    USYD ATAR cutoff leniency

    yeah haha that's the sad part coz they increase selection rank Honestly I'm slightly more inclined to USYD because obv it's a shorter degree (can do the Doctor of Physiotherapy course for 3 years but the standard 4 year one also allows you to become a registered & qualified physio), and also the...

    USYD ATAR cutoff leniency

    No way we're in the exact same situation! I also got UNSW ex sci/physio & ex phys but yeah, waiting for USYD phys if they release an offer. Good luck you've got this! 😀

    Biology questions help

    Yuh so for 18 we wanna find the individual (out of ABCD) common to both coz the stimulus explains how this person (who committed the crime) would have DNA from both (I & II). We know that II directly descends from B, so we wanna trace person B's lineage towards the left of the tree. Now we know...

    Mod B Help

    U probably already know but wherever u can try to link to Eliot's context especially stuff like the urbanisation, the nihilistic zeitgeist of Europe after WW1 etc. coz our teachers hv said that markers look fondly upon this stuff My class feels like its gonna be an extract Q this year from...

    flame test colours

    nah kidding here take a look at these Li, Na, K, Ca, Sr, Ba, Fe (2+ & 3+), Zn are the main ones (pb is the most important to know tho fr make sho u say that u GOTTA USE lead in the flame test 😏)

    Running list of key examples for Bio Trials/HSC

    yuh thats good

    Running list of key examples for Bio Trials/HSC

    yes those without resistance are outcompeted, which (bit of a stretch ik) but u can link this to how its unethical in a way coz it reduces the ability of other plants & species to survive

    Running list of key examples for Bio Trials/HSC

    GOOD but also ik im being a bit pedantic - towards the end just mention that even tho offspring is a clone of somatic donor, there still might be a bit of mitochondrial DNA from the egg cell of the mother, causing it to not be TRULY a clone of the dad (which you've already asserted at the end...

    Running list of key examples for Bio Trials/HSC

    For social considerations id say it allows for greater cotton products to be made & so benefits humanity in that way Economic - again due to greater production by farmers, they can earn more & it also creates more jobs in the economy for retailers & such to sell cotton Ethical say monocultures -...

    Running list of key examples for Bio Trials/HSC

    mention transduction vector agrobacterium tumifaciens which is used to transfer the BT gene into cotton And also mention how as the cotton "germinates" it produces the gene and thus acquires the resistance What is the result of decreased variation? Link this to higher change of succumbing to...

    Running list of key examples for Bio Trials/HSC

    nice example - now u can mention how the resistance has (sadly for other plants) resulted in a "monoculture" due to these wheat hybrids being resistant to pests & such, and can allow for the hybrid plants' species to to "out-survive their counterparts" (counterparts being other plants without...

    Gene Flow vs Genetic Drift --clarification

    bottleneck is the actual event, and results in founder effect ALSO could mention Hybrid vigour for gene flow - organisms with hybrid vigour increase variation/alleles wherever they go so that can accordingly increase/decrease variation in a pop

    Running list of key examples for Bio Trials/HSC

    vertical leaves prevent excess sunlight from reaching the plant, coz think about it less of the plant itself is exposed to the sun due to it being vertical (not horizontal) and so it can ensure the plant doesnt die due to the excess sun

    How does PCR work?

    yep exactly - u can also apply this to Sanger sequencing (the initial steps bcoz DNA must be amplified through PCR) but yuh overall nice

    maths trial tips?

    Are you doing CSSA?? Coz if u are I can sneak my phone in & see the Q's early & send 😈 (kidding) But fr as @SadCeliac said you got this believe in yourself - Finance Q I reckon will be loan repayments because they asked recurrence relation for annuities/investing last year didnt they? Even...
