Record your observations about color,shape and any other key information- Positive or negative.
The image shows the simple staining of bacteria using methylene blue.
Methylene blue is recognised as a simple stain used for determining bacterial morphology. It is recommended for use in the staining of gram- negative bacteria found in spinal fluid.
Colour of bacteria stained : Blue
Blue stained bacteria: Indicates gram negative bacteria
Shape : Rod or bacillus
Stained pink : Gram positive bacteria, shaped like coccobacilli
Record your observations about color,shape and any other key information- Positive or negative. مو
Record your observations about colony size, color, texture (if
possible) and any other key information - positive or negative
gram.

Observations. Indicate whether each test was positive or negative and indicate what color each solution was after performing the tests. Describe what caused the observed results in the Benedict's Test for starch/saliva vs. starch buffer mixtures. Describe what caused the observed results in the iodine test for the starch/saliva vs. starch/buffer mixtures.
Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy AS. Note: if you have not been given enough information to decide a sign, select the "unknown" option. observations conclusions reaction AH is (pick one) Crystallization of a pure compound is A spontaneous only below-2. °C.
