Isolation, a dichotomous key and one confirming test take a mixed unknown to two defended names, each excluded candidate recorded, in this SC246 Unit 10 identification report. Searches like "sc 246 unit 10 assignment example", "sc246 unit 10 sample" and "sc246 unit 10 example" land here.
What a finished SC246 Unit 10 unknown identification report looks like
Five pages or so: purpose, isolation, a flow diagram, a results table, a discussion and references. Isolation describes the streak plate, the two colony types picked, and the purity check on each subculture. The flow diagram reproduces the section's dichotomous key and highlights the path taken for each isolate, with the candidates eliminated at every branch listed in a small box beside it. The results table gives each test, its purpose in one phrase, the medium, and the writer's bracketed read, in the order the tests were run. Identification lines read [Genus species] until the reads fill them. A confirmatory test outside the key, chosen because it separates the final candidate from its nearest neighbor on the list, appears last, and the discussion covers one ambiguous read.
How a SC246 Unit 10 example is structured
The report treats the key as an argument with premises, and every section serves that reading. Isolation comes first because a mixed culture produces nonsense at every branch, and the report says the purity check was what licensed everything after it. Tests appear in the order run, not in the order that would look tidiest, and each carries a stated reason: the Gram stain to split the key, oxidase to separate enteric rods from others, lactose to divide the enterics again. At every branch the eliminated candidates are named, so the identification arrives as the last survivor rather than a sudden answer. The confirmatory test is chosen for its power to separate the final two, and the report explains that choice. An ambiguous citrate read is repeated and reported both times. The conclusion states its confidence and what would overturn it.
Two isolates, each checked for purity
Two colony types are subcultured and checked before any test, because a mixed isolate sends a dichotomous key down contradictory branches from the first split.
A reason attached to every test
Each row states what the test was meant to separate, so the table reads as a sequence of decisions rather than a list of media.
Survivors named at each branch
Boxes beside the key record which candidates each read removed, and the identification appears only when a single name is left standing.
One confirming test chosen deliberately
An extra test outside the key is picked because it separates the final candidate from its closest neighbor, not because it happened to be on the shelf.
An ambiguous read reported twice
A weak citrate result is repeated, both outcomes are shown, and the report explains which branch it followed and why that choice holds.
Where marks go in SC246 Unit 10
Identifications with no path behind them earn little even when right, because the rubric typically weights the reasoning above the name, and a correct guess shows none. Skipping the purity check on isolates undermines every later read, and graders ask about it directly. Results listed without purpose, a column of pluses and minuses, hide why each test was chosen. Changing a read to fit the expected organism, rather than reporting the conflict, is treated seriously almost everywhere. Keys followed past a branch the data did not support, choosing a direction on a weak read without repeating it, lose method marks. Confirmatory tests that fail to separate the last two candidates add length without evidence. Media names misspelled, organism names formatted inconsistently, and missing references cost points at the edges.

SC246 Unit 10 questions, answered
What if my unknown matches two organisms on the list?
Then the report says so and explains which additional test would split them. Two survivors after the key is an honest outcome, especially when one read was weak. Graders generally prefer a report that stops at two with a clear next step over one that picks a name the data do not support, and the reasoning section can make that case directly.
Do I have to follow the key in order?
Usually the section's key sets the order, and the report should follow it or explain any departure. Running an extra test early is sometimes practical, but the write-up still presents results as the key uses them. The point is that each read eliminates something, and a reader can check the path branch by branch without reconstructing it.
How do I handle a test that gave no clear result?
Record it as ambiguous, repeat it if time allows, and report both reads. If the repeat still disagrees with expectations, follow the branch the stronger evidence supports and say why. A weak read buried inside the table is the kind of thing a grader notices; one stated openly usually costs nothing and often earns credit for judgment.
