A bacterial cell that contains an outer membrane and periplasmic space stains pink to red on Gram stain. Which one of the follow
anastassius [24]

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.

We think of termites as insects that eat wood. However, termites cannot digest the wood and rely on a variety of eukaryotic and
omeli [17]

Answer:

Obligate mutualism.

Explanation:

Obligate mutualism: It is defined as each organisms are obligated to each other, they rely on one another, means one species cannot survive without the other species. It may involve the interchange of resources, for example food, shelter, and nutrients or may interchange services like transportation, and protection.

Termites are mutualistic related to protozoa which lives inside the insects gut. Termite gets benefits from the bacterial symbiont ability which is present in the protozoa to digest the cellulose. The termites do not have this ability to do this, without the help of protozoa. They are not able to use their energy from the food which is wood, cellulose comes from wood it chews.

So, termites are mutualistic related to protozoans and showing obligate mutualism.
