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.

They both have a bilipid cell membrane. This means that their cell membrane is composed of phospholipids. Both cells also have ribosomes. This is a critical cell organelle that is involved in the translation of mRNA to proteins. Their genetic material is also made up of deoxyribose sugars (DNA).
Regent's Park, is trying to communicate the SCALE of the exotic animal by comparing it to the nine onlookers behind it. A scale is a unit used in mathematics.
<h3>What is a scale?</h3>
Scale is a characteristic of an object that does not change when it is multiplied by a given unit, thereby showing universality.
The units of scale in mathematics and physics include, among others, length and energy.
The value that is multiplied in a given scale is called 'common factor' and it is used to show universality.
