Your Answer:

Three observations are;

The Gram status; either positive or negative
The shape, size and observe any motility
The presence of any chemical reactions




A lab researcher would be certain to note:
1. Size and shape
2. Any observable motility
3. Gram status (positive or negative)
4. The presence of any chemical reactions
5. Changes in color localized to the organism or the
surrounding media
6. Capture (or draw) images of any of the characteristics
described above




Question 3 pts


While observing an unknown sample of limited amounts, a researcher
must determine the following observations: (1) the presence of any
motility and (2) its Gram status using the same sample—the liquid sample
cannot be divided. Which would you determine first and why?


Your Answer:

I would first determine the presence of any motility before its Gram status;
because checking for presence of motility requires that you use a wet
mount. Gram status requires that you heat fix the sample and by doing
that the sample can be killed; also you cannot determine the presence of
any motility in Gram status that has been heat fixed. Since the liquid
sample cannot be divided, its most adviseable to check for the presence
of any motility first then you ca heat fix the liquid for for Gram status.

You must determine motility before determining the Gram
status. Motility requires a wet mount, while Gram staining
requires heat fixing the sample. If one were to begin with the
Gram stain the heat fixation process would kill the organism,
making any observations regarding motility impossible. The
correct approach would be to place the liquid culture on a
glass slide and determine its motility status. Next, the same
liquid culture can be heat fixed and Gram stained.




Question 4 pts


A facultative anaerobe is a microorganism capable of growth under what
conditions?


Your Answer:

Facultative anaerobe is a microorganism capable of growth under aerobic
and anaerobic conditions.




A facultative anaerobe is capable of growth under aerobic
(with oxygen) and anaerobic (without oxygen) conditions.




Question 5 pts


As Streptococcus is catalase negative would it thrive or die in the
presence of peroxides? Why?
