Thew correct answer is amino-acids

Amino acids are essential to all life on earth. They are organic molecules comprised out of the amino (NH2) and acidic ( COOH) compound. The twenty amino acids can bound to one another with peptide bonds and form different complex structures called proteins. Proteins are important structural part of cells, enzymes and hormones, and without them the life as we know couldn't exist.

nikitadnepr [17]

The answer is invasive species.


Invasive species are species that are not native to specific ecosystem, but they have a capability to spread widely through the ecosystem, This way they can threaten native species of the ecosystem or cause environmental harm. 

<span>After being introduced into the Black Sea, they greatly affect local ecosystem. In the new area, they have no natural predators and are able to spread. If they spread beyond the area they are introduced, they become invasive species which can overgrow native biotopes and are a great threat to the local biodiversity. This could lead to the extinction of some native species.</span>

Dr. Paul Ehrlich observed that the differential stain developed by Dr. Gram suggested bacteria could be killed differentially by
Alex787 [66]

Answer:

The correct answer is Glycocalyx, ribosome and cell wall.

Explanation:

Glycocalyx is mainly found in bacteria that makes a protective covering outside the cell wall in the form of capsule of bacteria and provide protection to bacteria from host immune cell.  

Bacterial ribosomes are different from human ribosomes. Bacteria contain 70s ribosome while humans contain 80s ribosome so ribosomes are potential targets for many drugs present today.

Bacterial cell contain cell wall which is made up of peptidoglycan or lipopolysaccharide but human cell does not contain a cell wall, therefore, many drugs are designed to destroy cell wall of bacteria like penicillin.

So glycocalyx, ribosomes, and cell wall can be potential targets for Dr. Ehrlich's "magic bullets" due to significant difference or absence from humans.
