 127 of recent study guide given to you

3.9 A good example here is mitochondrial DNA and Eve

3.10  You know this.  What is the pentadactyl limb?  It is the typical limb we see when discussing anatomical similarities (homologous structures)--- see p. 126 of recent handout

3.11 Two examples of modern evolution:  you can do the peppered moth; the finches on the Galapagos

4.1 Classification of man:  memorize

4.2 Physical features of man as a primate:  grasping limbs, mobile arms and shoulder joints, opposable thumb, stereoscopic vision with forward facing eyes, upright posture with bipedalism

4.3 What does neotony mean?  That as adults we keep juvenile features.  See p. 128 of recent handout    Anatomical evidence:  remember the pictures of the pelvis and the spinal cord and the teeth

4.4  You must memorize!!!!  In the handouts

4.5 You must  memorize!!!  in the handouts

4.6 Incompleteness of the fossil record:  there are missing links due to:  bones must be deposited in an area where they will be preserved; behavior does not fossilize; animals may have eaten bones; climate and geography play a part in preserving bones

4.7 Origin of bipedalism:  Discuss Lucy (A. Afarensis) and David Johansen;  brain size --- from 300 cc to 1400 cc. 

4.8 know - rewrite tonight

4.9 know - rewrite tonight



Option A:

I am running out of time.  Things you need to know:

1.3 Constituents of a diet  -see syllabus for answers

1.4  Functions of each above  - you know this

1.5 Why a balanced diet is needed - see syllabus for answer

1.6 Know how to interpret a label

Week of May 10th    IB Biology

Students:  For the IB test, do the following:

    1.  Go over syllabus questions.  Write the answers down as if you are taking the test.  Look up what you do not know.  Leave no stone unturned.  Over the weekend, do a complete topic in the morning; then a topic at night.  You will have them done in no time!

     2.  I have placed in Virtual Share the 2003 paper 1 and 3.  Take if you have time.  Here are the answers to the multiple choice (paper 1) 2003:  d,a,b,a,a,d,b,b,c,d,c,b,c,c,a,d,c,b,b,b,c,d,d,b,b,a,c,a,d,d

2.  Remember that the major AP themes are:

     evolution
     energy transfer
     continuity and change
     structure and function relationship
     regulation
     interdependence of nature
     science and technology

The essay questions may be based on the above concepts.  For preparation, make an outline of what you would discuss if given these concepts --- include "cross topics" --- for instnace,  describe regulatory processes in a vertebrate and a plant; how does structure and function relate in two different systems.


3.  Please go to My Final Website and review the 12 AP labs.  One of the essays will be based on them.

4.PLEASE REFER TO THE FOLLOWING AS WELL for labs.  THESE ARE LOCATIONS ON APEX WHERE YOU CAN SEE EXPERIMENTS --- IF NOT IDENTICAL THEY ARE VERY SIMILAR.  PLEASE,, PLEASE,  PLEASE REVIEW THESE.
