The following is based on the Assignment Response Checklist which some lecturers
may use to correct your work. Even if they are not using this checklist, the
corrections shown here are mostly very common ones, and you can see from the
examples how they apply to your own writing.
The marking of your essay has involved the use of an assessment tool - the
Assignment Response Checklist. The Checklist is used to identify any problems in
your writing (grammar, paragraph structure, citations, etc.) and is designed to
give you some idea about areas which you should try to improve in. Note that the
content of your essay is dealt with separately in the form of written comments.
On your marked essay, you may find a number of symbols written in the margins.
To interpret these symbols, refer to the Assignment Response Checklist below. Look back at your essay and try to work out precisely where
problems lie. Make any necessary changes to your work.

| Biology Essay |

|
| Despite many efforts to eradicate malaria, it is still common today. Discuss the |
|
| biology of malarial resistance and new prospects for its control. |
|
| |
|
| Presently malaria is regarded as one of the most serious health threats in the world |
|
cit
| (Smith). It is most prominent in the tropics including countries such as New Guinea, |
|
| Indonesia and numerous African countries, and is considered to be a parasite. A | ss
|
| parasite being an organism which lives on or within another organism. The parasite |
|
| uses this organism (the host) to sustain its life and, in the case of malaria, often kills the |
|
| host. Malarial parasites are of the genus Plasmodium and spent part of their life cycle | tc
|
| in humans and the rest in Anopheles mosquitos called vectors. Sporozoites are found in |
|
sr
| the salivary glands of these vectors and when an infected feeding female Anopheles |
|
| pierces the human skin with her proboscis and injects her saliva into the wound, the |
|
| numerous parasite cells are released in to the blood stream and work their way to the | sp
|
| liver and lymphatic system where they then multiply and spread rapidly to all parts of |
|
| the body. |
|
| |
|
| People can be infected with malaria once, twice or a number of times. It is not | att
|
| correct to say that because a person has been infected once, that they are totally |
| immune. However, it is the case that people who have been infected a number of times |
| do acquire some immunity. This simply means that without drugs, the number of |
sr
| parasites in the blood decreases, and there are no visible signs or symptoms, this |
|
| person is not at any great risk of death and is considered a 'carrier', which means that |
|
| they can pass on this infection to others because when a mosquito bites them, it picks |
|
| up the parasite and infects other individuals. |
