Do we need to know much about Burnette Macfarlan? Or just know the stuff he discovered since its pretty relevant? Edit: Also do we need to know how cytptoxic t-cells kill infected cells? e.g releases perforin. How much detail is needed on the effectiveness of vaccination programs for small...

A) DNA or deoxyribonucleic acid is in the shape or a ladder. where the sides consist of phosphate and sugar (deoxyribon). Attached to the sugar is the 'rungs' of the ladder. These 'rungs' are made of 2 of the 4 nucleotides thymine, cytosine, guanine and adenine. The shape of each of these...

I think the Cochlea is the overall sort of structure then the organ of corti is more specific and the coil in the middle of the cochlea

Its when the first stage of division takes place(dont know the phase names and pretty sure you dont). The homologous chromosomes aline them selves in the middle and that process is random which is random segregation. Then they split to form 2 daughter cells with each having 46 chromosomes and...

Diffusion would never be sufficient as the concentration would always be extremely high in the tubules as they have just been filtered out in the bowmans capsule. So any diffusion that would take place would be the random movement of particules from the tubules to capillaries therefore active...

They always bloody came up in our school exams lol always 4-7 marker but havnt really look at past HSC gonna do that tomorrow oh wait later today lol ahhh forgot about reliability, validity and accuracy although u can normally have just some pretty broad answers that covers them thx though

Yeah so the questions just basically know method some general safety precautions and variables and control/ equipment ect ect hmm if i would have to hav a guess model natural selection, kidney disection or enzymes one although that one would be a massive question so it may just ask for temp or...

gez 5 marks. Health is not simple the absense of disease but a combination of the health components e.g physical, emotional, socially that perform in a coordinated funtion. Very subjective which is where it becomes difficult in defining for example a person who has diabetes is going to have a...

A threshold is the minimum stimulus required to generate a pesonse in the nerve cell. Without a minimum threshold, nerves would respond too readily to all incoming stimuli. The reaction will only occur if a stimulus is of sufficient magnitude to pass the threshold. not all stimulus will generate...

Law of segregation=law of independant assortment? not sure :/ Law of segregation has to do with meiosis and when the homologous pairs line up in the middle of the cell before they split their position is random therefore leading to increased variation. To understand it to a great deal need...

probably most of it if its and 8 mark question. guess it depends of the question. But its in the syllabus so they could ask it. Can probably generalise it thou like 1890's Manson discovered etc etc and Golgi discovered....

Heres some notes on the historical developments – 4 BC: Greeks thought that the symptoms of malaria were caused by either breathing in marsh vapours or bites of insects that live in marshes – 1880: Laveran observed micro-organisms in fresh blood from malarial patients and...

Pretty much just an enzyme that speeds up the part where nucleotides join to the single strands of DNA.

Yeah dont need to talk about influenza its just their for a sort of explanation or stimulus.

Depends on how much its worth i guess because it does say talk about the impact on the genetic diversity so you might not have to include that info.

Producing banana trees by asexually reproduction produces offspring with the same genetic material as the parent. This can be beneficial as all plants will have identical requirements grow in similar ways to produce similar yields at the same time. As well as this the plants that have desirable...

Describe the process of DNA replication and explain its significance.

Is blood type (e.g AB) an example of incomplete dominance?
