Hi guys!

I was wondering if in your opinion question 19 in MC of 2015 exam seems relevant to current study design? I think not but since I didnít do bio 1/2 I have no idea what anaphase and prophase is, so I could be wrong!

Thanks very much 😊

I just looked at Q19 on 2015 exam and it's about autoimmune diseases and would be relevent. Have you got the right year/question number?
Mitosis/meiosis and the prophase/anaphase stuff is definitely not needed for year 12 bio though!

I suspect you meant the 2016 exam, and yes MC Q16 2016 exam is not examinable in 3/4 bio

Hey, I had a question about the specific wording when it came to defining pandemic. My teacher said the best word to use was wide spread but another person said to say uncontrolled spread not wide spread. Will it be wrong to use both of their advice and wrutr uncontrolled wide spread infection or will this also be wrong?
Thanks!

I dont't see any issue with either terms you could easily say "uncontrolled and widespread" personally I would use widespread, since pandemics cross borders and reaches multiple continents. Hope that helps

Hey everyone,

Does anyone have any other Unit 3/4 Biology exams other than VCAA? My school has not given us any extra practice so I would appreciate it if you guys could post some more exams for me please!

Thank you  ;D

Sorry, we can't really have users posting copyrighted material on these forums.

There are some free practice exams which you can find HERE

It might be useful to ask your teacher or other students whether they have any other exams.

Just adding onto what tiredandstressed has said,
the study design states you need to know the difference between an epidemic and pandemic, and so i think you definitions should reflect this difference. I would define them as 'a pandemic is a widespread disease across multiple regions' whereas a epidemic is 'a disease effecting people within a region'. I don't think widespread or uncontrolled are important key terms here - its more the distinction between within region or across multiple regions.

Is the water produced in aerobic respiration used in photosynthesis or is it simply released as a by-product out of the plant?

Aerobic respiration occurs in the mitochondria, hence this is the site where water is produced (specifically at the end of the ETC on the cristae when oxygen accepts hydrogen ions and electrons). This water produced here then simply joins the rest of the cells's water as part of the cytosol. This water has no specific destination - some of it will eventually leave the plant (i.e. via transpiration), some of it will participate in other reactions (i.e. photosynthesis) and some of it will remain in the cytosol.
It can be confusing sometimes when people say the outputs of cellular respiration are (mostly) the inputs of photosynthesis, but this statement is not so much referring to the specific molecules of water produced, but rather the substance more generally.
Hopefully this clears up the confusion :)

For this question would this be a sufficient answer
Describe how the fossil record supports the theory of evolution.

The fossil record supports the theory of evolution as it indicates how life has changed over time and shows the evolution of eukaryotic cells from prokaryotic cells. The fossil record provides evidence of the extinction of species

Hey Chocolatepistachio! :D
This is a fantastic start ;D
I have provided an edited response below.

If this question has a stimulus, always refer to it because on some marking criteria it may say, "refers to stimulus", meaning that it should be part of your response. I don't know if this question had a stimulus or how many marks this question is worth, but I have edited your response below to suit a stimulus:

The stimulus above, illustrates fossil records, a group of fossils which have been analysed and arranged chronologically (Source: Biology Dictionary). Fossil records provide extensive evidence regarding the 'Theory of Evolution', the theory that a change in a species over many generations is a result of natural selection of favourable characteristics. These records support the idea and are indicative of how Prokaryotic cells (3.5 Billion Years ago) evolved to become Eukaryotic cells (2 Billion Years ago), a process taking 1.5 billion years. It is the evidence of radiometric dating and comparative anatomy, that evidently fortifies this theory through an analysis of that species over time, thereby illustrating a progression of evolution. Hence, it is the evidence we are given by fossil records, like radiometric dating, that supports the 'Theory of Evolution'.

Remember, in Biology:
🧬 Always provide definitions of keywords
🧬 Address the stimulus (if given one)
🧬 Provide evidence to support your argument
🧬 Be as specific as you can be

I hope this has helped!

With this question, it's also important to address transitional fossils. That is, when we're talking about evolution, we're talking about going from Point A to Point B, and transitional fossils therefore show us that step between the two points.
