Stem Cells
Stem cells are cells which are found in multi-cellular organisms. They are symbolic for being able to renew themselves through a process called Mitosis and separate into a various range of specialised cell types. Two Canadian scientists, Ernest A. McCulloch and James Till, were responsible for the finding of stem plagiarizecells in the 1960’s. The two main types of stem cells that are found in mammals are: embryonic stem cells and adult stem cells. It is now possible to manipulate stem cells into specialised cells through cell culture.

Peer Reviews
Here's what a star student thought of this essay
Quality of writing
The writer has used terminology well to portray viewpoints. The answer is well crafted, in line with what is expected for this type of question at GCSE - it's overall structure follows this convention and works well. Overall, the answer is well written, however the examples should be expanded upon to increase the quality of the answer.
Level of analysis
As discussed above, the answer is evaluative, drawing a conclusion, with the candidate clearly giving their view as required for this type of question. However, the given examples, as mentioned above, should be more developed and brought back to the issue of heart disease treatment. The point about someone surviving to then go on and achieve something is good (GCSE looks for this drawing upon of other knowledge, not just scientific) but could be explored much more. Furthermore, sources of facts, such as heart disease killing someone every 34 seconds, should be cited to lend authority to the argument.
Response to question
The student has answered the question relatively well - they bring in the topic of stem cells before focusing in on their application in the treatment of heart disease. This narrows the answer's focus down well, but the supporting statement are relatively weak. They are not expanded upon enough or explored in much detail. Also, more points on both sides of the argument (for/against use of stem cells) should be put forward to bolster the argument.
