Answer:
a. No discrepancy is present; organisms that contain an outer membrane and periplasmic space should stain pink because of their cell wall composition.
Explanation:
Gram stain is the staining method used to differentiate bacterial species into two groups, gram-positive and gram-negative bacteria. Factors that will differentiate gram-positive from gram-negative include the coloration of bacteria, the composition and chemical and physical properties of cell walls. In these tests, bacteria that have an outer membrane and a periplasmic space are considered gram negative and pink in color (sometimes similar to red) due to their cellular composition. For this reason we can state that there is no discrepancy present in the bacteria exposed in the question; Because this bacterium has an outer membrane and a periplasmic space, then it is normal for the bacteria to turn pink due to its cell wall composition.
Reduction occurs when a molecule gains an electron or decreases its oxidation state.
the following is formed when a group of tissues works together to perform a common function is called an Organ.
<h3>What is the definition of organs?</h3>
The word organ derives from the Latin term organum (instrument, tool). These structures are objects of physiology, the area of biology that studies how organisms, systems, organs, cells and molecules perform chemical and physical functions in the body.
In this case, is correct to say that an organ is formed when a group of tissues works together to perform a common function.

Male Birds are usually the colorful birds to attract mates while females are camouflaged to protect their eggs/hatchlings. Ground birds need to be camouflaged because they are easy prey and they have their nests on the ground.
Answer:
Qualitative observations are those that cannot really be counted or measured by empirical figures, but are rather described by the features they have such as their color or taste.
Quantitative observations can be measured and counted by empirical figures i.e. numbers such as age and temperature. Number operations such as addition can be performed on them as well.
Qualitative observations.
- The shirt is soft and red.
- The river flows more quickly in the spring than in the summer.
Quantitative observations.
- There are eight elephants over the age of six at the zoo.
- It is 72 degrees Fahrenheit outside.
