<h3><u>Answer;</u></h3>
peptidoglycan
The molecular basis of the Gram stain is the amount of<u> peptidoglycan</u> in the bacterial cell wall.
<h3><u>Explanation</u>;</h3>
- Gram stain is differential stain that is very useful for identifying and classifying bacteria as either gram negative or gram positive.
- Gram negative are those that decolorize easily, such as E. coli, while Gram positive are those that retain the primary stain and do not decolorize easily.
- The result depends on the bacteria cell wall structure, the cell wall of a Gram-negative bacterium is composed of 20 percent or less of peptidoglycan.
Convergent evolution in my understanding is the independent evolution of similar features in species of different lineages.
Answer:
I don't know like what does it basically mean??
Bacteria were first observed by the Dutch microscopist Antonie van Leeuwenhoek in 1676

The condition called parasitism is characterized as a non-symbiotic relationship. Thus, the correct option is C.
<h3>What is Parasitism?</h3>
Parasitism may be defined as a type of +,- interaction in which the population of species 1 is benefitted while the population of species 2 is harmed.
In this type of interaction, one organism feeds on other but does not kill it. And even some parasites like tapeworms are attached to their hosts for most of their lives.
Thus, the correct option for this question is C.
