The danger of this very-by-subject organization is that your paper will simply be a class of points: a certain number of points in my drumbeat, three about one subject, then a certain classic of points about another. This is far not what college instructors are looking for in a higher-generally they want you to make or contrast two or more children very directly, rather than just work the traits the things have and waiting it up to the reader to reflect on how those people are similar or different and why those interiors or differences matter.
Thus, if you use the research-by-subject form, you will generally want to have a very strong, reverse thesis and at least one body paragraph that ties all of your personal points together. Point-by-point Rather than undergraduate things one subject at a family, you may wish to fulfill about one point of comparison at a controversial.Through a network of UK and overseas offces, Edexcels centres receive the support they need to help them deliver their education and training programmes to learners. ResultsPlus is Edexcels free online service giving instant and detailed analysis of your students exam and mock performance, helping you to help them more effectively. Examiner Comments Many candidates fail to provide enough details to demonstrate a clear understanding of their reasoning.
Info to be updated here] It is down to personal preference which you use. You will also need the Answers to the Student Book questions as these are not provided with the book, though Pearson Edexcel supply them online as a free pdf. This is an excellent answer - not only stating that there would be little genetic variation, but also explaining how this would increase the validity of the results. It cannot be emphasised too much how important it is to read all of the information provided in the question.
Although this stage may be performed in schools and colleges by laboratory technicians instead of the students, it is important that they are aware of the processes, especially the need for aseptic techniques to minimise contamination of the plate. Although this answer is not neatly presented and parts have been crossed out and extra parts added in, it does demonstrate how a plan could have helped this candidate produce a tidier response. However, there were many who failed to observe that both groups of dogs were from breed P and wrote answers that assumed the two sets of results represented different breeds, for example stating that there were 'more dogs of breed P'.
References to speed or rate were irrelevant as there was no time factor involved.
Variety B has fnally been identifed as having the highest mass of calcium ions. It was not enough to state just one characteristic that domain B shared with domain C, as it also shared one characteristic with domain A. A well learnt response using correct terminology, although it is better to describe stem cells as giving rise to other cells rather than becoming other cells. Examiner Tip 20 GCE Biology 6BI02 01 Question 4 c i This question was well answered on the whole, with most candidates able to identify which portion of the chromatid would be swapped over. Two marks were awarded here for circular DNA drawn as a complete loop with no loose ends, and ribosomes - it was not necessary to state that their size was 70s. Despite the many opportunities made available for candidates to demonstrate their knowledge and understanding in this paper, marks were frequently lost because terminology was not used precisely.
Few candidates seemed to understand that the frequency of favourable alleles in a population increases over several generations, that is over time, and not immediately. However, there were many examples of muddled answers, where it seemed as if candidates were under the impression that it was either the ribosomes or the vesicles that were being transported and modifed. The author has a website, Biology Resources , with answers to all the questions in the book and additional self-assessment question sheets and answers that can be printed out. This is an excellent answer - not only stating that there would be little genetic variation, but also explaining how this would increase the validity of the results. Although this example is less precise, it still achieved full marks.
A lot of candidates appeared to believe that seeds would be genetically identical if coming from the same plant, as if they had been cloned. Good candidates correctly worked out that the cell with none of the genes switched off was the totipotent one. The course is features over a 70 videos ranging from 15 mins to 1 hour, online assignments, self assessed assignments as well as mock exam questions throughout the course. Most subjects will be marked onscreen using ePEN, w A few
Examiner Comments This response only scores 1 mark for identifying variety B. Note that Pearson Edexcel always provide answers to all questions in their Student books - sometimes on a CD-ROM that comes with the book and sometimes as a download from their site. Although this example is less precise, it still achieved full marks. Despite the many opportunities made available for candidates to demonstrate their knowledge and understanding in this paper, marks were frequently lost because terminology was not used precisely.

The candidate uses relevant terminology accurately making it evident that they have a sound grasp of the process of mitosis. After correctly identifying cell C as the totipotent stem cell, this candidate then refers to genes not being switched off, notes that there are genes in a human cell and then clearly states that cell C can therefore differentiate into any cell type. However, many candidates just repeated the information provided in the stem of the question, such as 'the results overlapped' which could not be awarded any marks. He found the book interesting and comprehensive, and all answers were easily available.
Examiner Tip GCE Biology 6BI02 01 13 This is an example of a very common error made on this question - assuming that seeds from the same plant will be genetically identical. This part of Q6 was also assessed for QWC and, on the whole, technical words were spelt correctly and answers were presented logically. Candidates could score high marks, even if they did not recall the term 'cisternae', as long as their descriptions were suffciently clear. Stating that it is 'half the diploid number' may seem logical, but it does not explain what the terms mean. Candidates who drew circles around the actual structures were credited on this occasion, but it is important to follow instructions precisely.
Many responses discussed the relative strengths of the two types of rope, whereas the question just asked for a comparison of the effect of increasing diameter on the mass needed to break the two types of rope. A few s Poor expression of ideas can come across as lack of knowledge, especially when terms such as 'gene' and 'allele', 'species' and 'individual' are used interchangeably.
Although this example is less precise, it still achieved full marks. Examiner Comments 38 GCE Biology 6BI02 01 b i - a very precise response, covering all bases, not only stating that ethanol gave a larger zone of inhibition in three out of fve species, but also identifying them as B1, B2 and B4. This response does exactly as the question instructs - the labels of the haploid structures that are fertilised are both circled. The author has a website, Biology Resources , with answers to all the questions in the book and additional self-assessment question sheets and answers that can be printed out.
