If u have any questions in particular feel free to ask

Hi - this isn’t so much as a study tip but how u approach yr 11.
I think it is very important to know that yr 11 will be challenging but it is just practise for yr 12. This means that u might drop subjects or get grades lower than u may be used to.. but that is ok!! It is all about gaining experience of SACs, studying, managing a heavier workload etc

• one thing I will say if that if u are doing a yr 12 subjects heavily focus on the yr 12 subject!! Even if it means u won’t study for a couple of Sacs for yr 11… studying for yr 12 takes the most priority

Basically - yr 11 is a challenge but it is practise for yr 12 don’t put too much pressure on urself u will figure it out : )

Thanks so much!

hi everyone, next year I am starting year 12 and I am taking 3/4 chem. I’ve heard that the jump to 3/4 from 1/2 is very significant in vce and was wondering if anyone had any advice of how to not get overwhelmed with the new content and workload next year? thanks!!

Thank you so much!

Does anyone know what biological implications mean? Such as when they ask for a biological implication about GMOs. I am struggling to find out what the term actually refers to. Thanks!

Hi, all we need to know is the exact number of ATP produced in aerobic and anaerobic respiration. Other than that no specific number is required.
Aerobic respiration: 30 or 32 ATP
Glycolysis: 2ATP
Kreb's cycle: 2ATP
ETC: 26 or 28 ATP

Anaerobic Fermentation:
2ATP

I was doing the same practise exam yesterday (neap 2022) ahaha.

So biomass is plant or animal material that can be sourced from various industries that have carbon rich compounds that glucose and other sugars can be extracted from. The biomass itself is the source of glucose and sugars as an input for fermentation. Then to produce bioethanol, Yeast is added to this biomass after it has been broken down to anaerobically ferment and produce ethanol as an output.
Therefore C would be incorrect because it cannot provide sugars and glucose for anaerobic fermentation. Although, I can see why you went with this answer.
D is the correct answer because wood pulp contains cellulose, which be broken down to produce glucose.
if this is still confusing or u have another question feel free to ask

According to the Edrolo textbook these are the organelles you need to know for the direct production, transport, modification and eventual secretion of a protein:

1. Ribosome - site of protein synthesis
2. Rough Endoplasmic Reticulum - involved in initial folding of protein and transport to Golgi Body
3. Transport Vesicle - transports protein to Golgi body.
4. Golgi Body - Modifies proteins and then packages them into vesicles.
5. Secretory Vesicle - Transports proteins around the cell and fuses with plasma membrane to secrete proteins into the extracellular environment.

There are other organelles indirectly required for this process like mitochondria that produces ATP for the process but since it is not directly involved you are not required to write this is your answer. Hope this helps!

I am not sure if this question is correct. I have completed the same question before on a practise exam but the first option was different:
Question 17
What is the difference between C3, C4 and CAM plants?
A. Unlike C3 and C4 plants, CAM plants, such as cactus, absorb carbon dioxide (CO2) at night.
B. C4 plants immediately integrate CO2 into a 3-carbon compound, whereas C3 and CAM plants
initially integrate CO2 into a 4-carbon compound.
C. C3 plants absorb more CO2 during the day, whereas C4 and CAM plants absorb more CO2 at night.
D. CAM plants are suited to temperate climates, C3 plants are suited to dry environments and C4 plants
are suited to marine environments

This would make option A correct as CAM plants have the adaptation to absorb CO2 during the night to separate the light dependent and light independent stage by time. I am not sure what happened with the question on your end, maybe double check your question or look at where it is originally from?

So if it was a predator that came and ate all of the darker barnacles and the grey ones survived it would be natural selection. But since it was a natural disaster (heatwave) that has changed the gene pool then the bottleneck effect is specifically what is happening?

Thanks so much I really appreciate it!

Can someone please help me with this question? It is from the 2023 Northern Hemisphere exam, so there are no answers available.
DNA evidence from present-day humans shows that Homo neanderthalensis interbred with
H. sapiens while the two species coexisted in Europe. Fossil discoveries show that H. erectus
and H. sapiens coexisted in Indonesia about 143000 years ago.
Explain whether you would expect scientists to find DNA evidence to support the view that
H. erectus and H. sapiens interbred?

thanks
