This mark scheme is published as an aid to teachers and learners, to indicate the requirements of the
examination. However, we have not been able to adjust it to reflect the full range of answers that would
have been seen as a part of the normal moderation and marking process, and it does not necessarily contain
all the possible alternatives that might have arisen.
Cambridge will not enter into discussions about the mark scheme.

General guidelines on marking
Many descriptive answers can be expressed in a variety of ways. Professional judgement
can be used in these cases, providing it matches the marking points and further information
in the mark scheme.
Answers may have words spelt incorrectly. Credit is normally given for phonetically correct
answers, unless the word has a scientifically different meaning. For example, where the answer
should be antennae, credit will be given for antena but not for anthen (too close to anther).
Only the science is being assessed so answers do not need to be grammatically correct.
Significant figures will be indicated in the question or in the mark scheme.
Unless specified all marking points are independent.
Annotations and abbreviations
/ or alternate responses for the same marking point
( ) brackets the words or units in brackets do not need to be stated, for example,
(recycles or releases or provides) minerals = minerals scores the mark
underline exact word is required
Accept an acceptable response
Do not accept indicates an incorrect response that would contradict another otherwise
correct alternative
Ignore indicates an irrelevant answer that is not creditworthy. Full marks can
still be achieved even with answers that are ignored.
Note provides extra information when necessary
ecf error carried forward; marks are awarded if an incorrect response has been
carried forward from earlier working, provided the subsequent working is
correct
ora or reverse argument; for example, as mass increases, volume increases
could be written as mass decreases, volume decreases
