yes all HBonline, lectures and pracs are covered in assessments according to info on webct

just wondering, if I do decide to drop from the advanced unit (chem in my case), does my time table change? Thanks in adv

I think the allele for O is i not I^O, it's the recessive alelle of the three

+1 something about the eventual eliminitation of the disease etc

Re: Hsc 2009 bio exam if the stomatas need to be open at night for gas exchange wouldnt they need to have a larger stomata size? B shows their stomata size is smaller at midnight indicating theyre closed so wouldnt that make it wrong?

Re: Hsc 2009 bio exam 15 cant have been B, if species 1 is a fungi, it cant be killed by antibiotics because antibiotics only affect bacteria, I think D was the only correct answer

i was tossing up between putting cystic fibrosis in there because its not caused by mutation, its caused by inheritance of homozygous recessive inheritance. so I ranted on about down syndrome and the potential of gene therapy cause the question asked "could lead to management...using gene...

The inheritance of linked genes leads to the simple Mendelian ratio 3:1 because the alleles are on the same chromatid and the whole chromatid moves completely to the new cell. Only if crossing-over occurs will this ratio change, which is the case for dihybrid crosses giving the 9:3:3:1 ratio. I...

Im assuming this is the secondary sources investigation to "describe a methodology in cloning", I chose to describe therapeutic cloning for organ transplants or for the treatment of diseases 1. DNA is extracted from affected patient 2. DNA is inserted into a donated enucleated egg (nucleus...

same situation as you haha, except for our number one who actually has a chance, so hopefully he brings us up

as for 18 a) (ii), a female would need to have 2 copies of the recessive allele (one on each X chromosome) to show the sex-linked conditions of DMD. One of these alleles would thus need to be inherited from a father who also suffers from DMD. Males with DMD are weelchairbound and rarely live...

no that can't be right, the two homologous chromosomes should be the same size, so the pairs are the two longer ones and the two shorter ones with the same letter representing corresponding alleles. The genotype should then be Aa, Bb, CC and Dd

I hate these questions, I always thought relevance and validity meant the same thing, where research or experiment being carried out is relevant to the intended study, i.e. the method actually investigates the aim. As for reliability of sites and books, if they are written by a person of...

my teacher thoroughly emphasised the use for "agricultural purposes" and so advised we chose examples like sheep and wheat. I chose wheat and have a pretty lengthy history of it to show the series of changes, but im not actually sure if its supposed to be this detailed haha: History of Wheat...

The only answer I can think of here is the use of cross-breeding experiments, which identifies the relative position of linked genes (i.e. if theyre on the same chromosome). They examine the frequency at which linked genes are separated, thus calculating the distance between them where 1%...

partical moving SHM has acceleration= -9x, x=metres, t=seconds x=asin(3t + B) is a possible equation for motion initially accleration= 18 m/s2, after 5pi/18 seconds velocity=12 m/s. Show the amplitude =4m and particle moving along a horizontal line has an acceleration = -4x, x=metres...

My copy has a 2 what the effff bro, anyways thanks for that lol
