B, because in all truth and honesty, stress is truly inevitable. Also, use process of elimination. I hoped that helped :)
A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular.Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall. When looking under a microscope, the cell wall is an easy way to distinguish plant cells.
Difference Between Plant And Animal Cells 1 Chloroplast. Like animal cells plant cells have mitochondria. 2 Cell Wall. Animal cells do not contain a cell wall while plant cells and fungi cells do. 3 Vacuole. Vacuoles are very large membrane-bound sacs within plant cells.
Gamates cells have half the chromosomes
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.
