Biology Theory Revision Questions

Hey guys!  Threw together some creatively-titled questions targeted at knowledge revision as we head towards exams.  It's all too easy to fall into the trap of spamming a heap of practice exams without checking that you've actually learnt and understood all your theory.  To score well, you need to know (or be able to make up ;)) most of this basic information, as it forms the basis for theory and application questions on the exam.

To put it more clearly: if you do 50 trials but never learn to write out the process of transcription and translation...

... then you're a stupid idiot.  Three easy marks down the drain.

So, these are just deceptively simple questions straight from the study design.  Simple, because they're not application or deduction questions, rather they simply check your knowledge, hopefully at VCAA's level.  But deceptively so, because they test a year's worth of information, and one simple question can hold a whole chapter!  Let me know if you think there's anything I should add or change.

I'd recommend tackling one spoiler tag per night (or every second night), closed-book since they're purely knowledge tests to check what you need to relearn.  Solutions?  Why, that's half the fun.  That's up to you, your notes, and our close mutual friend Mr. Google ;D  Please write full open-book solutions afterwards and relearn what you'd missed, or there won't be much point in this exercise!  These questions are infinitely repeatable.

^ I'm delighted you found these useful!

Just to let you know that I've added 2/3 of Unit 3 AOS 2, and all of U4 AOS 1 :D  Please let me know if you have any suggestions for improvement, I'll take them seriously no matter how small!

The first question of lipids was a bit unclear

Yeah - there are many types of lipids with some different subunits.  I was thinking fatty acids + glycerol, based on VCAA exams.  Is there a way to make the question clearer?  Thanks for the feedback, always much appreciated :))

I was thinking fatty acids and glycerol but steroids aren't like that. Maybe it could be split up into the sub units of specific types of lipids?

Have updated it so that it's finished :)  Apologies for poorly expressed or strange questions in some sections; hopefully I'll gradually improve them over time, especially if I get feedback.

This is actually really comprehensive! Better than any textbook questions. Great job!

Since these questions are still relevant to this year's study design, might be worth a look as a great way of studying as exams start approaching!

Good luck :D

Thank you for the questions. I am a current year 12 student and the bio study design has changed since 2015, would you still recommend doing these questions.

Thank you for the questions. I am a current year 12 student and the bio study design has changed since 2015, would you still recommend doing these questions.
Most of the questions are still relevant.
From a quick glance, the questions that aren't relevant are:
 - The cell cycle
 - meiosis
 - the 2nd and 3rd question on chromosomes
 - questions 2-8 from genotypes and phenotypes
 - punnet squares
 - dihybrid crosses

So avoid those above questions. I may have missed some, so if you intend on doing the questions, you should have the study design up and check to see if any content is not within the current course.

Note that (I believe) the new study design brought in some extra detail to immunology and some new elements to evolution (although i'm not sure) so these questions may be lacking in those departments as well.

Hopefully, this helps and good luck with bio this year!
