CaptainCook Posted May 10, 2014 Report Share Posted May 10, 2014 So how did it go? I'm quite satisfied with paper 2, section B was great. I wasn't overly fond of paper 1 though. 1 Reply Link to post Share on other sites More sharing options...
sameera95 Posted May 10, 2014 Report Share Posted May 10, 2014 Well now we can officially discuss these exams, let's begin! how did you guys find the exams? I personally found them quite alright, and finished about 20-30 minutes early in both Reply Link to post Share on other sites More sharing options...
IBverydonesoon Posted May 10, 2014 Report Share Posted May 10, 2014 I don't remember what time zone I'm in. What were some of the questions? Reply Link to post Share on other sites More sharing options...
ibinsouthafrica Posted May 10, 2014 Author Report Share Posted May 10, 2014 In paper 2 section B, there were questions about muscle contractions, protein structure, Enzymes ( lock and key theory, and induced fit) etc.. I think paper one was okay, but I feel like there were some trick questions. In paper two the question about the pedigree chart, what did you all say about what type of inheritance it is?

I said autosomal recessive, but yeah, I was so tired and really not focused at all. Reply Link to post Share on other sites More sharing options...
sameera95 Posted May 10, 2014 Report Share Posted May 10, 2014 I don't remember what time zone I'm in. What were some of the questions?okay some of the questions on paper 2: the data analysis was about pinnipeds and their diving sessions, section b there was questions about the enzyme lock and key model, outline muscle movement, energy flow between trophic levels, control of blood sugar levels.Paper 2 (TZ2) was rather straightforward (both sections A and B), although imo paper 1 wasn't the best, seemed to focus on a good chunk of the topics but it wasn't as well rounded as some previous years in terms of the amount of topics that it covered!I don't remember what time zone I'm in. What were some of the questions?Section A focused on some reproduction/protein synthesis material and the data based talked about the use of an inhibitor in ratsthat one is time zone 1 Reply Link to post Share on other sites More sharing options...
ibinsouthafrica Posted May 10, 2014 Author Report Share Posted May 10, 2014 Yeah I said the same thing, hopefully thats what they were looking for Reply Link to post Share on other sites More sharing options...

ibinsouthafrica Posted May 10, 2014 Author Report Share Posted May 10, 2014 What about that electron micrograph, to label X, it was really hard to see... looked like it was pointing to the spaces in between. I said it was ribosomes on the RER 1 Reply Link to post Share on other sites More sharing options...
IBverydonesoon Posted May 10, 2014 Report Share Posted May 10, 2014 I really did not like the data based questions, but they were never my strength anyway soo, whatever, done with most biology! Yeah i put Nn and nn as well. I think it was autosomal as it was Nn, because if it were sex-linked it should have been written along with the X chromosome, or am I completely off? If it's not autosomal then I have probably done the entire question wrong. Also if a mother is a carrier and the dad is healthy, none of the girls should have the disease, if it is sex-linked, then they should only be carriers, so I believe that's why I wrote autosomal, but I don't really remember the question very well... 1 Reply Link to post Share on other sites More sharing options...

I said it was ribosomes on the RER i said it was the RER itself, now you're making me doubt my answer Edited May 10, 2014 by sameera95 Reply Link to post Share on other sites More sharing options...

I said it was ribosomes on the RER Haha I wrote rough ER too as it said so in the source underneath the picture, also I thought I saw some dots on it, but apparently most of the other students in my class wrote golgi, which seems to be correct. At least my teacher indicated that the golgi was the right answer, as the best student in my class chose to label it golgi. Reply Link to post Share on other sites More sharing options...

OMG i put rough ER and then put the function was to modify and package proteins for use outside the cell - that's the function of the golgi apparatus not the RER!

IBverydonesoon Posted May 10, 2014 Report Share Posted May 10, 2014 Haha Gotta love biology, I am sooo glad I'm done with the core material, what options are you guys taking? I am somewhat nervous because I don't think I did good enough in paper 1 and 2 to get the 6 I am predicted... At our school we are doing option E and H.

IBverydonesoon Posted May 10, 2014 Report Share Posted May 10, 2014 I am crossing all my legs, toes, and fingers that it in fact was rough ER, because I was so unhappy about the questions in paper 2. I absolutely hate magnification, and right before the test I was literally thinking: "Oh there's probably not going to be much questions from topic 2, so I'm not going to revise what's inside a cell or the functions of the organelles :DDD". Section B was good though. Haha Gotta love biology, I am sooo glad I'm done with the core material, what options are you guys taking? I am somewhat nervous because I don't think I did good enough in paper 1 and 2 to get the 6 I am predicted... At our school we are doing option E and H. SAME! high five! Neurobiology and Further Human Physiology (like we didn't have enough physiology to learn already) Awesome, we are going to nail that test! Yeah, I didn't like topic 6 or some of topic 11, so that we had to have option H made me a little bit sad, but now it's okay, and I just hope to get a question that I know in great enough detail!

Erasmusrasmus Posted May 10, 2014 Report Share Posted May 10, 2014 Yeah I also put it was rough ER! Cause it was like linear and had the dots on its surface and I don't think the golgi apparatus has ribosomes on the surface... 2 Reply Link to post Share on other sites More sharing options...
SeniorStatus14 Posted May 10, 2014 Report Share Posted May 10, 2014 (edited) Not quite sure if I'm TZ1 or TZ2 (What's the difference), but I feel I did alright on both. I feel like I did better on paper 1 than two though because I honestly never understood transcription/ translation even though that's what I spent the majority of time studying the past few weeks. If your last question for paper 1 was on the kidney, what answer did you put? The majority of my class and I put A, but two girls (who are top of our Bio class and act like they are right 99% of the time) said the answer was C. I think IBO graders owe our whole class at least 1 mark on paper 2 because our coordinator told us not to bring anything to the exams except water because she'd provide everything we needed and she FORGOT the rulers!! My class is so ticked off that we couldn't get that easy mark. Edited May 10, 2014 by SeniorStatus14 Reply Link to post Share on other sites More sharing options...
