    Esterfication help!

    Esterificiation is a dehydration reaction and therefore requires a strong acid as a catalyst, citirc acid is triprotic but it isn't strong (i.e. doesn't fully ionize) and therefore won't cause dehydration Risk Process to manage risk Alkanol is flammable...

    how many of you need tutor for bio?

    As a tutor I'd recommend first Identifying what your problems areas (e.g. remembering the content for maintaining a balance, doing pedigrees and punnet squares for blueprint of life, or understanding the concepts in a way that allows you to answer the questions). Once you are sure of the stuff...

    Help! Please! I am trying to do a frist hand invest. to model natural selection!

    you build this into a model of evoution by natural selection if you increase the number of generations. 10 of each colour bean (I'd do 3 colours but I'm lazy) 2 people pick 5 each so 20 left, get the ratio of each colour left (e.g. 10 black, 8 red, 2 green) Put out 30 beans again but in...

    Sex Linkage (pedigree tree)

    Sec linked traits are present on the X or Y chromosome, however the Y-chromosome is small and the only disease gene that has every been even suggested for the Y-chromosome is one for a hairy ear condition. Therefore in human genetics when talking about sex linked we are talking about the...

    Gene expression? (OMG help please! T__T)

    Gene expression is the process by which the genetic code of the allele is used to synthesize a functional gene product (for hsc that would be a polypeptide or protein) Patterns of gene expression is what determines cell specialisation. What genes are turned on and at what times? Cells...

    How to study for bio

    I advise my students to study by structuring their notes as question and answer so that they can: 1. test themselves on the notes (read the question, cover the answer) 2. Do past papers (available from school or board of studies website) It does depend a little on your learning style...

    HELP! blueprint of life dotpoint

    Or you could talk about DNA sequencing which has created the Barcode of life database (BOLD) which we use to compare the DNA of animal species and thus elucidate there evolutionary relationships. One of the more interesting relationships that DNA sequencing has clarified the (relatively) close...

    LINKED GENES help!

    If two genes are linked it means that they are located physically close to each other on the same chromosome. Therefore independant assortment doesn't occur as it normally would and thus the offspring ratio isn't predictable in a simple mendelian manner. The 3:1 thing isn't actually right...

    HELP! blueprint of life dotpoint

    DNA sequencing was used to create the tree of life which has largely replaced the old five kingdom system of classification Tree of Life Web Project or you could talk about the use of DNA sequencing and phylogeny analysis that has revealed that whales and dolphins are closely related to hippos...

    PCR vs. Recombinant DNA

    In practical ab work the two techniques fulfil two related but different roles, remember that Recombinant DNA technology is a lot older so many of the things that we used to do with recombinant DNA we now do with PCR based approaches. However, recombinant DNA is still useful for a number of...
